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.

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.

[ad_1] If you've been following our Meshtastic hardware reviews, you've likely seen our recent coverage of the WisMesh Board ONE Pocket - RAK's handheld Meshtastic device. Today, we're examining the heart of that system: the WisMesh Board ONE bare board itself.Unboxing and Initial ImpressionsThe WisMesh Board ONE arrives in simple but secure packaging. Inside, you'll find:The main WisMesh Board ONE baseboard1 LoRa antenna (FPC base antenna)1 high-quality USB cableDepending on your configuration, you might also receive:Optional OLED 1.3" display (pre-mounted or separately)Optional RAK12500 GNSS moduleThe board itself makes an immediate impression with its thoughtful layout and compact form factor. At just 60.8 x 22.9 x 9.85 mm, it packs impressive functionality into a small footprint. The PCB quality is excellent, with clean traces and robust component mounting.Features OverviewThe WisMesh Board ONE comes with several notable features:RAK4631 Core: Based on Nordic nRF52840 (ARM Cortex-M4F CPU, 1MB Flash, 256KB RAM)Semtech SX1262 LoRa transceiver1 WisBlock sensor slot for expandability (occupied if GPS module installed)Optional 1.3" OLED display - noticeably larger than common 0.96" screensImproved BMS (Battery Management System) with NTC for safer charging and dischargeSolar & Battery connector - strategically positioned for optimal enclosure designThree mounting holes for secure installationExternal iPEX connector - for antenna upgradesUSB-C for power and programmingWhat makes this board particularly interesting is how it improves upon RAK's previous RAK19007 design with specific optimizations for solar-powered and fixed deployments.Configuration Options & PricingThe WisMesh Board ONE is available in several configurations:Base Board Only: $29.97With RAK12500 GNSS Module: $50.97With GNSS Module & OLED Display: $52.97This tiered pricing lets you select only the components needed for your specific project.Flashing the FirmwareThe device comes preflashed with Meshtastic version 2.5.20, but if you want to update it, here's the process:Erase the Existing Firmware:Navigate to the Meshtastic Web Flasher.Select RAK WisBlock 4631 from the device options.Click on the trash symbol next to the flash button to erase the existing firmware.You'll need to enter DFU mode (Device Firmware Update mode) to proceed.Entering DFU Mode:Option one: Double press the button on the right (the one used for reset) and a USB drive should show up on your computerOption two: Click on Enter DFU Mode (After Clicking on Flash and Continue), select the correct COM Port, then click Connect.Erase the Flash in DFU Mode:Once in DFU mode, the WisMesh Board ONE Pocket will appear as a drive on your computer.Download the Flash Erase UF2 file and copy it to the DFU drive. After transferring, the drive will disappear.Once the device is done rebooting, go back to the web flasher and click on Open Serial Monitor, select the correct COM Port, then click Connect.Give it a couple seconds and it should say done once it is done formatting.Flashing the New Firmware:After erasing the existing firmware, return to the Web Flasher and choose the latest firmware version available.Select Flash, and you will need to enter DFU mode again (repeat the previous step).Once in DFU mode, download or copy the UF2 file for the new firmware onto the DFU drive.The device will automatically reboot once the transfer is complete and will start running the new firmware.Detailed Comparison: WisMesh Board ONE vs. RAK19007For Meshtastic enthusiasts and solar node builders, the RAK19007 has been a popular choice since its release. I was eager to see how the WisMesh Board ONE improved upon this foundation. Here's a comprehensive comparison of these two solar-optimized boards:Core Specifications Comparison FeatureWisMesh Board ONERAK19007CPUNordic nRF52840Nordic nRF52840LoRa ChipSemtech SX1262Semtech SX1262Size60.8 x 22.9 x 9.85 mm64 x 20 x 12 mmExpansion1x WisBlock Sensor Slot4x WisBlock Sensor Slot 1x IODisplayOptional 1.3" OLEDOptional NA" OLEDAntennaiPEX connectoriPEX connectorBase Price$29.97$29.99 While the core specifications remain similar, the WisMesh Board ONE introduces three significant design improvements that address specific pain points experienced with the RAK19007:1. Reimagined OLED Display PlacementOn the RAK19007, the OLED display connector was positioned 90 degrees to the board. This created one main problem:The screen was at an angle that made reading information difficultThe WisMesh Board ONE completely reimagines this arrangement, mounting the OLED display 180/0 degree/s to the board. This redesign:Improves screen readability when mounted in a case2. Strategic Battery and Solar Connector OrientationThe RAK19007's battery and solar connectors were positioned on the top face of the board. While functional, this arrangement created consistent headaches for enclosure design:Cables had to bend awkwardly, adding unnecessary heightStrain on connectors increased with compact enclosuresThe WisMesh Board ONE addresses this directly by repositioning these connectors to the side edge of the board, which:Enables much flatter enclosure designs (potentially reducing case thickness by 5-10mm)Creates a natural cable path that reduces connector strain3. Enhanced Battery Management SystemThe RAK19007's battery management was functional but basic. The WisMesh Board ONE significantly upgrades this with:NTC thermistor on the board for simplified buildsSupport for external NTC connection for batteries with built-in temperature sensorsBetter protection against overcharging in variable solar conditionsPerformanceBattery Life: Real-World ConsiderationsThe board's power consumption is in line with what you'd expect from nRF52840-based devices. It's important to note that adding the optional OLED display does increase power consumption significantly, making it less ideal for pure power efficiency.Range & Connectivity: Upgradable and AdaptableThe included FPC antenna provides pretty solid range from 800-1000 meters if you angle towards your receiving node. it’s was really competitive with something like Sensecap T1000E. If you plan to build a small sleek node, it would definitely perform well, but the real strength lies in the upgrade path:The iPEX connector allows for connecting any LoRa antenna via an adapter cableWith a quality external antenna, range extends dramaticallyThis flexibility makes it suitable for both urban and rural deployments. This upgradability gives the WisMesh Board ONE a significant advantage over fixed-antenna designs like the T1000-E.WisBlock Sensor Slot: Limited But ValuableOne key difference from the RAK19007 is that the WisMesh Board ONE includes just a single WisBlock sensor slot (compared to four on the RAK19007). This modular expansion system allows you to:Add environmental sensors (temperature, humidity, pressure)Monitor air qualityAdd many other capabilities through the extensive WisBlock ecosystemThe plug-and-screw design makes sensor swapping incredibly easy – just one screw secures the module in place.Market Positioning: The nRF52 Board LandscapeLooking at the market for bare boards based on nRF52, we can see several options, each with their own tradeoffs:Heltec T114: After their recent quality control issues, user trust has eroded significantlyWio Tracker 1110 Dev Kit for Meshtastic: Huge size with no solar supportXIAO nRF52840 & Wio SX1262 Kit: Fairly new and without a full BMS; however, with time it might start supporting the expansion boards used for XIAO ESP32S3 & Wio-SX1262 Kit that adds BMS, screen, and groove connectors for sensorsIn this landscape, the WisMesh Board ONE hits a very sweet spot within the RAK ecosystem. Both the RAK19007 and WisMesh ONE are priced the same, but they serve different needs:RAK19007 StrengthsFor solar nodes that need multiple sensors (like weather stations), the RAK19007 offers more expansion slots. While you don't get the NTC feature, it is field-tested with good reliability overall despite occasional issues.WisMesh Board ONE StrengthsThe WisMesh Board ONE shines as a versatile board for:Ultra-compact solar nodes with really good BMS, NTC capabilitiesSmall handheld devices with properly integrated displays - something RAK was missing with the 19007 due to screen orientation issuesProduct Positioning: Where It FitsAt $29.97 for the base board, the WisMesh Board ONE is priced identically to the RAK19007, yet offers fewer expansion slots. So what's the value proposition?The WisMesh Board ONE appears to be targeting a specific niche: optimized form factor and improved power management for standalone solar-powered deployments or very small and sleek handheld builds, especially where a low-profile enclosure is desired. It trades expansion slots for:A more thoughtful physical layout optimized for enclosure designBetter battery management for solar applicationsDedicated screen connector with improved positioningOverall slimmer profile for compact enclosuresThis makes it particularly well-suited for fixed installations/builds where a clean, reliable deployment is more important than having multiple sensors. For deployments that need multiple sensors, the RAK19007 remains the better choice despite its design limitations.Final Thoughts: Market Positioning and Value PropositionThe WisMesh Board ONE represents an interesting evolution in RAK's Meshtastic board lineup, with some clear improvements over the RAK19007 but also some significant tradeoffs.Improvements Worth NotingBetter BMS with NTC support: Enhanced battery management makes solar deployments safer and more reliableOptimized connector positioning: Better angled solar and battery connectors reduce enclosure thicknessProperly oriented display: The 180/0-degree screen mounting significantly improves usabilityCompact, low-profile PCB: At just 60.8 x 22.9 x 9.85 mm, it's ideal for space-constrained deploymentsThe Major TradeoffDespite these improvements, the WisMesh Board ONE reduces expansion capability from four WisBlock sensor slots to just one - yet maintains the same $29.97 price point as the RAK19007. This creates a curious situation where you're paying the same amount for less expandability, albeit with better design.The Strategy Behind the DesignThis product's positioning becomes clearer when considering RAK's market observations. The RAK19007 unexpectedly became popular for handheld builds despite its solar connections and awkwardly angled screen - many builders simply avoided using the display altogether. RAKwireless appears to have recognized this pattern and created a board specifically optimized for two use cases:Ultra-compact solar nodes with minimal sensor requirementsSmall handheld devices with properly integrated displaysRecommendationFor users with very specific requirements matching these use cases, the WisMesh Board ONE is an excellent fit. However, for general-purpose deployments, we can't broadly recommend it over the RAK19007:For solar nodes: The RAK19007 offers more expansion slots if you need multiple sensorsFor handhelds with screens: The WisMesh Board ONE stands alone as the only reliable NRF52-based option with proper screen support and quality BMS (especially since Heltec's reputation suffered after recent quality issues with T114)Ultimately, the WisMesh Board ONE fills a niche but important gap in the market. Rather than seeing it as a replacement for the RAK19007, it's better viewed as a specialized alternative for specific deployment scenarios where its design improvements outweigh the reduction in expansion capability.If someone were to design an enclosure that is wider rather than taller, where we can use the RAK19007 with the screen oriented the correct way, would the WisMesh Board ONE still be a point of interest? Are the smaller footprint of the PCB design, NTC capabilities, and better oriented plugs alone enough to sacrifice the expansion slots? Let us know your thoughts in the comments below.

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.

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.
