1. Introduction. The new Wi-Fi AC technology
2- Labels 802.11AC and 5Ghz in the new wireless devices.
Many users ask what 802.11ac means, also if they need this new technology to improve the WiFi browsing experience in the home or office.
As of 2014, you will have verified that when you install a new fiber optic internet line you will also be installed with a Wi-Fi router with dual band. Currently Vodafone, Movistar and Jazztel dual band routers incorporate AC technology in addition to the classic Wi-Fi N / G / B. These new routers maintain the 802.11 standard but they differ in the letter that follows after this number, the old ones had the denomination 802.11n and the new ones the 802.11ac.
The classic router with WIFI 802.11n technology, is still a fully usable system as they reach transfer rates of up to 450 Mbps. This speed is enough for daily use, but you can fall short when watching TV on the Internet or for some online games.
The new 802.11ac technology was approved by the IEEE for sale to the consumer in 2014. It is capable of transmitting incredible speeds of 1.3Gbits per second. Thus, the average transfer rate of an AC router reaches twice as much as with the more usual Wi-Fi N.
3- How is this high Wi-Fi speed achieved through the AC system?
The explanation is that the new Wi-FI AC to achieve this type of performance emits in the 5 GHz band and it is helped with up to eight spatial flows (MIMO). Using the 5Ghz frequency that has a much longer wavelength, signal loss is avoided. In addition, the 2.4Ghz band is currently completely saturated, causing very frequent interference in urban areas, while the 5Ghz band is practically still free.
The most modern Wi-Fi N systems have recently incorporated 802.11n MIMO technology that supports four spatial flows (4 × 4 MIMO) and a channel width of 40MHz. But 802.11ac can use eight spatial streams and has channels up to 80MHz wide – which can then be combined to make 160MHz channels.
4- Is it really necessary to pass all my devices to 802.11ac technology?
The reflected answer says that not yet. The Wi-Fi N system has still many years of travel. If we take into account that still many fiber internet lines do not reach 200MBps, we will understand that our Wi-Fi N receivers are enough to navigate at maximum speed.
In addition, the new routers that are installed support the Dual Band or dual band system, which means that they emit both 2.4Ghz and 5Ghz, so our N technology USB Wi-Fi phones, tablet and antennas can always be connected to the new AC router. 802.11ac, is fully backwards compatible, so you can now buy an 802.11ac router and it should work perfectly with your older 802.11n and 802.11g Wi-Fi devices.
You can continue using and buying USB Wi-Fi N adapters for years for daily internet use with speeds of up to 300 Mbps. But for demanding jobs, online video games and online television, you can already go to Wi-Fi AC with USB adapters and dual band router at really affordable prices, especially if you are going to enjoy the new fiber optic lines at high speed.
It is also a good idea to use the 5Ghz frequency to establish long-distance Wi-Fi connections, without interference with the new Ubiquiti CPEs at 5Ghz as a LocoM5 nanostation. Ubiquiti outdoor router 5GHz wifi WISP CPE Nanostation locoM5. Facing two of these devices with Ubiquiti AirMax technology, in open spaces you can get a stable Wi-Fi connection over 5km without problems, try it.
