Thanks Greg - that makes sense. The German terminology of 'handy phone' always amuses me for some reason!
Hope to catch up soon.

Surely a cordless home phone could be described as a mobile phone?
You could have fun with this Coligulus because you would be perfecly entitled to answer no and yes to this question.
A cordless telephone (TECO), as we know it for home use, is required to have technical criteria and product definition. These prevent it from being labelled a mobile phone because
a) The technical criteria is the limited range of the wireless transmitters for the handset and base station there are two
- transmitter frequency for voice communications
- handset transmitter frequency
The handset transmitter frequency for analogue cordless was 1.632 MHz to 1.792 MHz so the cordless couldn't be used at a too greater distance from the base station.
It was therefore not possible to roam any real distance away from the base station.
b) Additionally the product definition was important for legal reasons. Cordless telephones in this category are exempt under the Wireless Telegraph Act 1949 (but see also the Radio and Telecommunications Terminal Equipment (R&TTE) Directive and Regulations).
So there is your No answer. But what about your Yes answer?
c) If the cordless telephone is manufactured with dual RF capability DECT and GSM the phone becomes a DECT Mobile and you would be right to then call it a mobile phone. Also, there is a family of GSM Standards identified as GSM Cordless Telephony Systems.
Mobile Phones have requirements under the Wireless Telegraphy Act and R&TTE Directive and Regulations.
