Hardware solutions for Eclipse IOT Challenge: Exploring LoRa/LoRaWAN

The Eclipse IOT challenge lead me to research more in depth different technologies both from the hardware and the software aspect. As part of product development and delivery one has to come up with the solution for a problem. In this case the problem is parking in urban areas, or the lack of smarter parking solutions. Such implementation would not only allow end users to have a better parking experience while saving time in finding an adequate spots but also provides the city with valuable data to be used for city planning and city improvement projects.

Once the issue is identified, it was important to find a technical solution that would align with our needs. For city implementations, given the broad area that needs to be covered, we would need a type of communication that is long range and low cost, both in cost of sending data and power consumption. I first tackled the hardware needs once the design was evaluated. The prototype for a smart city solution needs to also be scalable while adding the least overhead in cost and infrastructure needed.

In this article I will go more in depth on the research done to identify one of the key components of the project. I will share a summary of my findings in hopes of helping others that are also exploring similar solutions.

Evaluating communication solutions:

I evaluated BLE, bluetooth, cellular, satellite, Wi-Fi, SigFox, Zigbee and Lora. Bluetooth and Wi-Fi, given its range limitation and cost were not considered for this prototype. Cellular communications have a higher cost as well, and at even steeper price comes satellite communication; both this options were also discarded. SigFox and LoRa/LoraWAN were the runner up candidates. I came across a comprehensive post on the comparison of SigFox and LoRa that is worth the read https://www.link-labs.com/blog/sigfox-vs-lora . The winner was LoRa.

Why Lora?

As explained by Libelium on http://www.libelium.com/development/waspmote/documentation/lora-vs-lorawan/ LoRa contains only the link layer protocol and is perfect to be used in P2P communications between nodes. LoRa modules are a little cheaper that the LoRaWAN ones.. LoRaWAN includes the network layer too so it is possible to send the information to any Base Station already connected to a Cloud platform. LoRaWAN modules may work in different frequencies by just connecting the right antenna to its socket..

LoRa which stands for long range wireless operates at a low bandwidth, meaning that its best application is for sending smaller pieces of data such as sensor data. LoRaWAN is known for its good penetration and long coverage which has been recorded to reach over 10 KM distance. LoRaWAN operates on unlicensed bands, so in most countries is legal to have you own LoRaWAN gateway cutting down the cost given that you will not have to pay a carrier or third party to supply you with the service.

Additionally a selling point for me personally was the wide accessibility to various developer platforms and hardware solutions such as DIY LoRa kits, libraries and Arduino compatible LoRa modules. The Things Network offers a strong platform with access to resources, documentation and a great community of IOT LoRa enthusiast.

Gateway

Lets take a look at one of the hardware pieces now. “Gateways form the bridge between devices and The Things Network. Devices use low power networks like LoRaWAN to connect to the Gateway, while the Gateway uses high bandwidth networks like WiFi, Ethernet or Cellular to connect to The Things Network. Gateways are routers equipped with a LoRa concentrator, allowing them to receive LoRa packets”(see more at https://www.thethingsnetwork.org/docs/gateways/). Below is a list of some gateways that were evaluated for this project. I spent time looking at their platform flexibility, the documentation and support provided and what would be the most cost effective solution for a minimum viable product (MVP).

Based iC880a concentrator board and a Raspberry Pi 2.

A DIY low-cost LoRa gateway

http://cpham.perso.univ-pau.fr/LORA/RPIgateway.html

The gateway is based on a Raspberry PI. RPI 1B+/2B/3B can be used. The LoRa modules comes from (a) Libelium LoRa radio module, (b) HopeRF RFM92W/HopeRF RFM95W (or RFM96W for 433MHz), © Modtronix inAir9/inAir9B (or inAir4 for 433MHz), (d) NiceRF LoRa1276. Libelium LoRa and RFM92W use the Semtech SX1272 chip while RFM95W, inAir9/9B and NiceRF LoRa1276 use the SX1276 which is actually more versatile.

Note: The LoRa module and the LoRaWAN module are not compatible because the protocols are different. The LoRa module implements a simple link protocol, created by Libelium. However, the LoRaWAN module runs the LoRaWAN protocol, a much richer and more advanced protocol, created by the LoRa Alliance.

Check out their Github page with detailed documentation https://github.com/CongducPham/LowCostLoRaGw

Conclusion on gateways:

The gateway is a key portion of this solution given that the sensors will need to send the information “somewhere” where it can either be analyzed on the edge or sent to the cloud. After considering price ranges on both the parts needed for a DIY solution or a full blown gateway I considered those solutions that would be cost effective and which I was most familiar with. The “LG01 LoRa OpenWrt IoT Gateway by Dragino Tech” seemed the best approach. The developer kit counts with an Arduino developer node and a Developer gateway. Note that this solution only counts with ONE channel, in comparison with other solutions that allow 8+ channels. This was a compromise that was evaluated and given that this will be a prototype the one channel option seemed sufficient.

In the following articles I will showcase both the remaining hardware parts and the software portion along with updates on how the project is coming along.

New Post has been published on http://engineer.city/shock-and-vibration-resistant-rf-connector-for-the-automotive-industry/

Shock and vibration resistant RF connector for the automotive industry

The engineers at I-PEX Connectors have designed automotive applications to handle the unique problems that stationary RF systems do not encounter, particularly shock and vibration.

Cars are in motion, roads are uneven, and this generates mechanical harmonics that could cause connectors to disengage over time.

Designers concerned about RF connectors that disengage from the PCB on high shock and vibration applications can rely on a new connector with a built-in locking feature.

The new MHF brand I LK Micro RF Coaxial Connector and Wire Harness from I-PEX is designed with a built-in lock that keeps the connector in place on the PCB.

Designers no longer have to adhere their RF connectors with messy epoxy or adhesive. This new locking mechanism keeps the connector in place on the board, increasing productivity and reliability.

This connector has the same features as the tiny MHF I Connector, which is used to connect antennas to radios and for testing radios while maximising performance within minimal space.

Because of the tiny size of the connector, engineers have greater flexibility in designing their PCBs. This connector supports many of the new transmission standards, including Wi-Fi, 4G LTE, Bluetooth, GPS, M2M, IoT. SigFox, WiSUN, NB-IoT and LoRa.

They are suitable for high shock and vibration applications, particularly in the automotive, airline and drone industries.

The MHF I LK Connectors are available in a variety of cable sizes and lengths: O.D. 0.81 mm, 1.13 mm, 1.32 mm, 1.37 mm and 1.80 mm.

Keeping the connectors in place gives designers the freedom to focus on their own innovative solutions, especially as today’s drivers are demanding Smart Car connectivity like never before.

This demand has industry leaders investing heavily in Internet of Things (IoT) technologies to advance Smart Car connectivity at an astounding rate.

In fact, Business Insider estimates the automotive industry will ship 94 million connected cars in 2021. This figure, which represents 82% of the industry, says a lot about the demand by today’s drivers for this rapidly evolving technology.

Currently, Smart Car connectivity occurs in two ways. Embedded cars utilise a built-in radio and antenna connecting to local cellular networks, while tethered cars use a wireless connected device, typically a cell phone, to provide the data connectivity.

This is done via Bluetooth or a USB cable. In addition to data connectivity, cars have GPS for navigation and emergency services, satellite radio (Sirius), hands-free calling, sensor and data gathering, as well as key-less entry and start.

Some of these system like tire-pressure monitoring, can utilize an embedded or board-level antenna.

Others, like emergency services or data-intensive systems like navigation or satellite radio require an external, application-specific antenna.

Despite these highly varied requirements, I-PEX Connectors is able to offer a robust and diverse product offering to suit critical RF interconnectivity needs for all of these systems thanks to I-PEX’s patented iFit MHF Micro RF Coaxial Connector Series.
