OPTICAL WIRELESS DIGITAL DATA TRANSMISSION LINKS
BOV-2M Optical
Wireless Telecommunications System
The BOV-2M optical wireless
telecommunications system can be used to provide a line of sight wireless link
for telecommunications and digital networks, with uninterrupted voice and
two-way data transfer at a rate of 2.048 Mp/s.
The connectivity of the BOV-2M E1 2 Mb/s system is via 120 Ohm UTP
cable. This cable is connected directly
in to the RJ45 socket situated in the BOV-2M E1 system interface. All data transmission is fully compliant with
the ITU G.703 standard.
Product History
The BOV-2M system has
been commercially installed for over 2 years.
It has been used to create permanent and temporary
telecommunications/data transmission channels at distances up to 1.5 km (and
beyond using relays). Our customers have
reported no technical problems during this period – including two severe
winters in
Advantages of Advanced LED
Optical Wireless Technology:
- Affordability – advanced LED optical wireless systems offer a very cost effective
alternative to fibre optic cable, microwave and laser infrared
- Reliability – advanced LED systems offer a more reliable technology than laser
infrared. Unlike laser, they can
guarantee carrier quality reliability through heavy fog, snow and rain at
the ranges specified, they are not affected by building movement or by
birds/leaves blocking the beam.
They also have a longer operational lifespan than laser. Unlike microwave, LED is not affected by
heavy rain
- Interference – Infrared systems do not cause or suffer from
radio/electromagnetic interference and multiple LED units can be installed
in the same location. Unlike spread
radio/wireless LAN or microwave, LED infrared can be beamed through very
narrow gaps between roofs, buildings and trees without interference – our
technology only requires a 30mm gap to work, making it useful in congested
towns and cities where there is limited line of sight
- Licensing – Unlike microwave, LED Infrared systems do not require spectrum
licensing and there is no need to pay annual
licensing fees
- Low Profile – Unlike microwave antennae, LED optical wireless systems are
small, compact and discrete and look just like small CCTV cameras. Sceptre is selling one of the smallest
optical wireless systems on the market, allowing for installation in
architecturally sensitive areas
- Low Maintenance – our advanced LED systems have no scheduled maintenance
- Easy Installation – optical wireless systems do not require permits to install and no
right of way permits are required.
LED optical wireless systems can be installed within 2-4 hours
using simple line of sight and complete city-wide communication networks
can be deployed in just days or weeks.
No specialist knowledge or equipment is required for installation.
- Security - IR systems offer the highest degree of security of any broadband
access technology – unlike microwave or spread radio, an infrared band
cannot be detected or hacked by instrumentation.
- Health & Safety – LED systems do not require certification for handling or operation
thanks to their use of an environmentally friendly incoherent radiation
source. Unlike laser, spread radio
or microwave, our LED system is totally safe even if used in close
proximity to people and animals – our systems have been installed in the
Capability
The BOV-2M
system will provide:
- Full Duplex data transmission
via standard interface G.703 at a rate of 2.048 Mbps
- Monitoring and control over
status of equipment and communication in operational and test modes.
Composition
The BOV-2M duplex system is composed of two BOV-2M/RJ units each consisting of:
- One Optical Switch/Modem
(MB-E1)
- One Optical Transmitter
(OI-E1)
- One Optical Receiver (OP-E1)
