4.1) HOW MANY CHANNELS CAN BE TRANSMITTED?
When fully implemented, wireless cable operations may have as many
as 33 channels of broadcast and cable programming. This, of
course, depends on which channels are already used in your area.
Furthermore, 20 of the 33 channels are borrowed from ITFS services
and are earmarked for educational use. This means there is a
requirement to program 20 hours per week per channel of
educational material. All educational programming is now allowed
to be placed on one ITFS channel instead of having it spread over
the four channels in the ITFS group. For new ITFS licenses, only
12 hours per week per channel is required, but they cannot be
grouped together. If any of these channels are being used, then
any extra time can be leased by the MMDS station, if the owner of
the license agrees.
Approximately 150 to 300 channels may become available if digital
compression is used. There are a few sites that are testing this
new technology, and I have heard that the video and audio signals
are quite good. They are using Zenith's new 16-level digital
transmission system which is also capable of delivering HDTV (High
Definition Television).
Also, since the signals will be sent digitally, it is expected
that the range of the signal will increase by approximately 3
times.
