Wireless IP Phones
- Like on a wired LAN, VoIP can be setup on a wireless LAN.
- Wireless VoIP will cause most wired networks to be replaced with wireless networks for VoIP communication.
- The caller, who may be using an IP phone or any other communicating device, like a PDA or pocket PC, can make calls through the wireless LAN if he/she is within the range of the network.
Benefits of a Wireless IP Ph
- Mobility. This word itself says many things. Just to give examples:
- A medical team in a clinic needs to be able to communicate internally and externally while attending to emergencies, which implies being on the move. VoIP on a wireless LAN makes this possible for them, if each of them has a phone in their pocket.
- A factory floor team, by nature very ‘bee-like’, will find it difficult to either remain glued to a fixed phone set or going to and from it for communication. Here again, VoIP service deployed on a wireless LAN within the company premises saves time, energy and nerves; and boosts productivity.
- VoIP on Wi-Fi hotspots is a great thing for callers. Instead of taking the laptop computer along for a business lunch or some revision among classmates, one can take the IP Phone or pocket PC along.
Problems with Wireless IP Phones
There are four main issues due to which wireless IP Phones are not readily accepted everywhere:
- Poses problems of scalability for enterprises.
- Quality of Service (QoS) is not as good as with wired networks.
- The cost, in terms of money, time and skills, is higher to set up and maintain
