Cc99 Ff Dot
PAN [1] 802.15 (Bluetooth) Device level plus up to mandatory integrated encryption 2.45GHz. 1 or 2 Mb/s transfer, up to 10 meters low power mode & 100 meters high power mode. Minimal for eavesdropping, as usable range is very limited. Potentially high for device theft.
Cc99 Ff Dot
LAN [2] 802.11b WEP [3] 2.4GHz. 11Mb/s maximum transfer rate, up to 400 meters [7]. High if only WEP is implemented
Cc99 Ff Dot
  802.11a WEP [3] 5 GHz range. 54 Mb/s maximum transfer rate, up to 400 meters [7]. High if only WEP is implemented
Cc99 Ff Dot
  802.11g WEP [3] 2.4 GHz range. 54 Mb/s maximum transfer rate, up to 400 meters [7]. High if only WEP is implemented
Cc99 Ff Dot
  802.11i WPA [4] 802.1x Future security enhancements to existing 802.11 standards. Proposed firmware upgrade to current hardware. Projected to be low if fully implemented.
Cc99 Ff Dot
WAN [5]   WAP [6] Utilized cellular technologies (CDMA, CDPD, GSM/GPRS, etc.) with global reach at relatively slow transfer rates (9.6K on CDPD to 144K and higher on 3G CDMA). Low due to multiple strong encryption algorithms.
