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.
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 …show more content…
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 compatibility to existing 802.11x, automatic detection of legacy networks, training for wider channels are already in the plan for further discussion and execution. And the next step would be definition on the structure of packet, PHY (physical layer) and MAC (media access control), QOS (Quality of Service), Error Correction technique and many more with final intention to have an ultra high wireless bandwidth protocol suitable for various …show more content…
The coming upgrade may deliver speeds of up to 1 gigabit per second by improving on the effeciency of existing technology, according to Electronista.
Don't expect a revolution or a vast change in the way you use wireless. The IEEE 802.11ac standard, set to be in draft form by 2011, will mainly work with the current technology powering 802.11a. The new standard will continue to work on the 5.0Ghz band, but will provide larger channels for data throughput. Whereas current technology uses 20Mhz-wide channels, 802.11ac will be using either 40Mhz or 80Mhz-wide (and possibly 160Mhz) channels to deliver data. It's the equivalent of adding a wide-mouth tab to your beer can, so your files will be able to flow more freely on your home network come 2012.
Of course, none of these specs are standardized as yet and they may be drastically change in the next few years. On top of that, a fatter pipe for wireless data throughput does not increase our actual internet connection
