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.

When was the last time you surfed the Net on your mobile phone and were limited by its small screen? Have you ever wanted to hook onto the Web but found yourself connectivity-handicapped because you were not in a hotspot? Wireless technologies of all kinds ranging from mobile phones running on 3G technologies to laptops utilising Wi-Fi facilities are fast re-shaping the way we work and play.

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.
