What is the difference between wireless N and wireless G?

The

device that operates wireless networks is made to be compatible with one or more wireless specifications, so products from different manufacturers can be interoperable. Wireless-N is a newer specification than wireless G and has some key advantages over the older protocol. Newer specifications can work on the wider frequency zone, it is faster and more robust. Wireless N is also referred to as its numeric classification 802.11n, while the predecessor, wireless G is 802.11g. The wireless classification 802.11 and its relevant flavors, which are determined by the end letter, are published by the institute of electronic and electrical engineers (IEEE).

The top speed of the standard wireless network is 54 megabits per second (MBPS), although the real world speeds are somewhat slower. Super-G or Xtreme G, Hybrid 802.11g, boasts 108 Mbps, but it requires proprietary hardware. Standard 54 Mbps is in fact still quite fast when you noThe linen considers the average internet Connectionnasting is limited to 1-5 Mbps. Internet Premium DSL, cable and optical internet can offer speeds between 10-50 Mbps, still as a network capabilities. For average person and business, however, top-end speeds will only be achieved and appreciated when sharing files between local machines.

Wireless-N includes (multiple input, multiple output). Outside, they use multiple antennas that simultaneously transmit and receive several "special streams" of data. As a result, speeds can reach 450 Mbps using three special streams, with 600 Mbps being a theoretical maximum using four special flows. This assumes that each current uses a wide belt of 40 MHz and these specifications apply to the finalized standard 802.11n-2009.

Before IEEE was completed in September 2009, 802.11n developed for several years. Products produced during this period are in compliance StandaRDY wireless n with theoretical speeds of 300 Mbps. Real-world speeds are closer to 130-180 Mbps, although it differs due to different flavors of 802.11n and the eccentricity of compatibility between hardware. The wireless N router can be upgraded to 802.11n-2009 via BIOS flash depending on the manufacturer.

Wireless-N is not backward compatible with wireless g. It works on the 2.4 GHz band, while the "TRUE" 802.11N uses 5 GHz belt, although it can operate at 2.4 GHz with hit for performance. The switch is desirable due to the number of gadgets acting in the 2.4 GHz band, which can potentially introduce interference. Some examples include microwave furnaces, many types of wireless and mobile phones surrounding the 802.11g networks and Bluetooth® networks.

The router may contain radios for both belts and offer support for 802.11g and 802.11n, but in mixed mode degrades wireless N Performance. In order for the network to fully realize the N-View means must be all KO equipmentMpatible with 802.11n-2009 and operates in 5 GHz band.

Many factors affect the efficient range of broadcasting the wireless network, including network hardware, configuration, building materials in the surrounding structures and topography in the case of outdoor networks. The integrity of the signal also decomposes above the distance. The internal range of the finalized standard 802.11n-2009 can be approximated to 300 feet (91 m) inside and up to 850 feet (259 m) outside, but the results differ. This compared to wireless G at approximately 150 feet (46 m) inside and 300 feet (92 m) outdoors. Extension and other technologies can be used to extend the network range if necessary.

People or businesses that only maintain a wireless network for sharing a standard Internet connection, do not notice a difference between wireless N and wireless G, if unfavorable conditions worsen the wireless G that would not FAC.Tors in the wireless N Network, such as 2.4 GHz. Other reasons for switching would be for a deeper broadcast range orTo share a very fast Internet connection.

those who share wirelessly among local machines can tremendously benefit from upgrading to a wireless network that realizes much faster transfer rates, improve productivity and save time. The router and all network cards or adapters should be in accordance with the 802.11n-2009-or-or-or-you-the-art specification to ensure the best results and investment for the future.
