RDF: the “Radio Router”
RDF is the Remote Data Frontend
It is an Analog & Digital Data Concentrator , to fully interface any old, new and ancillary equipment
RDF provides three extraordinary powerful
features, unique to the Garda system:
Each site can be configured as a “data router”,
storing and forwarding the relevant
communication to the next site if not in site with
the former
TCP-IP connections with the control center can
be obtained using a low data rate media.
At the transmission site, the two paths (towards
the server and towards the next site) can use
different communication media, allowing
mixed communication networks de facto creating
clusters
RDF handles a number of media:
•RS232
•Ethernet
•VHF/UHF radio
•GSM dialup
•PSTN dialup
•GPRS
•CDMA
•UMTS
•Satellite

How RDF becomes a VHF/UHF “Radio Router”?
Example:
•
The RDF receives a data packet
– checks if data is for its own use,
– if not, it checks the routing pattern, and
– retransmits the selected data the next
RDF on its path
–
•
•
Large network
•
Proprietary Protocol
•
And again till the final destination.
Each RDF acts at the same time as a remote
control and a Radio Router.
A packet is routed in less than a second: it
will reach destination with many jumps in
just a few seconds.
Each RDF can connect directly to up to 12
RDF (star) and up to 255 per network
ANT uses a proprietary protocol optimized
and improved over the years on collision
detention, error recovery, etc…
Backup media
•
Should the data not pass through the Radio
channel, the RDF can switch to alternative
channels (modem, mobile phone, dedicated
router, etc).

RDF: Nr. 4 Models
Code
Description
RDF
Basic Unit
Remote Data Frontend with Ethernet Port
RDF-ETH
RDF-ETH is the ideal solution whenever you have a DSL connection and a lot
of mixed analog and digital data and controls to manage
Remote Data Frontend Light
RDF-L
RDF-L is the ideal solution whenever you have a small number of data and
controls to manage, but you don’t have a DSL connection on site; NO RS-485
interface, NO expansion possible, NO additional or backup modem possible
Remote Data Frontend Light with Ethernet Port
RDF-L-ETH
RDF-L-ETH is the ideal solution whenever you have a reduced number of
physical data and controls to manage, and you have a DSL connection on site;
NO expansion, NO additional or backup modem possible

RDF: Expansion racks
CODE
DESCRIPTION
PB-RACK
Probe Rack: for pick-up and RF probes
BS-RACK
Basic Rack: to accommodate any RS485 expansion module and any dedicated
interface board, like ANT130, ANT132, ANT137, ANT139, etc.
PW-RACK
Powered Rack: same functions as the Basic Rack with an additional redundant
power supply, when the power distributed via RS-485 is not enough to feed all
extension modules
M-RACK
Modem Rack: designed to carry GSM or CDMA backup at the broadcasting site
MPW-RACK
Modem Rack Powered: designed to carry GSM or CDMA backup at the control
center
