2.2.7 Standard UMTS/GSM Antenna
The standard UMTS/GSM antenna is of quarter wave type (omni-directional
in the horizontal plane), with a gain of 2 dBi. The antenna is penta-band
supporting the 800/900/1800/1900/2100 MHz frequency bands. It is
attached directly to the W2x terminals via an SMA antenna connector.
2.2.8 UMTS/GSM Window Antenna
The standard UMTS/GSM antenna can be replaced with an UMTS/GSM
window antenna available as an accessory. This antenna is a penta-band
antenna operating in the 824-960 and 1710-2170 MHz frequency bands
with a gain of 2.15 dBi.
2.2.9 UMTS/GSM Roof Antenna
The standard UMTS/GSM antenna can be replaced with an UMTS/GSM
roof antenna available as an accessory. This antenna is a penta-band
antenna operating in the 824-960 and 1710-2170 MHz frequency bands
with a gain of 11 dBi with 0.5 dBi variation over specified bands.
2.2.10 SIM/USIM Interface
The W2x terminals have a plug-in SIM/USIM card connection.
