Google Launches White Space Broadband Trial in Cape Town
In Conjunction With Ten Local Schools
by Karl Bode 08:40AM Tuesday Mar 26 2013
Google today announced that the company is conducting a new trial of white space broadband technology in Cape Town, South Africa. The trial will use three base stations to ten local schools, in the process both proving that interference concerns have been dramatically over-stated by opponents of the technology (read: carriers, broadcasters), while also testing Google's new white spaces database. Google is one of several companies tasked with maintaining a database that will allow white space broadband powered devices to detect and avoid nearby potential unlicensed spectrum interference. Microsoft is currently conducting a similar trial in Kenya we discussed at length last month.

Prove very little

South Africa is an entirely different beast than the US. They still use analog TV, they use DVB-T instead of ATSC, and their stations are no doubt less numerous and using different rules regarding interference, ERP, etc. This may prove it works well in South Africa, that doesn't mean it will in the US.

Re: Prove very little

I agree

But with very little wriggle room in the US thanks to deep-pocketed carrier-hired lobbyists and constituents who are happy to oblige them, Google needs hard data to fight back even if technically it's all smoke and mirrors.

would that not imply that if it works in SA, it should work better in the US? The whitespace uses the older Analog TV channels... So if those channels are a potential source of interference in SA, but we don't have those channels here in NA, it should provide cleaner spectrum... therefore if it works there, it should work here.

Re: Prove very little

It uses the space in between channels, not the old analog channels.

The old analog TV spectrum isn't empty.

After the analog shutdown, most VHF television stations in the US moved their digital broadcasts back to their original analog frequencies. The portion that they did not use was then sold off for other uses.

Privacy issues with Whitespace DB?

Has anyone brought up the potentials here? Right now, with current fixed-wireless there's no geolocation aside from what the ISP itself does. Cognitive radio tied to databases operated by Google or MS will open up a certain set of privacy issues, allowing for precise GPS-based geolocation of the CPE by whomever the dbase holder decides to market the data to.

What does it say about america...

That american companies have to go to africa to be able to test and develop these new technologies?

I find that pretty pathetic. Why aren't there trials happening here in america?
