Methods, systems, and a non-transitory computer-readable medium that provide a sanctuary antenna for mitigating FDD carrier degradation during TDD antenna sharing are provided. The method begins with determining that the carrier degradation will occur during at least one FDD receive signal slot in a FDD frequency band on at least one antenna of the TDD frequency band based on the at least one FDD receive signal slot coinciding with at least one scheduled TDD transmit slot. Then, based on the determining, switching at least one scheduled FDD receive signal slot from the at least one antenna of the TDD frequency band to a sanctuary antenna occurs. The sanctuary antenna is used for a duration of at least one sounding reference signal (SRS) symbol.

Spatial compute devices form an ad-hoc communication network that comprises includes point-to-point wireless links between the spatial compute devices. The spatial compute devices exchange application data for a user application over the ad-hoc communication network. The spatial compute devices indicate their ad-hoc communication network, user application, and application users to an application server system. A new spatial compute device detects the ad-hoc communication network and queries the application server system. The application server system responds to the new device with the application users that are currently using the user application over the ad-hoc communication network. The new device presents to a user the application users that are currently using the user application over the ad-hoc network, and in response, receives a user selection of the user application. The new device wirelessly exchanges new application data for the user application with the other application users over the ad-hoc communication network.

A conversation is handed over between an unlicensed data network and a cellular network. Voice conversations and/or video conversations may be seamlessly transitioned between cellular networks and unlicensed data networks (e.g., Wi-Fi), with a small transition time (e.g., less than a couple of seconds). The handover may occur from the unlicensed data network to the cellular network or from the cellular network to the unlicensed data network. During the transition between networks, cached registration data is accessed to speed up the authentication of the computing device switching networks. In some configurations, a user may specify preferences for switching between the unlicensed data and cellular networks. For instance, a user may specify a preference to use Wi-Fi networks before cellular networks or to use cellular networks before using Wi-Fi networks.
