UniFi UF1050 is a single-chip Wi-Fi solution capable of both IEEE 802.11b and g operation, and highly optimised for embedded applications. Its WL CSP package makes it ideal for embedded system developers seeking compact designs. UF1050 integrates a high-performance 2.4 GHz radio, baseband processor and media access controller (MAC) and other radio components onto a monolithic die, providing an extreme level of chip integration.  This reduces the size, cost and power consumption of a wireless LAN solution, opening up mass market volume embedded solutions in the consumer market. An exceptional degree of 'coexistence' with other radios is designed in, including flexible Bluetooth/Wi-Fi collision decision logic (with uniquely high, and robust performance if CSR Bluetooth IC is used). The RF front-end includes the CCK modem (used for 802.11b) and the OFDM modem (used for 802.11g). Dual RISC processors and hardware accelerators for 802.11 MAC functions and encryption are provided, delivering full 54Mbps operation. The device provides full QoS for 802.11e and security support for 802.11i.
