Read the seven benefits of LoRaWAN technology application
Internet of Things connection environment In addition to smart home networking and office space scenarios, many IoT device connection communications will be conducted in a remote environment. In the new environment, due to M2M transmission coverage limitations, this will result in inaccessibility and the need for power connections. With this in mind, the widely adopted LPWA solutions – the open standards of LoRAWANTM and 3GPP (LTE Cat M1 and Cat NB1) will provide solution support specifically for the obstacles encountered in these IoT connectivity processes.
LoRaTM and LoRaWANTM Interpretation
LoRaWANTM is a popular and widely deployed LPWA communication standard that uses an unlicensed radio spectrum in the ISM (Industrial, Scientific, Medical) band at frequencies of approximately 900 MHz or 430 Mhz (accurate frequencies vary from place to place around the world). Using unlicensed spectrum means that companies can easily roll out networks and provide private networks for businesses. LoRaWAN defines the communication protocol and system architecture of the network, while LoRaTM describes the radio layer. Using Rarp Spread Spectrum (CSS) modulation, LoRa is both energy efficient and offers a longer range than traditional alternatives. Due to its range and robustness of interference, CSS has been used in military and space communications for decades, but LoRa is the first low-cost implementation for commercial use.
The LoRa network has a star layout in which hundreds or thousands of devices communicate in both directions with the gateway connected to the core network and eventually the Internet. Signals from a single sensor or device are received by all gateways in range, which increases reliability and opens up the possibility of location services. The network uses a sophisticated "adaptive data rate" algorithm to fine tune the communication between each device and the gateway to minimize power consumption and maximize reliability.
What are the benefits of choosing LoRaWAN?
Coverage With CSS and ADR, devices can communicate with gateways up to 15 km in the open area, and can communicate with gateways up to 5 km in the city, which means that a single gateway can cover all around 700 square kilometers. device. Coverage also extends into the interior, reaching the basement or service pipeline below the street.
1, low power consumption and service life
Low power consumption and low peak current requirements, LoRaWAN data transmission and reception requires low current (less than 50 mA), which greatly reduces the power consumption of the device. One charge can make the device last for ten years, greatly reducing the support and Maintenance costs.
2, cost savings
Wide coverage and relatively low gateway costs significantly reduce the cost of LoRaWAN network deployment. For devices, the price of the communication module is in the $10 range, and the unlicensed spectrum means that the cost of the connection is only $1/year.
3. Location service
Since signals from a particular device can be received by multiple gateways, the location of the device can be calculated based on the signal strength and/or signal arrival time of each base station, enabling network-based location-based services that can be used to track or Geofence.
4, deep penetration
LoRa radio modulation allows for deep indoor penetration and increases the ability to reach sensors located in underground water meters or gas meters.
5, no need to obtain any frequency license
The LoRaWAN network is deployed in the free ISM band (EU 868, AS 923, US 915 Mhz), allowing any service provider or company to deploy and operate the LoRaWAN network without having to obtain a license for any frequency.
6, rapid construction and commercial
The combination of LoRaWAN open standards and low-cost operating frequencies and low-cost base stations enables operators to roll out networks with minimal investment in just a few months. Two-way communication Full two-way communication supports a variety of use cases that require uplink and downlink: for example, street lighting, intelligent irrigation, energy optimization, or home automation.
7, one-stop management
The LoRaWAN network supports multiple vertical solutions that allow service providers to manage a variety of use cases, such as smart buildings, precision agriculture, smart metering or smart cities, using a single platform and standards.
The difference between LoRaWAN and 3GPP technology
For many requirements, LPWAN requires the lowest cost and lowest power. In actual use cases (approximately 20 messages/day), LoRAWAN consumes five times better power than the LTE Cat NB1. The required peak current is reduced by a factor of 10 - equivalent to an order of magnitude reduction in battery size and a ten-year life extension.
Another major difference between LoRaWAN and 3GPP is the use of unlicensed spectrum. LoRaWAN allows easy deployment of "campus" networks with thousands of devices (smart cities, smart buildings, smart airports, smart factories) in a small area. The enterprise network can be completely under the control of the customer, and the data is still encrypted end-to-end.
