I have been working on a system that had me travel both in some parts of north coast and back again in eastern parts of Kenya. Long distance Beyond Line of Site (BLOS) radio channels have taught me that they are subjected to high levels of distortion and interference. The project involved learning and
This
impede made me revert to using one of the many MVA techniques and some bands
which could use IoT services and M2M applications to enable reliable end-to-end
data communication over HF and V/UHF radio. I also used IE on the other hand to
effectively track data transferred between the five radio stations I was
working on. The receiving station finally acknowledged all successfully
received packets and requested the sender to repeat lost packets.
I
first had to design my solution to be used in conjunction with RapidM high
performance HF and V/UHF data modems. The automatic Data Rate Change (DRC)
algorithm continuously assesses and adjust the modem data rate to optimize
throughput in the current channel conditions. There is still a lot I need to do
to have it run independently to support services and applications being
engineered almost daily. With these covid19 restrictions, I suppose ill have
all the time to delve deeper into more research and consult with my senior
engineers for a final commercial solution in coming months.
IE
and MVA can be integrated with a customer’s or system integrator’s own computer
software. At the present moment, my solution is available for Windows and Linux
to the mobile radio channel partners we have within the region and is suitable
for strategic, military, naval and industrial applications requiring reliable
data transfer via HF or V/UHF radio.
The
solution offers the following application specific interface clients in
addition to what the client’s software offers:
·
IP Data IP Client
·
HF Wireless Token Ring Protocol (WTRP)
Integration
with existing management systems is simple using the status and statistics
monitoring via the XML/TCP/IP interface. As I await AK and the ministry of IT to revise these evolving technologies,
I wish to have achieved a better solution that what I currently have; a flexible,
simple to apply for, relatively in-expensive solution that will be best suited
to work with a wide range of narrow band, low data rate IoT services and M2M
applications.
