Legal Issues of Ronja Tetrapolis and 10M Metropolis
- Ronja doesn't need radiocommunications licence in Czech Republic.
- Telecommunications licence is necessary in Czech Republic only
if you provide telecommunications service.
- According to an answer from Czech Telecommunication Office,
Ronja doesn't need a radiocommunications licence, because her frequency
lies outside of the Office's scope.
- The Spectrum database has
last assigned frequency at 250GHz and allows queries only up to 5000 GHz. Ronja
operates far higher than 5000 GHz.
- Ronja doesn't need radiocommunications licence in Switzerland, because
operates above 3000 GHz. "As the equipments operate within the near
infrared spectrum, they are not subject to government licensing and no spectrum
fees have to be paid (according to Art. 7 in Verordnung des Bundesrates,
,,Verordnung ueber Frequenzmanagement und Funkkonzession (FKV)'' 6. Oktober
1997, requires only the use of the frequency spectrum below 3'000 GHz a
licence)." -- Swiss Confederation, Federal Office of Communications OFCOM,
Free Space Laser Communications Systems, page 2.
- If you provide telecommunications service,
you have to notify the Telecommunications Office.
- The relevant Swiss law is
Telecommunications Law of 30 April 1997 (status on December 22, 2003).
- Art. 22 (1) at page 6 says: "Anyone wishing to use the radiocommunications
frequency spectrum must obtain a licence."
- Swiss radiocommunications spectrum ends at 1000 GHz - go to Swiss National Frequency Allocation Plan
and type From: 250 GHz, To: 500000 GHz.
- Art. 4 (2) at page 2 says: "Anyone providing a telecommunications
service in any other way must notify the Federal Office for Communicastions
(the Office) accordingly.".
- In vast majority of world's countries it is not necessary
to undergo any formalities to legally operate LED-driven visible optical
transmitting system. The divergence angle virtually eliminates any possibility
of interference with any other optical device or neighbourhood annoyance with
the distinctively visible light beam and thus no legal issues should arise
during the operation.
- The emitted beam contains no invisible radiation and it's
intensity is not harmful to the human eye at any distance. The beam lies within
band of good sensitivity of human eye and the eye iris adapts on its exposure
efficiently. This condition is fully preserved even in case of device failure
or any possible kind and/or unauthorized manipulation.
- The emitted beam poses no risk to birds and any other
animals exposed to it for whatever long time. This condition is fully
preserved even in condition of device failure of any kind and/or unauthorized
- The device is optimized for low electromagnetic radiation.
- The device is not certified for transmission of classified data.
However, eavesdropping is so difficult, obvious and confined to narrow
space, so that it is not practically feasible and unencrypted data may be
transmitted without any substantial loss of privacy.
- If the device is to be installed on places where lightning strike
hazard exists, it is necessary to proceed according to local code for
outdoor aerial installations.
- The device does not contain any particular measure to suppress
lightning strike induced EMP damage to connected electronic equipment.
Installation of the device may increase the damage probability and/or
extent due to existence of additional long runs of signal cables connected
to the potential victim equipment through the device interface.
- The device poses no health risk to humans when mounted in
publicly accessible places as it contains voltages that are not lethal even
under severe atmospherical conditions, unauthorized tampering, and any possible
- The device contains no hazardous chemicals that could release and thus
damage a person or the ecosystem.
- The device radiates no ionizing radiation even under worst-case
failure and contains no radioactive materials.
