Alligator Communications Model 920A
|
|
|
Alligator's 902-928 MHz ISM Band license-free
spread spectrum radio employs the latest wireless data transfer
technology to provide the most reliable and secure performance. With
over 30 user-selectable hop tables and access to over 50
frequencies, the Model 920 overcomes the interference problem
experienced by other spread spectrum radios.
|
 |
The radios can be rapidly configured
for utilization in Point-to-Point or Point-to-Multipoint applications with
the provided utility software. The quick configuration option in the
software allows multiple radios to be configured with the same setup
information without repeating through the menu selection.
Key features
-
Frequency Hopping
-
Up to 57,600 bps Full Duplex
-
Store and Forward Data Repeating
-
30 Selectable Hop Tables
-
RS232 Standard Data Interface
Implementation
The radio can also be configured as a
repeater via Store & Forward data configuration, and can effectively
extend the coverage of the radio network. To assure the integrity and
security of the data, Error Detection techniques are inherent in the
design of the radio's performance. The radio's standby or sleep modes help
conserve power where power consumption is a concern. Alligator's spread
spectrum radios are technically sophisticated yet easy to set up, and they
can be deployed quickly to save time and money.
