Site Survey
It is strongly recommended that a site survey is conducted prior to in-
stallation of a DualCom GPRS to confirm that adequate GPRS signal
strength is available at the site.

Before visiting the site, call CSL Technical Support. See page 11. Ask for a
GPRS signal strength prediction. For this, you will need to have the Post Code
of the site available. This will tell you if there is GPRS radio coverage at the
proposed site.
DualCom GPRS may be supplied with a Vodafone UK SIM Card which
can only be used in UK on the Vodafone UK GSM network. Alternate SIM
Cards may be available. Call CSL Tech Support for details.
If there is no GPRS radio coverage at the proposed site, the DualCom’s GPRS
radio alarm reporting and polling path will not operate. If there is no GSM radio
coverage at the proposed site, the DualCom’s GPRS and GSM radio alarm
reporting and polling paths will not operate.
Use of the CS2366 GSM/GPRS Radio Test Set is recommended to survey the
proposed site for GSM/GPRS signal strength and to locate the point of strong-
est signal. See Aerial Siting on Page 12 for more information. Make a note of
this point and use it when installing the DualCom aerial.
DualCom recommends that a minimum of 2 base stations are available with
40% or greater signal strength on one and at lease 30% on the other.
