The price of the solution and the basic installation is 4000 baht.

Extending the range

External antenna can be connected to CDMA modem to increase the signal stability and range. There are two kinds of antennas available: omni-directional which can be used on the desktop or the car roof, and directional which can be mounted on the house exterior pointing to the CDMA tower. Directional antennas give much better range but are more expensive and require installation. You can find some antennas in our Wireless product list.
