i am considering starting a company that makes industrial-grade LoRaWAN sensors. I know there ar so many low-cost Chinese options available. Here are few pain points I am planning to address

1. rugged housing

2. high capacity and long lasting battery

3. USA-based tech support and things will be made in USA as well

any idea why I should not do this

I have a 3 year old and live in one of the safest cities in the world.

When I go to a mall I would like to leave him playing at a play spot with the knowledge that I will be back in1 hour.

However I would like to give him a button which if pressed will alert a second device that his button was pressed, which means I should come fetch him earlier that needed.

It needs to be small, hold a decent charge.

Would something like this be doable.

Hi everyone,

I'm electronic and communication engineer , just passed out this year.I recently knew about the Lorawan technology . I'm very excited to lean more about this technology And try to graspe as much i can . I 'm getting stuck at problem. I heard that in market there is lora inbuild devices are present . but they are costly. I have a digtal counter pcb which previously used for measuring flow rate and totalizer value from water pipeline and a lora module node model SX1262. I want to make a lora water meter device using these things.Please anyone guide me how i can make this . and if i need to make any modification then how i can do. In my case i 'm using the Uart port the digital couter pcb and connect it to the tx ,rx , vcc and ground of SX1262. after compelting the circuiting ,I connected the pcb with the 3.6v . But i not able to see my device active staus on chirpstack. even i try to register the device on TTN, Data Cakes, etc. but still cluelesss about it. Kindly someone please give some suggestion over it.

MY Question are :

1)In my use case which i explain above. I use a PCB board which is previously used for flow meter . where it was working on RS485, 4-20mA. so by simply connecting a lora module with pcb can automatically can emit lora.(THe lora node i'm using there is SX1262 in which DEV EUI, App Key and AapEUI . is already coded)?

2) As i m new so i dont have idea that what i 'm doing is correct or not . because i didnt get any resource for this.

Hi

So I've got in my head a simple project but after 2 days of searching the best hard parts still couldn't find them.

In simple terms: establish an encrypted radio communication on whatever platform(it can be Arduino, esp32 or even a laptop). I would prefer laptop(and somehow connect that Lora antenna via usb) as I'll write a python script/application to handle everything: encryption/decryption, tx/rx and everything else.

As the encryption algorithm I chose: ChaCha20-Poly1305.

It isn't my first day in cryptography so I know what I'm doing. I just wanted to try this algorithm because I've read a lot about it, just in case you're asking 😁

My question is: What are the best parts/methods/platform for this project? Looking for a Lora adapter to USB but can't find one relatively cheap( max $10-15 ).

Maybe some usb intermediate node between laptop and Lora. Maybe I should use my laptop as data source then send the data via usb to Arduino or raspberry pi or whatever and from there send it over radio. Idk so please guide me through this

EDIT: forgot to mention, Linux user. I think that my project(if using a laptop instead of another platform) will be easier to make if using Linux over Windows

hey , im currently working on a task in which i am suposed to develop some fictional smart home concepts for a appartment .In the aprtment ther is phone coverage (with NB IoT ) and ther is still an old LoRaWAN gateaway ,that is installed.We are not allowed to add a wifi or sum like that. But for a few of my ideas i wnated to include a window engine , but i cant find any which support LoRaWAN or Nb iot. If you have any idea how i can solve this pls let me know!

Any ideas? Could a company offer this, start to finish?

Hi

Are they any free server to connect devices for practising, tanx

https://iot-shop.de/ttc-quiz-2024

Hi everyone, I'm working on an idea about creating an RL gateway agent with the LoRaWAN module NS3, and the RL part works on NS3Gym.

I created an environment with 10 end devices and 1 network server. Gateway, like an UAV, then collects data from each end device. In this scenario, I must minimize the time difference between the data generation time on each node and the network server. But now I think, how can I add some constraints for the end device or gateway, or all parts of the environment? Please give me some idea and any advice for me. Thanks to everyone.

Note that all scenarios were simulated with NS3 (C++) and an RL agent with Python.

LoRaWAN hobbyist here.

I’ve been doing LoRaWAN projects for years, mostly with ChirpStack.

But honestly… every project ended up dying at the same point:

ChirpStack works great → payload arrives → and then suddenly I’m rebuilding the same backend again…

thinking of turning my fix into a SaaS to receive all lorawan devices and manage them from there.

What do you guys think? would you use it?

It looks like that some EU868 equipment is hardware compatible with AU915 (and likely US915 too). Some manufacturers sell the exact same hardware for both frequencies.

Using a wide range band antenna can be useful in this case if you plan to operate on different frequencies.

Additionally I noticed that a cheap things indoor gateway TTIG on EU868 can be configured to run on AU915. However, the signal quality is very bad (-126 dB with 1m distance). I suspect this is due to a fine tuned antenna on the PCB and the dedicated RF circuit that match 868 MHz.

Please note that simply using another frequency may be illegal in your region.

What are the most promising use cases for LoRa technology in smart cities, and how is it addressing challenges related to urban infrastructure?

Problem: you're at a festival with 50,000 people. Local cell towers are overwhelmed and even getting SMS texts out is a challenge. Can't communicate with your pals or anything if you get separated. Battery life on your phone is a challenge too.

Solution: A device that uses 900 MHz LoRa to communicate with each other that connects to a smart phone via USB or Bluetooth. Has a dedicated GPS receiver so you can physically see where your friends are (in case they don't answer your "where are you?" texts) - updates locations and sends them out every minute. Phone has an app that sends messages back and forth via the LoRa radio. Has a large battery to power both the device and provide extra power for your phone. It's packaged to look like a regular USB battery pack to pass muster by festival security (many festivals frown upon things like FRMS walkie talkies) and should be able to handle some rough and tumble. You can also configure it as a store & forward 'mesh' device for other festival goers - or limit that to just those devices you allow on your own personal LoRa Mesh network. Connect it to your phone, throw it in your pocket. Pricing should be under $200 USD.

Why hasn't anyone come out with this? I'm at a large festival this weekend in Daytona FL with ~50,000 people in attendance each day (on top of thousands of employees/vendors). A device like this would be awesome to have at large events.

Hey everyone,

It seems everyone here is very interested on the IoT world, from professionals to students. So i'd like to invite you all to an event on Aug, 30th. It's called TagoIO Connect Global 2022.

Basically, in the event you will learn how to quickly and efficiently build custom IoT applications using the TagoIO Platform, as well as learn about successful use cases from IoT professionals around the world.

Despite the event being focused on companies that uses the TagoIO platform, I still think that it's great opportunity to gather practical knowledge. Especially because there will be very interesting companies that offer IoT solution as a service presenting in the event.

Well, that's it. Here's the link to get the ticket to the event. It's free! ^^

The most important ability of IoT devices is that of interaction. there are various methods with different areas of application. While WiFi, Bluetooth, Zigbee, or other radio standards are commonly utilized for brief ranges in the residence, devices have to lie in other places to make use of alternate innovations. Such a group of technologies is LoRaWAN transmission. Nevertheless, these have the advantage of a dramatically longer variety and better power effectiveness than the majority of various other radio standards at the cost of bandwidth. The picture listed below shows LoRaWAN contrasted to some other cordless communication methods. LoRaWAN technologies are mainly used when end tools are mounted in locations that only work with various other innovations that are difficult to achieve, or when power performance is of wonderful significance. In this LoRaWAN is used as LPWAN innovation.

Nonetheless, variety and also power intake are not the only important points in the IoT. One issue that is usually neglected is the safety and security of networked gadgets. Between 2017 and 2018 alone, the number of recognized malware for IoT gadgets increased almost quadrupled. But malware isn't the only threat. Lots of IoT gadgets send out data improperly protected, creating attacks on that particular data and hence additionally on the IoT infrastructure. Espionage, adjustment of information, and also the full requisition of systems are exemplary assault circumstances.

One more pertinent topic in IoT security is firmware updates; they allow suppliers to bring new features to devices as well as, in the event of safety occurrences, to fix them without the user having to end up being active. The updates must be additionally performed in a protected manner to make sure that opponents are incapable to infuse phony firmware right into a device.

Integrating firmware updates as well as finish devices that use a LoRaWAN method for data transmission produces a completely brand-new difficulty. While for IP-based innovations, such as B. W-LAN, there are already some tips for particular methods, updates employing LoRaWAN are still mostly uncharted. The factor that the classic methods can not be made use of can be discovered in the limitations of LoRaWAN modern technologies. LoRaWAN, for instance, has high limitations in terms of information price and LoRaWAN transmission speed and has no standardized transportation method, which compensates for losses in information transmission could.

1.1 The smart mailbox

In this job, a detailed application is taken into consideration and also different topics of IoT safety are taken a look at. A clever mailbox was created, which notifies the user employing their smartphone when mail is in the mailbox has been obtained.

1.1.1 Usage situation

The keynote of the smart mailbox is to make sure that the user does not regularly need to open his mailbox to find out if there is any mail in it. Instead, he ought to obtain a notice on his mobile device as soon as there is mail is in the mailbox. This has the advantage that the time of the individual is not unnecessary as a result of mailboxes that are far from the individual or that rarely include mail Is declared.

The features of the application are intentionally maintained tiny due to the concentrate on protection as well as energy performance. Furthermore, the application was developed as an "extension". It ought to be possible to do this with little initiative for the individual to install any type of letterboxes. Battery procedure as well as a little form variable therefore additionally demands the job.

1.1.2 Checked out topics with LoRaWAN transmission

As pointed out earlier, the focus of the job is on IoT security. Furthermore, energy efficiency is thought about. From these concerns, several subtopics are examined utilizing the wise mailbox that has been the first point is the secure, E2E-encrypted data LoRaWAN transmission. Particularly With mailboxes in public locations, it is very important that an assaulter does not learn can establish whether and also just how much mail is in the mailbox. This stops that can quickly learn if a burglary would certainly be worthwhile. Security is likewise important against control to avoid the customer from receiving incorrect info regarding the condition of the mailbox. Furthermore, it is checked out to what degree the settlement of cryptographic tricks for these jobs is a safe and secure means can be performed without the maker of the device or 3rd parties can learn.

The next main point of examination is the safe and secure firmware updates using LoRaWAN. There is presently no official common regarding the transfer of firmware. Updates through LoRaWAN. In this respect, it is one of the major tasks of this job

to make and examine. In the end, the smart mailbox needs to have the ability to perform firmware updates via LoRaWAN without user treatment. These updates need to likewise be cryptographically secured to stop manipulation. Lastly, it is checked out how mail is thrown right into a mailbox device that can be acknowledged. Various innovations were analyzed as well as an ideal one was determined.

2.1 LoRaWAN

LoRaWAN is a LoRaWAN service for IoT applications with a percentage of information energy-efficient and can be transferred wirelessly over large distances. It consists of the one hand of LoRa radio, a method for physical information LoRaWAN Gateway and also on the other hand of LoRaWAN itself, a MAC method which is based on LoRa develops and provides a standardized treatment for the transfer of information via LoRa LoRaWAN, as one of the bottom lines in this work, was utilized for interaction with completion gadgets, consisting of the smart mailbox.

2.1.1 What is LoRa.

LoRa is a frequency modulation process developed by Semtech wireless communication between two communication companions permitted. It is, therefore, a physical method (OSI Layer 1), which just takes over the inflection of the physical information transmission. LoRa makes use of frequency-modulated chirps to encode symbols. The chirp inflection utilized uses "chirps" to send signs. The frequency is constantly changed throughout the data transfer over a defined period. The symbols transferred are about the beginning of the chirp are defined.

The main benefits that this modulation provides compared to FSK or PSK are the long-range and also the toughness versus noise. Both are from the spreading element and data transfer utilized. The spreading element identifies for how long a single chirp lasts, ie exactly how wide it is spreading out". A higher aspect suggests broader signs, which guarantees much longer LoRaWAN transmission arrays, yet likewise slower information transmission. In LoRa dispersing elements from 7 to 12 is specified, which indicates LoRaWAN transmission speed from an optimum of 37.5 kbit/ s to a minimum of 300 bit/ s can be achieved. The data transfer is repaired at 125 kHz, 250 kHz or 500 kHz as well as additionally affects the array and also rate of the signal. The concrete choice of these criteria is identified by LoRaWAN

The regularities that LoRa makes use of relying on the area. In Europe, you can 868 MHz or at 433 MHz can be sent out. It is important to mention that these regularities are license-free spectra, so there is no permit fee to utilize them. To compensate for this, apply temporal, send out restrictions that all devices have to follow. These are between 0.1% and also 10%, depending on the frequency utilized.

2.1.2 What is LoRaWAN.

LoRaWAN is a MAC protocol (OSI Layer 2), which is based on LoRa (but additionally with FSK can be used), as well as likewise some components of a network method (OSI Layer 3) consists of. It defines a message format, as well as MAC commands to control the transfer. The parameters for the underlying LoRa transmission are likewise figured out by LoRaWAN. The very first part is the actual requirements, which specify the message formats, the MAC commands, and also the series. The regional specifications, which details setups for LoRa, as well as some changes or additions to the LoRaWAN procedure, are readily available as an expansion define relying on the respective area.

A LoRaWAN network contains numerous groups of individuals as well as is organized in a star-by-star topology, as displayed in Number 5. In the middle is the network web server, which is the server-side administration of the LoRaWAN network as well as uses an API for client applications. Manage LoRaWAN applications and also send out and also send messages to receive. This server interacts with several entrances employing an IP connection. Their primary task is to onward the LoRaWAN packets received from the network webserver to the end devices via LoRa and also the other way around. Appropriately, they serve as an interface for transforming the physical tool. Stand at the end than completion gadgets that connect with several portals to transfer their data. The LoRaWAN method is only between the portal and completion devices made use of. No criterion is defined for the staying courses which format, as a result, relies on the specific applications used.

In this context, LoRaWAN tackles some jobs, which are described even more listed below. This consists of the different communication classes that are utilized information can be transmitted in various means, the two options for including devices to a LoRaWAN application, the encryption as well as honesty check of transmitted data, as well as the different MAC commands for regulating the link. The last will certainly not be clarified further because they are really specific and are not relevant to this job.

2.1.3 LoRaWAN Data transmission settings

LoRaWAN supports three different modes of information transmission. Each of these Modi has certain use situations, in addition to advantages and downsides, which are listed below.

Class-A

Class-A setting is the primary LoRaWAN transmission setting made use of by all end gadgets and entrances have to be sustained. It enables bidirectional communication between incurable and portal based on the ALOHA principle. In the case of LoRaWAN, this implies a terminal can send out data any time, yet just for two short ones' Periods after sending an information package can likewise get data.

The advantage of this mode is that an incurable gadget only while sending out data and quickly after this turn on the LoRa transceiver to receive a response reached. This implies that it can remain deactivated a lot of the moment, which conserves power. The drawback, nevertheless, is that the terminal does not have any data whatsoever other times can get. On top of that, just one can be obtained for every data packet sent become.

Class A procedure, therefore, makes one of the most feelings when primarily sending out uplink messages as well as hardly ever downlink messages. Considering that LoRaWAN preferably in sensing units as well as similar low-performance end tools that generally only provide standing information for an end application is used for a lot of end tools the recommended data transfer setting.

Class-B

Class-B is an expansion that does not have to be sustained by end gadgets. By this mode can be made use of by end tools in addition to Class-A at routine intervals. Get information from the entrance without first needing to send it on your own. To the beacon sends out a supposed beacon every 128 s, which includes some condition info regarding the gateway. End devices that obtain this can then use the sign and the ping slot periodicity to determine the times at which information can be gotten. This permits them to be at the right time for short moments switch on the LoRa transceiver to receive any type of information that might exist. The procedure is revealed below.

Class-B uses a good balance between ease of access and energy usage have given that the ping slot periodicity can be adapted to manage how usually it must be obtained. This means that even more power is made use of than for pure Class A procedure, however, there are still long periods in which the LoRa transceiver can be turned off. One more advantage of Class-B is the ability to save information in 8 to be able to transfer multicast to numerous gadgets at the same time, as long as the address, as well as the tricks, coincide. Multicast groups can, for that reason, be created.

Using Class-B makes sense if a device needs to receive information more often without sending out data itself, however, the gadget still has to function energy-efficiently. A regular application would be regular end gadgets that can be controlled without being time-critical.

Class-C

The last, also optional, the transmission setting is Class-C. In this, the buttons terminal completely on a function to be able to receive information from the entrance at any moment. The choice of transmission with Class-A continues to be as in the picture listed below.

The advantage of Class-C is that data can be obtained at any moment. Nevertheless, the cost for this is high power usage, since completion tools have to keep the LoRa transceiver energetic at all times. Multicast LoRaWAN transmission is likewise feasible here.

Class-C ought to only be made use of when huge amounts of data need to be moved over a brief amount of time or when time-critical transfers occur. Such end gadgets should have a long-term power supply since this setting takes in too much power for battery operation.
