Mobile Computing
Mobile Computing is a term describes technologies that enable the users to access the network from any place at any time. Ubiquitous computing and nomadic computing are synonymous with mobile computing .Mobile computing technology is improving and becoming more feasible.
Mobile computing involves connection with the network and data processing. Using phones
from anywhere in the world is not mobile computing because there is no data processing
involved. Using a laptop while moving is not mobile computing if there is no connection to a
network.
Wireless data connections used in mobile computing take three general forms.
Cellular data service uses technologies such as GSM, CDMA or GPRS, and more recently 3G networks such as W-CDMA, EDGE or CDMA
Wi-Fi connections offer higher performance, either on a private business network or accessed through public hotspots
Satellite Internet access covers areas where cellular and Wi-Fi are not available and may be set up anywhere the user has a line of sight to the satellite's location, which for satellites in geostationary orbit means having an unobstructed view of the southern sky.
Some enterprise deployments combine networks from multiple cellular networks or use a mix of cellular, Wi-Fi and satellite and mobile virtual private network (mobile VPN)handles the security concerns, performs the multiple network logins automatically and keeps the application connections alive to prevent crashes or data loss during network transitions or coverage loss. Mobile communications popularity grew many folds over the past few years and is still growing to a greater extent. Through WAP development of Mobile Computing applications is becoming easy and affective.
The traditional mobile phone only had a simple black and white text display and could send / receive voice or short messages. Today, however, mobile phones migrate more and more toward PDAs. Mobile phones with full color graphic display, on the Internet browser are available.
Mobile Computing comprises of applications in various fields such as commercial, medical, defense, networking and electronic devices etc. Different devices that work on the principal of mobile computing are PDA’s, Laptops and cell phones.
