Fixed Wireless Access (FWA) is a wireless subscriber connection that offers itself as a wireless alternative to a wired subscriber connection in the access area. With FWA technology, which is suitable for private households and SMEs (small and medium-sized enterprises), the last mile to the subscriber
is bridged by radio technology. Long Term Evolution (LTE) mobile networks of the 4th generation (4G), but above all also those of the 5th generation (5G), are suitable for radio transmission in the connection area. In the case of an FWA connection, a radio link takes over the function of cable-based transmission via copper cable with DSL technology or via optical fibre. When using 5G, the transmission capacity can be significantly increased compared to 4G and the latency reduced. Since subscribers must share the 5G wireless link, an FWA wireless link cannot replace Fiber To The Home
(FTTH).A Fixed Wireless Access can be implemented as a point-to-point link or a point-to-multipoint link and connects the subscriber line to a base station. The transmission works with Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), carrier aggregation and MIMO technology and can realize data rates in the gigabit range. It is transmitted from a transmitter to stationary receiving equipment in houses or buildings. Reception is via an antenna
and an RF modem. Thebroadband FWA version is Broadband Fixed Wireless Access
(BFWA). An alternative to cellular networks is Fixed Wireless Access (FWA), which bridges the last mile via a point-to-point link in the 60 GHz band. This application, which can transmit data rates in the gigabit range, is Wireless to the Home (WTTH) and is being tested by several providers. Another scenario is Wireless to the Building (WTTB), with the difference that the in-building distribution is achieved by a WLAN or wired network.
