4.3.1.3.4 Conformance
The conformance tests for this requirement are defined in clause 5.3.4.
4.3.1.4 Hopping Frequency Separation
This requirement applies to all types of frequency hopping equipment.
4.3.1.4.1 Definition
The Hopping Frequency Separation is the frequency separation between 2 adjacent hopping frequencies.
4.3.1.4.2 Limit
4.3.1.4.2.1 Non-adaptive frequency hopping systems
The minimum Hopping Frequency Separation shall be equal to Occupied Channel Bandwidth (see clause 4.3.1.7) of a
single hop, with a minimum separation of 100 kHz.
4.3.1.4.2.2 Adaptive frequency hopping systems
The minimum Hopping Frequency Separation shall be 100 kHz.
4.3.1.4.3 Conformance
The conformance tests for this requirement are defined in clause 5.3.5.
4.3.1.5 Medium Utilisation (MU) factor
This requirement does not apply to adaptive equipment unless operating in a non-adaptive mode.
In addition, this requirement does not apply for equipment with a maximum declared RF Output power level of less
than 10 dBm e.i.r.p. or for equipment when operating in a mode where the RF Output power is less than 10 dBm e.i.r.p.
Medical devices requiring reverse compatibility with other medical devices placed on the market when earlier versions
of the present document were harmonised, are allowed to have an operating mode in which they have a Medium
Utilisation above the limit defined in clause 4.3.1.5.2.
4.3.1.5.1 Definition
The Medium Utilisation (MU) factor is a measure to quantify the amount of resources (Power and Time) used by
non-adaptive equipment. The Medium Utilisation factor is defined by the formula:
MU = (P/100 mW) × DC
where: MU is Medium Utilisation factor in %.
P is the RF output power as defined in clause 4.3.1.1.1 expressed in mW.
DC is the Duty Cycle as defined in clause 4.3.1.2.1 expressed in %.
NOTE: The equipment may have dynamic behaviour with regard to duty cycle and corresponding power level.
See clause 5.3.1 e).
4.3.1.5.2 Limit
The maximum Medium Utilisation factor for non-adaptive Frequency Hopping equipment shall be 10 %.
4.3.1.5.3 Conformance
The conformance tests for this requirement are (part of the procedure) defined in clause 5.3.2.
