- GSM pan European Celluar networks will operate over the whole of Europe
- eventually. There are small pilot schemes running in most EC countries,
- with Germany leading the way with two companies operating fledgling
- commercial networks. The GSM standard calls for digital encryption of the
- voice channels. Note that this is not new for Europe, the existing analogue
- system in Germany is also encrypted. I believe that when implemented the
- GSM encryption will exist from the customers handset to the mobile switch.
- Beyond the switch is the normal telecom network. PCM traffic on this network
- is not (usually) encrypted though the amount of access and expensive equipment
- needed to intercept communication on these links will be outside the capabilities of all but governments.
