Forward-Thinking Digital Imagining

1) HSMM capabilities at least in the 70cm band and even in 1.25m band.

2 ) Long range HSMM networks with data/video/voice capabilities. (With products like the Ubiquiti Networks Bullet [ubnt.com] should be able to get some decent range)

3) Low-cost Digital Interface that can plug into any radio with a data port (most new radios have a data port present, plus by regulation {at least for Part 90 equipment} they have to be able to handle at least 4k8 baud data – definitely not high speed, but it lets messaging take place).

4) Compact Rapid Deployment Links (RaDL) based on Asterisk that can be quickly delivered to any location thus providing phone and radio connectivity. ** Come up with a way to do it with the Gumstix Overo boards everything could fit in a radio. Add a Ethernet pigtail on the back of the radio one would have access to local SIP/IAX2 phone capabilities plus the radio could provide long-haul capabilities for at least one call to the outside world. Instant dispatch capabilities with the package too, along with intertie to other radio systems.**

The radio itself would work as a link/remote base anyone in the local network could connect through the LAN/wLAN to the RF side to transmit/receive via the radio itself. Plus they would still have local network capabilities. Since the original gumstix/Asterisk package was able to handle 10 to 15 calls, the new package should be able to increase that by at least to 15 to 20 calls.  Attach another wLAN to the RaDL would create another sub-network as well as capability for a second RF Gateway channel.

DARN is near

The Digital Analog Radio Network is near.

DARN defined as “to mend by weaving thread across a gap” that is what is being done. Those that want to see flexibility will go with the DARN approach, as a improvement while there will be others that find it to be just annoyance. DARN definitely fits the new Digital Analog Radio Networks.

Sometimes logic can indeed be simple (send in most potentially linkable exchange).

Dual Repeater Package

Dual Repeater Package – The Maxon SM6000 Series have a built-in single channel repeater controller, here is a drawing that illustrates how two repeaters can be configured along with some of the options. (Click image to expand)

Dynamic Paths

Just like other living things there are good and bad times for dynamic paths that are taken.

One can opt to be static yet knowing dynamic paths will move you.

Be flexible with the methods that are used, yet maintain the basic standards that allow a incident operation to be conducted safely. Standards which remain static can be used as a basis for operation integrity and also represent a road map to a successful mission.

Standard Operation Procedures provide the static portion for operational planning yet they should also be dynamic so that when new methods are presented they can be placed into the Standard Operation Procedures as soon as possible.

Every situation, every incident is different, thus the need for being dynamic in operational style. At times incidents will take place that are not amongst the normal operational situations. This indeed is one of the times that we need to be dynamic in readiness and response.

Flexibility is a key ingredient to readiness and the “all hazard” approach to emergency response and planning.

As a organization which path are you opting for: static or dynamic flexibility?
