Introduction The present document is intended to specify the minimum performance characteristics and the methods of measurement for Wireless Video Links (WVL) operating in the 1,3 GHz to 50 GHz frequency band. The present document provides the necessary parameters for equipment to obtain common approval throughout Europe. It also is intended to make it easier for the frequency management authorities to find harmonized frequency allocations. Common technical specifications and harmonized frequency allocations are expected to reduce greatly the present problems of interference and illegal use. The present document is a testing standard based on spectrum utilization parameters and does not include performance characteristics that may be required by the user or requirements for interfacing equipment. In preparing the present document, much attention has been given to assure a low interference probability, while at the same time allowing a maximum flexibility and service to the end-user.

1 Scope The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document applies to terrestrial wireless digital video link equipment operating on radio frequencies above 1,3 GHz. It does not preclude any digital modulation technique, provided that the modulated signal lies within the prescribed limits. Instructions for the presentation of equipment for testing purposes are included. Electromagnetic Compatibility (EMC) requirements are covered by EN 301 489-28 (see Bibliography). ES 202 239 [8] specifies the reference receiver performance parameters, which are required for the purpose of spectrum planning and methods of investigation including resolving interference issues. These parameters play an important role in the frequency planning and the respective compatibility analysis performed by responsible national administrations. The present document contains instructions for the presentation of equipment for testing purposes. Transmitter Power limits are defined in the terms and conditions of the users operating licence. Refer to annex C for recommended frequency ranges (ERC/REC 25-10 [2] annex 2). The user categories covered, are as follows: • Category 1: typically used by broadcasters and programme-makers. Users require the highest video contribution quality and or minimum processing delay times to allow both real time inserts into programmes and easy accurate editing. These users normally operate on licensed frequencies. • Category 2: typically used by professional and business. Users have quality requirements similar to above but are maybe not concerned with delay issues that affect the broadcaster and can, therefore, operate within a smaller spectrum mask. • Category 3: typically used by industrial users. Examples include civil and industrial users, emergency services, automobile associations, the utility industries, etc, who need the good quality available from digital-based systems and who operate on licensed allocations. • Category 4: typically used by industrial users including industrial security. Most of these systems could operate either in ISM bands or frequencies specifically allocated for the purpose. • Category 5: typically used by consumers. Caters for consumers, hobbyists and amateur users. The proposed 5 MHz mask can be subdivided into 2 × 2,5 for two way visual communication and is primarily intended for indoor use.
The maximum allowable channel bandwidths for the equipment covered by the present document are shown in table 1. Table 1: Maximum allowable channel bandwidth Equipment Maximum allowable Category 1 Category 2 Category 3 Category 4 Category 5 20 MHz 10 MHz 10 MHz 10 MHz 5 MHz
