Range and Bandwidth:
Using mobile internet access is much slower than using a direct cable, For example using a cell phone's connection such as GPRS, EDGE, HSDPA, HSUPA, 3G, 4G, 5G. All these internet access are available within a range commercial cell phone tower. Nevertheless using technology such as 3G or 4G is considerably cheaper than using high speed wireless networks like LAN's and LAN's have a very limited range.
Security Standard:
Working with a mobile it depends on the public networks used. Users should be careful as attacking a mobile device on these networks are easily done.
Power Consumption:
The other limitation to using mobile devices is the batter. When and If a power outlet or portable generator isn't available the usability of the device is compromised. As mobile computers rely entirely on it's battery for power. As mobile devices are very compact, More compact batteries with higher capacities are required. These compact high capacity batteries are normally more expensive.
Tranmission Interferences:
Terrain, Weather are easily interfered due to these reasons and the range from the closest signal point may be disrupted from normal use. Reception in Tunnels, Some Buildings and Rural Areas are usually really poor.
Potential Health Risks:
People who are using their mobile devices are typically distracted, Usage while walking or driving as a dangerous habit a lot of users face which leads to traffic accident, Questions regarding mobile phone radiation and health are raised. Such as over-exposure to blue light causing lack of quality sleep.
Human Interface with Device:
Alternate input strategies like speech or handwriting recognition need training using services such as voice control and map navigator are the examples.
