Frequency AssignmentWRAP efficiently supports assignment of frequencies and polarisation to stations and networks

All services Manual assignment Auto assignment Simplex Duplex Consider or

exclude existing assignments

Collocation InterferenceWRAP calculates all potentially dangerous frequency coincidences and their levels due to:

TX intermodulation RX intermodulation IF breakthrough Image frequency Harmonics Transmitter spectrum

mask Receiver blocking Receiver selectivity Antenna illumination EMI emittersFrequency hopping and direct sequence

spread spectrum systems are handled.

HF Planning• Planning of HF systems employing ionospheric

propagation

• WRAP uses software from the Institute for Telecommunication Sciences in the USA

• ITS HF software is accessed from within WRAP

• Properties of stations with definitions according to WRAP standards are used

– Data is transferred automatically to the ITS codes

• The standard installation of the ITS HF software can be used external to WRAP.

Point-to-Multipoint• Definition of a specific Group: MP Station

– Comprises one base station with a number of sector stations. To each of these a number of Clients is associated.

• Sector antennas have a fixed azimuth and tilt– Thus not automatically directed towards the clients.

• Client antennas are automatically directed in azimuth and tilt towards their sector station

• Traffic: Station property Number of Channels– For clients: Defines the traffic requirement of the client– For sectors: Defines the total capacity of the sector station– Total traffic load on a sector station calculated as the sum of the

number of channels for each of its associated clients.
