Environments Defining

For each environment, you define the: • • • • • • • • •

Slow Fading Standard Deviation Outdoor Fast Fading Margin Outdoor Penetration Loss Vehicular Fast Fading Margin Vehicular Penetration Loss Indoor Fast Fading Margin Indoor Penetration Loss Deep Indoor Fast Fading Margin Deep Indoor Penetration Loss

30

Subscribers Defining

Different types of subscribers using different services and equipment require different subscriber definitions. 31

Subscriber Editor • The characteristics of subscribers are defined using the nodes in the Subscriber Settings dialog box. • Possibility to create a diverse mix of subscribers by defining different services, quality types, and user equipment types and assigning them to subscriber types.

32

WCDMA Subscriber Equipment • Body loss is specified under service settings in tab Quality of Service • Radio bearers defined in network settings are listed in a tabular format • R99/HSPA/HSDPA/HSPA+ terminal category can be selected (with Ec/Nt setting defined in network setting) • All Bearers, can be individually enabled/ disabled for different equipment configurations

33

Subscribers Services

34

Subscribers Understanding Input Load

• The input load is amount traffic contributed by one subscriber from using a given service • The type of service and usage pattern determines input load per subscriber • The input load and traffic map together determine the number of active subscribers in each Monte Carlo simulation run • Input load is quantified by Erlang per subscriber and Throughput per subscriber – For packet data call, input load may be determined according to its call profile

35

Subscribers Understanding Activity Factors

• A packet data call consists a number of packet transmissions. The two consecutive packets are separated by the packet inter-arrival time. Therefore, transmission of data packets is not continuous. • From the RF point view, the radio channel is active during packet transmission, and, inactive during the packet inter-arrival time, when no packet is transmitted (although from network point of view, the user is still in active state until a timeout period is reached). • The activity factor is defined as the percentage of time when radio channel transmits on downlink/uplink. • DL and UL activity factors are used in sector throughput and interference calculation 36

Subscribers Defining DL/UL Activity Factor

• For a circuit switched voice service, the activity factor is typically 40% to 50% • For packet switched data service, the activity factor varies with applications and radio bearers used to support the service • The DL/UL activity factors in the Planet service settings should be defined according to the lowest DL/UL bearer service data rates that are allowed for the service. • The Planet analysis algorithm automatically scales activity factor when the served by a higher data rate bearer. • The asymmetry nature of the packet data service can be modeled by specifying different DL and UL activity factors

37

Subscribers Understanding Usage Weightings

• •

Subscribers in different environment may experience different radio signal fading and losses Mentum Planet defines four environment types that can be assigned individually to each clutter class The usage weightings determine the traffic distribution in different environment types

Layer Statistics Generating

61

Changing the analysis area Choosing your area of interest

Statistics will be calculated only within the region chosen in the Analysis Area drop-down menu. New areas can be created by using the Areas function under the Project Data category in Project Explorer. 62

Ignoring invalid bins Excluding null values

Depending on the type of statistics that want to be generated, it may be interesting not to include points where the layer being analyzed has no values populated. In that case, the Exclude null values checkbox can be checked. 63

Applying filters to ignore unwanted bins Selecting a grid to filter

The grid you query can be an existing analysis layer or a any other grid you have created/generated before. Remember you can use the Areas function in Mentum Planet to create grids based on existing polygons. 64

Applying filters to ignore unwanted bins Selecting a grid to filter

Enable the Apply area filter checkbox and browse for the grid (numeric or classified) on which you will be applying the filter. 65
