How Wireless VoIP Phones Work

The functioning of wireless VoIP phones is similar to that of
regular VoIP phones but Wireless VoIP phones combine VoIP
technology and Wi-Fi (wLAN) systems. Users need to be in the
range of the wireless node in order to make and receive calls.
And when they are in the Wi-Fi’s reach, they are able to do a
lot of the same calling functions enabled by regular desktop
VoIP phones. When one is already equipped with a wireless local
area network as well as VoIP phones, adding wireless VoIP phones
can be a logical step.



Wireless VoIP phones are also known as VoWLAN or voice over
wireless local network areas and Wi-Fi phones. The working of
wireless VoIP phones involves a data network to which Wi-Fi
equipment is connected. The network itself can either be
independent, or connected to the Internet or the public phone
system. The equipment enables high-speed wireless connection to
unlimited access points.



Each access point has an antenna to catch the signal from the
Wi-Fi equipment and broadcast it in a 300-foot radius or a hot
spot. Within the radius all Wi-Fi enabled laptops, personal
digital organizers and wireless phones can tune into the signal.



In wireless VoIP phones, the voice is converted into segments
of data for transmission from the phone antenna to the Wi-Fi
radio waves and then received by the data network. Here the data
segments reverse the process to reach an extension or the
traditional phone network. In other words, an extension can be
carried around.



Although there is no argument about wireless VoIP phones being
advantageous, they have their share of shortcomings as well.
Fore one, they can not yet completely replace hard-wire VoIP
phones mainly due to lack of reliability and the limited
functions of wireless phones currently available in comparison
to desktop phones.



However the biggest disadvantage in wireless VoIP phones is the
limit on the number of simultaneous calls that can be made. The
maximum number of calls in each wireless system cannot exceed
five or ten. This seriously undermines its call handling
capability in a large corporate environment.



Nevertheless, the dramatic reduction in operational costs has
made it possible for wireless operators with high quality
compressed VoIP to bring the ease and comfort of cordless
calling to the VoIP world.
