Broadband Fixed Wireless Access Adjacent Region Co-channel Co-ordination Tool Compliance Statement

The following is a tick list of both essential and "nice to have" attributes that the desired tool should comply with.

1. Essential

1.1 Models

	Needs to support the relevant 28 and 40 GHz ITU-R propagation/interference/rain models.
	Needs to be able to import new ITU-R propagation/interference/rain models.
	Needs to support a UK terrain data model.

1.2 Antenna

	Needs to support the import of antenna RPE (standard and actual).
	Antenna gain.
	Antenna height above ground level.
	The pointing angle of the antenna needs to be specified in azimuth and elevation to an accuracy of ± X° .
	The antenna down-tilt needs to be specified to an accuracy of ± Y°.

1.3 Terminal Station/Mesh Node

	Station/node location using NGR
	Power at the antenna port.

1.4 Base station

	Station location using NGR
	Power at the antenna port.

1.5 UK Licence Region

Definition of a region boundary within the UK needs to be supported.

1.6 Coverage within Region

	Station/node coverage needs to be plotted as selectable pfd contour (dBW/MHz/m2).
	Region boundary should have an assigned pfd limit. An indication of where a pfd contour breaches the boundary limit should be given.

1.7 Resolution

Needs to support a resolution down to 50m.

1.8 General

	The tool should be able to import the technical licensing data from the Radiocommunications Unified Licensing Executive Systems (RULES) database (supported formats of data to be imported).
	The tool should be able (licensed) to be run from Agency laptops.

1.9 Support

General maintenance/updates, technical support and training for use of the tool.

2. Nice to have

2.1 Models

	Needs to be able to import a UK generic (cf fixed link data) rain model (supported formats of data to be imported).
	Needs to support import and overlay of 28 and 40 GHz clutter data models (buildings, foliage, etc) for areas under interest.

2.2 Antenna

Needs to support location of multiple antennas (sectored/Mesh) at a station/node site.

2.3 UK Licence Region

	Definition of multiple region boundaries, up to 20, needs to be supported – worst case is likely to be a region (say, within M25 boundary) with four other incident boundaries.
	Within each licence region the definition of up to three (adjacent channel) BFWA networks need to be supported. These networks may have overlapping/incident network service areas.

2.4 Coverage within Region

Station/node coverage needs to be plotted as multiple selectable pfd contours (dBW/MHz/m2).

2.5 Resolution

Needs to support a resolution down to 10m.
