Dect Deployment Assessment; Deployment Considerations; Range - Snom M700 Deployment Manual

DECT deployment assessment

DECT deployment assessment is essential to determine elements necessary to achieve the overall
expectations of the user. Typical network requirements includes (but not limited to):

The geographical area to be covered

The type or architecture of building and/or topology, etc.
This includes the material of walls, thickness of walls.

The estimated traffic in each coverage area

The blocking criteria in each coverage area.

Deployment Considerations

The following radiation related considerations must be examined before deploying a typical SNOM
M700 System. These includes (but not limited to):
Building Penetration:
When a signal strikes a building it is diffracted or absorbed; therefore to some extend the signal is
reduced. The amount of absorption is dependent of the kind of building and its environment, the
amount of solid structure. This is an important consideration in coverage planning.
Note: The structure of the building will have an impact of coverage range.
Interference Sources:
Signals from receiving antennas are weakened by interference from other signals. These signals may
be from the same network or other objects. A well planned DECT multicell installation should identify
potential interference sources for optimal placement of Base stations and repeaters.
Note: Other DECT systems or devices transmitting in similar frequencies, weakens reception.
Therefore it is recommended to set up base stations sufficiently close to each other.
Radio/Cell Range:
The suggested distance between two base stations depends on the physical path between the base
stations. If the path loss is lessened, e.g. by minimizing amount of walls/obstacles in the path, then
signals from base stations will cover more distance. In a typical office building the suggested distance
between two base stations is 20‐40m.
Note: Less obstacles between two base stations increase the possible distance between two
base stations.
