Manufacturers of LoRa IOT Barrel Antenna in India 2023

A barrel antenna, also known as a "can" or "cylinder" antenna, is a type of antenna that has a cylindrical shape resembling a barrel. This design offers specific benefits for certain applications, particularly in terms of directionality and gain.

The barrel antenna design can provide some directivity and gain due to its shape. It can be particularly useful when you want to focus the radio frequency (RF) energy in a specific direction, or when you want to achieve a higher signal strength in a particular area. However, it's important to note that the gain and performance of an antenna depend on various factors including the frequency it's designed for, the materials used, and the surrounding environment.

Transferência de Arquivos via LoRa

Um projeto que venho fazendo há alguns meses e que muitas pessoas estavam interessadas em transmitir imagens e agora será possível, mas claro, respeitando as limitações.

Transferência da arquivos via LoRa é possível assim como qualquer outra modulação, mas existem desafios particulares nessa tarefa que em outras modulações podem ser mais f��ceis.  Sobre a modulação LoRa Antes mesmo de partimos para a transferência de arquivos via LoRa, é preciso entender que o LoRa não foi feito para esse tipo de aplicação e sim para dispositivos IoT, mesmo embora tenha uma taxa…

The SX1262 is an updated LoRa chip, so we made a breakout 📡🔧🔄

We got a hot tip to check out the Semtech SX1262 (https://www.digikey.com/short/504bpwww) - compared to our classic SX127x series of "RadioFruit" boards (https://www.adafruit.com/product/3072) the '1262 has lower power usage and longer range as well as some more options for spread-spectrum and extra modulation protocols. Most folks will probably use it for LoRa / LoRaWAN. The pinout is slightly different, so a few changes were made to the classic PCB. We also had some extra room, so we tossed in mounting holes. With this design, you can use wire, uFL, or SMA antennas - just solder whichever connector you desire. Note that the new chips are not software-compatible, so some driver tweaks will be needed to make it work. Coming soon.

What is the difference between the LoRaWAN wireless module and LoRa gateway wireless transmission technology?

Many individuals find it challenging to differentiate between the LoRaWAN wireless module and LoRa gateway wireless transmission technology, as well as their applications within the realm of IoT.

LoRaWAN specifically pertains to the networking protocol found within the MAC (Media Access Control) layer. In contrast, LoRa serves as a protocol within the physical layer. Although current LoRaWAN networking implementations utilize LoRa as the physical layer, it's worth noting that the LoRaWAN protocol also allows for the use of GFSK (Gaussian Frequency-Shift Keying) as the physical layer in specific frequency bands. From a network layering perspective, LoRaWAN can adopt various physical layer protocols, just as LoRa can serve as the physical layer for other networking technologies.

LoRa, as a technology, falls under the category of LPWAN (Low-Power Wide-Area Network) communication technologies. It represents an ultra-long-distance wireless transmission method based on spread spectrum technology, pioneered and promoted by Semtech in the United States. This approach revolutionizes the previous trade-off between transmission distance and power consumption, offering users a straightforward system capable of achieving extended range, prolonged battery life, and increased capacity. Consequently, it expands the capabilities of sensor networks. Currently, LoRa predominantly operates within free frequency bands globally, including 433/868/915MHz, among others.

On the other hand, LoRaWAN wireless communication stands as an open standard defining the communication protocol for LPWAN technology based on LoRa chips. LoRaWAN defines the Media Access Control (MAC) layer at the data link level and is overseen by the LoRa Alliance. It's crucial to distinguish between LoRa and LoRaWAN because companies like Link Labs utilize a proprietary MAC layer in conjunction with LoRa chips to create more advanced hybrid designs, such as Link Labs' Symphony Link.

LoRaWAN typically employs a star or star-to-star topology, which is generally considered superior to mesh networks due to advantages such as conserving battery power and extending communication range. In a star topology, messages are relayed to a central server through gateways, and each end node can transmit data to multiple gateways. These gateways then forward the data to the web server, where tasks like redundancy detection, security checks, and message scheduling are executed.

In summary, LoRa encompasses solely the link layer protocol, making it suitable for point-to-point (P2P) communication between nodes. In contrast, LoRaWAN includes the network layer, allowing data to be sent to any base station connected to a cloud platform. By connecting the appropriate antenna to its socket, the LoRaWAN module can operate at different frequencies, offering versatility in its applications.

5G 12dBi Magnetic Antenna with RG174 Cable

A 5G 12dBi magnetic antenna is a type of antenna designed to enhance the performance of 5G wireless communication devices, such as routers, hotspots, or modems. Let's break down the key features:

5G: 5G is the fifth generation of wireless technology, which offers faster data speeds, lower latency, and greater capacity compared to previous generations (4G, 3G, etc.). The antenna is specifically designed to work with 5G networks and devices.

12dBi Gain: The "12dBi" figure refers to the antenna's gain, which is a measure of how much the antenna can increase the power of the signal it receives or transmits. A higher gain indicates better signal reception and transmission capabilities. In this case, a 12dBi gain suggests that this antenna can significantly boost the signal strength.

Magnetic Antenna: The term "Magnetic Antenna" indicates that the antenna can be attached to metal surfaces using a magnetic base. This feature provides flexibility in terms of placement and allows for easy positioning on metallic surfaces, like the roof of a car or a metal housing for a 5G device.

Magnetic antennas are often used in mobile applications or in scenarios where temporary or flexible mounting is required. This type of antenna is convenient because it can be easily installed and removed, making it suitable for mobile installations or where drilling holes or more permanent mounting solutions are not practical.

feather radiofruit prototypes showed up

these are two RP2040 'bones' boards that have an RFM69 900MHz module soldered in the empty spot, good for making basic wireless networks that have support for addressing and packeted data transmission. they can be transmitters or receivers, here both have the same code on them and when we press the user button on one feather, the opposite ones displays a message on the OLED with the RSSI. this makes it easy for me to verify the antenna quality. theres also a uFL antenna spot so we can connect big antennas using a uFL to SMA adapter - we covered finding these adapters on the Great Search this week! next up we will try RFM9x LoRa modules, those can run a LoRaWAN stack on the roomy RP2040 chip.
