Mobile Internet Connectivity
[attachment=65655]
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
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
HOW DOES M.I.C WORK?
MOBILE DEVICES FOR GPRS
MODE CLASS:CLASS A SUPPORTS GPRS AND OTHER GSM SERVICES,SUCH AS SMS AND VOICE,SIMULTANEOUSLY
CLASS B CAN MONITOR GSM AND GPRS CHANNELS SIMULTANEOUSLY, BUT ONLY ONE SERVICE AT A TIME
HIGHER THE CLASS , THE FASTER THE UPLOAD CAPABILITIES OF A DEVICE
3G MOBILE :A SET OF STANDARDS ALLOWS MIC ROAMING AT ENHANCED SPEED
PACKET MODE TECHNOLOGY ALLOWS VOICE, TEXT AND MULTIMEDIA SERVICES ON ONE DEVICE
SPEED RANGING FROM 64Kbps TO 384Kbps/2Mbps
ADVANTAGES COMPARED TO FIXED LINE INTERNET CONNECTIVITY
PORTABILITY OF DEVICES AND SERVICES
OFFERS A HIGH DEGREE OF COMPATIBILITY AND INTER-OPERABILITY WITH SERVICES
USERS CAN ACCESS THEIR INTRANET AND MAIL SERVICES WHEN AWAY FROM THEIR INSTITUTION
CONCLUSION
Although mobile internet connectivity has many advantages and disadvantages to its side, it provides a greater chance for compatibility and portability of services with a varieties of flavours.
