Introduction
The PFXZPBPHMC2 is categorized as a GPRS (general packet radio service). It provides a cost
effective solution for wireless remote connection to distributed installations over the Internet. It is
compatible with the mini PCIe card with SIM card holder.
GPRS is a packet-oriented data service based on GSM (global system for mobile). It offers the
advantages to pay only for the total volume of data exchanged (in MB per month) regardless of the
connection time while data communication via traditional circuit switching (PSTN/GSM) is charged
per minute of connection time.
GSM connections are used for on-demand services such as sending SMS alarms or basic remote
services such as diagnostics.
GPRS is more suitable for permanent access to remote installations providing:

Easy remote programming.

Continuous remote monitoring and control.

Transparent routing capabilities from the Internet to LAN networks or serial network devices
connected to the Slim Panel gateway.
In addition, GPRS provides higher data exchange rates than GSM:
NOTE: These values depend on your service provider, the distance between your Cellular module
and the base station, and the current traffic.
NOTE: If too many browsers are being used on a modem connection (GPRS, PSTN), performance
may decrease and lead to difficulties with page refreshing.
