Radio Cell Planning

CELL PLANNING PROCESS

• The major activities involved in the cell planning process are shown below

Step 1 :TRAFFIC AND COVERAGE ANALYSIS

• Cell planning begins with traffic and coverage analysis
• The analysis should produce information about the geographical area and the expected capacity (traffic load).
• The types of data collected are:
• Cost
• Capacity
• Coverage
• Grade Of Service (GOS)
• Available frequencies
• Speech quality
• System growth capability

Step 1 : TRAFFIC AND COVERAGE ANALYSIS

• Traffic refers to the usage of channels, it refers to holding time of time unit.
• The basis for all cell planning is the traffic demand
• The Erlang (E) is a unit of measurement of traffic intensity
• A = n x T / 3600 Erlang
• Where,
• A = offered traffic from one or more users in the system
• n = number of calls per hour
• T = average call time in seconds
