4 Technical specifications

4.1 Environmental profile

The technical requirements of the present document apply under the environmental profile for operation of the

equipment, which shall be stated by the supplier.

The equipment shall comply with all the technical requirements of the present document at all times when operating

within the boundary limits of the required operational environmental profile.

4.2 Equipment types

4.2.1 Modulation types

The present document defines two categories of Wide Band Data Transmission equipment:

• Equipment using Frequency Hopping Spread Spectrum (FHSS) modulation.

• Equipment using other types of wide band modulation (e.g. DSSS, OFDM, etc.).

All forms of wide band modulations, other than FHSS, are treated identically with regard to the requirements of the

present document.

The supplier shall declare which modulation type(s) applies to the equipment. See also clause 5.3.1.

4.2.2 Adaptive and non-adaptive equipment

The present document covers both adaptive and non-adaptive equipment.

Adaptive equipment uses an automatic mechanism which allows the equipment to adapt automatically to its

environment by identifying frequencies that are being used by other equipment.

Non-adaptive equipment does not use such an automatic mechanism and hence are subject to certain restrictions with

respect to using the medium (see clauses 4.3.1.5 and 4.3.2.4 for Medium Utilisation factor) in order to ensure sharing

with other equipment.

Adaptive equipment may have more than one adaptive mode implemented.

Adaptive equipment is allowed to operate in a non-adaptive mode.

The equipment shall comply with the corresponding requirements in each of the modes in which it can operate.

The supplier shall declare whether the equipment is adaptive equipment or non-adaptive equipment. In case of adaptive

equipment, the supplier shall declare if more than one adaptive mode is implemented and whether the equipment can

also operate in a non-adaptive mode. See also clause 5.3.1.
