Evolution of mobile communication systems over the years

2G 1G 3G 4G DIFFERENT 5G generations Of mobile Communication Systems MOBILE COMMUNICATION It's a public or private communication network that doesn't require any physical connection to establish communication between two entities. Various multiple access schemes used for establishing a wireless communication include. TDMA FDMA CDMA WCDMA * Types of Mobile 5G 4G Communication 3G 2G 1G System IST GENERATION 2ND GENERATION 3RD GENERATION 4TH GENERATION 5THGENERATION 1st Generation (1G) * Analog telecommunication standards were used in 1G network and the radio signals used on 1G for transmission are analog. R In 1G, a voice call is modulated to a higher frequency above 150MHzto connect the two different radio towers. Technologies FDMA NMT AMPS Frequency Division Multiple Access Nordic Mobile Advanced Mobile Phone System Telephone Drawbacks: O Less secure due to poor encryption algorithm. Prone to Distortions Not adaptable to latest communication standards 2nd Generation (2G) ( 1 The radio signals that set up communication on 2G cellular networks are digital. In 1991, the first ever 2G cellular network was commercially launched using the GSM standards in Finland by Radiolinja. Technologies: TDMA CDMA Drawbacks: Weaker digital signal Angular decay curve Reduced range of sound 3rd Generation (3G) * This 3G networks support services that transfers an information at the rate of a minimum 200 kbit/s. * 3G technology has included faster data-transmission speeds, high network capacity and improved network services. Technologies: WCDMA CDMA 2000 UMTS, EDGE Drawbacks: High Band width requirement High spectrum licensing fee Huge Capital. Features: Phone calls Send/Receive large email services High speed web Video Conferencing GPS 4th Generation (4G) * 4G technology, an advanced cellular technology thatallows the users to stream high quali- ty audio/video over end to end Internet Protocol. R It functions 4 to 10 times faster than the current 3G networks. * Technical requirements of 4G include all-IP packet switched network and a channel with a scalable bandwidth of up to 40 MHz. Technologies: UMTS OFDM SDR TD-SCDMA MIMO WIMAX Drawbacks: It would cost more for the 4G technology users due to poorer battery life and the processors of the device must be changed at regular times. The connectivity is limited up to few major cities and urban towns. Features: A spectrally efficient system High Network Capacity Huge data transfer rate High quality service Security and privacy A Brief Timeline of Mobile Communication Systems Core Network PSTN, Packet Network PSTN PSTN Packet Network Packet Network Internet Multiplexing TDMA, CDMA TDMA, CDMA CDMA, WCDMA FDMA CDMA OFDM Data Bandwidth 19Kbps 14.4Kbps 384Kbps 2Mbps 1-3 Mbps 200 Mbps Standards / Technologies AMPS, NMT, TACS TDMA, CDMA CDMA2000 AXRTT, EVDO) UMTS, EDGE Digital Broadband Packet Data HSPA WiMax LTE Wi-Fi Service Analog Data Packet Data Digital Narrow band circuit data Digital Broadband Packet Data Packet Data Digital Broadband Packet, All IP, Very high throughput Now (Transitioning to 4G) Time period 1970 - 1980 1990 to 2000 2001-2004 2004-2005 2006 - 2010 Technology 1G 2G 2.5G 3G 3.5G 4G Worldwide Web Using Mobile Statistics There were more than 6.8 billion mobile subscriptions worldwide in the year 2012. From the year 2007, the total number of 3G subscribers using WCDMA and CDMA2000 has increased by 45%. The total number of mobile web users worldwide at the end of 2012 is 2.1 billion. In the year 2011, more than 85% of new handsets owners have accessed mobile web through their mobile phones. The most popular mobile browser based on the number web pages visited is Opera with 21.9%. In Kenya, more than 99% of online users access internet through their mobiles.
