Cordless VoIP telephones enable service providers offering high-quality audio to leverage the Internet in order to expand home telephony services, thereby opening up a new world of IP applications and services. The cordless VoIP phone handset communicates via RF transmission with a base station at the subscriber's premises that is connected to the IP network by either an Ethernet cable or a Wi-Fi connection. The phone maintains an effective range that enables full mobility at the subscriber's premises and within close proximity outdoors.
DSP Group™'s cordless-over-IP (CoIP) software development kit (SDK) and accompanying reference applications help consumer electronics (CE) manufacturers reduce development efforts and time to market. The CoIP SDK is a comprehensive framework enabling rapid and easy introduction of new embedded features within enhanced low-to-high-end products. These products include home PBXs with DECT access points, home gateways (HGWs) with VoIP and cordless capabilities, fully featured VoIP phones, and fully featured cordless VoIP analog adapters. |
