I was after a very important document that I managed to find. India has begun the process of introducing fourth generation (4G) mobile wireless broadband services, even though the government has yet to finalise a date for its long-pending 3G spectrum auction.
Nexus One is a smartphone from Google that uses the Android open source mobile operating system. The device is manufactured by Taiwan’s HTC Corporation, and became available on January 5, 2010. Features of the phone include the ability to transcribe voice to text, noise cancelling dual microphones, and voice directions while driving.

Nothing much this time. Post 4G and 3.5G in my articles, I’m going to end it here on 3.75G.
3.75G, also known as High-Speed Uplink Packet Access (HSUPA), is a 3G mobile telephony protocol in the HSPA family with up-link speeds up to 5.76 Mbit/s. The name HSUPA was created by Nokia. […]
Post 4G, I was thinking what more I could write about and then… eureka, eureka… get ready for another surprise. So, you all thought it was all over after 3G and 4G haan? Tadaan… 3.5G and 3.75G. These Gs never get over do they?
Vendors and players. A market restructuring with aggressive joint ventures and new players in broadband wireless are the highlights of 4G development. The major 4G Key players are the current 3G players that invest on R&D and sources to the future of the mobile wireless. Recently, Alcatel-Lucent and Japan’s NEC Corp formed a joint venture around LTE trials.
Orthogonal Frequency-Division Multiplexing (OFDM): is a frequency-division multiplexing (FDM) scheme utilised as a digital multi-carrier modulation method. Multiple-input and multiple-output, (MIMO), is the use of multiple antennas at both the transmitter and receiver to improve communication performance.
The new year brings renewed hopes of a better world. My Christmas was rocking. Good to start the new year with something new. What new? 4G… 4G you ask? Hell yeah, jus coz third class BSNL is using Deepika Padoon-cone to promote their crappy 3G, it doesn’t have to mean that 3G’s the latest. While, all over the world 4G is the in thing, we’re still in the dinosaur age.
3G comprises several cellular access technologies. The three most common ones as of 2005 are: CDMA2000: based on 2G Code Division Multiple Access; WCDMA (UMTS): Wideband Code Division Multiple Access; and TD-SCDMA: Time-division Synchronous Code-division Multiple Access.
2.75G or EDGE (also known as Enhanced GPRS [EGPRS], or IMT Single Carrier [IMT-SC], or Enhanced Data rates for Global Evolution) is a backward-compatible digital mobile phone technology that allows improved data transmission rates as an extension on top of standard GSM. EDGE is considered a 3G radio technology and is part of ITU’s 3G definition. EDGE was deployed on GSM networks beginning in 2003- initially by Cingular (now AT&T) in the United States.
2.5G is a stepping stone between 2G and 3G cellular wireless technologies. The term “second-and-a-half generation” is used to describe 2G-systems that have implemented a packet switched domain in addition to the circuit switched domain. It does not necessarily provide faster services because bundling of timeslots is used for High Speed Circuit Switched Data services (HSCSD) as well.
