Channel Bonding In WiFi: Rules And Regulations. The second part of this blog series examines the IEEE standards and government regulations that impact channel bonding.

Channel Bonding In WiFi: Rules And Regulations

Channel bonding has become a very useful mechanism for accommodating growing WiFi data capacity requirements. But as I explained in my last blog, the laws of radio frequency physics can make channel bonding challenging to use in practice. In this post, I discuss the impact of IEEE standards and regulatory restrictions on channel bonding, and how this makes the use of channel bonding even more complicated. In the IEEE 802.11a and 802.11g WiFi standards, channel widths were strictly defined as being 20 MHz in size. The number of independent channels varied by country, but most regulatory domains allowed for at least three channels on the 2.4 GHz band (802.11g) and at least five channels on the 5 GHz band (802.11a).

As mentioned in my last blog, the size of the usable frequency band for WiFi per regulatory domain (i.e. country) is fixed. 802.11ac Class Speed Ratings. The end of slow public WiFi? Researchers develop new protocol that boosts WiFi performance by 700% Conferences, airports, cafes – they might offer free WiFi to visitors, but they are often sluggish in their operation because everyone else is hogging the connection.

The end of slow public WiFi? Researchers develop new protocol that boosts WiFi performance by 700%

This issue might become a thing of the past, after a team of engineers at NC State University (NCSU) announced the development of WiFox (via ExtremeTech), a new software protocol that could theoretically be added to existing Internet routers and is capable of boosting WiFi performance by 700 percent. Traditionally, routers offer a single channel of data to users. When the access point receives an increased number of data requests, it becomes harder for it to send back the data it has requested. The access point could be programmed to give all pieces of data a high priority to clear its backlog, but then users have issues submitting new requests. Data backs up, and the router has issues dishing out the necessary information to users. Image Credit: laughingsquid/Flickr.

IEEE 802.11ac. IEEE 802.11ac is a wireless networking standard in the 802.11 family (which is marketed under the brand name Wi-Fi), developed in the IEEE Standards Association process,[1] providing high-throughput wireless local area networks (WLANs) on the 5 GHz band.[1] The standard was developed from 2011 through 2013 and approved in January 2014.[1][2] According to a study, devices with the 802.11ac specification are expected to be common by 2015 with an estimated one billion spread around the world.[3] This specification has expected multi-station WLAN throughput of at least 1 gigabit per second and a single link throughput of at least 500 megabits per second (500 Mbit/s).

IEEE 802.11ac

This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to eight), downlink multi-user MIMO (up to four clients), and high-density modulation (up to 256-QAM).[4][5] New technologies[edit] Mandatory and optional features[edit] Products[edit] News e aggiornamenti TECNO.

Connettività, news. My NEWS pearltreeS. Tecnologia Wireless AC. Il Galaxy S4 supporta lo standard WiFi AC. Ma di cosa si tratta? Il WiFi AC, o meglio l’ ieee 802.11ac, è un nuovo standard wireless introdotto a fine 2012 e che già da quest’anno dovrebbe iniziare a diffondersi con l’arrivo sul mercato di nuovi modelli di router domestici.

Il Galaxy S4 supporta lo standard WiFi AC. Ma di cosa si tratta?

Il Samsung Galaxy S4 è uno dei primi dispositivi del 2013 a supportarlo, proprio come accaduto con i predecessori per altri standard (es. WiFi Direct con il Galaxy S2). I vantaggi rispetto alla precedente tecnologia sono evidenti. Il primo riguarda la velocità massima raggiungibile. Samsung galaxy s4. Smartphone. Cosa c'è da sapere sul protocollo Wi-Fi 802.11ac. News Pubblicato il 2 maggio 2013 | di Redazione PcWorld.it I router wireless 802.11ac promettono velocità fino a livello gigabit e migliori performance per lo streaming video.

Nel corso del 2013 il protocollo 802.11ac è passato dall’essere una tecnologia del futuro alla realtà. Malgrado lo standard sotteso sia ancora in fase di sviluppo, le case produttrici non si sono fatte scappare l’occasione per lanciare un numero crescente di prodotti. Belkin ha annunciato due router, l’AC 1800 DB e l’AC 750, non ancora disponibili in Italia. Il router dedicato al gaming di D-Link (DGL-5500), che inizierà a essere spedito nel corso di questo mese e i cui prezzi non sono ancora definiti, dispone della funzione StreamBoost di Qualcomm che dà priorità nel traffico per i video in streaming e per i giochi, migliorandone sensibilmente le performance.
