technology is moving towards the future of the wireless web. Mobile devices
such as palmtops, handhelds, and cellular phones are becoming all the rage.
People want these devices to do everything from access their e-mail accounts,
to utilize the Internet, to access personal and corporate information.
of service that is available is a technology called SMS (Short Messaging
Service). SMS is the technology that allows text messages to be received and
sent over mobile devices.
SMS is a
very inexpensive method of communication. 160 characters take up as much room
as a one-second voice call. Messages are delivered immediately (or when the
phone is turned on). Like e-mail, they can also be reviewed or stored in your
phone for as long as you wish. SMS messages can also be sent out to huge groups
of people with the single press of a button.
allows for unified messaging. This is where SMS can take on a number of
different message formats (including voice mail, e-mail and fax) and allows
users to access them from their mobile device.
Europeans send each other well over a billion messages a month. This fact may
be hard to believe if you live in the United States, where SMS
service is practically nonexistent.
are a number of reasons why the SMS is slow to take off in the United States. The main reason
is that the United States does not use the
digital wireless interface standard (GSM—more on this in a moment) that is
necessary for SMS to function. Although GSM is starting to grow in the United States, the change is
mobile devices can be fitted with SIM (Subscriber Identification Module) cards.
These are plastic cards that, when placed in the back of a mobile device, store
various types of information.
might be thinking that typing on a miniature telephone keypad is hard, even for
nimble little fingers. Well, most devices contain 'predictive input', a sort of
software that allows the device to guess what you are writing and try to finish
the word for you. Besides, most people abbreviate their words anyway. Unless
you're not trying to write a novel on your phone you should have no problems.
device to utilize SMS, it must be SMS-enabled. Also, the device must be
connected to one of the GSM networks that support SMS. Check with your device
supplier to determine whether a device is able to receive SMS messages.
means that only devices with SMS technology built into them will be able to
access and utilize SMS. Most mobile device manufactures such as Ericcson, Motorola, and Nokia offer SMS-enabled products.
stands for Global Systems for Mobile Communication. SMS resides on GSM networks
for SMS communication.
the early 1980's, analog cellular telephone systems were growing rapidly in Europe. Each country
started developing it's own system. These systems were
incompatible with everyone else's equipment and operation. It was not a good
situation. For one, mobile equipment was limited to limited to their national
boundaries. Thus, markets were limited for each type of equipment.
Europeans realized this early on, and created a group to propose a new,
universal system. This new universal system became GSM. Eventually commercial
services became available in the early 1990's and GSM networks have spread
GSM is a
digital system, which is what allows SMS features to exist. Most countries use
the GSM standard—the United States is one of the
few countries to favor use of CDMA and TDMA standards over GSM (though there
are GSM networks throughout the US). CDMA and TDMA
allow extremely limited SMS capabilities.
allows for messages to be sent from point-to-point, or in a cell-broadcast mode
world requires more and more Internet functionality from their mobile devices.
And GSM, in all its complexity, is having a hard time keeping up. GSM was never
designed to service text information, let alone large amounts of text such that
the wireless Internet would provide. Using GSM for anything more than SMS would
become a slow and cumbersome method.
that said, it seems that GPRS (General Packet Radio Service) is being touted as
the new best thing. GPRS would allow the sending of Internet information
through mobile devices at a high speed.
Experts believe that GPRS will be capable of delivering
information at a speed of up to 100,000 bits per second.
GSM can deliver information at a speed of 9,600 bits per second.
point-to-point SMS message is where a user sends a message to another
subscriber in their service. Once their message is sent, an acknowledgement of
receipt is provided to the sender.
Cellbroadcast mode, or point-to-omnipoint, SMS messages are those such as traffic updates
or news updates that are sent by services to multiple subscribed users within a
given cell area.
you've never tried SMS, I urge you to check it out. It's an incredibly
practical, reliable, and affordable method of communication.
