communication is controlled by the base station, or a multimaster protocol, in which any of the
radio modems can initiate data transmission when the radio channel is free.
Due to the incorporation of unique synthesizing techniques the SATELLINE-2ASxE is also suitable for
systems with several base stations using different channels. The mobile substations can easily
change the frequency for communication with the different base stations. By using this method the
coverage area of a system can be enlarged without incurring extra delays due to the capacity of the
radio channels.
The handshaking procedure of the SATELLINE-2ASxE interface is PC compatible. Most
telecommunications programs can be used with the modem in order to transmit data. This feature
together with the possibility of programming the radio data modem via the RS-232 interface (see
paragraph 7) makes SATELLINE-2ASxE a product with many application possibilities in wireless data
communication.
