The IEEE 802.11n standard was developed to deliver improved data rates and ranges for Wireless Local Area Networks (WLANs). The standard was released as a successor to 802.11g. It offers improvements in network bandwidth through the “multiple input and multiple output” technology. This technology, called MIMO, uses multiple wireless signals and antennas, at the transmitter and receiver, for improvement in communication performance. In comparison to previous 802.11 standards, the protocol also offers range improvements with increased signal intensity. The Wi-Fi Alliance is an organization that certifies products with 820.11 wireless technologies for interoperability. A product may be designated as Wi-Fi certified for marketing purposes.

The 820.11n Standard

The 820.11n network can perform at a fast maximum speed and optimal signal range when compared to earlier 820.11 standards. However, an 820.11n device usually costs more than a device with 802.11g. Operational parameters also affect data rates. As many as four data streams can be transmitted at one time through 20MHz or 40MHz channels. Maximum data rates of 600 Mbit/s are possible when all four streams utilise a 40 MHz channel. The protocol also provides enhanced resistance against signal interference.

820.11n Technology for WLAN

Businesses have adopted 820.11n technology for WLAN to achieve improved throughput performance and greater reliability. The standard uses multiple antennas to generate both distance and speed improvements. 802.11n has the ability to operate in the 2.4 GHz and the 5 GHz frequency bands. This makes it backward compatible with users of the 11a and 11b/g standards. Comms Express is here to assist businesses with the key aspects of wireless network management.
