EnGenius NMP / EMP-8602S (600 mW)
EMP-8602S or NMP-8602S is a mini-PCI type III B high-power card supporting dual-band (2.4GHz & 5GHz) radio operation. It provides a high-speed wireless connection with a data rate up to 54Mbps. The small form factor, light weight & lower power consumption design can easily integrate into a wide range of AP/Bridge devices.
The 802.11g standard is backwards compatible with 802.11b standard. You do not need to change your entire network to maintain connectivity. You may sacrifice some 802.11g speed when you mix 802.11b and 802.11g devices, but you will not lose the ability to communicate with your 802.11b network.
For more security, the mini-PCI can support 802.1x, WPA and WPA2 (IEEE 802.11i), and offers the highest power in its class to improve distance and performance
