Abstract: 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).
Abstract translation: 实施例提供WiFi和LTE定制的收发射频（RF）滤波技术和配置，以实现在接近操作的WiFi和LTE收发器之间的共存。 具体地，实施例提供了滤除技术来拒绝从WiFi到WiFi的发射，反之亦然。 滤波技术消除了LTE和WiFi天线之间的额外隔离（约50 dB）的需要，这超出了实际可实现的范围。 可以根据WiFi和LTE收发器（例如，固定CPE，便携式路由器，带有束缚的智能电话）的不同用例来定制实施例。
