Greenpoint was a
mobile telephone network of the PTT Telecom (now KPN) in the Netherlands. It
started in May 1992. It was intended as a cheap alternative to the expensive
phone of Greenpoint called GreenHopper. In
the early days the name Kermit was used to Character Muppet Kermit the Frog. The
cost of the license Henson proved so high that an extension was not an option. Thus, it was
stopped by the name of Kermit.
is a so-called type 2 Cordless Telephone (CT2) system, based on the ETSI
standard I-ETS 300 131. The system works digitally. The
standard describes two types of use: private and public. The
private use is done with a mobile phone and a base station in the home. The base station is
connected to the telephone network. The
public phone function works in close proximity (150 meters) of a public base
station (TelePoint). In
the Netherlands, there were about 5,000; mainly
located in post offices, V and D's, gas stations, exhibition halls, railway
stations, restaurants and parking. At
these locations with a Green Point Station, one could call, but can not receive
calls. In order
to be still accessible, often a pager was used. Kermit was also
with built-in pager available. At
the height of its existence, in 1996, Greenpoint had 60,000 subscribers. In 1998, this
number had fallen to 20,000. Greenpoint
was terminated on January 1, 1999.
in almost all networks for public office, only the call is deployed from the
portable telephone, although the standard does indeed provide for the
possibility to call the mobile phone. Only
in France is built into the test phase of the network there, Bibop this
mobile phones were virtually anywhere on the market which were fitted with a
beeper (pager) in order to increase the accessibility of subscribers.
most successful were the CT2 systems in Hong Kong, Singapore and Canada. But
ultimately also as the CT2 networks it must pass at the end of the nineties
against GSM for mobile telephony and DECT for fixed line.
