1.0 Scope
1.1 Document
This document is to specify the product requirements for 802.11n Draft 2.0 Mini PCI. This mPCI
is based on Ralink chipset that complied with complied with IEEE 802.11n Draft 2.0, and it is also
backward complied with IEEE 802.11a standard from 5.15~5.850GHz(upon every contries to use
different frequencies) wideband and IEEE 802.11b/g standard from 2.4-2.4835GHz. It can be used
to provide up to 54Mbps for IEEE 802.11a and IEEE 802.11g , 11Mbps for IEEE 802.11b and
300Mbps for IEEE 802.11n to connect your wireless LAN.
