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.
