21  Background
 (1) GSM-R is based on the standard Global System for Mobile Communications (GSM) platform; however, its use and deployment configurations vary to some degree from that of a public mobile telecommunications service network. These variations include an increase in the minimum quality of service and reliability, and the introduction of vehicle mobile stations which may have an increased EIRP (up to 39 dBm/200 kHz) and an increased notional antenna height (typically 4 metres).
 (2) These differences may give rise to additional co-existence considerations when other radiocommunication services are in close physical proximity. There are several European studies which deal with co-existence between GSM-R and public mobile telecommunications service networks, namely the following:
 (a) ECC Report 96;
 (b) ECC Report 146;
 (c) ECC Report 162;
 (d) CEPT Report 41.
Note: Although these studies relate to the 900 MHz band, their results also apply to the 1800 MHz band.
