RF performance tests for radiated LTE-M signaling mode

The following table shows recommended test cases for radiated LTE-M signaling mode.

Table 1. RF performance tests for radiated LTE-M signaling mode
Mode	Test item	Test specification/ID	Requirement	Note
LTE-M TX	Total Radiated Power (TRP)¹	CTIA Test Plan for Wireless Device Over-the-Air Performance v3.8.2, Radiated Power, 5.15 LTE Category M1	Undefined by CTIA for LTE-M. Operators have their own specifications for radiated performance.	For analyzing a product’s radiated performance or validating conformance with operator requirements
	Radiated spurious emissions²	ETSI EN 301 908 V11.1.7, chapter 4.2.2 Radiated emissions (UE)	30 MHz ≤f < 1000 MHz -36 dBm/100 kHz 1 GHz ≤f < 12.75 GHz -30 dBm/1 MHz	For CE certification
	Radiated spurious emissions²	FCC CFR 47 Parts 22, 24 and 27 §27.53: B12,B13 §22.905 &§22.917: B5 §24.238 & §27.53: B2, B4,B25	Versatile collection of emission limits	For FCC/ISED certification
LTE-M RX	Total Isotropic Sensitivity (TIS)³	CTIA Test Plan for Wireless Device Over-the-Air Performance v3.8.2, Receiver Performance, 6.20 LTE Category M1	Undefined by CTIA for LTE-M. Operators have their own specifications for radiated performance.	For analyzing a product’s radiated performance or validating conformance with operator requirements

Note: Radiated spurious emissions include all spurious content from the end product, for example, from Integrated Circuit (IC)s and LEDs and may differ from conducted performance.

Note: The reuse of nRF9160's FCC or ISED certificate may not be valid if the product's antenna performance differs from the performance of the antenna used in the nRF9160 certificate.
