Mobile computing allows people to use IT without being tied to a single location. Any business with staff that works away from the office can benefit from using it.
Mobile application development can also change the way you do business - new technologies lead to new ways of working, and new products and services that can be offered to your customers. They can bring new business opportunities - for example the spin-off businesses surrounding the mobile phone industry.
Mobile technology is exactly what the name implies - technology that is portable. Examples of mobile IT devices include; laptop computers, palmtop computers or personal digital assistants, mobile phones and 'smart phones' - high-end phones with more advanced capabilities, global positioning system (GPS) devices, wireless debit/credit card payment terminals
Mobile application development can be applied for the devices that can be enabled to use a variety of communications technologies such as:
wireless fidelity (Wi-Fi) - a type of wireless local area network technology
Bluetooth - connects mobile devices wirelessly
'third generation' (3G), global system for mobile communications (GSM) and general packet radio service (GPRS) data services - data networking services for mobile phones
dial-up services - data networking services using modems and telephone lines
virtual private networks - secure access to a private network
It is therefore possible to network the mobile device to a home office or the internet while travelling. Mobile computing can improve the service you offer your customers. For example, you could use your laptop computer to give a presentation. You could then transfer PDFs of your product literature to your client's computer. Or you could connect remotely to your diary to arrange a follow-up appointment. Alternatively, you can enable customers to pay for services or goods without having to go to the till. For example, by using a wireless payment terminal diners can pay for their meal without leaving their table.
More powerful solutions can link you directly into the office network while working off site, for instance to access your company's database or accounting systems. For example, you could set up a new customer's account, check prices and stock availability, and place an order online. This leads to great flexibility in working - for example, enabling home working, or working while travelling. Increasingly, networking 'hot spots' are being provided in public areas that allow connection back to the office network or the internet.
Mobile phones and their network vary very significantly from provider to provider and country to country. However the basic communication method of all of them is through the electromagnetic microwaves with a cell base station. The cellular companies have large antennas, which are usually mounted over towers, buildings and poles. The cell phones have low-power transceivers that transmit voice and data to the nearest sites usually within the 5 to 8 miles (8 to 13 kilometers away).
When a mobile device or phone is turned on, it registers with the mobile telephone exchange or switch. It is a unique identifier and is alerted by the mobile switch when there is an incoming phone call. The handset listens for the strong signals from the nearest base stations. When a user moves, the mobile device handoff to various nearest sites during phone calls or while waiting between calls it reselect the nearest cell phone sites.
