Limitations of Mobile Computing


 Insufficient bandwidth: Mobile Internet access is generally slower than direct cable
connections, using technologies such as GPRS and EDGE, and more recently HSDPA and
HSUPA3G networks. These networks are usually available within range of commercial cell
phone towers. Higher speed wireless LANs are inexpensive but have very limited range.
 Security standards: When working mobile, one is dependent on public networks,
requiring careful use of VPN. Security is a major concern while concerning the mobile
computing standards on the fleet. One can easily attack the VPN through a huge number of
networks interconnected through the line.
 Power consumption: 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.
 Transmission interferences: 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.
 Potential health hazards: People who use mobile devices while driving are often
distracted from driving and are thus assumed more likely to be involved in traffic
accidents.(While this may seem obvious, there is considerable discussion about whether
banning mobile device use while driving reduces accidents or not.). Cell phones may
interfere with sensitive medical devices. Questions concerning mobile phone radiation and
health have been raised.
 Human interface with device: Screens and keyboards tend to be small, which may make
them hard to use. Alternate input methods such as speech or handwriting recognition
require training
