The trade publication, Maritime Digitalisation and Communications, recently
published an article, Shortwave radio evolves into an IoT network, that
describes how one company is using HF frequencies to securely transmit
operational and machinery data to shore. The article explains how the
company KNL Networks uses the high-frequency band to from a mesh network
that connects shipborne radios to one another with a cellular connection.
Ships close to the coast or in port will automatically connect directly to
terrestrial cellular networks. KNL uses the network to transfer Internet of
Things (IoT) data to shore over a network that can have a range of 10,000
km.

The article notes the company is expecting a strong adoption of this
technology and for the network to rapidly grow in the next three years. A
KNL spokesman says, “We will work with industry leaders, target providers
of smart data services, build trusted partnerships and add more vendor
services. Within three years, we will be the standard for IoT connectivity.�



The point here is that amateur radio operators shouldnt get complacent
about our HF allocations. There are smart people out there thinking up ways
to use HF as well as VHF, UHF, and microwave frequencies. There was, for
example, a report recently about a company testing HF links to speed up
stock transaction information.
