The technology called “cell broadcast” is currently being tested in Zoetermeer and allows authorities to send an SMS to all phones in a specific zone without the need to know each individual phone number. Hey wait, isn’t this the exact scenario that’s supposed to bring cellular networks to their knees!?Where to start? Firstly, Cell Broadcast is a standard feature of SMS, not a new technology "being tested". You'll find options for it in the messaging menu of any GSM phone. Secondly, being impressed that you can "geo-target" phones by virtue of them being in range of a particular antenna is kind of lame. And thirdly, Ricker seems unfamiliar with the concept, and indeed the dictionary definition, of "broadcasting". As you might expect, Cell Broadcast sends messages to all phones at once (using the GSM control channel), rather than having to send them separately as Ricker imagines.
