Capability
Widest
Range
We manufacture
the widest range of microwave transmission equipment for professional
applications. It covers analogue and digital, point to point and
point to multipoint, fixed and mobile systems at licenced and unlicenced
frequencies.
Analogue
- Point to Point - Point to Multipoint
The analogue
systems provide the highest quality with no latency (delay between
the event occurring and it being displayed). There are two point
to point options. The first transmits one or two video signals and
bi-directional telemetry over clear line of sight paths. Frequencies
are from the licence exempt 5.8 GHz band to the interference free
millimetric bands.
The second equipment
is the multichannel link, which transmits up to 19 real time videos
as well as telemetry. It is unique to Ogier and allows complete
networks to be implemented using microwave. A point to multipoint
version allows up to 15 videos to be received in any 90 degree sector.
Digital
Equipment - Mobile - Point to Multipoint
The Mobile-T
is ideal for mobile applications or where there is no line of sight.
The video quality is equivalent to digital TV. The system uses OFDM
technology employing the same DVB-T standard used by broadcasters,
which enables it to operate as effectively from reflections as direct
signals.
The 10.5 GHz
wireless IP system (see broadband) can be used to provide wide area
CCTV from hundreds of cameras over 360 degrees out to 10 km from
the base station. Its an ideal solution where commercial premises
are to be linked into a city wide CCTV network.
Benefits
of Microwave
Microwave is
simple and easy to install. In some
cases, e.g. mobile, over water, inhospitable terrain or congested
areas it can be the only solution. The
video quality is to broadcast levels, which allows multiple relays
to be employed. The
multichannel link is particularly important because only one system
is required to transmit up to 19 real time full resolution videos.
It is neater, smaller, cheaper and easier to install than conventional
microwave links. Growth potential is by plug-in modules.
Worldwide
Installations
Our microwave
networks have been installed worldwide as stand-alone systems and
with fibre optic. They are employed in cities, at military bases,
at seaports and airports and in border surveillance systems.
