Alligator Communications Model 2020A
|
|
|
Alligator's 2.4 GHz license-free spread spectrum
radio employs the latest wireless data transfer technology to
provide the most reliable and secure performance. With over 100
user-selectable hoop tables and access to over 400 frequencies
within the same channel, the Model 2020B has overcome 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 19,200 bps Full Duplex
-
Data Repeaters
-
Over 100 Selectable Hop Tables
-
RS232 Standard Data Interface
Implementation
A network ID number is used to
identify all the radios within the network, and up to 239 radios can be
deployed within the same network. The radio can also be configured as a
repeater via a back-to-back configuration to effectively extend the
coverage of the radio network. To assure the integrity and security of the
data, Forward Error Correction techniques are inherent in the design of
the radio performance. The radio's doze mode or sleep mode help conserve
power where power consumption would be 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.
