Endrich, one of EuropeÒs design-in-house electronic

component distributor is going to present a live NB-IoT test

system on Electronica 2018 in Munich.

Networked objects such as smart devices contain a kind

of sensor and a communication module that connects them

to the Internet of Things. How can we achieve an econom-

ical, technically matching and standardized network solu-

tion – "The Right Network"?

In case of short transmission paths, local area networks

such as LAN, Wi-Fi or other WLAN solutions (Bluetooth,

ZigBee etc.), even near-field technologies can link devic-

es, but for longer ranges only LoRaWAN or mobile net-

works can be used. When data should be routed to cloud

databases and later accessed by mobile devices like lap-

tops, tablets and cellphones, existing cellular broadband

networking solutions are more convenient. However, this

technology soon reaches its limits, the traditional mobile

spectrum of a radio cell cannot be overloaded by adding

huge numbers of new non-voice subscribers (wearables,

connected cars, smart meters etc.)

Serving low data rates of usual smart devices via exist-

ing mobile broadband networks such as GPRS, UMTS or

LTE would be too expensive, the expected revolution of

M2M & IoT requires a solution with the optimal ratio of tech-

nical features and cost efficiency.

One of the technological answers of leading providers

for low power wide area networking for the M2M communi-

cations is the narrow band IoT.

It is a new cellular standard of LPWAN radio networking

technology based on existing LTE infrastructure. It offers

connectivity of a mass of simple devices within a mobile

cell, with a low data rate of 600 bits/s – 250 kbit/s as a

compromise, developed primarily for transferring small

amounts of (sensor) data occasionally, having low energy

consumption.

Advantages and key selling points are

BATTERY LIFE, DEVICE COST and DEEP INDOOR

PENETRATION

As cellular networks already offer very good area cover-

age in cities, the advantage of NB-IoT appears on field and

indoor, where - due to the weaker signal-, traditional mod-

ules consume more energy. The deep indoor penetration

is achieved by a higher power density, as radio transmis-

sions are concentrated into a narrower carrier bandwidth,

and also repetitions are possible in case of poor coverage

at the expense of lower data rate. The small packages

transferred in long intervals require minimal energy, thus

offering the key feature of NB-IoT, the extreme long battery

life. The broadband (GSM/3G/4G) modules utilize servic-

es like mobile voice, messaging and high-speed data trans-

mission, which are not required when only low-speed but

reliable data transfer is the requirement. Leaving out these

functions make the modules cheaper and energy efficient.

In summary, there are strong market trends pointing at

growing demand for NB-IoT applications, Endrich, togeth-

er with its cellular module manufacturer Fibocom would

like to be pioneers of this technology. To introduce how the

infrastructure can be set up, the Endrich booth on Elec-

tronica 2018 will offer a working NB-IoT application:

Panasonic`s state-of-the-art GridEye thermopile array

sensor detects humans approaching the booth, and its 64

pixels thermal image will be transferred by Fibocom`s

M910-GL LTE CAT-NB1 module via T-SYSTEMS` NB-

IoT network to different cloud services. One of the cloud

servers is run by T-SYSTEMS, where the average tem-

perature of the sensor pixels and the ambient tempera-

ture is stored. Endrich has also set up a cloud server,

where all pixel temperatures are sent to (via UDP port) and

stored in a database. The transferred thermal picture will

be displayed on visitors` Internet enabled cellular phones

and a huge kiosk display from one of Endrich`s panel PC

supplier, Faytech.
