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. 

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. 

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.  

The W2x terminals have a plug-in SIM/USIM card connection.
