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.
