Vyyo
MMDS 2.5GHz System
The SPEEDEX Vyyo system is based on
a state-of-the-art wireless cable modem. SPEEDEX
is a comlpetely wireless system operating from our advanced
broadcast station near Pelzer, Indiana. If your location
is within our coverage area (see below), click

your location to see if you can get our high speed Internet
service.

How
OVC's MMDS System Works
Our
Vyyo system uses a completely wireless MMDS (Multipoint
Microwave Distribution System) that operates in the
2.5-2.7GHz radio range, so it is unaffected by rain
or snow.
The
heart of our wireless system is our 600' radio tower
near Pelzer, Indiana on
New Hope Road. On that tower is our 2.5GHz MMDS transmitter
for wireless television and high speed Internet. Also
on the tower is an omnidirectional receiver to receive
the return signals from your cablemodem.
At
the base of our tower is our head-in where our television
and Internet equipment is located. The television signals
that we transmit to you are first received at our head-in
via satellite, or in the case of many local stations,
off the air. These signals are then processed and converted
to the proper cable television frequencies for our channels
(channels 24-54 or 220-405MHz). After the signals are
ready for transmission, they are upconverted to the
2.5-2.7GHz range, with each channel taking 6MHz.
The
receiver on your home or office then picks up this 2.5GHz
signal and downconverts it back to the 220-405MHz range
where the signal is transmitted on coaxial cable directly
to your television or cablemodem. If you're curious,
our Internet downstream currently operates on channel
49, so that's why there is no television channel there.
The
first step in determining whether or not we can provide
service is for you to request
a signal survey. What we'll do then, is send a van
to your location that is specially equipped with a 75'
collapsible radio tower. We will then raise the tower
and determine at which height we can receive an acceptable
signal.
If
we can receive signal at your location, we will let
you know and give you a quotation including antenna
height and installation options. Typically, your installation
will look like one of the below images, only mounted
on a tripod or pole above your building, and sometimes
on a tower next to your building if necessary.
The above dipole antenna is used for cable television,
and sometimes
with a cablemodem in order to boost the signal of a
standard transverter (below).

The CalAmp transverter/antenna is used with a cablemodem
for Internet access.
Shown next to a cellphone for scale, it is also sometimes
used with a dipole
(above) to boost signal. Weight: Under 6lbs. Dimensions:
Approx 1.5' Square
The Conifer transverter/antenna is used with a cablemodem
for Internet access.
