The one-page description is a rethinking of a project proposed in 1983 to Tadiran Israel, in an effort to resolve the issues faced by infantry combatants and tanks crews on the battlefield within a city or village whereby many buildings are booby-trapped or pose an enemy danger.

1. An Infantry Combat Helmet - preliminary inquiry of the need for a
wireless intercom, and soldier location identification system, in a
Squad/Platoon level or inside troop carriers or tanks.
During my consulting assignment at Tadiran Telecom during the years 1981 to 1985 I
proposed a similar system based on very low frequency band that rides on the perimeter of
the battle field penetrates tranches and buildings. There were many technological obstacles
to overcome to gain full control of the inter-Squad or Platoon soldier communications which
I will not elaborate at this time. This one page proposal is indicative without many details.
Due to new advances in technology and exchange of e-mails with a high ranking military
official I re-evaluated the possibilities of such a system with technologies available today with
the use of digitation and photonic/infrared communication of quantum-correlated photon
pairs with digitized voice carriers. The technology was demonstrated in commercial CMOS
microelectronics and is presently an intensely researched subject since around 2003/5.
Quantum key distribution (QKD) is a secure communication method which implements a
cryptographic protocol involving components of quantum mechanics. It enables two parties
to produce a shared random secret key known only to them, which can then be used to
encrypt and decrypt messages. It is often incorrectly called quantum cryptography, as it is the
best-known. Example of a quantum cryptographic task is the DARPA Quantum network a 10-
node quantum key distribution network that has been running since 2004 in Massachusetts,
USA, and has been expanded to include a wireless link that uses quantum communications
codes. The wireless connection was installed by UK defense research company QinetiQ.
The proposed system, based on infantry guidelines of fighting war procedures within
trenches or urban areas or buildings will save lives, mostly from friendly fire or inaccurate
request of artillery support. There is a possibility that such systems already exist or where
already developed, for the military at the Squad/Platoon level and if not they should.
The proposed system will be based on 3 main principles which are (i) Squad or Platoon
soldier identification and his location on the battle field by special transponders visible to the
Company commander and above on their battle field computer screens, (ii) ability to have all
Squad or Platoon soldiers connected wirelessly to the Platoon Commander tactical radio
conversation on a listening choice (iii) ability to signal the technical failure of both systems
and possible the wounding of a Squad or Platoon soldier via the transponder which could
digitally deliver more information than the actual soldier location.
In summary the question raised are if such systems already exists, or are in development and
if the combat units are in need of such a system.
Attached are two original proposals and inquiries from my previous initiative during the 1981
to 1984 work at Tadiran Telecom of a wireless intercom within the Squad or Platoon future
combat helmet.
