Communication 4-3
GSM-Based Wireless Communication
The IETG FlowHawk monitor system supports GSM wireless
communication through a GSM/GPRS module over TCP/IP using
static IP address network services. Both the Profile software and
IntelliServe
® hosted systems support TCP/IP communication.
Wireless communications and the quality of service depend on local
conditions and service providers. An optimal location for flow
monitoring may not offer the best wireless network coverage. The
water system owner may provide a recommendation for finding the
most reliable network and network provider for the project area.
However, the user is responsible for identifying the most reliable
network for your project area. Therefore, perform a signal survey
to ensure that the monitoring site has adequate reception. Consider
consulting local government or wireless providers for assistance.
Note: Do not rely solely on coverage maps. These can
provide misleading information for specific areas.
Typically, sewer systems exist in low-lying areas in which
network access can be the most difficult to obtain.
Currently, static IP SIM cards may be used for communicating
through the Profile or Qstart software platform. Consult IETG for
specific providers that have been tested with the FlowHawk GSM
Module.
Only static IP SIM cards may be used for networks supporting
IntelliServe. This service supports Mobile Terminated service as
well as Mobile-Originated (alarm cryout) functionality.
Wireless communication with a FlowHawk begins with entering the
IP address or phone number (Modem) into the Profile or Qstart
software Location Information File (LIF). When using a SIM card
that provides a public IP address, the PC must have internet
connectivity. When using a SIM card that provides a private IP
address, the PC first must establish a VPN connection with the SIM
provider. Consult IETG for more information on using private
addresses. Refer to the Profile manual #950015 (version B4 or
