White Spaces Are No Longer Empty
Wilmington, North Carolina is the first town in America to implement a newly approved method of wireless Internet access. The White Space network will eventually allow Internet access to be available everywhere, such as rural towns in which broadband Internet companies will not lay wire. Claudville, Virginia had a White Space network during an experimental phase of testing a few years ago, because no companies would provide the area with high-speed Internet, but the Wilmington network is the first to use the new FCC-approved devices after testing.
White space is the name given to the segments of television spectrum signals that no channels currently use. This range of frequencies is lower than Wi-Fi, Bluetooth, or WiMAX. By using these low frequencies, the signal can better penetrate objects and expand over a wider area than traditional Wi-Fi. The trade-off for this wider range of service area is that the data speeds are lower than other methods of transmitting Internet access.
The city of Wilmington is currently only using the White Space network to expand Internet access in public parks, but in the future they will open up access to residents of the area who want to subscribe to the service. As the first county to fully switch to digital television, New Hanover County, where Wilmington is located, was the perfect place to begin White Space network technology.
As a new Internet service, White Space networks could be the future of public Internet connections, but it is unlikely to replace Wi-Fi in homes. The wireless Internet in your home is faster than the White Space network and provides more Internet security because, as your home network, you can protect it with a password.
White Space networks may, however, replace mobile phone providers 3G and 4G services. The speeds are comparable and White Space networks can penetrate buildings, trees, and hills much better than 3G and 4G networks can. The main obstacle White Space networks have to overcome before they become widespread and popular is portability. For now, no one can transport active White Space nodes between locations because they have to know their location in order to avoid interfering with television signals.
When scientists discover a solution for this problem, we will see a huge leap in the availability and affordability of the technology. Until then, anyone wanting to try out the new White Space network will have to travel to a Wilmington, North Carolina public park.
