According to a published draft information on 802.16 standards, the IEEE is currently working on a new wireless standard called 802.16m. The new standard is still more than a year or two away, but according to IEEE documents, the group hopes that 802.16m will be able to deliver 1Gbps transfer rates over the air. In fact, 802.16m is "required" to meet downstream speeds of up to 1Gbps in "nomadic" mode, or high efficiency/strong signal mode. The standard also has a "high mobility" mode which allows for 100Mbps rates. What gives 802.16m the capability to reach such high speeds is its use of multiple-input/multiple-output (MIMO) technology. MIMO is currently used in a host of 802.11g and 802.11n routers and access points currently available on the market today to speed things up. 54Mbps routers that use MIMO are capable of reaching theoretical speeds up to 108Mbit.sec.
