Abstract
The ubiquity of broadband connectivity and the advancements in home networking technologies introduces into market a new breed of consumer premises equipment termed as home gateways or residential gateways. Home gateway device provides the consumer, benefits such as broadband Internet connection sharing, Firewall security, VPN connectivity, IP telephony, audio/video streaming, Wireless LAN connectivity etc.

At present, home gateway devices are available in market in various physical device personalities or form factors like the SOHO Router home gateway, cable Router/MTA home gateway, DSL Router/IAD home gateway, STB home gateway etc. Each of the home gateway device personality is targeted for a particular segment and for a particular usage scenario of the end consumer. This paper discusses the various personalities of the home gateway devices along with its usage scenario.

Although the home gateway device is a consumer communication equipment with a low price point, engineering wise it is a highly sophisticated device demanding a lot of design, integration, development and testing challenges both on the hardware and on the software front. This paper setails the hardware, software technical architecture and specifications of the home gateway devices and lists out the engineering design challenges (along with the possible solutions) faced by a home gateway product designer or a home gateway silicon designer.
