Wireless LAN (WLAN) Resources
By most accounts, Wireless Local Area Network (WLAN) first began in 1971 when a wireless computer network was implemented (dubbed the AlohaNet) at the University of Hawaii. In 1990 AT&T, developed WaveLAN, a Direct Sequence Spread-Spectrum (DSSS) that exhibited superior interference immunity. After many versions of designs using discrete components, in 1996, Harris (now Intersil) introduced their PRISM WLAN chipset. Needing a standard to guarantee interoperability, in 1997, the Institute for Electrical and Electronics Engineers published the first specification for IEEE 802.11 - 2.4 GHz, 2 Mbps, using Frequency Hopping (FH) and DSSS. In 1998, the ETSI HomeRF standard was developed for 2.4 GHz, 1.6 Mbps, Wideband Frequency Hopping. 1999 saw the publication of the IEEE 802.11b standard - 2.4 GHz, 11 Mbps, DSSS.|
With the unlicensed 2.4 GHz ISM band being crowded with existing WLAN, Bluetooth, ZigBee and microwave ovens, and with a need for higher datarates, in 1999 the IEEE released its 802.11a standard, which moved up into the 5 GHz ISM band, and provided 54 Mbps, OFDM data. In 2000, the ETSI HiperLAN2 emerged - 5 GHz, 54 Mbps, OFDM, connection-oriented QoS. Alas, the difficulty with mass-producing high yielding, inexpensive systems at 5 GHz forced, combined with revolutionary modulation methods, drove the IEEE in 2003 to provide a new high datarate spec for operation back in the 2.4 GHz band, but offering the same datarate as the spec 802.11g - 2.4 GHz, 54 Mbps, OFDM, compatible with 802.11b. Now, 802.11n is in the works for 2.4 GHz operation yielding greater than 100 MHz datarates.
