The M-Comm is a fully intrinsically safe, wire-guided
low frequency inductive communication system, ideal
for pipeline and tunnel environments.
It consists of
any number of tough water-resistant handsets, which
achieve simplex push-to-talk communications. The
wire is low cost and can be extended up to 5km and
still achieve effective transmission. Once the wire is
extended, handsets can be coupled and used at any
point along its length.
