E. Van Cullens President, Harris Corp. How will microwave radio equipment evolve, and what role will it play in the local loop? Generally speaking, microwave systems provide high-speed transmission links between elements of various types of networks. Historically, these links were typically backbone connections in both public and private networks. In recent years, microwave applications for interconnecting cell sites have developed in the cellular/PCS market. More recently, microwave is being used as an access technology. Looking to the future, there are several market drivers that expand the application of microwave technologies: • The rapid, global growth of wireless and mobile communications; • The privatization and deregulation of public networks worldwide; • The use of personal computers as communications devices; • The explosion of data/IP-based traffic; and • The ever-increasing demand for higher bandwidth access. The current focus in the microwave radio market is on cost-effective solutions for service providers in any environment. Whether the subscriber is in a rural area, or in a city where there is no fiber or copper infrastructure, there is a growing market for highly reliable, rapidly available services to customers at an affordable price. Competitive carriers do not have the resources nor the time to deploy a wired infrastructure. If they are to stay in business, they need to build their networks quickly, and this is best done with wireless technology. Presently, point-to-point technology is being installed all over the world. But, the future of microwave technology is in the broadband wireless access market — driven by the development of broadband, multipoint technology and the ability of these systems to support data as well as voice protocols. The convergence of voice, data and video will be seen most clearly at the customer access level. Competition between alternative access technologies will continue to be fierce. Where speed of deployment is critical, or alternative solutions are not readily available or affordable, microwave solutions will find increasing utilization. The new broadband wireless access (point-to-multipoint) solutions employing IP architectures and optimized for data traffic will be a strong option in the business access market. Costs, bandwidth, flexibility and speed of deployment will make microwave solutions an integral part of many access networks, especially in emerging markets. Ultimately, the near-term need is to provide customer access. However, the development of next-generation products will need to focus on increased bandwidth. The development and rapid deployment of advanced, broadband, IP-oriented solutions is the future in microwave. Hiram
