In more static applications, the potential for whitespace is stronger. Another big application for SIM cards in M2M cellular modules would be in utility meters. This kind of application would be more suited to a whitespace network. It’s quite easy to imagine a utility provider rolling out a whitespace solution on a local bases in order to provide a WAN network for smart metering applications. It wouldn’t need to be a nationwide network and without the mobility requirement, network planning would be more predictable. However, again it’s my view that there would still be many challenges for whitespace here. The application is already very crowded in terms of wired and wireless solutions aimed at addressing this issue. Whitespace’s late arrival in this market, amplifies its challenges.
