Area NetworksTM

• Report on Recent FCC Ruling on Wide Band
  Frequency Hopping

2
Background

• Over that last two years the FCC has been
  evaluating a modification to FCC Part 15 section
  247 which regulates the operation of devices in
  the ISM Bands.
• Rule change proposed by HomeRF
• The proposal was to modify the rule to allow for
  wide band frequency hopping.
• The IEEE has opposed the change due to the
  potential increased interference.

WBFH Ruling

• Recently (August 22, 2000) amended Part 15
  section 247 (See FCC 00-312).
• The purpose was to allow for high rate Frequency
  Hopping Spread Spectrum systems in the 2.4 GHz
  ISM Band.
• Intended to give parity of data rates with DSSS
  systems (e.g. IEEE 802.11b)

Impact on 802.15 TG2

• Currently we are focusing our efforts the mutual
  impact of Bluetooth and IEEE 802.11
• With this amended rule 10 Mbps HomeRF systems are
  now allowed.
• This represents a new interference source in the
  marketplace.

Impact on 802.15 TG2

• Should we model the impact of the interference of
  HomeRF on Bluetooth?
• When should we start?
• Should we model the impact of the interference of
  HomeRF on 802.11?
• When should we start?
