802.11b
802.11g
802.11n
802.11a works at the frequency of five GHz. Most of the wi-fi alerts use the 2.4GHz band, so there's a whole lot extra opportunity for lowering the energy of the signal, due to the fact interference with different alerts that ...
... works at the identical frequency. Speed utilized by this fashionable is 54Mbps and it's miles nearly five instances extra than the velocity of 802.11b fashionable. 802.11b works at the frequency of 2.four GHz and with the most velocity of eleven Mbps. This frequency of 2.four GHz is an unregulated frequency and the carriers do now no longer should pay the license for it. The variety withinside the indoor surroundings is set 35 meters (117 feet), and a hundred meters (333 feet) in outside surroundings. 802.11g works at the frequency of 2.four GHz, with the most velocity of 54Mbps.

Speed is typically 150Mbps, however, a number of the wi-fi routers should paintings even on three hundred Mbps. The variety is 6 instances father evaluating to 802.11g. Since it's miles nevertheless now no longer standardized, a majority of these values of velocity and variety you have to take for granted. If you're shopping for a new wi-fi gadget, it is ideal to take the only which help n.

A broadband connection is supplied through fiber optics, DSL, Ethernet, or cable modem. Every wi-fi broadband router is a Wireless get entry to factor (connects wi-fi gadgets like computer systems and PDA-s to a stressed-out community) with broadband get entry to and a router (a tool that ahead packets among pc networks) on the identical time. What is a WiFi card? It connects gadgets to the wi-fi LAN community or the WiFi community. On the internet, you can discover the opportunity names WiFi card and wi-fi community card. Wireless community playing cards help one or greater 802.11a, 802.11b, 802.11g, or 802.11n WiFi requirements..
