Essential Guide to Wireless ISPs Chapter 1 - Introduction 1 1 Chapter 1 - Introduction This document is aimed to satisfy the needs of the Internet Service Providers industry for comprehensive information on Broadband Wireless Access (BWA). It is intended for ISPs who are looking at BWA as an alternative to traditional wire- or cable-based services, including: a. An established ISP that considers adding BWA to its infrastructure for one or more of the following reasons: Expand coverage to new customers-either in an already served area or in new areas. Provide services in rural and other areas where wireless access is the only viable option. Enhance its services portfolio to improve competitive position and increase revenues and profits. Eliminate expenses, delays and long-term commitments associated with getting access services from a third party. b. A new entrant to the rapidly evolving ISP market place wishing to benefit from the advantages of a business based on BWA. Regardless of the reasons for becoming interested in BWA, there are numerous questions that must be answered, related to various crucial issues that must be considered prior to taking the decision to invest in a BWA based network, while launching a new BWA network and throughout the life time of the network. Our staff has accumulated a large set of testimonials regarding our partners’ network build-out. What they saw related to various aspects of the network and to various types of networks. Over time, we witnessed a wide range of situations experienced by our partners: from the management decision-making process to technical and logistic activities by different types of operators: cellular, data access, ISPs and local independent telcos. Essential Guide to Wireless ISPs 1-2 We at Netronics have been working closely with global telecom and Internet operators over a long period of time. A wide range of professionals in Netronics – senior management, sales force, customer service and technical staff – have met a long list of Operators’ management, operations and technical teams. They have discussed challenges together, made errors together, fixed problems together and succeeded together. professionals have gathered years of experience and know-how, witnessing Operators’ experiences, preferences, challenges and difficulties concerning many facets of their overall network. Netronics Introduction Until now, this valuable information has not been shared in any integrated, comprehensive format. Moreover, we began to notice that different operators often faced identical challenges. Unaware of their predecessors’ experience, they often repeated the same mistakes. We have assembled all the information gathered from the field into a comprehensive format that shows the big picture while recalling the small details. This overview refers to all the aspects concerning a BWA project, from backbone interfaces, to integrated network solutions at the customer site; from the NAT location debate to management system considerations; from VoIP to billing; it discusses technology pros and cons as well as business models. This document offers you a comprehensive overview of our accumulated knowledge in order to help you understand all the important aspects of BWA and assess the project you are taking or about to take. The document has been divided by subject matter, so that you can skip to read only the areas that are relevant to you, or read its entirety - whichever fits you best. It must be emphasized that many applicable issues vary significantly among countries and even regions. These includes issues such as local regulations that affect technical considerations and issues that affect the business model such as the competitive landscape, labor costs, customers’ profile etc. You are invited to consult with our experts in order to reach the right conclusions and build the business plan that takes into account all the unique aspects of becoming a Wireless ISP in your target area. 1-3 In the meantime, a number of employees have, over time, witnessed uploads/Geographie/ wireless-isp-guide.pdf
