Introduction
Yealink DECT repeater RT20 is designed in accordance with Digital
Enhanced Cordless Telecommunication (DECT) standard. It can be
deployed to extend the range of the W52P/W56P IP DECT phone to cover
areas where reception was previously not available. All the usual handset
functions are supported by the base station in the extended radio range.
The repeater, base station and cordless handset employ wireless
connection. Signals are exchanged without acoustical and visual
differences.
To connect the power for the repeater:

DECT Repeater RT20 User Guide
Multiple Repeaters
Up to 5 repeaters can be registered to one base station to extend available
reception range for all registered handsets. All repeaters must be installed
within the base station coverage area (up to 300m in unobstructed outdoor
areas and up to 50m inside buildings), as shown in the figure below. It is
not possible to install the repeaters in series or “daisy-chain”.
If the repeater is placed correctly (overlapping the coverage area of the base
station), the handsets can move freely within the total coverage area while
on a call.
If the DECT link quality of RT20 is in excellent-to-good condition, you can
register up to 5 handsets to your base station and the base station can
handle a maximum of 4 calls at one time.
The repeater can be used to extend the coverage range in all directions,
allowing several floors to be covered. The automatic handover process is
seamless.

Placement
To achieve optimum performance for the repeater, it is important to find a
good location.
Here are a few tips for placing repeaters:
Choose a raised position for both the base station and repeater wherever
possible.
When positioning the repeater, avoid obstacles that can interfere with
radio transmission such as thick wall and metal structures that may be in
the coverage area between the base station and repeater.
Avoid interference from other electrical appliances such as micro-wave
ovens, Hi-Fi equipment, computers etc.
Keep a minimum of 10 meters between multiple repeaters to avoid
coverage area overlapping.
1. Hold the handset and stand near the base.
2. Make a call, and carry the handset away from the base.
3. Make a note where you start to hear noise on the line, which indicates
the signal is getting weaker.
The optimum location for the repeater is as far from the base as possible
while still maintaining a good signal, or just inside the location where the
noise became noticeable.
