zed area. This would pre- vent even an authorized employee from using the vehicle to ram a moving airplane. Far more modestly, water meters and other utility meters that are now read by hand are already being converted to wireless technology. Integrating these networks with wireless telephony, where a wireless call, once a day or once a month, will replace a visit by the meter reader, may not be far off. In all likelihood, ubiquitous wireless technology will be deployed. It will go first to ex- pensive items or to solve problems where human life or expensive losses are possible. As it is proven and manufacturing costs go down, it will become more widespread. How- ever, to what extent these systems will use CDMA remains unknown. 49.2.5 Conclusion: New ways of living a wireless life In the end, the WOW factor of wireless technology and its revenue-generating value are only small parts of the real contribution of CDMA and other wireless technologies. The real value lies not in the realm of the mind, nor in the realm of business, but in the hu- man heart. We do not primarily mean the opportunities for helping people find mates (although this is always popular and profitable), but the deeper sense of heart that refers to courage and to people's endless ability to find innovative responses to their situations, creating a new life from changing circumstances. The PAN and the wireless home network will become seamless environments that change the way we interact with our possessions. We will call out for lost keys, and they will answer us. 4 More important, cellular telephones are already changing the way we collaborate, make decisions, and take action. In Japan, people routinely share photographs of where they are with friends rather than just chatting. When shopping, we can call a family member or housemate, show what is on the shelves, and make collaborative decisions about what to buy if our fa- vorite brands are out of stock. Instead of trying to describe products, we show others what we are seeing, allowing us to c
