Multi-port modem pools use individual modem modules for each port and can be fitted with different modules. The most common choices are the Wavecom Q2303, Q2403 and Q24Plus GSM modules but there are also modem pools with 3G modules on the market.
For GSM networks the Q24Plus is the best choice. This modem module is more expensive than the Q2303 and Q2403 modules but is quad band, and therefore usable on almost all GSM networks in the world. The Q24Plus is of a newer design, more reliable and has fewer incompatibilities with GSM networks.
Ordering and first impressions
The USB 8-Port GSM/GPRS Modem Pool we tested was bought directly from the manufacturer in China. It was delivered within a week, complete with a driver CD, 8 antenna’s, a power cable and a USB cable. It is not necessary to buy directly from the manufacturer, multi-port modem pools can also be found on eBay (search for ‘GSM modem pool’).
The modem pool is a compact box with 8 GSM modules that can be replaced without opening the whole device. Each GSM module has slots for both a large or a small SIM card, a connection for an external antenna, an audio connection and an individual on/off switch. The USB connection is on the left and the power cable and main on/off switch is located on the righ
