What is HomeRF?

• Description HomeRF blends several technologies
  to extend beyond office WLAN solutions, making it
  the preferred wireless technology for homes and
  small offices with no network administrator.
  The open HomeRF specification is designed and
  optimized for consumer households, is ideal for
  broadband, and enables digital convergence with
  support for voice, music, TV, gaming, and data
  applications.HomeRF is important because
  telephone and entertainment devices can benefit
  from networks just as much as PCs.
