Introducing Network Planning, the Planning cycle and requirements.
Company strategy is considered to identify practical issues such as
coverage, implementation, additional services, ‘back haul’,
equipment, optimisation and billing.
GSM technology imposes limits, so planning has to be done within
these limits. Discussed here are the frequency spectrum, various
channel structures (such as physical, traffic and control),
reporting, timing advance, dBs, cell selection, C1 and C2
calculations, power budget and analysis.
RF Coverage (Part 1)
Mobile networks are governed by the properties of radio transmission
through the air – RF coverage. This chapter is the first of two
chapters dealing with this issue. Here we will discuss RF
propagation, various loss factors, propagation modelling, link
budgets, fading, multipath loss and diversity techniques such as
RF Coverage (Part 2)
Continuing the subject of RF coverage, this chapter will discuss
frequency hopping, time diversity, interference, power control, DTX,
planning rollout and coverage. Various antenna types are introduced,
as well as fibre distribution links. The chapter closes with a look
at the transmitter and receiver chains.
Implementation Planning (Part 1)
Again, this subject covers two chapters. In this first part the
issue of cell sizing is considered. This starts with traffic
engineering and grade of service (GoS). At this point there is an
exercise in traffic calculation. Traffic patterns are discussed,
leading on to cell and network sizing. The three cell sizes are
defined. The chapter ends by introducing network planning tools and
transmission drive testing.
Implementation Planning (Part 2)
In this part we deal with frequency allocation and re-use patterns.
Also covered are capacity issues, backhaul, the A-bis interface and
E1 (2.048Mbps) structure. There is an exercise on ‘backhaul’ and a
mention of physical site selection constraints.
Optimisation and Statistics
Covers cell identification, BSIC, control channels, capacity
enhancement, multilayering, the use of microcells, concentric and
extended range cells, congestion relief, frequency hopping and
This introduces HSCSD, GPRS, EDGE, GERAN, UMTS, CDMA and VoIP.
