Glossary
●
802.11b –
The 802.11b standard, also known as Wi-Fi, which provides
speeds up to 11 Mbps using direct-sequence spread-spectrum (DSSS)
technology and operating in the unlicensed radio spectrum at 2.4GHz,
and WEP encryption for security.
●
802.11g –
The 802.11g specification is for wireless networking at 54
Mbps using direct-sequence spread-spectrum (DSSS) technology, using
OFDM modulation and operating in the unlicensed radio spectrum at
2.4GHz, and backward compatibility with IEEE 802.11b devices, and
WEP encryption for security.
●
802.11n –
802.11n builds upon previous 802.11 standards by adding
MIMO (multiple-input multiple-output). MIMO uses multiple transmitter
and receiver antennas to allow for increased data throughput via spatial
multiplexing and increased range by exploiting the spatial diversity,
perhaps through coding schemes like Alamouti coding. The Enhanced
Wireless Consortium (EWC) was formed to help accelerate the IEEE
802.11n development process and promote a technology specification
