In this article, we'll look into different IoT wireless technologies. We'll analyze :● 3G, which use cellular line to send data● SigFox, with its growing coverage● Wireless M-Bus if you need your own network infrastructure or hidden

area with no other coverage (for example tunnels)

● Standard: GSM/GPRS/EDGE(2G), UMTS/HSPA(3G), LTE(4G)● Frequencies: 900/1800/1900/2100MHz● Range:35Km max for GSM, 200Km max for HSPA (Depending on ISP)● Data Rates (typical download): 35-170kbps(GPRS), 120-384kbps(EDGE),

384-2Mbps(UMTS), 600kbps-10Mbps(HSPA), 3-10Mbps(LTE)● Power Consumption: 580mA during transmission (depends on signal

quality)

• GMS/2G/3G can be the right choice for IoT application that requires long distance transmission.

• Cellular line has a great bandwitdh, but subscription cost and power requirements are not that low.

• The industrial applications of smart devices usually ask for low bandwidth, except those who make video or audio streaming.

● Frequencies: 868MHz ISM Frequency● Range: Long Range, 30-50Km(rural environments), 3-10Km (urban/noisy

environments)● Data Rates: 10-1000bps● Ultra Narrow Band: few seconds transmission for a maximum of 140 times

per day (12 bytes payload)

● Low Band Pass: 100bit/sec (perfect for IoT short messages)● SigFox receiver: UNB Technology with Cognitive SDR -140dBm (5-20Km

range) and handles 3000000 devices.● Power Consumption: 61mA during transmission

• SigFox is going to fill the spot between wi-fi and cellular line. Some application require indeed only few data transfers (like miniOMNIAlogdatalogger) and requires to run on battery for long periods of time. The ISM band is license-free.

• The idea for SigFox is that many m2m application runs on small batteryand only need few data to be transfered.

• SigFox is expanding fast, with 24 countries reached:• France, Spain, Portugal, Netherlands, Luxembourg, Ireland, U.S., U.K.,

Belgium, Denmark, Italy, Czech Republic, Mauritius Island, Germany, Australia, New Zealand, Sultanate of Oman, Brazil, Finland, Malta, Mexico, Singapore, Taiwan, Colombia.

4WIRELESS W-BUS

15

• The 169 Mhz Wireless M-Bus is the wireless variant of M-Bus standard. Born for remote reading of gas and electricity meters, soon become an european standard (EN13757).

• It was developed to provide a system for remote reading of utility meters, like consumption of electricy in the home.

4WIRELESS W-BUS

16

● Frequencies: 169/868MHz● One/Two Way Narrowband VHF● NRZ-encoded● Optimized for narrowband and long range (5Km in line-of-sight)● Star Architecture● Power Consumption: 730mA during transmission

4WIRELESS W-BUS

17

• M-Bus (and its wireless variant) grant power requirements of battery-powered devices.

• M-Bus is also commonly used in alarm systems, smart illuminationsystems and other application which require low power consumption and sturdy communication protocol.

SigFox 2G/3G Wireless M-Bus

Connection charge Yes Yes NoInstallation cost SigFox provides the

radio infrastructure, no need to create one.

Using cellular line avoid the cost of your own radio infrastructure.

You need to create your ownradio network, with at least a gateway in reachof the transmitters.
