On Monday the BBC’s panorama programme will be looking at the possible health side effects of using WiFi across our cities, possibly prompted by the similar story in the Telegraph.
I notice that they mention that 12 cities are now completely covered by WiFi, and looking at the BT Openzone press release does this mean that Cardiff is already covered? I don't think it is...
Keeping in mind I haven’t watched it yet, am not a scientist and know very little about what happens when 802.11 networks get busy… legal WiFi kit operates at very low power outputs (0.1 watt) compared to the average mobile phone handset (of nearer 2 watts), I'm personally more worried about risks from a saturated mobile network than a busy WiFi cloud.
Anyway, if you’ve got more exciting things to do on Monday evening, an on demand webcast will be available to watch on the Beeb’s website.
