For traditional burglar alarm installers dealing with intrusion detection and monitored systems, it came as no shock that voice over Internet protocol (VoIP) was not the end-all and cure-all it was originally purported to be. But that’s the reality of emergency communications in some instances.
Combining technologies has allowed many systems to become part of the mainstream. One of the latest of these opportunities, is the conglomeration of power over Ethernet (PoE) with radio frequency identification (RFID).
It has been predicted that the voice over Internet protocol (VoIP) market is in the early stages of dramatic growth, but VoIP needs a compelling reason for use if its proponents expect the technology to have a lasting effect. For the home, the major advantage appears to be reduced phone cost.
How about this: Under IEEE Standard 803.2af, power can be run via datacomm cable. It's called “Power over Ethernet” (PoE). For many electrical contractors, PoE could turn out to be the greatest development in world history. But wait: Maybe it's not all that remarkable.
In spite of previous setbacks, many in the telcom industry still see potential in Wireless Local Loop (WLL) technology to complete the connection between users and their phone companies. Past attempts have not been encouraging.
