REALTEK RTL8187B MINI-PCI-e Wireless WiFi LAN Card 802.11b/g RTL8187 New by REALTEK
Condition: Brand new
The 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.

The RTL8187B supports fast receiver Automatic Gain Control (AGC) and antenna diversity functions, and an adaptive transmit power control function to obtain better performance in the analog portions of the transceiver. It also has on-chip digital-to-analog converters and analog-to-digital converters for analog I and Q inputs and outputs, transmit TSSI and receiver RSSI inputs, and transmit and receiver AGC outputs.
The RTL8187B keeps network maintenance costs low and eliminates usage barriers. The RTL8187B is highly integrated and requires no 'glue' logic or external memory.
Note: This module is compatible with ALL laptops that have a mini PCI-E internal slot. not for IBM, and not for HP machines
