Is LoRa faster than WiFi?
Put simply, LoRaWAN boasts tremendous abilities when you need long range, but it can't compare with Wi-Fi when it comes to data rates. One potential competitor may eventually be cellular data, which boasts both excellent range and good data speeds.
What protocol does Sigfox use?
Sigfox uses Ultra Narrow Band (UNB) technology combined with DBPSK and GFSK modulation. Each message is 100 Hz wide and transferred at 100 or 600 bits per second data rate, depending on the region.
Is Sigfox a LoRa?
sigfox is a similar radio protocol, but closer to the cellular network in style. Rather than set up your own LoRa network, sigfox is an existing network set up by the self-same company. You can only use sigfox chips in a location where there is an existing network set up, but many cities have one.

What protocol does Sigfox use?
Sigfox uses Ultra Narrow Band (UNB) technology combined with DBPSK and GFSK modulation. Each message is 100 Hz wide and transferred at 100 or 600 bits per second data rate, depending on the region.
What is the Sigfox technology?
Sigfox technology is a narrowband (or ultra-narrowband) technology. It uses a standard radio transmission method called binary phase-shift keying (BPSK), and it takes very narrow chunks of spectrum and changes the phase of the carrier radio wave to encode the data.
What is collaborative reception?
The principle of collaborative reception is that no end device is attached to a specific base station, unlike traditional cellular networks. Messages sent by a device can be received by any nearby base station, and the average number of receiving base stations in a real deployment is three.
What is random access?
The transmission between the network and the device is asynchronous. The device sends a message at a randomly selected freque ncy, and then sends two other copies at different fre quencies. This use of frequency and time is called time and frequency diversity.
How does Sigfox downlink work?
Downlink messages are triggered by the end device, and the Sigfox cloud server receives the message with the downlink trigger identifier from the device and negotiates with the client-server to send the downlink message. After the device sends the first frame of the triggered downlink message for the 20s, there will be a reception window with a maximum duration of 25s. The downlink frequency is the frequency of the first frame of the uplink message plus a known offset.
What is the bandwidth of Sigfox?
Sigfox technology uses a common frequency band of 192 kHz spectrum bandwidth to transmit signals, using ultra-narrow band modulation, with a transmission width of 100 Hz per message and at a data rate of 100 or 600 bits per second, depending on the network configuration of the area.
Can you use Sigfox with Wi-Fi?
Thanks to its low cost and ease of sendable use, customers can also use Sigfox as a complementary solution to any other type of network, e.g. Wi-Fi, Bluetooth, GPRS, etc.
What band is Sigfox?
Sigfox utilizes 192KHz Ultra Barrow Band (UNB) integrated with the base station’s spatial diversity of +20 dB which facilitate its unique anti-jamming features. The Sigfox network utilizes Ultra Narrow Band to operate in Industrial, Scientific and Medical (ISM) band since spread spectrum signals are interfered by UNB signals. In Europe, the Uplink has a bandwidth of 100Hz while in the USA the bandwidth exceeds to 600Hz. The European Union has limited the maximum power to be 25mW. The downlink has a channel bandwidth of 1.5KHz and a data range of 600 bps. The downlink further limits the maximum power output to 500mW. The optimal resilience to interfere facilitate Sigfox to function effectively in the ISM band. This allows it to transmit even under jamming signals. However, the low noise overlap induces intrinsic ruggedness to the Ultra-Narrow band. As a result, for a message to be transmitted, the signal should have at least 8 dB.
What is Sigfox wireless?

What is Sigfox security?
The Sigfox architecture provides a security mechanism that guarantees secure data authentication and replay avoidance ; it also provides an extra anti-eavesdropping mechanism. The Sigfox’s IoT chain involves authentication keys stored which are stored by devices and the customer, this key will be required to access the data stored by the Sigfox System. As a result, Sigfox’s data mechanisms guarantees security within the diverse ecosystem and different local regulations. The authentication key for every device is unique meaning that a compromise of a device’s authentication security key does not affect the security of other devices. However, the security of any device is left at the discretion of the manufacturer.

Why did Frese choose Sigfox?
Sigfox was chosen because they have a unified platform that can be used worldwide. It’s a super-easy, consistent technology that fits perfectly in Frese’s setup, where battery life is important and the amount of data is very small. Frese FLOWGUARD and Frese BYPASS do not need to exchange more data, the rest is built into the controller firmware. So, it just needs to know what to do, and then it will figure out the rest for itself.
