The world is kept on changing, especially in telecommunication. In the early 90’s we were shocked by electronic mail that are free and faster then ordinary land mail. Then lately phone are growing as well, operating system for gadgets such as RIM (Royal in Motion), Android, Symbian, etc. But basically most of them run in GPRS, Edge, or 3G/3,5G network, now we’re shocked again with 4G network, new improvement of 3.5G network.

4G technology using the WiMax standard will enhance the global business world. Imagine if we could watch TV and video on mobile phones without halting. Financial transactions such as transfers and payments for purchase of goods or services can use a gadget phone. The flexibility and 24/7 connection would very handy and enhance productivity.

3G wireless seems to be all about new technology, multibillion-dollar expansions and high-wire international finance deals with little or no discussion of service offerings or value propositions. Surely investors know what this could lead to, so why is most of the wireless world making this huge bet on 3G?
One important motivation: 3G is more efficient and simply works better. Since it is packet-based it uses wireless spectrum more efficiently than first- or second-generation systems. This is particularly important for data communications because of the discontinuous and bursty nature of the traffic. Secondly, a packet-based system can send and receive messages (and calls) simultaneously from two or more cell sites while 2G systems choose the “best” site and stay locked on it until the signal is handed off. The packet-by-packet approach provides more reliable and better quality communications by a statistical hedging process similar to the portfolio theory of stock market investing. (more…)

While incremental changes to router technology have made them faster, denser (number of interfaces) and generally more efficient, the router’s basic monolithic architecture, in which a single processor performs all routing calculations, hasn’t changed. This has become more of a hindrance than a help to carriers, ISPs and enterprises looking to extend the reach of their networks while having to cut capital and operations costs.
Because monolithic routers only support a single routed network, large numbers of routers must be deployed in any location servicing multiple customers, networks or network services. Virtual routers attempt to solve this scalability problem using software to share a single route processor among multiple customers, but this approach is wrought with potential hazards and still contains the monolithic route-processing architecture that is the underlying problem.

In mobile wireless, there’s one inescapable truth: spectrum is finite. Couple that with a shift in Wall Street’s expectations and ongoing growth in minutes of use in voice and data, and the drive to maximize existing infrastructure is essential.

Pressure continues to mount as operators begin offering data services, a market the Strategis Group projects will have a penetration rate of nearly 60 percent by 2007. AT&T’s launch of GSM/GPRS data services and partnership with Cingular to build an overlay GSM network atop its TDMA network will likely be a big mover. CDMA carriers like Verizon and Bell Canada have launched their 1XRTT data networks, and Sprint PCS is not far behind.

Even moves like the FCC’s spectrum cap lift from 45 MHz to 55 MHz are a quick fix; data services will eat up spectrum quickly. While building more base stations is the easy answer, the realities of cost and zoning issues are forcing carriers to examine new alternatives.

U.S. service providers looking to keep consumers online long enough to sop up excess network bandwidth might follow the example of British Telecom, which is testing its luck with online gambling.

BT’s AOL-like openworld service, which already runs sites on music, games, travel and shopping, among other things, now offers a sports and betting online service. Operated in partnerships with casino operators from Las Vegas and the Isle of Man, the “Sport & Bets” site has sections devoted to casinos, sports betting, lottery and bingo.

“Betting, games and music are a accepted as being the three biggest mass market subscription revenue generators outside, of adult services,” says BTopenworld executive John Raczka. “We have already established leading games and music destination sites in the U.K., and we will soon have a unrivaled offering as an ISP across all three categories.”
