RANGE FOR WIRELESS TECHNOLOGY & DEVICE

RANGE FOR WIRELESS TECHNOLOGY & DEVICE

1. 802.11a:

   • Uses 5 GHz RF spectrum
   • Not compatible with 2.4 GHz spectrum, i.e. 802.11 b/g/n devices
   • Range is approximately 33% that of the 802.11 b/g
   • Relatively expensive to implement compared to other technologies
   • `Increasingly difficult to find 802.11a compliant equipment

2. 802.11b:

   • First of the 2.4 GHz technologies
   • Maximum data-rate of 11 Mbps
   • Range of approximately 46 m (150 ft) indoors/96 m (300 ft) outdoors

3. 802.11g:

   • 2.4 GHz technologies
   • Maximum data-rate increase to 54 Mbps
   • Same range as the 802.11b
   • Backwards compatible with 802.11b

4. 802.11n:

   • Newest standard in development
   • 2.4 GHz technologies (draft standard specifies support for 5 GHz)
   • Extends the range and data throughput
