In a wireless docking system a host (100) is arranged for docking a dockee (120) and relaying data packets from the dockee to an audio/video peripheral (110,111,112). The host is arranged for using a first host interne protocol [IP] address as address for the host for the wireless communication while docking the dockee, and using a second host IP address as address for the host for the wireless communication for setting up a direct connection to the audio/video peripheral, while the host operates as an audio/video data source towards the peripheral, and providing the second host IP address to the dockee. The dockee is arranged for using the second host IP address as source IP address for the dockee for exchanging data packets with the audio/video peripheral while transferring the data packets via the host. The audio/video peripheral can keep on using the same destination IP address and is not aware of actually communicating with the dockee.

An network of wireless RF repeaters includes a first communication device and a second communication device. The first communication device obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. A frequency of each of the plurality of RF signals is upconverted to a different frequency, which introduces a phase noise in the plurality of RF signals. The plurality of RF signals corresponding to different communication protocols are merged into a mmWave RF signal of a specified frequency and a defined pilot tone is inserted into the mmWave RF signal. The second communication device captures the mmWave RF signal having the defined pilot tone over-the-air. At least one RF signal is down converted to a source frequency and the phase noise in the one extracted RF signal is reduced concurrently based on a reference of the defined pilot tone.

A plurality of radio frequency (RF) signals corresponding to different communication protocols is obtained via the plurality of different type of wireless networks. The obtained plurality of RF signals corresponding to different communication protocols are merged into a mmWave RF signal of a specified frequency. The mmWave RF signal of the specified frequency is transmitted to a second communication device.

A search and rescue (from hereon, SAR) optimization/prevention system is set forth, for ensuring the safety and connectivity of people in locations such as but not limited to national parks, hiking trails, mountains, lakes, rivers, forests, and other areas that do not receive (or receive inconsistently) reliable cellular, satellite, or GPS network connectivity. The mesh network system comprises wearable devices used by the person being located, and transceivers responsible for getting a signal from the user to a responder via the bouncing of a signal. Once a signal is received at a designated transceiver, the system may output information about the at least approximate location and condition of the user that transmitted the signal, including the approximate location, time of distress, and other pertinent data, based on information carried in the signal.

An operation method of a relay node may include: receiving, from a first communication node, first data composed of n bits; receiving, from a second communication node, second data composed of m bits; in response to determining that n is greater than m, generating first T-data of m bits excluding (n−m) bits from the n-bits of the first data and first R-data of (n−m) bits; generating third data by performing a network coding operation on the first T-data and the second data; transmitting the third data to the first communication node; and transmitting the third data and the first R-data to the second communication node.

A two-way wireless relay transmission method suitable for multiple relay nodes proposes a transmission solution based on a Decode-and-Forward (DF) technology and Network Coding (Network Coding, NC) technology suitable for a two-way wireless relay network.
