EMP-8601+ is a mini-PCI type III B high-power card supporting dual-band (2.4GHz & 5.0GHz) radio operation. It provides high-speed wireless connection with data rates up to 108Mbps and extend range with high output power. The 802.11g standard is backwards compatible with 802.11b products. This means that 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 when you incorporate the 802.11g standard into your 802.11b network
