802.11g is the third modulation standard for wireless LANs.It works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s.Using the CSMA/CA transmission scheme, 31.4 Mbit/s [9] is the maximum net throughput possible for packets of 1500 bytes in size and a 54 Mbit/s wireless rate (identical to 802.11a core, except for some additional legacy overhead for ...
WRT54GX comes with SRX (Speed and Range eXpansion), which uses "True MIMO" technology.It has three antennas and was once marketed as a "Pre-N" router, with eight times the speed and three times the range over standard 802.11g routers.
Atheros has also adapted this technology to their 802.11a/g chipsets, marketing it as Super AG. Super G is one of several competing incompatible proprietary extension approaches that were developed to increase performance of 802.11g wireless devices, such as Xpress from Broadcom, MIMO-based extensions from Airgo Networks, and Nitro from Conexant.
But in long-range Wi-Fi, special technologies are used to get the most out of a Wi-Fi connection. The 802.11-2007 standard adds 10 MHz and 5 MHz OFDM modes to the 802.11a standard, and extend the time of cyclic prefix protection from 0.8 μs to 3.2 μs, quadrupling the multipath distortion protection. Some commonly available 802.11a/g chipsets ...
This Linksys WRT54GS, a combined router and Wi‑Fi access point, operates using the 802.11g standard in the 2.4 GHz ISM band using signalling rates up to 54 Mbit/s. IEEE 802.11 Wi-fi networks are the most widely used wireless networks in the world, connecting devices like laptops (left) to the internet through a wireless router (right).
Linksys "WAP54G" 802.11g wireless router Embedded RouterBoard 112, widely used by wireless Internet service providers (WISPs) across the world, with U.FL-RSMA pigtail and R52 mini PCI Wi-Fi card An AP connects directly to a wired local [ 3 ] area network , typically Ethernet , and the AP then provides wireless connections using wireless LAN ...
An early example of a wireless router The internal components of a wireless router. A wireless router or Wi-Fi router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network.
However, many 2.4 GHz 802.11b and 802.11g access-points default to the same channel on initial startup, contributing to congestion on certain channels. Wi-Fi pollution, or an excessive number of access points in the area, can prevent access and interfere with other devices' use of other access points as well as with decreased signal-to-noise ...
