Mobile Internet Connectivity

  1. 1. Mobile Internet Connectivity Presented By: IQxplorer [ ] TECHNICAL SEMINAR
  2. 2. INTRODUCTION <ul><li>WHAT IS IT? </li></ul><ul><li>Technology that facilitates internet access by enabling the user to access the internet while away from their LAN of their institution </li></ul><ul><li>Technology that allows users to connect to the internet with high data rates than home-use broadband connections </li></ul>[ ]
  3. 3. TYPES OF M.I.C <ul><li>Global system for mobile communication(GSM):for voice communications and small data transfer </li></ul><ul><li>High speed circuit switched data(HSCSD):allows GSM for faster data transfer(4 times) </li></ul><ul><li>General packet radio services(GPRS):to give increased data rates, charging based on the amount of data transfer </li></ul><ul><li>Third generation(3G) mobile:increased data rates(maximum upto 2mbps) and wide range of services </li></ul><ul><li>Enhanced data GSM environment(EDGE):co-exists with GSM. Allow GSM operators for 3G spectrum providing users a data rate upto 554mbps </li></ul>[ ]
  4. 4. TYPES OF M.I.C <ul><li>Public access WLAN:enable users to access internet in localised ‘hotspots’ via a WLAN access card and a PDA or laptop </li></ul><ul><li>Linked public access WLANS :to link number of public access WLANS for high speed access </li></ul><ul><li>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 </li></ul>[ ]
  5. 5. HOW DOES IT WORK? <ul><li>(A)MOBILE TELECOMMUNICATIONS </li></ul><ul><ul><li>GSM </li></ul></ul><ul><ul><li>HSCSD </li></ul></ul><ul><ul><li>GPRS </li></ul></ul><ul><ul><li>3G MOBILE </li></ul></ul><ul><ul><li>EDGE </li></ul></ul><ul><li>(B)PUBLIC ACCESS WLANs </li></ul><ul><ul><li>LINKED PUBLIC ACCESS WLANS </li></ul></ul><ul><li>GSM :A CIRCUIT SWITCHED-BASED TECHNOLOGY MAINLY FOR VOICE TRANSMISSION AND TO CARRY DATA SUCH AS TEXT TO ACCESS EMAIL AND THE INTERNET. </li></ul><ul><ul><li>LIMITED DATA RATES UPTO 9.6Kbps </li></ul></ul><ul><ul><li>SLOW COMMERCIAL INTERNET ACCESS </li></ul></ul>[ ]
  6. 6. HOW DOES M.I.C WORK? <ul><li>HSCSD: BASED ON GSM AND CREATED TO MEET THE DATA TRANSFER RATE LIMITATIONS OF GSM </li></ul><ul><ul><li>CAN ACHIEVE MAX DATA TRANSFER RATE OF 38.4Kbps </li></ul></ul><ul><ul><li>BASED ON CIRCUIT SWITCHED TECHNOLOGY, SO USER ARE CHARGED FOR THE TIME DATA TAKES TO DOWNLOAD RATHER THAN AMOUNT OF DATA </li></ul></ul><ul><li>GPRS: A PACKET SWITCHED-BASED TECHNOLOGY </li></ul><ul><ul><li>THEORETICALLY MUCH HIGHER DATA-TRANSFER RATES THAN GSM OR HSCSD </li></ul></ul><ul><ul><li>USERS ARE CHARGES ACCORDING TO THE AMOUNT OF DATA SENT OR RECEIVED RATHER THAN THE TIME TAKEN TO DOWNLOAD </li></ul></ul><ul><ul><li>DATA TRANSFER RATE UPTO 115Kbps </li></ul></ul>[ ]
  7. 7. HOW DOES M.I.C WORK? [ ] <ul><li>MOBILE DEVICES FOR GPRS </li></ul><ul><ul><li>MODE CLASS:CLASS A SUPPORTS GPRS AND OTHER GSM SERVICES,SUCH AS SMS AND VOICE,SIMULTANEOUSLY </li></ul></ul><ul><ul><li>CLASS B CAN MONITOR GSM AND GPRS CHANNELS SIMULTANEOUSLY, BUT ONLY ONE SERVICE AT A TIME </li></ul></ul><ul><ul><li>HIGHER THE CLASS , THE FASTER THE UPLOAD CAPABILITIES OF A DEVICE </li></ul></ul><ul><li>3G MOBILE :A SET OF STANDARDS ALLOWS MIC ROAMING AT ENHANCED SPEED </li></ul><ul><ul><li>PACKET MODE TECHNOLOGY ALLOWS VOICE, TEXT AND MULTIMEDIA SERVICES ON ONE DEVICE </li></ul></ul><ul><ul><li>SPEED RANGING FROM 64Kbps TO 384Kbps/2Mbps </li></ul></ul>
  8. 8. HOW DOES M.I.C WORK? [ ] <ul><li>EDGE: ENHANCES GSM N/Ws AT 3G DATA RATES </li></ul><ul><ul><li>DATA RATES UPTO 384Kbps IN WIDE AREA AND UPTO 554Kbps IN LOCAL AREA </li></ul></ul><ul><li>PUBLIC ACCESS WLANs: CONNECTED TO INTERNET VIA A WIRED TECHNOLOGY CONNECTION </li></ul><ul><ul><li>RANGE AROUND 100 MTRS, DATA RATES MORE THAN 4 TIMES OF 3G N/W </li></ul></ul><ul><ul><li>LINKED PUBLIC ACCESS WLAN: BY OVERLAPPING THE WLAN CELLS TO BUILD LARGER WLANs </li></ul></ul>
  9. 9. ADVANTAGES COMPARED TO FIXED LINE INTERNET CONNECTIVITY [ ] <ul><ul><li>PORTABILITY OF DEVICES AND SERVICES </li></ul></ul><ul><ul><li>OFFERS A HIGH DEGREE OF COMPATIBILITY AND INTER-OPERABILITY WITH SERVICES </li></ul></ul><ul><ul><li>USERS CAN ACCESS THEIR INTRANET AND MAIL SERVICES WHEN AWAY FROM THEIR INSTITUTION </li></ul></ul>
  10. 10. DISADVANTAGES COMPARED TO FIXED LINE INTERNET CONNECTIVITY [ ] <ul><ul><li>DUE TO PORTABILITY OF DEVICES, AVAILABILITY OF INFORMATION ON SCREEN IS LESS </li></ul></ul><ul><ul><li>SLOWER DOWNLOADIND AND UPLOADING DATA RATES </li></ul></ul><ul><ul><li>DATA RATES DECREASES AS THE DISTANCE FROM BASE STATION INCREASES </li></ul></ul><ul><ul><li>RELIABILITY OF ACCESS IN RURAL AND MOUNTAIN REGIONS </li></ul></ul><ul><ul><li>EXPENSIVE EQUIPMENTS </li></ul></ul>
  11. 11. <ul><ul><li>DEVICES ARE NOT ALWAYS COMPATIBLE WITH DEVICES USING DIFFERENT MIC TECHNOLOGY </li></ul></ul><ul><ul><li>MORE EXPENSIVE THAN FIXED NETWORK INTERNET CONNECTIVITY </li></ul></ul><ul><ul><li>NETWORK SECURITY </li></ul></ul><ul><ul><li>SECURITY OF DEVICES AND THE DATA THEY CONTAIN </li></ul></ul>[ ]
  12. 12. [ ] <ul><li>ISSUES IN CONTRACTS AND EQUIPMENTS </li></ul><ul><li>COST OF ACCESS DEVICES AND SUBSCRIPTIONS </li></ul><ul><li>COMMERCIALLY AVAILABILITY OF TECHNOLOGIES </li></ul><ul><li>N/W DATA RATES </li></ul><ul><li>N/W RANGE AND COVERAGE </li></ul><ul><li>DEVICES </li></ul><ul><li>PRICE </li></ul><ul><li>NETWORK SERVICE PROVIDER </li></ul><ul><li>SECURITY </li></ul><ul><li>COMPATIBILITY ISSUES </li></ul><ul><li>REMOTE ACCESS </li></ul><ul><li>SUPPORT </li></ul><ul><li>TRAINING </li></ul><ul><li>BATTERY LIFE </li></ul>
  13. 13. IMPLEMENTAION ISSUES [ ] <ul><li>ISSUES FOR INDIVIDUAL </li></ul><ul><ul><li>TERIFF FOR USER NEEDS </li></ul></ul><ul><ul><li>SUITABLE ACCESS DEVICE </li></ul></ul><ul><li>ISSUES FOR THE INSTITUTION </li></ul><ul><ul><li>NETWORK CHOICE </li></ul></ul><ul><ul><li>COMPATIBILITY </li></ul></ul><ul><ul><li>REMOTE ACCESS </li></ul></ul>
