- Spectrum: 2.4 GHz and Infra-Red; 5.8 GHz in the future (ISM bands)
- Spread spectrum techinques:
- FHSS - Frequency-Hopping Spread Spectrum
- DSSS - Direct-Sequence Spread Spectrum
- Modulations: FHSS uses multilevel GPSK; DSSS uses BPSK and QPSK
- Channels: FHSS uses 75 non-overlapping 1 MHz channels, DSSS uses 14 overlapping 22 MHz channels
- Speed:
- 802.11 FHSS supports 2 mbps (3 mbps on non-standard) at 2.4 GHz
- 802.11b DSSS supports up to 11 mbps at 2.4 GHz
- 802.11a DSSS is estimated to support 40 mbps at 5.8 GHz
- Operational modes: Infrastructure and Ad-Hoc
- ISM band power rules: up to 1 watt in a 6dBi antenna;
for every dB of additional gain in the antenna,
decrease your power input by the same amount
(in other words, up to 4 watts EIRP)
- Security: "WEP" provides "Wired Equivelent Privacy" via encryption
