DETAILED DESCRIPTION
(21) As noted above, the present disclosure relates to wireless networks and communications including, but not limited to, broadband interne services to end user, security and/or automation systems, as well as narrow beam mesh networking and related operations and techniques.
(22) In one aspect, disclosed herein are systems and methods that relate to wireless mesh networks (e.g., narrow beam mesh networks), associated systems, and operations relating to network communication, including, in some embodiments, adjustments and modifications. The disclosed systems and methods may facilitate designing, operating and/or adjusting/modifying wireless networking communications. In some embodiments, the disclosed systems and methods relate to and account for wireless communication nodes that are capable of establishing point-to-point extremely narrow beam communication link, point-to-point steerable extremely narrow beam communication link, point-to-point multiple extremely narrow beam communication link, point-to-multipoint narrow beam communication links, ultra-wide-band point-to-point communication link and a combination of point-to-point and point-to-multipoint communication links, among other possibilities.
(23) In another aspect, disclosed herein are systems and methods that relate to the design of millimeter wave mesh networks, associated systems, and operations relating to network communication, including, in some embodiments, adjustments and modifications. In some embodiments, the disclosed systems and methods relate to and account for designing and constructing a wireless mesh network with long hop links and/or short hop links.
(24) As one example to illustrate,
(25) Tower/fiber access points 101 and 102 can be co-located or can be located at different physical locations. Tower/fiber access points 101 and 102 have access to high bandwidth dark fiber capable of providing up to several hundred gigabits/second of data throughput. Tower/fiber access points provide backhaul connectivity between the core network/data center (not shown in
(26) Specifically, fiber PoP 101 is connected to wireless communication node 103 via the long hop link 120 that is capable of operating on high bandwidth (multiple gigahertz) signals operating at very high frequency (e.g., 6 Ghz˜100 Ghz such as 28 Ghz, V band, E band, etc.). Similarly, fiber PoP 102 is connected to wireless communication node 106 via the long hop link 124 that is capable of operating on high bandwidth (multiple gigahertz) signals operating at very high frequency (e.g., 6 Ghz˜100 Ghz such as 28 Ghz, V band, E band, etc.).
(27) In addition, wireless communication node 103 is connected to wireless communication node 104 via long hop link 121, wireless communication node 104 is connected to wireless communication node 105 via long hop link 122, and finally wireless communication node 105 is connected to wireless communication node 106 via long hop link 123 as shown in
(28) The long hops link 120, 121, 122, 123 and 124 may have longer length compared to short hop links. For example, in one embodiment, longer hop links can have 500˜600 meters length. In a different embodiment, long hops links can be shorter or longer than 500˜600 meters.
(29) Communication network 100 also comprises a number of short hop links as shown in
(30) Similarly,
(31) Likewise,
(32) In this respect, the path of short hop links that connect wireless communication node 103 to wireless communication node 104 is shown to consist of 5 intermediary wireless communication nodes 107-111 and 6 short hop links 125-130. Similarly, path of short hop links that connect wireless communication node 104 to 105 and 105 to 106 each consists of 4 intermediary wireless communications nodes and 5 short hop links. However, it should be understood that wireless communication system 100 can have any number of intermediary nodes in the path of short hop links that connect two wireless communication nodes that are already connected directly to each other via long hop link.
(33) In accordance with the present disclosure, the use of long hop links in combination with short hop links greatly reduces the maximum number of hops that data packets need to pass in order to transport packets between an end user and a fiber PoP. For example, consider an end user associated with wireless communication node 113. In the absence of long hop links 121, 122 and 123, a data packet originated from an end-user connected with wireless communication node 113 would pass through a large number of intermediary wireless communication nodes. For instance, in the event where a packet needs to be transmitted between fiber PoP 101 and wireless communication node 113, the packet would go through 8 intermediary nodes including 112, 104, 111, 110, 109, 108, 107, and 103 under such a scenario where no long hop links are available in the mesh network. However, as shown in the
(34) The example above shows how an end-user associated with wireless communication node 113 can benefit from the presence of long hop links for improving the latency or packet delay. However, it should be understood that end-users associated with a large number of wireless communication nodes (especially the ones that are indirectly connected to wireless communication nodes with long hop links) can benefit from the presence of long hop links to improve network latency or packet delay. In addition, the presence of long hop links improve the reliability of the network by increasing the number of available wireless mesh network paths between the source and the destination. For example, an end user associated with wireless communication node 113 can take A) a path consisting of intermediary nodes 112104
103
101, B) a path consisting of intermediary nodes 112

102 to connect to the core network. These alternative paths increase reliability of the overall network. For example, in the event that short hop link 125 fails, option B described above for the end user of wireless communication node 113 may not be available. However, other options including A, C and D may still be available to transfer packets or traffic between wireless communication node 113 and the core network.
(35) Bi-directional communication links 120 to 140 shown in
(36) In
(37) Referring to
(38) For example, long hop links 242 and 243 that connect the nodes 201 to 206 and 206 to 207, respectively, form a segment of long hop links (1st spoke). Similarly, long hop links 244 and 245 that connect node 201 to 208 and 208 to 209, respectively, form another segment of long hop links (2nd spoke). Likewise, long hop links 246 and 247 that connect node 201 to 210 and 210 to 211, respectively, form another segment of long hop links (3rd spoke). In the same manner, long hop links 248 and 249 that connect node 201 to 213 and 213 to 212, respectively, form another segment of long hop links (4th spoke). Similarly, long hop links 238 and 239 that connect node 201 to 202 and 202 to 203, respectively, form another segment of long hop links (5th spoke). Similarly, long hop links 240 and 241 that connect node 201 to 204 and 204 to 205, respectively, form another segment of long hop links (6th spoke).
(39) The different spokes that are formed from segments of long hop links are also interconnected via long hop links. For example, the 1st spoke and 2nd spoke are connected via long hop link 281. Similarly, the 3rd and 4th spokes are connected via long hop link 282 and the 5th and 6th spokes are interconnected via long hop link 280 as shown in
(40)
(41) The example network layout in
(42) Similarly, wireless communication node 204 is connected to wireless communication node 218 via short hop link 255, wireless communication node 218 is connected to wireless communication node 219 via short hop link 256, wireless communication node 219 is connected to wireless communication node 220 via short hop link 257, wireless communication node 220 is connected to wireless communication node 221 via short hop link 258, and wireless communication node 221 is connected to wireless communication node 205 via short hop link 259 to form a segment of short hop links that connects the wireless communication node 204 and 205, thereby providing an alternative path between nodes 204 and 205.
(43) Likewise, wireless communication node 206 is connected to wireless communication node 222 via short hop link 260, wireless communication node 222 is connected to wireless communication node 223 via short hop link 261, wireless communication node 223 is connected to wireless communication node 224 via short hop link 262, wireless communication node 224 is connected to wireless communication node 225 via short hop link 263, and wireless communication node 225 is connected to wireless communication node 207 via short hop link 264 to form a segment of short hop links that connects the wireless communication node 206 and 207, thereby providing an alternative path between nodes 206 and 207.
(44) Similarly, other short hop links ranging from 265 to 279 connect a number of wireless communication nodes to each other. Nodes belonging to different spokes or segments of long hop links can also be interconnected via short hop links. For example, node 224 and node 228 are associated with two different spoke or segments of long hop links. However, both 224 and 228 are connected to another wireless communication node 283 via short hop links 284 and 285, respectively, thereby creating a path along wireless mesh network that can connect nodes associated with different spokes via short hop links in addition to long hop links 280, 281 and 282 described above.
(45) In addition, it is also possible to connect any to adjacent spokes via direct long hop links. For example, although not shown in
(46) Referring to
(47) In accordance with the present disclosure, as noted above, the disclosed wireless mesh network can be built in phases. For example, as shown in
(48)
(49) According to another aspect of the present disclosure, the disclosed systems and methods may relate to and account for designing and constructing a wireless mesh network comprising high-capacity long hop links.
(50) As one example to illustrate,
(51) Specifically,
(52)
(53) In one embodiment, very high capacity long hop links can provide several Giga bits of capacity. For example, 601-1 to 601-6 very high capacity long hop links in
(54) Bi-directional communication links 601-1 to 601-6 shown in
(55)
(56) In one embodiment, the threshold can be based on the rain fade margins that guarantees certain data rate or capacity of a link based on a certain amount of rain per unit time or rain zone of a geographical area. That means that although a very high capacity long hop links can have a link length greater than the radius of the cell shown in
(57) In one embodiment, the threshold can be within a 1 to 2 mile range. In another embodiment, the threshold can be greater than a 1 to 2 mile range or less than a 1 to 2 mile range. Based on the above description, this also implies that all seed locations (e.g. Seed A to Seed F in
(58) It should be understood that while communication Network 600 in
(59) In addition to fiber PoP node 601, very high capacity long hop links 101-1 to 101-6, and seed homes A to seed home F,
(60) As noted above, the use of long hops links can greatly reduce the number of hops required by the data packets between the end user and the core network. For example, consider node 1000 that is located at the far north west section of communication network 600 in
(61) It is to be noted here that a cluster's capacity may be limited by the total capacity of a very high capacity long hop link that connects a wireless mesh network cluster to fiber PoP 601 or the core network. For example, consider Seed A that serves as an anchor node for the wireless mesh network's first cluster and connects the first wireless mesh network cluster to the fiber PoP via very high capacity long hop link 601-1. This first wireless mesh network cluster's maximum capacity may be limited to the maximum capacity of the ptp/ptmp very high capacity long hop link 601-1.
(62) It is also to be noted here that Seed A that serves as an anchor node may aggregate multiple ptp/ptmp long and short hop links of the wireless mesh network cluster. Hence the total network traffic carried by Seed A from the first cluster to the fiber PoP 601 via ptp/ptmp very high capacity long hop link 601-1 is limited to the total sum of the capacities of all the long and short hop links that terminate at Seed A. Hence the maximum traffic that can flow between a wireless mesh network cluster and the core network may be defined by the minimum of the capacity of a very high capacity long hop link and the sum capacity of all the long and short hop links that terminate at an anchor node (e.g., MIN(Capacity of Very High Capacity Long Hop Link, SUM(Capacities of Short and Long Links terminating at anchor/seed node))).
(63) Referring to
(64) In
(65) Generally speaking, the links AF, BC and DE help in increasing the reliability of the network by providing alternate paths on network 700 for data packets to travel from a source to a destination. In addition, the links AF, BC and DE may help in balancing the load between adjacent wireless mesh network clusters they connect. Hence in an example scenario that involves high load in the first cluster of wireless mesh network of the communication network 700 where a very high capacity long hop link or long/short hop links terminating at Seed A node get congested, data traffic can be re-routed through another cluster (e.g., the sixth wireless mesh network cluster) and very high capacity long hop link 601-6 via link AF that connects the first and sixth wireless mesh network clusters of communication network 700.
(66) Similarly, the 2nd and 3rd wireless mesh network clusters can use link BC for traffic load balancing and increasing reliability of their respective clusters, and the 4th and 5th wireless mesh network clusters can use link DE for traffic load balancing and increasing reliability of their respective clusters. However, based on the discussion above with respect to
(67) Referring to
(68) In other embodiments, degradation can occur due to other reasons that were explained in the context of
(69) During normal network operations, very high capacity very long hop link 601-5E provides additional capacity to the wireless mesh network clusters. For example, in
(70) In
(71) Generally speaking, the presence of very high capacity very long hop links (e.g., very high capacity very long hop link 601-5E) can help reduce the latency for nodes in a wireless mesh network that are at far distance from fiber PoP 601 and data packets from such nodes are required to go through multiple hops even in the presence of long hop links. For example, in case of node 1000, which originally required a minimum of 7 long hops for data packets from node 1000 to fiber PoP 601 as described above, node 1000 in communication network 800 may now require only a single hop via very high capacity very long hop link 601-5E to reach fiber PoP 601. Similarly, the presence of very high capacity very long hop link 601-5E helps reduce the latency or packet delay of nodes in the wireless mesh network that are close neighbors of the node 1000.
(72) In some embodiments, wireless mesh network of communication network 800 of
(73) In the second phase, as shown in
(74) In
(75) In yet another aspect of the present disclosure, a wireless mesh network may be constructed with one or more of (1) seed nodes, (2) type A nodes, (3) adjacent type B nodes, or (4) non-adjacent type B nodes.
(76) To illustrate,
(77) As further shown in
(78) Communication network 1000 of
(79) In practice, the wireless mesh network communication equipment (e.g., antennas, RF and digital circuitry, routers, switches, etc.) deployed on type A customer nodes and seed home nodes are typically powered using the same power source that provides power to a home hosting a wireless mesh network node. Moreover, there may be a backup power supply that can provide power for some time (usually 1˜2 hours) in an event of a power outage to the home hosting a wireless mesh network node. However, in an event of a power outage that lasts for an extended period of time beyond the backup power supply run time, the wireless mesh network equipment will shut down. This can impact not only the wireless mesh communication node with the power outage but also other wireless mesh communication network nodes (e.g., type A customer nodes) that have data pass through the wireless mesh communication node impacted by the power outage. For example, in
(80) Referring to
(81) Accordingly, in one embodiment, a wireless mesh network operator can provide internet data services to customers of type B nodes at subsidized rates. In another embodiment, a wireless mesh network operator can provide internet data services to type B node customers at regular rates. Moreover, via the wired link that connects a type B node to wireless mesh communication network equipment at a type A or a seed node, the type B node can also serve as an alternate source to power the wireless mesh communication network equipment hosted by a type A or seed node site. For example, a type B node customer located above the Seed 1 node site is shown in
(82) In one embodiment, as shown in
(83) In accordance with the present disclosure, building a wireless mesh network may involve various phases to plan and construct the wireless mesh network. For instance, in one example implementation, building a wireless mesh network may involve a pre-marketing phase that may include various subphases to generate leads for potential locations of customers that expressed interest in subscribing to an internet service for the disclosed wireless mesh network. The subphases may involve social media/online marketing, radio/television-based marketing, and/or mailer-based marketing, among other possible marketing approaches.
(84) Based on the leads for potential locations of customers, an area of interest is identified that is used during a geo specific marketing and sales phase, which may involve door-to-door marketing and sales and a door-to-door marketing and sales agent accessing a computing device to upload potential customer information that is provided to a network planning engine. The network planning engine may then select a subset of locations of customers based on various criteria for wireless mesh network installation and deployment. Building a wireless mesh network may involve various other phases to plan and construct a wireless mesh network as well.
(85) As one specific example to illustrate,
(86) For purposes of illustration only, the example blocks shown in
(87) At a high level, block 1201 represents different marketing approaches such as door-to-door marketing and sales (and possibly some pre-marketing approaches noted above, such as social media/online marketing, radio/television-based marketing, and/or mailer-based marketing, etc.) within a certain area of interest (AOI) defined on the basis of multiple factors, which may include the availability of a building with fiber connectivity at a reasonable cost, the level of vegetation in the area, population density, demographics, and/or average annual household income, among other factors. Based on the marketing phase 1201, a pool of potential customers is created at block 1202 which is then fed to network planning engine 1203, where based on certain criteria, a subset of customer locations from 1202 is selected and forwarded to wireless mesh network installation and deployment phase 1204 for the construction of a wireless mesh communication network. Block 1204 may also be referred to as Phase 1. Based on this phase, subsequently in Phase 2A, communications equipment belonging to a different technology type at customer nodes constructed during phase 1 may be deployed, and a different tier of a wireless communication network may be built that can serve other pool of potential customers created at block 1202, which are not picked as wireless mesh network nodes in phase 1 using a different technology tier. In addition, opportunistically in phase 2B, certain potential customers from block 1202 which are not picked in phase 1 and 2A and are suitable for type B customer nodes can be selected to become ancillary wired customer nodes or type B nodes. These ancillary nodes or type B nodes are required to be in close proximity of the seed or type A nodes, so that a wired link can be built between these ancillary nodes and the seed or type A node without too much complexity and cost.
(88) In a preferred embodiment, a type B node is built on a potential customer location that is adjacent to an existing seed or type A home. This way, ancillary wired customer node or type B node gets high speed internet service without requirement for the mmWave based wireless mesh equipment and at the same time the type A or seed node gets an alternate source for power supply from an ancillary wired customer node.
(89) In one embodiment, phase 2A of
(90) In another embodiment, phase 2B of

(95) In still another aspect of the present disclosure, the disclosed systems and methods may involve a private utility or service provider other than a high-speed internet data service provider who has customers (for example single family home security/automation or solar energy customer) in a certain market or neighborhood and plan to offer high speed internet data services to that market or neighborhood by taking advantage of the respective locations of existing customers and using the existing customers as anchor homes for building wireless mesh network nodes.

(98) The process of building a wireless mesh network for high speed internet service in one embodiment may start with identifying potential wireless mesh nodes on existing service customer homes that sign up for a high speed wireless internet data service from their existing private utility or service provider, and allowing the existing private utility or service provider to deploy and install wireless mesh network equipment including ptp/ptmp millimeter wave hardware, antennas, cellular technology based small cells, cables and other associated equipment on their property and/or giving roof access rights. These existing customers can be approached through door-to-door marketing/sales and/or through existing communication channels between the private utility or service provider and their customers. Hence, the private utility or service provider may approach its existing customers represented by black rectangles in
(99) Next step in building a wireless mesh network node may involve performing a line-of-sight analysis on a subset (including a super subset) of the existing customer locations.
(100) Referring to
(101) In one embodiment, none of the existing customer site wireless mesh nodes require an intermediary node to connect them to their nearest or suitable neighbor wireless mesh node as all existing customer wireless mesh nodes exhibit direct line-of-sight with their nearest or suitable neighbors. In another embodiment, all of the existing customer wireless mesh nodes may require an intermediary node to connect them to their nearest or suitable neighbor wireless mesh node as all existing customer wireless mesh nodes may exhibit non-line-of-sight with their nearest or suitable neighbors. In yet another embodiment, wireless mesh network nodes of the private utility or service provider can have some existing customer wireless mesh nodes with direct line-of-sight to their nearest or suitable neighbor along with some existing customer wireless mesh nodes with non-line-of-sight to their nearest neighbor thus requiring intermediary mesh nodes to connect them to their nearest or suitable existing customer. In one embodiment, in case of line-of-sight path/connectivity between existing customer wireless mesh nodes, ptp/ptmp mmWave frequency narrow beam width links may be established between existing customer nodes of the service provider if certain criteria including but not limited to received signal strength, line-of-sight with certain minimum number of neighbor homes, etc. is met.
(102) In case of no line-of-sight connectivity between existing customer nodes of the private utility or service provider, planning for an intermediary node is performed by the wireless mesh network planner or operator. In one embodiment, planning for intermediary node may involve targeted marketing including door-to-door marketing and online/social media/influencer-based marketing to those potential intermediary customer homes that can help in establishing a line-of-sight ptp/ptmp links-based path between existing customer wireless mesh network nodes. Next, some of those intermediary home locations are acquired by sale of high speed internet service to those intermediary customers that sign up for high speed internet service either as an independent service or as a bundled service where in addition to high speed internet service, a utility or service is provided to the customer in exchange for allowing the private utility or service provider to deploy and install wireless mesh network equipment including ptp/ptmp millimeter wave hardware, antennas, cellular technology based small cells, cables and other associated equipment on their property and/or giving roof access rights to the provider. This is followed by building wireless mesh nodes on the newly acquired intermediary customer sites. Next, connectivity between the new intermediary nodes and existing customer nodes is established by adding ptp/ptmp links between these nodes.

(104) In turn, a wireless mesh network may be completed by adding high capacity links to seed node sites (e.g., Seed 1 and Seed 2) in order to connect the nodes to a fiber PoP site represented as fiber PoP 1701 in
(105) Referring to
(106) At block 1801, one embodiment may involve performing line-of-sight analysis based on existing customer nodes. In this phase, line of sight analysis is performed to determine which customer nodes have direct line-of-sight path with their nearest or suitable neighbor node and which customer nodes require intermediary nodes to establish connectivity with the nearest or suitable wireless mesh network node.
(107) Based on the above phase, at block 1802, wireless mesh network equipment may be deployed and installed at existing customer nodes and at block 1803, ptp/ptmp links may be established that connect the two existing customer wireless mesh nodes through a high-speed narrow beam width link.
(108) In one embodiment, parallel to block 1802 and 1803, at block 1804, the disclosed process may involve planning for intermediary sites, which may involve targeted door-to-door and online/social media/influencer-based marketing model to get new customers signed up for high speed internet service and allowing the wireless mesh operator to install and deploy wireless mesh network equipment on their premises along with roof access rights. At block 1805, based on the acquired intermediary customer sites, new wireless mesh nodes are built.
(109) In turn, at block 1806, ptp/ptmp links are established between two intermediary new customer nodes and between a new intermediary customer node and an existing customer wireless mesh network node. At block 1807, end to end connectivity may be provided by adding high capacity links via a seed site to a fiber PoP site.

(111) It is also to be noted that throughout this current disclosure, and specifically in the context of
(112) In still another aspect of the present disclosure, all nodes of the wireless mesh network can be equipped with at least one point-to-multipoint radio that is capable of establishing bi-directional links with multiple neighboring wireless mesh nodes, and possibly other point-to-point or point-to-multipoint nodes. These point-to-multipoint links use time division multiplexing (TDD) to create bi-directional links. For example, assume a ptmp link between node A and node B that is configured for 50% Downlink and 50% Uplink transmission duty cycle. This means that during 50% Downlink time period, node A will be in listening mode and node B will be in transmitting mode. Hence, node B will be uploading, and node A will be downloading. In the next 50% Uplink transmission time period, roles of the nodes A and B will be flipped and during that 50% uplink duty cycle, such that node A will be in the transmitting mode and node B will be in the listening mode.
(113) In the foregoing example, bi-directional links may be symmetric and the data bandwidth in both directions may be the same. However, it should be understood that the transmission duty cycle can be made asymmetric by dedicating more time to downlink or uplink based on the traffic flow requirements.
(114) In a mesh network comprising point-to-multipoint nodes, certain paths along the mesh network may be critical if they carry backhaul data for a large number of customers. Such links can be made more robust by changing the transmission duty cycle of the bi-directional link. For example, assuming that node A is connected to node B, node C, node D and node E and the bi-directional link between node A and node B carries critical backhaul/signaling or other higher priority data of the wireless mesh network and other links including bi-directional links between node A and node C, between node A and node D, between node A and node E just carry regular end user traffic, then the directional link between node A and node B can be made robust by changing the transmission duty cycle of point-to-multipoint radios.
(115) In one embodiment, the transmission duty cycle for the node A can be made such that it performs uplink transmission with node B for 35% of the time, downlink transmission with node B for 35% of the time, uplink transmission with node C, D and E for 5% of the time and downlink transmission with node C, D and E for 5% of the time, Other neighboring nodes of the node A including node B, C, D and E can then adjust their duty cycle to synchronize their transmitting and receiving time intervals accordingly. This will allow to shape the bandwidth of the critical links of the wireless mesh network based on the traffic flow requirement and these changes can be performed dynamically. It should be noted that these duty cycles in some embodiments can be instantaneous duty cycles and in other embodiments, represent average duty cycles over a certain time window with multiple transitions between uplink and downlink.
