LimitationsInsufficient bandwidth: Mobile Internet access is generally slower thandirect cable connections, using technologies such asGPRSandEDGE, and

more recentlyHSDPAandHSUPA3Gnetworks.

Security standards: When working mobile, one is dependent on publicnetworks, requiring careful use ofVPN. Security is a major concern whileconcerning the mobile computing standards on the fleet.

Power consumption: When a power outlet or portable generator is notavailable, mobile computers must rely entirely on battery power. Combinedwith the compact size of many mobile devices,

Transmission interferences: Weather, terrain, and the range from thenearest signal point can all interfere with signal reception. Reception in

tunnels, some buildings, and rural areas is often poor.

All smart phones, as computers, are preferred targets of attacks. These attacks exploit

weaknesses related to smart phones that can come from means of communication

likeSMS, MMS, wifi networks, andGSM.

Different security counter-measures are being developed and applied to

Smartphone, from security in different layers of software to the dissemination of

information to end users.

capabilities of the mobile network continue to improve as the processing horsepower

residing in the phone and on the network grows.
