802.11

802.11 is a versatile wireless technology that acts as a cable replacement in a standard local area network.

The name 802.11 is derived from the IEEE standard that it represents. 802.11 refers to a family of wireless standards, each differing slightly in the implementation, but achieving the same goal, networking computers without wires.

IEEE 802.11g, has overtaken IEEE 802.11b as the most popular standard. This is commonly called Wireless LAN or Wi-Fi.


Radio Frequency Site Survey
A site survey delivers a comprehensive Wireless LAN Blueprint. This explains how to deploy wireless LAN technologies given your individual networks needs. We provide RF image maps, which illustrate coverage, optimum number and positioning of access points and antennae, cable runs, and more. We also design WLAN schema, wlan security policies,wlan integration and offer unbiased hardware advice.

At the present time the most commonly found 802.11 variant is 802.11g The Wi-Fi organization was created to ensure interoperability between 802.11b products. With a realistic throughput of 6Mbps, it is fast enough for network applications, file transfers, internet access and all other standard LAN uses.

Below is a table outlining the most common Wireless LAN technologies currently on the market.

IEEE Speed Indoor Range Outdoor Range Frequency
802.11 1-2 Mbps 100 metres up to 23 km 2.4 GHz FHSS and DQPSK FHSS
802.11b 11 Mbps 100 metres up to 23 km 2.4 GHz DSSS
802.11a 54 Mbps 100 metres up to 5 km * 5 GHz OFDM
802.11g 54 Mbps 100 metres up to 23 km 2.4 GHz OFDM

* Currently no 802.11a products on the market that support external antenna.


Simply Wireless use IEEE 802.11 technologies to create wireless networks in any industry or corporate environment. Using specialized antenna equipment, Simply Wireless use 802.11b technologies to construct wireless bridges.
