Mobile Computing

What is Mobile Computing ?

“Mobile computing is associated with mobility of hardware, data and software in computer applications.”

“Information at any time, any place, and in any form. Whether in the office, at home or virtually any place on earth.”

“Mobile computing is the use of computers in a non-static environment.”

• Nomadic/Ubiquitous Computing.

CHALLENGES AND LIMITATIONS

•Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA and HSUPA 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed wireless LANs are inexpensive, but have very limited range

Insufficient

bandwidth

•When working mobile one is dependent on public networks, requiring careful use of VPNs.

Security standards

•When a power outlet or portable generator is not available, mobile computers must rely entirely on battery power. Combined with the compact size of many mobile devices, this often means unusually expensive batteries must be used to obtain the necessary battery life.

Power consumpt

ion

•Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.

Transmission

interferences

•More car accidents are related to drivers who were talking through a mobile device. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.

Potential health

hazards

•Screens and keyboards tend to be small, which may make them harder to use. Alternate input methods such as speech or handwriting recognition require training

Improved

decision making:

•The ability to collect, access and evaluate critical business information quickly and accurately means better decision making.Increased

productivity and reduced

costs

•Mobile computing can lead to increased individual productivity, increased sales per sales person, more service calls per repair person, less time spent by professionals on administrative work, and much more.Improve

•Mobile computers gives your field worker the ability to answer customer questions, check order status and provide other services anytime their customers need them from wherever they happen to be.
