Introduction to Mobile Computing

People will be able to access web site information from more places.
At the same time, you will be able to contact them when they are
nearby, perhaps sending them an email containing a special offer when
they happen to be within a few miles of your business location.
Perhaps we will offer the ability to click a button asking to contact
our nearby friends for an impromptu get together at a local cafe, pub,
hotel, or airport. Handheld devices with wireless access are making
this possible.

Hot Spots

You’ll find the first cluster of commercial hot spots in the kind of
places that you’d expect to cater for travellers who need to stay
connected: that is, airports, railway stations, hotels, and Internet
cafes. You’ll need to open your wallet though, before you can open a
connection, and the current commercial providers will charge you
anything from a few pounds for half an hour’s access, up to around £80
per month for unlimited access.

Coverage is still patterned, and based primarily around London and the
South East, but the main providers, such as BT Openzone and Megabeam
are set to introduce more access points in the years ahead.

Promising to make WiFi access a little more comfortable is the Net
café chain Internet Exchange which has rolled out wireless access to
30 of its outlets across Britain. Instead of paying a monthly fee,
visitors can connect up for a whole day from only a fiver and surf
wirelessly while waiting for a plane at the airport.

Consider the benefits of Mobile Computing:

- Personal Communications
- Just-in-time information or location based services
- Enable spontaneous networking
- High-speed connectivity (108Mbps)

Interesting Facts

The design for the mobile multimedia environment of the 3G mobile
systems are variously known as Universal Mobile Telecommunication
Systems (UMTS) or 3G.

Wireless Home Networks

For an outlay of around £60 for a couple of wireless LAN cards, you
can create an ad-hoc network so you can work outside on your laptop,
while sharing information and Internet access through a home PC
plugged into a broadband or dial-up connection. Buy an £80 wireless
access point and the possibilities expand even further, meaning that
everyone in the house can go online at the same time by sharing one
Internet address.

What's more many new cable modems or ADSL modems come with built in
wireless access points, so that you can put an entire home network
online just by plugging one box into your broadband connection.
