HomeRF
HomeRF was a wireless networking specification for home devices. It was developed in 1998 by the HomeRF Working Group, a consortium of mobile wireless companies that included Proxim Wireless, Siemens, Motorola, Philips[1] and more than 100 other companies. The group was disbanded in January 2003 after other wireless networks became accessible to home users and Microsoft began including support for them in its Windows operating systems. As a result HomeRF has fallen into obsolescence. The archive of the HomeRF Working Group is maintained by Palo Wireless.

[edit] Description
HomeRF used frequency hopping spread spectrum (FHSS) in the 2.4 GHz frequency band and in theory could achieve a maximum of 10 Mbit/s throughput; its nodes can travel within a 50 meter range of an wireless access point while remaining connected to the personal area network (PAN).
HomeRF allowed both voice telephone signals and data signals to be exchanged over the same wireless network. Therefore, in HomeRF, cordless telephones and laptops, for example, could share the same bandwidth in the same home or office.
Available HomeRF local area networks (LANs) supported 1.6 Mbit/s, relatively slow compared to technology marketed under the Wi-Fi brand name. For example, second generation 802.11b LANs supported 11 Mbit/s. 802.11n reaches a maximum of 600 Mbit/s.
Several standards and working groups focused on wireless networking technology in radio frequency (RF). Standards include the popular IEEE 802.11 family, 802.16, and Bluetooth.
