Its not a long ago when we were obsessed with the 3G technology. But the speed with which technology is changing, I think Human nature is changing with the same pace too. Moreover, there is nothing wrong in demanding more and more if you have got ways to meet that demand.
Yesterday was all about 3G but tomorrow is going to be a 4G for sure. Most of us all still unaware of what 4G is. So let me take you for a short trip to the world of 4G ……
4G is high-speed wireless connectivity that enables a real-time multimedia experience. It allows mobile users to not just send and receive emails, but to deal with large file transfers, view high-resolution streaming multimedia or have a high-quality interactive video experience
4G promises a world where high-quality video meetings can take place on demand, regardless of where the participants are located or whether they are in motion (e.g. in a taxi). Since tele-presence is a two-way application, upload performance is just as important as download speeds. Historically, 3G technologies were designed primarily for downlink performance, which is fine for broadcasting from a central point but not for high-speed peer-to-peer communications.
ü Smooth and Unified Communication-To date, end users with internet accounts (e.g. Skype) who have wanted to avoid international long-distance and cellular roaming charges by using a Wi-Fi ,4G changes the game by providing sufficient network performance for a mobile device to act as a fully enabled telephone . Its functionality could include a corporate phone number, email and corporate blogs, social networks and other emerging aspects of a unified communications system
ü In a 4G world, where bandwidth and latency are removed as issues, video content can for the first time be economically delivered to mobile devices.
ü 4G attempts to create the richness of a physical face-to-face meeting over a telecommunications network.
2 main features of 4G:
Two technologies comprise the anticipated fourth-generation of mobile wireless technology:
WiMAX – It delivers wireless broadband data at up to 70 Mbps in each direction. This technology is already standardized and in use in more than 300 networks. It is backed by a consortium of companies that include Intel, Motorola, Google, Sprint Nextel and major cable operators.
Long Term Evolution (LTE) is an extension to two key 3G technologies, GSM and UMTS. LTE is being backed by leading telecommunications companies that include AT&T, Verizon, Vodafone, T-Mobile, NTT DOCOMO. While LTE is not yet standardized, tests with pre-standard equipment have delivered peak speeds of over 100 Mbps.
I will be discussing one my one both WiMax and LTE in my upcoming posts but if you have a question about which technology will win out. Here is the answer:
It is unlikely that one technology will win outright in the global marketplace, and predictions of long-term market share vary widely. I believe that mobile WiMAX and LTE will each succeed, dominating different regions and competing vibrantly in some as well.
Because LTE is a natural evolution of GSM, it will eventually replace 3G technologies in those areas of the world where operators have a large and lucrative user base—primarily in Europe.
WiMAX, on the other hand, has great potential in developing markets where there is little or no mobile data infrastructure to leverage. Likewise, WiMAX is attractive for those who live and work in rural or hard-to-reach areas, where providers haven’t yet deployed 3G, cable, DSL or fiber. As, AT&T, an LTE adopter, has announced it will use WiMAX to provide fixed services in rural locations. Also, cable operators who have millions of subscribers and substantial bandwidth in place will look to WiMAX as a way to deliver additional services to their customers without having to build a 3G infrastructure.
