Mobile Computing
problem in Indonesia :
• Bandwidth
Limitation
Internet access
in mobile device is slower than cables connections, using technologies such as
GPRS, EDGE and 3G/HSDPA network that recently release. High-speed wireless LAN
is not too expensive, but has a very limited range.
• Power supply
When an electric
stopcontact or portable generator is not available, mobile computers must rely
entirely on battery power. This means that the battery requires extra power
consumption.
• Interruption
Of Transmission
Many factors
could cause signal interference in mobile computing such as weather, terrain
and distance of the tool mobile computing with the transmitter signal closest
point. Besides signal reception inside the tunnel, in some buildings and rural
areas are often poor.
• User Interface
The screen and
keyboard are likely to be small sometimes make it difficult to use. Alternate
input methods like voice input or handwriting recognition requires training to
use it.
