3. Property of the HomeRF Working Group 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.
