Determines the field strength value purely on the basis of the loss due to

Selected calculation mode affects the k-factor for the calculation (see sight

Additionally the consideration of morphological classes is possible if
available; the clutter heights of the urban and rural morphologic classes
are added to the topological heights

Procedures of Summation for Interference
Calculation
Interference Analysis
In modern Planning Tools, the cumulation of the single
interfering fields can be done in several different ways.
The various procedures differ in the way how simplifications are
used to minimize the calculation effort.
In the following a short overview is given for the procedures
which are most often used in interference calculations.

transmitter featuring the maximum signal; its field strength must exceed
the minimum field strength required for coverage, Emin equiv.

Planning Fixed BWA Networks
Example:
Case Study
Planning of Fixed Broadband Wireless Access Networks
In structure of a case study, the planning of a broadband wireless
access network in different environments will be presented.
The network design is based on real scenarios using

Scenario 1: “Rural Area”
Valley, villages
Lower average income
Lower penetration of home computers
Fewer business
No DSL via cable available, “no
competition”
Residential-dominated market
Outdoor coverage (using outdoor
antenna)
Large cell sizes
Existing core network / microwave link
for backhaul

Planning Guideline Parameters
For Scenario 1: “Rural Area”
Based on existing sites
Tx antenna height: 20m above ground
Receiver height: 2.5 / 5.0 / 9.0 m
Medium Resolution Data (25m / 50m)
based on 2 different files:
Digital Terrain Model, elevation of earthsurface
Digital Clutter Model, describing land use
above terrain
Provide no building heights

Scenario 2: “Urban Area”
Major city, high-rise buildings
Many potential broadband customers
High penetration of home computers
Many business users
Cable and/or DSL available, strong
competition
Residential & business market
Indoor coverage dominant
Small cell sizes
Extension (more capacity) of existing or
new core network necessary
