11.1.

NB-IoT: Introduction

PCTEL is introducing a new measurement to quantify the KPI metrics of the NB-IoT

network. This application note will discuss the new features of this measurement.

11.2.

NB-IoT Physical Layer

The NB-IoT physical channels can be located as a stand-alone network or they could be

part of a standard LTE network in Guard-band and In-Band spectrum. Below is a representation
of these signals.

Figure 28 - NB-IoT

Top N NB-IoT Signal Measurement

Below is a list of key features of the new measurement.

•

The NB-IoT carrier follows the 3GPP FD-LTE channel raster. It has a channel index
value of 100 kHz. To align the NB-IoT signal with standard LTE the 3GPP standard
introduces a

frequency offset

value from the channel raster. The values of the

offset

could be 0, +/-2.5 kHz and +/- 7.5 kHz. The scanner will calculate this value as
explained below.

•

The user must select the ‘operation mode’ to determine whether the network is stand-
alone, Guard-band or In-Band.

•

When the user selects the ‘stand-alone’ they must provide the

channel

frequency

the NB-IoT network. In this mode the scanner calculates the

frequency offset

as zero.
