Comparison between LoRa and other wireless technologies

Apparently, the world is a global village, and people need to communicate, participate in projects and events virtually, and execute tasks remotely. Therefore, there’s a need for internet, multimedia, and most crucial, wireless communication networks. With wireless technologies, people can share data, voice, images, and even videos in a snap. Services like TV, Radio, cellular telephone, and live conferencing are made possible by wireless technologies. This shows how wireless communications systems have become an integral part of human’s day-to-day lives.

What is wireless technologies?

It’s a way of transferring information from point A to B (or between two or more points) without using any electrical conductor or physical medium. There are 3 main types:

  • The Wireless Wide Area Networks (WWAN).

They use radio waves, but the mother network uses wires but transmits to one or several wireless access points where a wireless user can connect to the wired network.

  • The Wireless Personal Area Network (WPAN)

They are short-range networks (usually a 30ft range) utilizing Bluetooth technology. They interconnect compatible devices like phones, pcs, Bluetooth beacons near a central location.

  • The Wireless Local Area Network (WLAN)

Comes as a result of mobile phone signals provided by cellular service providers.

What are the main elements of a wireless communication system?

A basic Wireless Communication System has 3 main elements:

  • The transmitter

It has an encoder that receives information from the source and converts it into a readable signal. The info is then encrypted by an Encryption standard then transferred to an Encoder. The Encoder minimizes faults in the information like noise to get a modulated signal. It’s then multiplexed and sent to the channel.

  • The Channel

It’s the medium of transmitting information signals from the sender (transmitter) to the recipient (receiver).

  • The Receiver

It’s work is to reproduce the source information signal after receiving it from channel. The receiver undoes what the transmitter did, and that’s why the receiver path has the demultiplexing, demodulation, channel decoding, decryption, and source decoding.

LoRaWAN vs. other IoT wireless technologies

LoRaWAN vs. other IoT wireless technologies

IoT devices are all the rage nowadays. In fact, every second, 127 previously ‘dumb’ devices are given access to the internet. From shoes and vehicles to homes and clothing, there is no end to the number of devices that are increasingly joining the IoT world. The market for smart devices is widening by the minute, with smart home devices having a 69% penetration in the US.

Better yet, IoT devices are making manufacturing processes easier, from quality control to production floor monitoring. Ideally, providing your client base with these IoT devices is bound to make their life easier, but you need to first understand how it all works. The first step is to understand the wireless technologies around IoT connectivity; LoRa, LoRaWAN, LTE.M, WIFI, Zigbee, Bluetooth, and 5G. Lucky for you, this section breaks down each wireless technologies compared with LoRaWAN to help you understand them better.

LoRaWAN vs. 5G wireless technologies

5G is superior to LoRaWAN, but the latter is meant to replace the former before 5G can become more widespread. Ideally, 5G has the ability to send more data faster and with little hassle. However, setting up the infrastructure required for 5G requires time and a lot of investment before it can become a viable option.

On the flip side, LoRaWAN has been the go-to network for IoT devices, especially in the industrial setup. These are devices that can reliably send very small data packets, from temperature to humidity.

LoRaWAN vs. Bluetooth wireless technologies

One key takeaway in the LoRa vs. Bluetooth debate is that both have been key drivers in the IoT world. In fact, each could easily be integrated together for better functionality. While Bluetooth tends to be less battery hungry than Wi-Fi and LTE, it is still more power-hungry than LoRa, except if you are using Bluetooth low-energy. It covers a shorter range than LoRa, making it ideal for devices in close proximity.

LoRaWAN vs. LoRa wireless technologies

It’s common for most people to use these terms interchangeably, though the two are quite different. It all trickles down to the layer of the telecom device that the network interacts with. Long Range, abbreviated as LoRa, is a radio wave carrier signal that interacts with the physical layer of the device. If you have a LoRa modem, you can turn your data into transferrable signals. While there are other networks like it (Wi-Fi and Bluetooth), LoRa is better in that it has a wide communication range and it improves receiver sensitivity.

LoRaWAN, on the other hand, is what connects/links the Long-Range signal to the application. It controls both the architecture and protocol by letting you track nodes’ battery life, the security of transmitted data, and even network capacity. It simply helps you to better use the IoT device while also facilitating the transfer of data to the cloud.

LoRaWAN vs. LTE-M wireless technologies

LTE-M, just like any other cellular network, is already well-established. The network has a strong data throughput, but it lags behind when it comes to battery life. LTE-M is also complex to launch, making it unsuitable for fast-deployment projects.

On the flip side, LoRaWAN is simple to deploy. What’s better is that the technology has better battery life and is designed to be native to IoT devices.

LoRaWAN vs. Sigfox wireless technologies

In most cases, people are interested in the Lora vs Sigfox comparisons, owing to how dominant both technologies are in the IoT world. While Sigfox covers a smaller area than LTE-M, it has been designed especially for low data transfer devices. Among its major benefits is that it provides an entirely different network for IoT devices.

LoRa strikes a balance between coverage area, the data rate as well as power usage due to its CSS (Chirp Spread Spectrum) modulation. It operates under an unlicensed radio spectrum while providing a completely separate network.

LoRaWAN vs. Wi-Fi wireless technologies

The best way to describe the LoRa vs. Wi-Fi discrepancies is to go back to the basics. Any network type can only have two of three characteristics; long-range, low power consumption, and high bandwidth. While Wi-Fi is superior when it comes to bandwidth, it suffers when it comes to battery life and range. Most networks might struggle to work past 15 meters, which makes it unsuitable for scattered IoT devices.

In comparison, the low power and long-range nature of LoRa make it ideal for these devices. However, LoRa will struggle to send a single image, let alone large files. It thrives at sending small packets of data, such as temperature and humidity.

LoRaWAN vs. Zigbee wireless technologies

The key selling point for LoRaWAN is that it is low cost, long-range, and low power sensing, which make it a great rival or Zigbee. Among the major variances in the LoRa vs. Zigbee debate is the fact that LoRa uses a star network topology while Zigbee uses a mesh network topology.

What this means for LoRa is that each device node communicates with a specific gateway. In the case of Zigbee, each node can communicate with any other node in the mesh network, making it ideal for distant multi-hopping. When used with the right device design, Zigbee can easily rival the power efficiency of LoRa.

LoRaWAN vs. Z-wave wireless technologies

Z-Wave and Zigbee are quite similar in that they are both low-power networks that work under a mesh protocol and are meant for short to medium-distance data exchange. On the flip side, LoRa runs under a star network topology, where every node communicates with a specific gateway.

LoRaWAN vs. NB-IoT: A comparison between IoT trailblazers

While both networks typically support geolocation at roughly the same degree, there are some differences between them. LoRaWAN consumes less power than NB-IoT, making it ideal for any project that requires fast refresh rates. The battery of its devices can last up to fifteen years, compared to the ten years of NB-IoT. However, the latter has a better data throughput than the former.

One thing that comes up in the LoRa vs. NB-IoT debate is the difference in data security. NB-IoT is also much more secure due to superior encryption and has a lower latency. The latency on LoRaWAN depends on the specifications of the device in use.
