What is fourth generation ( 4G ) mobile systems?:

What is fourth generation ( 4G ) mobile systems? Fourth generation mobile communications systems that are characterized by high - speed data rates at 20 to 100 M bps, suitable for high - resolution movies and television, virtual . Initial deployments are anticipated in 2006-2010 . 4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data.

4G: Anytime, Anywhere Connection Also known as ‘Mobile Broadband everywhere’:

4G: Anytime, Anywhere Connection Also known as ‘Mobile Broadband everywhere’ M A G I C M obile Multimedia Communication A nywhere , Anytime with Anyone G lobal Mobility Support I ntegrated Wireless Solution C ustomized Personal Service According to 4G Mobile Forum, by 2008 over $400 billion would be invested in 4G mobile projects.

4G: Data rate Facts:

4G: Data rate Facts Transmission at 20 Mbps 2000 times faster than mobile data rates 10 times faster than top transmission rates planned in final build out of 3G broadband mobile 10-20 times faster than standard ADSL services . Companies developing 4G technology phone companies: Alcatel, Nortel, Motorola, IT Companies: Hughes, HP, LG Electronics

KEY TECHNOLOGY :

KEY TECHNOLOGY WIMAX : WORLDWIDE INTEROPERABILITY FOR MICROWAVE ACESS WIMAX IS BASED ON OFDMA TECHNOLOGY OFDMA : ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACESS 1 MILE MOBILE BROADBAND ACESS ALTERNATIVE TO CABLE OR DSL MODEM. IEEE802.16 a AND IEEE802.20 ARE THE WIMAX STANDARDS .

WIBRO : WIRELESS BRODBAND:

WIBRO : WIRELESS BRODBAND WIBRO IS A KOREAN TECHNOLOGY 8.75 MHZ CHANNEL BANDWIDTH AROUND 30 MILES (50KM) IN FIXED STATION AND 3-10 MILES(15KM) FOR MOBILE STATION BROADBAND ACESS . IEEE 802.16 e AND IEEE802.22 ARE THE WIBRO STANDARDS .

WiMAX vs. Wi-Fi:

WiMAX vs. Wi-Fi WiMAX and Wi-Fi are somewhat independent, addressing slightly different needs. WiMAX uses private , licensed spectrum and provides Wi-Fi-like service with guaranteed performance to larger public areas, similar in coverage to cellular networks today. Wi-Fi uses shared spectrum and operates at short distances, making it ideal for low-cost, private networks (where usage of the network is constrained to an office building or campus) or free public systems (where service guarantees are not required).

The differences between the generations of wireless telecommunications:

The differences between the generations of wireless telecommunications Date & Cool Features 1G 70's to 80's Wireless phones (cellular) are introduced, primarily for voice only. 2G 90's to 2000 Increased performance achieved by allowing multiple users on a single channel. More and more cellular phones are used for data as well as voice. 2.5G 2001-2008 The Internet turns the focus towards data transmission. Enhanced multimedia and streaming video are now possible. Phones support limited web browsing. 3G 2008-2011 Enhanced multimedia and streaming video capabilities are increased. Standards are created to allow universal access and portability across different device types (Telephones, PDA's, etc.) 4G 2011+ Speeds reach up to 40 Mbps. Enhanced multimedia, streaming video, access and portability are increased still further. Devices are equipped for world-wide roaming.
