HomeRF was a wireless networking specification for home devices. It was developed in 1998 by the Home Radio Frequency Working Group, a consortium of mobile wireless companies that included Proxim Wireless, Intel, Siemens AG, Motorola, Philips 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 fell into obsolescence. Description Initially called Shared Wireless Access Protocol (SWAP) and later just HomeRF, this open specification allowed PCs, peripherals, cordless phones and other consumer devices to share and communicate voice and data in and around the home without the complication and expense of running new wires. HomeRF combined several wireless technologies in the 2.4 GHz ISM band, including IEEE 802.11 FH (the frequency-hopping version of wireless data networking) and DECT (the most prevalent digital cordless telephony standard in the world) to meet the unique home networking requirements for security, quality of service (QoS) and interference immunity—issues that still plagued Wi-Fi (802.11b and g). 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 could travel within a 50-meter range of a wireless access point while remaining connected to the personal area network (PAN). Several standards and working groups focused on wireless networking technology in radio frequency (RF). Other standards include the popular IEEE 802.11 family, IEEE 802.16, and Bluetooth. Proxim Wireless was the only supplier of HomeRF chipsets, and since Proxim also made end products, other manufacturers complained that they had to buy components from their competitor. The fact that our group didn't address that conflict led to the eventual downfall of HomeRF, which occurred during an economic recession when companies already struggled to justify duplicate engineering and marketing efforts - for HomeRF, 802.11 and Bluetooth. The fact that HomeRF was developed by a consortium and not an official standards body also put it at a disadvantage against Wi-Fi and its IEEE 802.11 standard. AT&T joined the group because HomeRF was designed for high-speed broadband services and the need to support PCs, phones, stereos and televisions; but last-mile deployment occurred more slowly than expected and with slower speeds. So it was natural that the home networking market focused more on multi-PC households sharing Internet connections for email and
