Arctic EDGE Router

Viola Systems Ltd. 

7. GPRS and EDGE 

 

 
The Arctic EDGE Router provides a direct and reliable GPRS/EDGE connection and data 
transmission to stationary or GSM 850/900/1800/1900 mobile networks around the world.  
 
In this Chapter the specialities related to GPRS and EDGE operation are described.  

Placing Arctic EDGE Router 

 
When choosing the installation site of Arctic, please remember that it uses radio waves for data 
transmission. The surrounding environment affects the behavior of radio signals. Therefore, if you are 
using an Arctic with the antenna mounted directly to the antenna connector (without an extension 
cable), try to avoid placing the unit in a location where the radio signal might be shadowed by nearby 
obstacles. Note also that large metallic surfaces (racks) or walls with metallic structures (cabling, 
concrete iron) may highly degrade the antenna performance. In case of metal racks or surfaces it is 
recommended to use an external antenna with an appropriate cable. This allows placing of the Arctic 
more freely. 

GSM/GPRS/EDGE Antenna 

 
The Arctic EDGE Router includes a FME connector (male type) for an external antenna. It is possible 
to use any kind of external 50 

Ω

 dual-band antenna intended for GSM900 (880–960 MHz) and 

GSM1800 (also known PCN) (1710–1880 MHz) frequency bands. Connect the antenna directly to the 
connector provided for the antenna on the back panel of the Arctic unit. 
 
Typically, commercially available antennas are provided with a flexible 50 

Ω

 cable having a length of 

2–3 meters and having a female type FME-connector. 
  
The Arctic EDGE Router is tested with antennas from Hirschmann Rheinmetall Elektronik GmbH. 
Examples of tested external antennas include the following sticker-type and magnetic mount antennas 
shown below: 
 

 

MCA 18 90 STRIPE, sticker type patch 
antenna (above), and 
MCA 18 90 MH , magnetic mount antenna 
(right). Both antennas have a FME (female) 
connector and L=250 cm RG174 cable.
