4 General
4.1 Introduction
The present document defines the minimum requirements for DECT-2020 NR radio devices.
Radio channel arrangements, operating channel bandwidths and supported bands are defined in clause 5. The present
document defines operating bandwidths 1,728 MHz, 3,456 MHz and 6,912 MHz. The channel numbering scheme
enables to assign channels from 450 MHz up to 5 875 MHz band operating enabling to support up to 17 different
operating bands.
For transmitter operation the present document specifies 23 dBm, 19 dBm and 10 dBm maximum output power classes
which adapt to different type of application requirement and support battery powered use cases. The transmitter
emission masks performance meets the industry requirements. In addition, the transmitter output power can be adjusted
down to -40 dBm level, which enables the support for high equipment density use cases. The RX-TX transition time is
defined to operate within the Guard Interval (GI), which enables a very competitive low latency operation with hybrid
ARQ operation.
Receiver requirement defines the minimum performance for the radio device with hybrid ARQ support. The reference
sensitivity levels scales depending on operating bandwidths.
Measurement requirements are defined for channel access purposes and to support radio environment quality reporting.
Radio requirements testing are considered by defining reference channels such that the requirement verification is
possible with simple test.
The requirements are defined keeping in mind the state of art performance, low power consumption and competitive
implementation cost.
4.2 Relationship between minimum requirements and test
requirements
The present document provides DECT-2020 New Radio RF characteristics and minimum performance requirements.
The Minimum Requirements given in the present document make no allowance for measurement uncertainty.
Measurement uncertainties for a given requirement may be studied from ETSI TR 100 028-1 [i.1]. These test tolerances
are individually defined and
