Mobile internet connectivity (MIC) allows users to access the internet away from their local area network using technologies like GSM, GPRS, 3G, and public WiFi networks. It works using mobile telecommunications networks or public WiFi hotspots, with data transfer rates varying by technology. While portable, MIC has disadvantages like slower speeds, less availability of information on small screens, and higher costs compared to fixed internet connections.

1. Mobile Internet Connectivity Presented By: IQxplorer [ ] TECHNICAL SEMINAR

2. 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 [ ]

3. 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 [ ]

4. 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 [ ]

5. 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 [ ]

6. 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 [ ]

7. 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

8. HOW DOES M.I.C WORK? [ ] EDGE: ENHANCES GSM N/Ws AT 3G DATA RATES DATA RATES UPTO 384Kbps IN WIDE AREA AND UPTO 554Kbps IN LOCAL AREA PUBLIC ACCESS WLANs: CONNECTED TO INTERNET VIA A WIRED TECHNOLOGY CONNECTION RANGE AROUND 100 MTRS, DATA RATES MORE THAN 4 TIMES OF 3G N/W LINKED PUBLIC ACCESS WLAN: BY OVERLAPPING THE WLAN CELLS TO BUILD LARGER WLANs

9. 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

10. DISADVANTAGES COMPARED TO FIXED LINE INTERNET CONNECTIVITY [ ] DUE TO PORTABILITY OF DEVICES, AVAILABILITY OF INFORMATION ON SCREEN IS LESS SLOWER DOWNLOADIND AND UPLOADING DATA RATES DATA RATES DECREASES AS THE DISTANCE FROM BASE STATION INCREASES RELIABILITY OF ACCESS IN RURAL AND MOUNTAIN REGIONS EXPENSIVE EQUIPMENTS

11. DEVICES ARE NOT ALWAYS COMPATIBLE WITH DEVICES USING DIFFERENT MIC TECHNOLOGY MORE EXPENSIVE THAN FIXED NETWORK INTERNET CONNECTIVITY NETWORK SECURITY SECURITY OF DEVICES AND THE DATA THEY CONTAIN [ ]

12. [ ] ISSUES IN CONTRACTS AND EQUIPMENTS COST OF ACCESS DEVICES AND SUBSCRIPTIONS COMMERCIALLY AVAILABILITY OF TECHNOLOGIES N/W DATA RATES N/W RANGE AND COVERAGE DEVICES PRICE NETWORK SERVICE PROVIDER SECURITY COMPATIBILITY ISSUES REMOTE ACCESS SUPPORT TRAINING BATTERY LIFE

13. IMPLEMENTAION ISSUES [ ] ISSUES FOR INDIVIDUAL TERIFF FOR USER NEEDS SUITABLE ACCESS DEVICE ISSUES FOR THE INSTITUTION NETWORK CHOICE COMPATIBILITY REMOTE ACCESS

14. STANDARDS ITU ETSI BLUETOOTH IEEE WLAN STANDARDS [ ]

15. 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. [ ]
