From Headend to Viewer’s TV Set |

Here’s how a wireless cable system works: |
|
|
|
1. The cable studio, along with the headend, receives programming from a variety of sources (see below). Each source is assigned a channel number, processed to improve quality, encoded, and then sent to a transmitter. The signal is broadcast in the Super High Frequency (SHF) range. Using an omni-directional transmit pattern, the signal reaches subscribers located up to 50 KM from the antenna, depending on the terrain and transmit power. |
|
|
|
2. Wireless cable signals are received by the subscriber’s small rooftop antenna, decoded (pay TV) and down-converted to standard TV channels on the subscriber’s TV set. |
|
|
|
3. One of the two systems are normally used for multiple-dwellings (condo, apartment, etc.) to receive and distribute wireless TV: |
|
|
|
a. The building management pays for all units to receive the programming from a single communal antenna. This agreed fee is usually based on the number of potential viewers. |
|
|
|
b. In other buildings, a single communal antenna is installed, with each tenant subscribing separately and billed separately by the cable company. |
|
|
|
4. In all cases, deposits are paid by subscribers that cover receiver system costs, much like cable subscribers. |
