摘要： Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).

摘要： A system and method for sharing antennas of a wireless communication device is provided. The wireless communication device leverages cellular antennas to improve data throughput by creating a multiple-in, multiple out (MIMO) operation for a wireless local area network (WLAN) connection. Antenna resources are dynamically allocated between the cellular antennas and the wireless antenna to provide improved throughput.
