Answer 1

Mobile Computing is a generic term describing your ability to use technology 'untethered', that is not physically connected, or in remote or mobile

Answer 2

Mobile computing is human–computer interaction by which a computer is expected to be transported during normal usage, which allows for transmission of data, voice and video. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.

Answer 3

we can do mobile computin wit java j2me i think specific computin is related to only a particular section like only games, or application etc

Answer 4

Hi,
Mobile computing is very big issue. fr its details and for softwares u can refer Sun's website which will be very useful.
netbeans_mobility-5_5-win.exe find out this software for its development

Answer 5

computing of any type without physical connection

Answer 6

Mobile Computing is a generic term describing your ability to use technology 'untethered', that is not physically connected, or in remote or mobile (non static) environments. The term is evolved in modern usage such that it requires that the mobile computing activity be connected wirelessly to and through the internet or to and through a private network. This connection ties the mobile device to centrally located information and/or application software through the use of battery powered, portable, and wireless computing and communication devices. This includes devices like laptops with wireless LAN or wireless WAN technology, smart mobile phones, wearable computers and Personal Digital Assistants (PDAs) with Bluetooth or IRDA interfaces.

Many types of mobile computers have been introduced since the 1990s, including the:

Laptop computer
Subnotebook
Personal digital assistant (PDA)
Portable data terminal (PDT)
Mobile data terminal (MDT)
Tablet personal computer
Smartphone


History of mobile devices
Originally, electronic devices such as radio transmitters, wireless communications systems, and the like, were base stations, operated at fixed locations, typically with large antenna towers. Widespread use of automobiles gave rise to smaller devices operating at 6 volts. In the 1950s, the transition to 12 volt automotive electrical systems gave rise to a large number of 12 volt devices, such as two-way radios, referred to as mobile rigs. A large industry, with companies such as Motorola sprung up to support the growing need for mobile devices, such as taxicab radios, police radios, and other 12 volt underdash equipment, as well as trunk mount systems. Today there are a wide variety of mobile computing platforms, including dash-mount VGA displays, and computers that can provide GPS and other navigation functions for automobile users.


Base-Mobile-Portable hierarchy
In ham radio, there is a base-mobile-portable hierarchy, as follows:

Base station: fixed location, incorporated into a building or other architecture;
Mobile: attached to or in a vehicle or used by a mobileer;
Portable: worn or carried. (The word "portable" derives from French "porter" = "to wear", but also includes handheld devices such as handie-talkies, walkie talkies, handheld computers, as well as wearable computers).




Mobile Computing: In-Vehicle Computing and Fleet Computing
Many commercial field forces deploy a ruggedized portable computer such as the Panasonic Toughbook 29 with their fleet of vehicles. This requires the units to be anchored to the vehicle for driver safety, device security, and user ergonomics. The rugged laptops are rated for severe vibration associated with large service vehicles and off-road driving, and harsh environmental conditions of constant professional use such as in EMS, fire and public safety.

Other elements that enables the unit to function in vehicle:

Operating Temperature: A vehicle cabin can often experience temperature swings from -20F to +140F. Computers typically must be able to withstand these temperatures while operating. Typical fan based cooling has stated limits of 95F-100F of ambient temperature, and temperature below freezing require localized heaters to bring components up to operating temperature(based on independent studies by the SRI Group and by Panasonic Toughbook R&D).
Vibration: Vehicles typically have considerable vibration that can decrease life expectancy of computer components, notably rotational hard drives.
Daylight, or sunlight readability: Visibility of standard screen becomes an issue in bright sunlight.
Touchscreens: These enable users to easily interact with the units in the field without removing gloves.
High-Temperature Battery Settings:. Lithium Ion batteries are sensitive to high temperature conditions for charging. A computer designed for the mobile environment should be designed with a high-temperature charging function that limits the charge to 85% or less of capacity.
External wireless Connections, and External GPS Antenna Connections: Necessary to contend with the typical metal cabins of vehicles and their impact on wireless reception.
Several specialized manufacturers such as Gamber Johnson and LedCo build mounts for vehicle mounting of computer equipment for specific vehicles. The mounts are built to withstand the harsh conditions and maintain ergonomics.

Specialized installation companies such as TouchStar Pacific specialize in architecting the mount design, assembling the proper parts, and installing them in a safe and consistent manner away from airbags, vehicle HVAC controls, and driver controls. Frequently installations will include a WAN modem, power conditioning equipment, and a WAN, WLAN, and GPS antenna mounted external to the vehicle.
