With the London terrorist bombings last summer, the concern of
ensuring wireless signals were able to traverse through layers of the earth became an important priority. Well, Vital Alert Technologies of the UK has partnered with Los Alamos National Laboratory in the U.S. to develop radio services which can work underground be transmitting through solid earth.
The new technology uses Very-Low Frequency (VLF) to transmit radio signals carrying compressed audio and data signals through layers of the earth and is apparently very inexpensive to build, according to the Los Alamos engineer who originally developed the technology.
