LoRa and SigFox – Low Power Networking for Smart Buildings
LoRa and SigFox - Low Power Networking for Smart Buildings
LoRa and SigFox are low power, wide area networks (LPWAN) that share data and communications wirelessly. Both protocols utilise radio signals to enable long-range communication, whilst consuming very low levels of power. This provides an efficient method to wirelessly connect and transmit data to the internet whilst decreasing the reliance on strong WIFI signals – ideal for the Internet of Things (IoT). Some uses of these protocols within the IoT include smart devices as well as equipment that measures and records data in real-time.
LoRa and Sigfox are similar in that they both facilitate the ability to communicate across large areas whilst using low amounts of energy. However, a large difference between the two protocols is that LoRa provides for bi-directional communication, whilst Sigfox is optimised for one-way communication. The two-way communication utilised by LoRa allows for wireless integrations with possible options including the ability for users to send prompts to devices connected to LoRaWAN gateways.
The Benefits of Low Power Wide Area Networks
Lora and SigFox provide a range of features that allow for efficient communication. One of the main advantages of these features is the relatively low cost of sending large masses of data compared to traditional methods such as via WIFI or cellular connections. This is furthered by the ultra-low energy consumption of the protocols and allows connected devices to last up to 10 years on battery power, offering the ability for users to connect and forget.
The long-range capabilities of the technologies allow connected devices to transmit data over large distances with LoRa's range reaching up to 15 kms. This is helpful for areas that have traditionally suffered from poor WIFI and cellular availability whilst enhancing the communication capabilities. The reach of the networking protocols allows users to set up successful networks in rural, regional, and city areas.
In terms of security, both LoRa and SigFox utilise end-to-end encryption. This provides a high level of security that helps to protect transmitted data. The security is furthered with both protocols using Virtual Private Networks (VPNs) and mutual authentication to help ensure only authorised users can access the networks.
The Impacts of LPWAN Protocols on Sensor Monitoring Technology
Both protocols are ideal for their applications in data measuring and monitoring equipment. This is due to the low cost and energy output of devices connected to the networks, whilst being able to consistently transmit data and therefore improving reliability. The low cost and wide range of the protocols is optimal for the Internet of Things and helps the networks to handle the large load of associated data more efficiently than WIFI networks.
One of the factors of LPWAN protocols that make it attractive for sensor monitoring technology is the ability to transmit data from a large number of devices. This would not be feasible on traditional networks due to cost and the size of the data. The ability for these data points to be transmitted is optimal for applications that require many sensors, such as measuring and recording data in a number of individual rooms throughout a building.
Utilising LPWAN protocols in Sensor Monitoring Technology
One such successful utilisation of an LPWAN protocol is Air-Met’s range of Carbon Dioxide (CO2) monitors which feature LoRa connectivity. The range of CO2 monitors and detectors are used to provide real-time visibility into the quality of indoor air by monitoring CO2 levels. High levels of CO2 in a room indicates poor indoor air quality and can present a range of health issues to occupants. Some of which include issues with respiration, headaches and decreases in mental capacity. CO2 can be monitored using detectors such as the ERS CO2 Carbon Dioxide Sensor. Due to the reliability of the LoraWAN protocol, recent applications of the LoraWAN technology has seen schools, universities and office buildings monitor for indoor air quality using CO2 sensors. This has led to the improvement of ventilation to prevent the transmission of airborne viruses.
