A radio IP Phone can be described as a classy, next generation mobile IP communication device. The idea of Wireless IP Phone originated as a result of spread of Wireless LAN (WLAN) in operation organizations.
IP Phone - It integrates the standard IP phone with wireless installations and facilitates parallel voice and knowledge support to enterprise desktops on the same wireless prop. We now have supports not merely the standard packet-switch IP telephones but also the traditional circuit-switch PBX (Private Branch Exchange) interfaces. Primarily designed to supply inside offices, it combines the cost-effectiveness of an IP Phone as well as the capability of a phone.
Originally the wireless IP Phones were not meant to replace the traditional cell phones but were meant to be used exclusively within a restricted environment like the premises of the business organization or perhaps a house. The quicker models work only through WLAN that has limited geographic application. The range of operation, both indoor and outdoor, from the phone is based on the capacity of the hardware supplying the wireless access also it is evident that performance would deteriorate with distance.
IP Phone - The most recent models are created to support both WLAN and public wireless network. Mobile PCs such as laptops and palmtops can be carried anywhere and can run using various applications nevertheless they lack the compact portability of mobile phones. Public wireless networks such as cellular phones cover wide geographical areas but have limited data bandwidth. Therefore, the brand new types of Wireless IP Phones are developed combining outside architecture of laptops and also the easy portability of cellular handset so that they can switch the signal from public wireless network after coming out of the purview of WLAN. There will 't be any interruption operating through the switch.
IP Phone - The Wireless IP Phone works on battery and needs to become charged being a regular cellular phone. Older models' battery requires greater power; talk-time and uphold time will also be below those made available from a regular cellphone. However the latest models claim to be on par with regular cellular phones and provide similar features like caller identification, call hold and transfer, conference calls, selectable ring tones, phone directory etc.
However, security will be the major problem. Signals are broadcast on the air in the wireless system and is easily intercepted by outsiders who are within the array of reception. Wireless link must be secured in order to avoid such risks.
