A wireless testing system is provided that tests Wi-Fi signal strength of devices of a local network to determine distribution of network devices within the local network. In particular, one or more Wi-Fi-based devices may be located within or near a premises in which a wireless network is present. The devices are configured to automatically connect to a particular test broadcast signal from a modem and provide signal strength data. An application may log into or otherwise access the information obtained by the modem concerning the Wi-Fi signal strength of the wireless devices. The application may analyze the Wi-Fi signal strength information and may execute a recommendation engine to provide one or more recommendations/directions for installing components of the wireless network, such as wireless devices, modems, etc. to improve the coverage of the wireless network and provide a more robust wireless experience for devices within the wireless network.

A method for controlling a network connection includes: detecting a type of a 5G resident network of the mobile terminal; determining whether the mobile terminal meets a data flow interruption condition; and performing an operation for making the mobile terminal change a 5G link mode according to the type of the 5G resident network, when the mobile terminal meets the data flow interruption condition. In the present disclosure, the operation for making the mobile terminal change the 5G link mode is performed according to the type of the 5G resident network, and when the mobile terminal meets the data flow interruption condition, the terminal can be changed from the current link to another link, which is a link to a different base station or a different network, thereby increasing the possibility of solving the problem of data flow interruption.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for reliable communication between a source device, and two or more sink devices. In one aspect, a sink device closest in proximity to the source device can establish a wireless data transfer with the source device. In another aspect, the sink device having the more favorable radio channel conditions can establish a wireless data transfer with the source device. In some aspects, the sink devices can forward audio data received from the source device over a secondary communication link. The audio data can be forwarded to the other sink device automatically, or upon request from the other sink device. The secondary communication link can be implemented as a magnetic communication link, or as a Bluetooth communication link.

A BS generates a test configuration of wireless signals for testing the BS for compliance with one or more criteria. The BS supports NB-IoT signals and NR signals, and is configured to support multiple carriers and to support operation within an RF bandwidth. The test configuration includes: a NB-IoT test signal placed as an outermost carrier at one or both edges of the RF bandwidth but not within a new radio minimum guard band, wherein for NB-IoT operation in new radio in-band, the NB-IoT test signal is placed as an outermost resource block within a NR transmission bandwidth configuration plus 15 kHz at an edge but not within the NR minimum guard band; and further test signal(s), comprising NR signals, in the RF bandwidth. The BS transmits the test configuration of wireless signals.
