How Google's wireless service could push down everyone's cellphone bill

Google is getting into the wireless business, and that might mean cheaper wireless service for all of us. Google isn't building its own cellular towers -- that would be way too expensive. Instead, Google will purchase capacity from other wireless carriers and resell it as a Google-branded service. The new service might launch before the end of April.

By seamlessly combining expensive cellular service with cheap Wi-Fi, Google is expected to offer a service that's a lot cheaper than conventional wireless plans. Google wouldn't be the first to use this technique -- it was pioneered by a startup called Republic Wireless -- but a Google service would help to push the concept into the mainstream. And that will put pressure on wireless providers to cut their prices.
