LoRaWAN GPS tracker knowledge that you need to know?

LoRaWAN technology uses low power to transmit data over medium and long distances at low bit rates, so the data being transmitted is limited. Unlike other GPS devices, LoRa can transmit GPS location data over long distances, but at slower speeds. And LoRaWAN’s network is secure and privatized, so it fits a lot of IoT scenarios.

Why LoRaWAN used in IoT application?


The internet of things will also extend to remote environments, because of the limited M2M transmission coverage in the new environment, it is inaccessible and will require a power connction. The open LPWA standards of LoraWAN and 3GPP (LTE Cat M1 and Cat NB1) provide a solution that supports these barriers to IoT connectivity. That’s why iSmarch has the advantage of producing a Lora Iot Watch?

Lora and Lorawan

Lorawan is a widely used LPWA communication standard that operates by using unlicensed radio waves in the ISM (industrial, scientific, medical) band at frequencies ranging from 900 mhz to 430 mhz (the exact frequencies vary from place to place). As a result of using unlicensed spectrum, companies are able to create their own private networks easily. Lorawan defines the networking protocol and the system architecture, and Lora describes the radio layer of the network. Lora is powered by Chirp Spread Spectrum (CSS), which is energy-efficient and more powerful than traditional technologies. CSS has been used in military and space communications for decades due to its range and robustness, but Lora is the first commercial low-cost implementation of CSS.

Lora Network:

Lora Network has a star-shaped layout where hundreds or thousands of devices communicate both in and out with gateways to the core network, which ultimately goes to the Internet. Signals from a single sensor or device are received by all gateways within a range, which improves reliability and opens up possibilities for location services. The network uses a complex “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 up to 15 km of gateways in open areas and up to 5 km of gateways in cities, this means that a single gateway can cover 700 square kilometers of all the surrounding equipment. Coverage also extends indoors to the basement or below street service pipes.

1.Low power consumption and lifetime

Low power consumption and low peak current requirements for Lorawan data transmission and reception require low current (less than 50ma) , greatly reducing the power consumption of the device, which can last up to 10 years on a single charge, greatly reduced support and maintenance costs.

2.Save costs

Extensive coverage and relatively low gateway costs significantly reduce the cost of LoRaWAN network deployment. For devices, the price of a communications module is in the $10 range, and unlicensed spectrum means the cost of a connection is just $1 a year.

3.Location Based Services

Since signals from a specific 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, thus enabling network-based location services, can be used to track or geo-fence equipment.

4.Deep penetration

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

5.No frequency permission required

The LORAWAN network is deployed on the free ISM band (EU 868, AS 923, US 915 Mhz) and allows any service provider or company to deploy and operate the Lorawan network without having to obtain a licence for any frequency.

6.Quick build and commercial

The Lorawan Open Standards, combined with cost-free operating frequencies and low-cost base stations, enable 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 both uplink and downlink: for example, street lighting, intelligent irrigation, energy optimization or Home automation.

7.One Stop Shop

The Lorawan Network supports a variety of vertical solutions that allow service providers to use a platform and standards to manage use cases such as smart buildings, precision agriculture, smart metrics, or smart cities.

The difference between Lorawan and 3GPP technology

For many requirements, LPWAN requires the lowest cost and the lowest power. In practice (about 20 messages per day) , Lorawan consumes five times more power than LTE CAT NB1. The peak current required has been reduced by 10 times — the equivalent of a reduction in the size of the battery by an order of magnitude — and its life has been extended by 10 years.

Another major difference between Lorawan and 3GPP is the use of unlicensed spectrum. Lorawan allows the 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
