Faster
GSM Modem Speeds with SMS over GPRS
Document ID:
TB-NOWSMS-006, Last Update: February 10, 2003
With the v4.11
release of the Now SMS/MMS Gateway, the GSM modem
interface has been optimised to support faster
message transmission, particularly when used on
devices and networks that support SMS over GPRS.
With traditional SMS over GSM links, it was only
possible to achieve an SMS transmission speed
of 6 to 10 messages per minute, depending on network
factors. However, with SMS over GPRS, and the
v4.11 release of the Now SMS/MMS Gateway, we’ve
tested GSM modem speeds of 30 messages per minute,
or 1 message every 2 seconds, a speed that is
3 to 5 times faster than previously available
with GSM modems.
While SMS over GPRS is
still not nearly as fast as SMS speeds available
with direct SMSC connections, SMS over GPRS
does make the use of GSM/GPRS modems fast enough
for a larger variety of applications.
To support SMS over GPRS,
you require a mobile phone that can be configured
to support SMS over GPRS, and you will need
a subscription with a mobile operator that supports
SMS over GPRS. (Many mobile operators are in
the process of adding support for SMS over GPRS,
as it can be more cost effective for them to
implement on their networks.)
Our tests of 30 messages
per minute over a GSM/GPRS modem were conducted
with a SonyEricsson T68i connected to the NowSMS
gateway with a serial cable. The mobile operator
was T-Mobile in the USA. We configured the T68i
to support SMS over GPRS by selecting Connect->Data.
comm.->SMS access->GPRS.
It is anticipated that
many more devices and modems will be introduced
that support SMS over GPRS in the coming months.
Below is a list of devices of which we are currently
aware that support SMS over GPRS, with instructions
for configuring the device to support SMS over
GPRS. This should not be considered a comprehensive
list of devices supporting SMS over GPRS. Consult
the documentation for your device for additional
information, and inquire with your network operator
to determine if they support SMS over GPRS.
