Some other specifications
The Realtek RTL8187SE is a low-profile highly integrated cost-effective Single-Chip Wireless LAN network interface controller that integrates a Wireless LAN MAC, a baseband processor, and 2.4GHz RF onto one chip. It provides a PCI Express bus controller, and full compliance with IEEE 802.11 and IEEE 802.11b/g specifications. It also complies with WMM, 802.11e, and CCX specifications.
To reduce protocol overhead, the RTL8187SE supports Short InterFrame Space (SIFS) burst mode to send packets back-to-back. A protection mechanism prevents collisions among 802.11b nodes.
