The Basics Of Mobile Data Communications Powered By Docstoc
					Most people today are familiar with data plans on cell phone systems. It
allows them to access their email and the internet from their cell
phones. However, most people are not familiar with mobile data
communications. This is something that, while similar to the
aforementioned cellular plans, is actually used to transmit user to user
information.Commonly used by emergency personnel, mobile data
communications allow police, fire, and EMTs to transmit and receive
critical information in the form of data. Some might wonder why this
method is preferred to traditional radio communications, and the question
is well asked and answered.In the military, radio personnel are trained
in communications techniques to keep confusion to a minimum. Because
certain letters have a similar sounds when spoken and can be easily
confused with another, a system was needed to help reduce this problem to
a minimum. Letters like T and P have a similar sound, so instead of
simply saying T or P, they would say a word that began with the
appropriate letter. T was now Tango and P was now Papa.This ability to
keep confusion to a minimum was further reinforced by standardized
training and consistent use of these words representing letters. However,
while this greatly reduced misunderstanding, it did not eliminate
communication errors. Today, it is necessary to be able to communicate
much more specific and lengthy information in certain emergency
situations; therefore, a new system was needed.The easiest solution would
be to transmit the raw data from one point to another. This would allow
the end user or recipient the ability to receive accurate information
without the possibility of transmission error. The other benefit of this
type of mobile data communication is that it helped keep information more
secure than it would be if transmitted over open airwaves where anyone
could be listening.The secure aspects of this kind of site to site com
appealed to the military, the police, and other public servants engaged
in emergency response. In the case of medical information and the
requisite security concerns, raw data transmission seems the best option
available.Until recent years, this type of transmission required high
specialized equipment and was very cost prohibitive. The other draw back
was the speed of the transmission. In the early days, it might take just
as long to transfer the data to the end user who needed it, as it would
be to relay it via voice transmission. Today, with the technological
advancements that have been made, mobile data transmission has never been
more secure and quick.There are specific companies that specialize in
mobile data transmission. While one would think that cellular companies
would be leading the pack, the security requirements and technology while
similar are very different. This means that specialized equipment is
still a necessity although not quite as cost prohibitive as years
past.The sheer numbers of emergency responders has increased as the
population has increased. This means that proprietary systems are
necessary to keep information from becoming confused with multiple
transmissions.
