HOME RF AND BLUETOOTH A WIRELESS DATA COMMUNICATION REVOLUTION IN THE MAKING
[attachment=23778]
• Lack of horizontal market focus (infrastructure build-up has been slow)
• Battery life has been a big problem
• Standards have not kept pace with the Internet
• Ease-of-use factors have been poor - configuration, maintenance, and
manageability has been difficult
• Lack of seamless communications between different standards
• Security has been an second class citizen
• The case for value .vs. cost is unclear
– Wireless PCMCIA adapters cost $500-$700, Access points cost
$1200-1800. 10/100 Ethernet adapters cost $150
– Gross mismatch between cost and speed
BRIEF HISTORY RF STANDARD
802.11
– IEEE standard for the enterprise market
– work began 1992, Final standard published 1995
– 2.4 GHz, 2 Mbps, 50 m, CSMA/CA, DCF and PCF
• HIPERLAN
– ETSI BRAN (formally RES10) RF standard
– work began early 1992, Final standard published late 1995
– 5.15 GHz and 17.1 GHz, 23.5 Mbps, 50 m, EY-NPMA
• HomeRFTM
– RF standard for tetherless home networking. 5 core members (Intel, HP, Microsoft,
Compaq, IBM) + 63 member companies (pay $$ to become members) (as of 12/8/98)
– official launch in March 1998, Final standard (v1.0) expected early 1999
• Bluetooth
– RF standard for the business user. 5 core members (Ericsson, Nokia, Toshiba, Intel,
IBM, Intel), 278 member companies (membership is free) (as of 12/8/98)
– official launch in February 1998, Final standard expected 1999
HOME RF TM -MISSION STATEMENT
“To enable the existence of a broad range of
interoperable consumer devices, by establishing an
open industry specification for unlicensed RF digital
communications for PCs and consumer devices
anywhere, in and around the home.”
