Realtek RTL8187B is a low-profile highly integrated cost-effective Wireless LAN USB 2.0 network interface controller that integrates a USB 2.0 PHY, SIE (Serial Interface Engine), 8051 MCU, a Wireless LAN MAC, and a Direct Sequence Spread Spectrum/OFDM baseband processor onto one chip. It provides USB high speed (480Mbps), and full speed (12Mbps), and supports 9 endpoints for transfer pipes. To reduce protocol overhead, the RTL8187B supports Short InterFrame Space (SIFS) burst mode to send packets back-to-back. A protection mechanism prevents collisions among 802.11b nodes. The RTL8187B fully complies with IEEE 802.11a/b/g, WMM, 802.11e, and CCX specifications.
