A WEARABLE CONE of SILENCE

A non wearable Cone of Silence

So eventually viewers/followers, I the younger got my 'string can telephone' and out of frustration with it's application in the thick scrubby bush, I gave it all the toss.  Since real telephones had already been invented, why bother with a tangled string holding two can's together?
Key issue was the ridiculous physicality of it.  Having to keep the string tight, without really wrapping it around a tree or other obstacle.  Walkie Talkies were more amenable, as long as you got the basic protocol right, you could say 'over' and 'roger that' like the best of them, and emulate any kind of secret agent, pretending that your minor plastic radio was actually part of a shoe phone.  A radio at least would solve the problem of entanglement in trees, and if the frequency was low enough, the trees would not impede the signal.

Surprising then, that at the same time Agent 86 [Get Smart] kept taking his shoe off, we were also talking about shortwave radio and being asked to go learn Morse Code.  Morse code, such a simple idea, make letters out of a dit-dah rhythm, like drum beats across a wire or space.  Good that between them, Maxwell, Marconi and Morse, that encoded transmissions over radio became common place. Of course Morse code a classic Radio Teletype (RTTY), being a modulation of a tone - either ON or OFF on a wire, didn't require a lot of bandwidth [typically 150Hz] and worked well at any radio transmission frequency.

The now ubiquitous use of HTML and W3 applications on wireless devices, provides a user community expectation of the ability to interact with remote movable equipment in an intelligent manner.  Recently with the advent of low cost 2.4GHz UHF wireless systems and directional antenna's it has become possible to run SCADA systems over TCP/IP networks supported by 2.4GHz repeaters.
Providing sufficient attention is paid to the height of the towers and the use of a resilient frequency hopping spread spectrum radio. The advantage being the use of the unlicensed band, allowing the development of relatively quick solutions for a particular site. The advantage of using higher bandwidth radio is particularly attractive when the remote equipment can support interaction using higher level semantic languages based on HTML and direct these over TCP connections with a resilient frequency hopping radio layer.

The convergence of SCADA, Wireless Technology, Networking, Security, HTML technology, and intelligent remote devices is creating a rapid transformation and ability to do new and exciting things with movable equipment, assets, and people. With the advent of the vibrating iPhone, that there is now an app that would allow you to send a simple text message to a phone using an HTML5 API, which on reception at the phone becomes Morse encoded vibrations. I guess this allows for private 'vexting' [is that a new word ?] which allows a Morse savvy wearer the ability to get a message without having to read or listen to it, or to try to drag down that now well known 'cone of silence'.  HTML5 Morse Sender Application
