BEYOND 802.11N
So what's next on the wireless horizon? A new standard, known as Very High Throughput (VHT), will feature data rates of between 4Gbps and 7Gbps, nearly five times the rate of 802.11n, and will operate on the 60GHz frequency band. As such, the new standard will likely have limited range and will be best suited to peer-to-peer applications such as streaming video from one device to another or moving very large chunks of data in a matter of seconds. Definitions

Latency : In a network, latency, a synonym for delay, is an expression of how much time it takes for a packet of data to get from one designated point to another. In some usages (for example, AT&T), latency is measured by sending a packet that is returned to the sender and the round-trip time is considered the latency. Throughput or network throughput is the average rate of successful message delivery over a communication channel. Multiple Input Multiple Output (MIMO)

* Will 802.11ac Gigabit WiFi be the death of Ethernet?
* 802.11ac Standard Will Bring Gigabit Speeds to WiFi
* 802.11ac (theoretically) will support speeds from 600 Mbps to 1Gbps. It will utilize <6 GHz frequencies. * While consumer PC products have just started to migrate to much higher bandwidth 802.11n, now the work on next generation WLAN standard definition is already in progress. Named as 802.11ac, it is expect to boost the network bandwidth up to 1Gbps, on par with what can be achieved by wired networking in today’s PC world. * The design goal has been focused much on how to scale up its bandwidth significantly. If you aware, 802.11n has able to push its data rate up to 300Mbps utilizing its MIMO technology, which is already few times higher than conventional 802.11b/g standard, but it will never enough to cater for much higher resolution media streaming in digital home. No information on what kind of technology it will be based on, but some details such as backward...
