What benefits can LoRaWAN bring to you
description
Internet of Things connection environment In addition to smart home networking and office space scenarios, many Internet of Things devices will be connected and communicated in a remote environment. In the new environment, due to the limitation of M2M transmission coverage, this will result in inaccessibility and need for power connection. In view of this, the widespread use of LPWA solutions-the open standards of LoRAWAN and 3GPP (LTE Cat M1 and Cat NB1) will specifically provide the best solution support for these obstacles encountered in the Internet of Things connection process.

Interpretation of LoRa and LoRaWAN

LoRaWAN is a popular and widely deployed LPWA communication standard that uses unlicensed radio spectrum in the ISM (industrial, scientific, medical) frequency band with a frequency of about 900MHz or 430Mhz (the precise frequency varies around the world). The use of unlicensed spectrum means that companies can easily roll out networks and provide private networks for enterprises. LoRaWAN defines the communication protocol and system architecture of the network, while LoRa describes the radio layer. LoRa uses Chirp Spread Spectrum (CSS) modulation, which saves energy and provides 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 that can be used for commercial purposes.

The LoRa network has a star-shaped layout, in which hundreds or thousands of devices communicate with gateways connected to the core network and ultimately the Internet. The signal from a single sensor or device is received by all gateways in range, which improves 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, the device can communicate with gateways up to 15 kilometers away in open areas, and can communicate with gateways up to 5 kilometers in cities, which means that a single gateway can cover all around 700 square kilometers. equipment. The coverage also extends indoors, reaching the basement or service pipes below the street.

1. Low power consumption and service life

Low power consumption and low peak current requirements, LoRaWAN data transmission and reception require low current (less than 50 mA), which greatly reduces the power consumption of the device. A single charge can make the device life of up to ten years, greatly reducing the support and Maintenance costs.

2. Cost saving

The wide coverage and relatively low gateway cost significantly reduce the cost of LoRaWAN network deployment. For equipment, the price of the communication module is in the range of $10, and the unlicensed spectrum means that the cost of the connection is only $1/year.

3. Location service

Since the signal from a specific device can be received by multiple gateways, the location of the device can be calculated according to the signal strength and/or signal arrival time of each base station, thereby realizing network-location-based services, which can be used to track or perform device tracking Geofence.

4. Deep penetration

LoRa radio modulation allows deep indoor penetration and increases the ability to reach the sensors of water or gas meters located underground.

5. No need to obtain any frequency license

The LoRaWAN network is deployed on the free ISM frequency band (EU 868, AS 923, US 915 Mhz), allowing any service provider or company to deploy and operate the LoRaWAN network without obtaining any frequency license.

6. Quickly build and commercialize

The combination of the open LoRaWAN standard with no-cost operating frequencies and low-cost base stations enables operators to roll out the network with minimal investment in just a few months. Two-way communication Full two-way communication supports various use cases that require uplink and downlink: for example, street lighting, smart irrigation, energy optimization or home automation.

7. One-stop management

The LoRaWAN network supports multiple vertical solutions, allowing service providers to use one platform and standard to manage various use cases, such as smart buildings, precision agriculture, smart metering or smart cities.

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), the power consumption of LoRAWAN is 5 times better than that of LTE Cat NB1. The required peak current is reduced by a factor of 10-equivalent to a reduction in battery size by an order of magnitude, and the service life is extended by ten years.

Another major difference between LoRaWAN and 3GPP is the use of unlicensed spectrum. LoRaWAN allows easy deployment of "campus" networks (smart cities, smart buildings, smart airports, smart factories) with thousands of devices 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.
