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 [ ]

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

TYPES OF M.I.C 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 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 M.I.C WORK? HSCSD: BASED ON GSM AND CREATED TO MEET THE DATA TRANSFER RATE LIMITATIONS OF GSM CAN ACHIEVE MAX DATA TRANSFER RATE OF 38.4Kbps BASED ON CIRCUIT SWITCHED TECHNOLOGY, SO USER ARE CHARGED FOR THE TIME DATA TAKES TO DOWNLOAD RATHER THAN AMOUNT OF DATA GPRS: A PACKET SWITCHED-BASED TECHNOLOGY THEORETICALLY MUCH HIGHER DATA-TRANSFER RATES THAN GSM OR HSCSD USERS ARE CHARGES ACCORDING TO THE AMOUNT OF DATA SENT OR RECEIVED RATHER THAN THE TIME TAKEN TO DOWNLOAD DATA TRANSFER RATE UPTO 115Kbps [ ]
