5. Discuss the technical limitations of mobile computing in terms of insufficient bandwidth, power consumption, transmission interferences, potential health hazards, and human-computer interface. by simplyww https://padlet.com/huda_mohd/tut9_Q5 en-us 2018-02-07 05:39:02 UTC 2026-03-17 01:01:36 UTC hello@padlet.com 1131119354 LIM YONG JIAN https://padlet.com/huda_mohd/tut9_Q5/wish/229428275
  • Range and bandwidth: Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA, HSUPA, 3G and 4G networks and also the proposed 5G network. These networks are usually available within range of commercial cell phone towers. High speed network wireless LANs are inexpensive but have very limited range.
  • 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.[1] (While this may seem obvious, there is considerable discussion about whether banning mobile device use while driving reduces accidents or not.[2][3]) 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.

    Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed wireless LANs are inexpensive but have very limited range.
    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. COMPUSOFT, An international journal of advanced computer technology, 3 (2), February-2014 (Volume-III, Issue-II) 559 Mobile computing should also look into Greener IT [9], in such a way that it saves the power or increases the 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 are thus assumed more likely to be involved in traffic accidents. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.
    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.

    -Security Standards: When working mobile, one is dependent on public networks, requiring careful use of Virtual Private Network (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.

    Mobile internet access is generally slower than direct cable connections, using
    technologies such as GPRS and EDGE , and more recently 3G 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  VPNs.

     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
     More car accidents are related to drivers who were talking through a mobile device. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.
     
    Human interface with device
     Screens and keyboards tend to be small, which may make them harder to use. Alternate input methods such as speech or handwriting recognition require training.
