Advanced ATSC Solutions:

Single Frequency Networking in ATSC
The Advantages and Benefits of Single Frequency Networking
Single Tx’s vs. Multiple Tx’s Reasoning:
The necessity of providing quality service to large areas can’t always be fulfilled with
the simple increase in power of a single transmitter. There is a great chance of
saturating the nearby receivers. There is also the difficulty of keeping the transmission
within the contour area, or without interfering with transmission in the space that
belongs to other broadcasters.
-The cost of a single high power transmitter (often with a redundant price) can be
broken down across several lower power stations, maintaining and improving
redundancy and optimizing coverage with a gradual investment.

Advantages:
- Better use of the frequency spectrum allowing growth for TV channels.
- Uniform distribution of radiated power Distribution increases system
availability and reliability. The presence of multiple transmission points
gives the receiver an Additive Gain- addition of multiple signals- and a
Statistic Gain- for more uniform coverage.

Single Frequency Network – defined as:
Multiple transmitters operating on the same channel

Gap Filler
What characterizes an SFN?
- Synchronized transmitted signals (or with a precise delay control)
- Channel carrier frequencies with no more than ±1 Hz deviation
- Same content transmission (same BTS feeding all transmitters)

1kW Transmitters
No content conflict
The main parameters that influence a SFN, besides transmitter power
are:
•Guard Interval (GI)
•Delay adjustment
