Mobile networking devices

Mobile IT devices can use almost any wired and wireless networking technologies, as long as they are enabled to do so, either by in-built capability or via a network adapter. The options include:dial-up networking, via a modem or a mobile phone use of the global system for mobile communications (GSM), general packet radio service (GPRS) and third-generation (3G) services offered by mobile networks cable connection to "wired" local area networks (LANs), at office locations and at public internet cafes - Ethernet is the most popular wired LAN technology "wireless LANs" within office buildings, or offered at public "hot spots" where internet access is available such as internet cafes - wireless fidelity (WiFi) is the most popular wireless LAN technology Bluetooth or infra-red connection to another mobile device

UsesSometimes you don't need networking capability on the move. It might be sufficient to download and upload the information required at the start and end of the day from the office computer system.However, real-time communication with the office can be important in delivering business benefits, such as efficient use of staff time, improved customer service, and a greater range of products and services delivered. Examples include:making presentations to customers, and being able to download product information to their network during the visit quotations and interactive order processing checking stock levels via the office network interacting with colleagues while travelling - sending and receiving emails, collaborating on responses to tenders, delivering trip reports in a timely manner

Disadvantages:There can be issues with maintaining the security of devices and data - for example, these devices are easy to steal. It is also possible for data to be intercepted using some of these mobile technologies - such as Bluetooth and infrared. For more information on this see our guide on securing your wireless systems

There are also other considerations. Infrared and Bluetooth both have connectivity limitations. Infrared requires line of sight that will not pass through walls or other obstacles, while Bluetooth will pass through walls but only up to a range of 100 metres. As a consequence, many phones and laptops do not have these capabilities.
