The home gateway is a high tech device ensuring continuity between the home network(s) and the in home connected devices and the external world represented by a wide area network (WAN).
The device that initially offered broadband access was a basic modem and has evolved to a wireless enabled modem router to meet the demand of consumers. But this equipment is not enough to meet the next generation of services, thus there is a need of a more capable device that we call “home gateway”. The home gateway is the device offering broadband connectivity to the home and delivering services to the home environment and the different devices & interfaces composing it.
Requirements
The next generation of services has created the new requirements for the home gateway to fulfill:
* Providing a remote management service for the home gateway & the devices beyond,
* Allowing the right device or application to connect to the right service platform with the right service class / Quality of Service,
* Recognizing and potentially uniting devices capabilities
* Playing a role in the local network to federate device capabilities and offer customers a better “integrated home environment”.
These requirements imply a device that is constantly monitoring the home network, which has obvious energy implications, both for the gateway itself and possibly for the other networked devices.
