However, coverage at this frequency would require a lot of very expensive base stations. For initial buildout, 40 GHz has the advantages of both lower cost per base station and a larger cell radius, reducing the total number of base stations needed. Available frequency and plans to use frequencies that are regulated in different ways or that are unregulated will have a significant effect on the speed of deployment and the total cost of each of these competing technologies. 49.2.3 Competition The future of cellular telephone technology, including CDMA, is very dependent on the development of competition using Wi-Fi, and there are some major players in the game. Intel has announced Project Rainbow, an initiative to build a cooperative venture among major IT industry companies to deploy a public Wi-Fi network nationwide. One counterproposal has been floated by Andrew Seybold. He suggests that Qual- comm should form a consortium to expand 3G CDMA data service deployment with multiple cellular providers. In an unproven market for data services, both would be risky ventures. At this point, we would surmise that if wireless high-speed Internet ac- cess becomes popular for use by stationary customers (a sort of Internet WLL), then it is more likely to be Wi-Fi than cellular because Wi-Fi has a higher bandwidth capacity for this purpose. The best way to provide mobile users with high-speed data access in the 4G range remains to be seen. Sprint, even while rolling out its national 3G network, is hesitant to invest in 4G data services because the average revenue per user of $30 is too low to make the ser- vice profitable. Voice service averages $40 per user and is much cheaper to provide. In the current economy and competitive situation, it is difficult to
