Communications Networks for a New Era
From: Radio Resource Magazine
This is a very Interesting Article, Disgussing where Radio and Communications are Heading in the Next Generation. I Think Ya'all will enjoy it. It's long so Please bear with Me. Thanks.
As the wireless Industry enters a decade of next generation voice and Data services, technical and economic challenges translate into new uses for Repeaters as fundamental network elements, particularly in CDMA2000 and W-CDMA networks.
Among the anticipated benefits of next gerneration services for the mobile work force are feature rich Multi-Media and Internet content services, greater network voice capacity, and high speed data services. The potential benefits are unlimited. For Example, Police and Emergency services personal will be able to transmit and recieve live video from the scene of an incident, providing decision-makers the information neccessary to organize an effective, Tactical Response. Field Technicians will have realtime access to back-offices databases, enabling them to electronicly submit work orders without wasting time filling out paperwork.
Implementation of these advanced networks, however, will also lead to new expenses-License Fees and the cost of New iffrastructure. New base stations and packet-handleing equipment must be added to accommodate this advanced environment, and leased-line cost will rise as facilities are expanded to accommodate additional capacity.
The technical challanges of offering wide area, high speed data adds to the cost of a new system. although the new technologies offer faster data rates, data throughput degrades as a user moves away from a transmission site. This meens that 3G networks require two to five times as many transmission sites as 2G networks.
Carriers also must consider the uncertainty surrounding future subscriber use of voice and data services. A Forrester research study predicts that European voice-revenue streems, for example will decline 36% by 2005. As for data, according to a study conducted by "Herschel Shosteck Associates," if operators bear the cost of providing ubiquitous high data rate coverage, "the tariffs they would have to charge for transmitting high bandwidth
would prove too onerous for end users to accept."
The studies conclussion is that a compelling business case, more so than any killer application, holds the key to profitability for 3G operators, and the use of repeaters can help achieve that Profitability.
The article goes on to Cover currant use (1.9G) and the Move to 2G and it's Good points and troubles alike, then describes what the issues surround from transitioning from 2G to 3G. then finishes with an Awsome depection of the future 3G networks. covering TDMA, CDMA, CDMA2000 W-CDMA, 3G-Hybrid systems, Urban applications, (From a technicians standpoint) the 2.5G IEEE 802.11 WLAN 2.4 Operations. Very Informative to say the least.
While they, were talking about Being able to Shoot back and fourth realtime Audio and Video from say, a crime scene, to The Tactical command Post. This has begun to reveil itself. with The New AT&T M-life cell Phones. The digital Camera Installed in these offer an incredibley High Resolution. and the price is outstanding. But when shifting to 2 and 3G systems. How to Keep the consumer prices down is the obsticle. as you and I are used to Getting Unlimited Nextel for 100.00 per month, But when applications move to 3G that same service would be expected to Jump 300%. with this happening. Everyone would drop service Immediatly, and revert to smoke signaling. So How to Keep the cost affordable, Make money in the process, and continue to Advance in Telecommunications, and RF Technology.
Thank's Ya'all for letting me Post. Have a good day
