LoraWAN Advantages for IOT

LoraWAN advantages for the Internet of Things, or IOT, are discussed in this article.

LoraWAN is a low data rate, low power, long distance wireless technology.

The ‘Lora’ part of the name, stands for ‘LOng RAnge’.

LoraWAN is designed for Internet of Things (IoT) uses.

LoRa technology offers bi-directional communication, end-to-end security, mobility and localisation options.

LoRa typically operates within license-free ISM (Industrial, Scientific, Medical) radio frequency bands located below 1 Gigahertz (GHz).

Operating in the ISM frequency bands, allows anyone to build a LoraWAN network, without the cost of Ofcom (in the UK) spectrum operating licences.

Lora technology provides very long-transmission range, compared with Wifi & Bluetooth etc, while using exceptionally low power consumption.

There are of course IOT applications that are better suited to other wireless technologies, such as Wifi.

LoraWAN can only transmit small amounts of data at a time, so is not suitable for streaming video for example.

Lorawan Advantages are listed below:-

Long range and deep penetration

LoraWAN is good at penetrating into buildings, or even underground. Therefore Sensors can be located indoors, outdoors and even underground, and still be able to communicate with the receiving Gateway device.

Distances of up to 50Km can be achieved in open areas, and up to 10km within a town or city.

Low Power

LoraWAN advantages for IOT is offering low data bit rates, which results in low energy consumption.


Environmental Sensors such as Smart Parking or Soil sensors are designed with Lora technology, to send small amounts of data when required.

How often the small amounts of data are sent can be designed to be event-driven or at a scheduled time period.

This enables battery life to last for up to 10 years.

High Network Capacity

Lora uses an adaptive data rate and features a multi-channel multi-modem transceiver in the gateway device.

This allows for simultaneous messages to be received on on multiple channels.

Therefore a LoRaWAN network has very high capacity and scalability options..

Open Standard, unlicensed band

The LoRaWAN specification is supported and maintained by the LoRa Alliance.

LoraWAN mostly operates in the licence free ISM (Industrial Scientific Medical) bands.

In Europe the frequency is 868MHz, and 915 in the USA etc.

Advantages of LoraWAN operating in an ISM band, is that there are no expensive licence fees to be paid to local regulatory bodies (Ofcom in the UK, for example).

Potential disadvantages of using unlicenced frequency spectrum, is interference from other users.

Security

LoRa has AES-128 encryption built-in as standard.

Ease of Installation

As Lora connected Sensors consume only tiny amounts of power, they can run from batteries for a number of years. This makes installation simple, as time consuming & expensive cabling isn’t required.
