Mobile Internet Connectivity
INTRODUCTION
WHAT IS IT?
Technology that facilitates internet access by enabling the user to access the internet while away from their LAN of their institution
Technology that allows users to connect to the internet with high data rates than home-use broadband connections
TYPES OF M.I.C
Global system for mobile communication(GSM):for voice communications and small data transfer
High speed circuit switched data(HSCSD):allows GSM for faster data transfer(4 times)
General packet radio services(GPRS):to give increased data rates, charging based on the amount of data transfer
Third generation(3G) mobile:increased data rates(maximum upto 2mbps) and wide range of services
Enhanced data GSM environment(EDGE):co-exists with GSM. Allow GSM operators for 3G spectrum providing users a data rate upto 554mbps
Public access WLAN:enable users to access internet in localised hotspots via a WLAN access card and a PDA or laptop
Linked public access WLANS :to page link number of public access WLANS for high speed access
Public access WLAN and mobile telecommunication convergences:allows users / devices to swap between a telecommunication technology (eg. GPRS, 3G) and PAWLAN to enjoy the highest available data rate, depending on their geographical location
HOW DOES IT WORK?
(A)MOBILE TELECOMMUNICATIONS
GSM
HSCSD
GPRS
3G MOBILE
EDGE
(B)PUBLIC ACCESS WLANs
LINKED PUBLIC ACCESS WLANS
GSM :A CIRCUIT SWITCHED-BASED TECHNOLOGY MAINLY FOR VOICE TRANSMISSION AND TO CARRY DATA SUCH AS TEXT TO ACCESS EMAIL AND THE INTERNET.
LIMITED DATA RATES UPTO 9.6Kbps
SLOW COMMERCIAL INTERNET ACCESS
