1. Wireless @ UW Terry Gray UW Computing & Communications 14 March 2000

2. WIRELESS CATEGORIES Wireless by Purpose –Point-to-Point links –Access networks Wireless by Spectrum –Infrared –RF –Optical

3. Wireless RF by Range PAN/HAN (Personal/Home-Area-Network) –Bluetooth –HomeRF/SWAP LAN (Local-Area-Network) –IEEE 802.11 –ETSI HiperLAN2 MAN (Metro-Area-Network) –LMDS WAN (Wide-Area-Network) – Ricochet –CDPD –etc, etc, etc

4. LAN WIRELESS STANDARDS IEEE 802.11 2.4GHz, 1-2Mbps, FHSS, DSSS IEEE 802.11b 2.4Ghz, 11Mbps DSSS IEEE 802.11a 5Ghz, 24Mbps ETSI HiperLAN2 5Ghz, 54Mbps, TDMA

5. 802.11 ISSUES Network Design, esp. Topology Access control Security Compatibility Interference Relation to Bluetooth, HomeRF, etc

6. ROAMING ISSUES Layer 2 (802.11) vs. Layer 3 (Mobile IP) Vendor incompatibility LAN vs. WAN

7. POLICY ISSUES Part of campus network infrastructure Want to encourage small-scale deployments with minimum overhead, but coordination needed to avoid interference Large-scale deployments need to be coordinated by C&C

8. FUTURES 802.11a for link technology? Mobile IP for roaming? EAPOE for access control?

9. CONCLUSIONS Wireless is very addictive It will be very popular It will be very problematic The dust has not settled
