Pennsylvania Public Safety Voice and Data Radio, United States of America
The Commonwealth of Pennsylvania is in the process of installing a microwave system to interconnect its public safety voice and data radio network. As part of the project, Alcatel will provide MDR-8000 digital microwave radios, 1630 CSX digital cross connects, antennas, transmission lines and a network management system to Pennsylvania for its state-wide Public Safety Radio Project. This network will create a wireless communications system linking 22 state agencies.
Typically, microwave radio links are used to integrate a broad range of networks from fixed and mobile communications networks in rural, suburban and urban environments, to corporate and private networks. Microwave technology provides wide bandwidths for transporting crucial voice and data information where network coverage is inadequate or in need of rapid expansion.
Evolium is the brand name of a range of fixed and mobile radio solutions dedicated to ILECs, CLECs and GSM (Global System for Mobile Communication) operators and is specially designed to adapt to the constantly changing realities of fixed and cellular networks. The Evolium range of solutions includes:
- GSM Solution
- LMDS Solution
- Wireless IP (Internet Provider) Solution
- Microwave Solution
- WLL Solution
- Third Generation (3G) Mobile Solution
The system includes transmission rates from 2x2 megabits per second (Mbps) to 16x2/34 (Mbps), available in 10 microwave frequency bands (from 1.5 to 38 GHz) in both CEPT and ANSI versions. The range of available frequencies is attractive to PLMN (public land mobile network) operators who have been assigned various frequencies liberated by deregulation. Furthermore, the modular architecture of the new digital links enables both mobile and fixed operators to increase capacity and reconfigure bandwidth without changing basic hardware.
Operators of mobile cellular networks are increasingly adopting microwave radio solutions. Wireless links enable operators to build their networks quickly, so they rapidly begin generating revenue flows from subscribers. Microwave radio takes much less time to install than cable. What is more, operators can avoid long, drawn-out negotiations over cable rights of way or concessions.
Cellular operators also appreciate the fact that they can build up network capacity gradually, according to where and when subscriber traffic increases. Because of the fast, easy installation and flexibility of microwave radio links, mobile operators increasingly favour low and medium capacity links for interconnecting base stations. These are generally used in short-haul configurations, although longer distances may be involved for coverage corridors along highways or coastlines.
Fixed public networks operators, make extensive use of microwave radio links, especially in developing countries, to quickly provide or increase service in areas suffering from inadequate coverage. These include a wide range of backbone and spur applications, in all kinds of environments and over varying distances.
Likewise, private networks often rely on short-haul low and medium capacity wireless links for such applications as file and data transfer between bank branches or local offices of government agencies or services.
Long-haul low to medium capacity wireless links have traditionally been used to connect remote areas to urban centres, especially for public telephone networks. But long-haul wireless links are also becoming increasingly common in private networking environments, for example to provide transmission links with offshore oil platforms or remote construction sites.
