Next Ge�exat�au Netwark Plan <br />Yage 9 <br />C'�'�'s design and cost estimate suggests that the initial �nvestzxient for a WiFi network to <br />provide co�eiag� in each NSCC city is over $9 ��11ifl� (Table 20), not including <br />consumer equipment costs and operational and mainte�ance expenses. The clear <br />alternative �- contracting US Internet to expand its Minneapolis model to cities within the <br />NSCC as additional anchor tenants — also entails a comparable financial commitment, but <br />with lower control of service availability and performance. <br />The cost per household and business to deploy a WiFi network is directly proportional to <br />the density a� households and businesses. On a collective basis, the one-time cost per <br />�qusehoId/business is under $200. The results on a city-by-city base vary widely. <br />It's also significant to note that the Ne�t Generation Network proposed herein will <br />support and enhance any future wireless deployment. W��i's � �c r Fc7r:n�ntc �� is <br />dramatically enhanced with the addition of fiber. Without fiber access, WiFi is usually <br />"backhauled" over wireless technology that is often limited to data rates of 1pZVLbps and <br />requires a line-of-sight to maintain connectivity. Fiber enables backi3au�. transfer rates of <br />100 Mbps at lower cost -- and is less vulnerable to interference, eliminates seasonal <br />variations in performance, and eliminates a potential traffic bottleneck. <br />With the fiber NGN as the core of the network, the cities may wish to cautiously consider <br />additional deployment of a regional wireless network This network's feasibility would <br />be enhanced by the cities' collective buying power and range of population densities. In <br />2006, CTC conducted a feasibility study for St. Anthony Village on the potential for <br />municipal wireless Internet and determined that it was limited by its low population <br />numbers — the business model did not work given the need to spread fixed operational <br />costs over a small number of subscribers. A collective or collaborative approach among <br />all the NSCC cities would expand that pool of potential subscribers and offer greater <br />economies of scale to the participants. A collaborative approach would also enable <br />leverage in negotiations with the private sector and economies of scale with respect to <br />equipment, cans�:uction, operations, and services. <br />1.3 Users and Stakeholders: How Might the Network be Used? <br />Public Safety. Many of the cities view connectivity as a critical need for public safety <br />communications and anticipate rapidly increasing needs for this service. Leased circuits <br />limit the ability of the cities to prioritize traffic, maintenance, or repair of the network. <br />They do not allow public safety officials to fully calculate the availability of the network <br />and mitigate pending risks in comparison to a private fiber optic netwark. <br />A comprehensive network with connectivity between cities and the County enables <br />redundant connectivity for public safety radio stations and mobile broadband access in t <br />vehicles. It could enable interoperable communications among multiple public safety ,� <br />4 <br />'i Examples of targeted deployments include downtown hot-spots, library access, school yards, and public <br />gathering places. <br />all text and diagrams C�?
