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.

What is the IoT? Everything you need to know about the Internet of Things right now

The essence of IoT is networking that student of Top Information Technology College should be followed. In other words, technologies will use in IoT with a set protocol that they will use for communications. In Communication, a protocol is basically a set of rules and guidelines for transferring data. Rules are defined for every step and process during communication between two or more computers. Networks must follow certain rules to successfully transmit data.

While working on a project, there are some requirements that must be completed like speed, range, utility, power, discoverability, etc. and a protocol can easily help them find a way to understand and solve the problem. Some of them includes the following:

1. The List

There are some most popular IoT protocols that the engineers of top engineering colleges in Jaipur should know. These are primarily wireless network protocols.

2. Bluetooth

Bluetooth is a wireless technology standard for exchanging data over some short distances ranges from fixed and mobile devices, and building personal area networks (PANs). It is invented by Dutch electrical engineer, that is, Jaap Haartsen who is working for telecom vendor Ericsson in 1994. It was originally developed as a wireless alternative to RS-232 data cables.

3. ZigBee

ZigBee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols that are used by the students of Best Engineering Colleges Jaipur to create personal area networks. It includes small, low-power digital radios like medical device data collection, home automation, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, ZigBee is a low data rate, low-power, and close proximity wireless ad hoc network.

4. Z-wave

Z-Wave is a wireless communications protocol used by the students of BTech information technology college in Jaipur primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance which allows wireless control of residential appliances and other devices like lighting control, thermostats, security systems, windows, locks, swimming pools and garage door openers.

5. Thread

A very new IP-based IPv6 networking protocol aims at the home automation environment is Thread. It is based on 6LowPAN and also like it; it is not an IoT applications protocol like Bluetooth or ZigBee. However, it is primarily designed as a complement to Wi-Fi and recognizes that Wi-Fi is good for many consumer devices with limitations for use in a home automation setup.

6. Wi-Fi

Wi-Fi is a technology for wireless local area networking with devices according to the IEEE 802.11 standards. Wi-Fi is a trademark of the Wi-Fi Alliance which prohibits the use of the term Wi-Fi Certified to products that can successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology mainly include personal computers, digital cameras, video-game consoles, smartphones and tablets, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet through WLAN and a wireless access point. Such an access point has a range of about 20 meters indoors with a greater range outdoors. Hotspot coverage can be as small as a single room with walls that restricts radio waves, or as large as many square kilometers that is achieved by using multiple overlapping access points.

7. LoRaWAN

LoRaWAN is a media access control protocol mainly used for wide area networks. It is designed to enable students of private engineering colleges in Rajasthan to communicate through low-powered devices with Internet-connected applications over long-range wireless connections. LoRaWAN can be mapped to the second and third layer of the OSI model. It is implemented on top of LoRa or FSK modulation in industrial, scientific and medical (ISM) radio bands.

8. NFC

Near-field communication is a set of communication protocols that enable students of best engineering colleges in Rajasthan two electronic devices. One of them is usually a portable device like a smartphone, to establish communication by bringing them within 4cm (1.6 in) of each other.

These devices are used in contactless payment systems like to those used in credit cards and electronic ticket smartcards and enable mobile payment to replace/supplement these systems. Sometimes, this is referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC is used for social networking, for sharing contacts, videos, photos, or files. NFC-enabled devices can act as electronic identity both documents and keycards. NFC offers a low-speed connection with simple setup that can be used by the students of top Engg colleges in Rajasthan to bootstrap more capable wireless connections.

9. Cellular

IoT application that requires operation over longer distances can take benefits of GSM/3G/4G cellular communication capabilities. While cellular is clearly capable of sending high quantities of data, especially for 4G with the expense and also power consumption will be too high for many applications. Also, it can ideal for sensor-based low-bandwidth-data projects that will send very low amounts of data over the Internet. A key product in this area is the SparqEE range of products including the original tiny CELLv1.0 low-cost development board and a series of shield connecting boards for use with the Raspberry Pi and Arduino platforms.

10. Sigfox

This unique approach in the world of wireless connectivity; where there is no signaling overhead, a compact and optimized protocol; and where objects are not attached to the network. Sigfox offers a software-based communications solution to the students of top engineering colleges in India where all the network and computing complexity is managed in the Cloud, rather than on the devices. All that together, it drastically reduces energy consumption and costs of connected devices.

SigFox wireless technology is based on LTN (Low Throughput Network). It is wide area network-based technology which supports low data rate communication over larger distances. It is mainly used for M2M and IoT applications which transmits only few bytes per day.

Amazon Sidewalk, the upside

*There is one, sort of, says Stacey Higginbotham.

Planning to reject Amazon Sidewalk? Do it for the right reasons By Stacey Higginbotham

Wow. This week, the media went after Amazon's distributed IoT network with a vengeance. Both the mainstream news and the tech press came out in force to recommend that people opt out of Amazon's Sidewalk Network before June 9th, when Amazon is due to turn it on. I, on the other hand, recommend that you opt in. There are really only four reasons to opt out of the network, and after I tell you a bit more about it, I hope you'll agree with me. If not, here's how to opt out. Let's get to it. Amazon designed the Sidewalk Network to provide a middle ground between home Wi-Fi networks and cellular coverage, with low-cost connectivity for devices that are out of Wi-Fi range but where cellular radios aren't a fit due to their cost, size, or battery needs. These Low-Power Wide-Area Networks (LPWANs) have attempted to gain ground for a decade as companies have tried to provide coverage for IoT devices. The biggest challenge in building these networks is cost, followed by power consumption. If someone wants to build a sensor that shares weather data a few times a day, it doesn't make sense to buy a cellular subscription or put an expensive cellular module into the device. But if they have access to cheaper connectivity, it opens up a world of possibilities. An inexpensive radio coupled with inexpensive data would mean the cost of running the device could be much lower and built into the cost of the product, which means we could see a lot of new products. Amazon's first floated its Sidewalk Network in September 2019 in its presentation about Ring products. At the time, Amazon SVP David Limp said Sidewalk could benefit Ring products by allowing them to be outside of the home Wi-Fi range. A year later, as its annual device launch event neared, Amazon explained how the network would work. And it said its Echo devices, certain Ring devices (Amazon owns Ring), and its Eero routers would contain sub-gigahertz radios that would support Amazon's new Sidewalk protocol. The network would use the Sidewalk protocol Amazon developed over radios that use the same frequency as LoRa networks to send small packets of data up to half a mile. (Amazon has said the protocol will work over Bluetooth as well.) The mesh network would then transmit those packets back to the internet through its customers' broadband networks. Jamie Siminoff, the CEO and founder of Ring, has likened it to borrowing a cup of sugar from your neighbor. Amazon subsequently sent its executives out on press tours to explain the safeguards associated with the Sidewalk Network. Amazon would only siphon up to 500 MB a month (that's half a gigabyte), they noted; in the meantime, the company released a paper explaining how the Sidewalk protocol worked from both a security and privacy perspective. It's really important to note that Amazon cannot see the packets sent over the network, nor can it see how those packets are routed. Ken Goto, the CTO of Level (podcast), which will use the Sidewalk Network for connectivity inside its smart lock, described the data as a wrapper, wrapped in a wrapper, wrapped in another wrapper. Level is using the Sidewalk network to avoid building Wi-Fi in its smart locks. According to Goto, the lock only has Bluetooth and a Zigbee radio, so Level can save on cost and battery consumption. But that means when the lock is outside of a phone's Bluetooth range, it needs another way to connect back to the lock. With the Sidewalk Network, Level's requests can use Bluetooth to get on the Sidewalk mesh and then back to the Internet, where the app can communicate with the distant lock. This is a pretty sweet use case, and it eliminates the ever-present bridges many homes have today to connect Bluetooth devices back to Wi-Fi and the internet. I firmly believe that this network will be an overall benefit for consumers and developers, who can add new features or build new, cheaper devices that take advantage of it. The privacy and security features are legit. Again: Amazon doesn't see your data and it doesn't see the developers' data. Neither does anyone else. In other words, I think you should opt in. I can only see four reasons that someone would want to (or should) opt out of participating. 1. You are on a metered data plan with a low data cap. For people in rural areas or those running their Amazon devices on a metered plan with a low cap, losing up to 500 MB a month might be too much to countenance (although this amount is not likely to be reached in a super rural area without a lot of participating devices). 2. You're a control freak. When talking to a few tech nerds about this — and after getting them to admit that the security protocols looked pretty good — most came to the conclusion that they simply don't want their home network to be used as a bridge for unknown packets. What if those packets were illegal? What if the ISP didn't permit that type of use? I can't argue with control freaks, but I can point out that Apple's AirTags and FindMy network run on a similar principle of using your home or cellular data to share Bluetooth location data across an ad-hoc mesh network. 3. You want to hold out for more. Another common complaint about Sidewalk is that by automatically opting people in, Amazon is getting a network for nothing, and it's using your bandwidth to do it. I get why that pisses people off and I don't like it, either. But it's doing it because it's hard to build a wireless network and get devices on that network unless there's already widespread coverage. And getting widespread coverage is also hard. So is asking people to opt in, because people are lazy. I think Amazon should provide a decent incentive (like a digital credit for a free movie) to get people to opt in. So if currently you're not opposed to joining the network but want something in return, maybe if you opt out now Amazon will feel the loss keenly enough that it offers you something. 4. You hate Amazon and don't want to give it any more power. There are plenty of people who distrust Amazon and appear to have reacted to the Sidewalk news as another opportunity to drag the company — even while still using the Amazon Alexa or Ring devices that would put them in danger of participating in the network. Whereas if you truly distrust Amazon, you probably aren't in danger of becoming part of this network because you won't have the devices. So if you have the devices and opt out because you don't trust Amazon, ask yourself why you are still giving it so much space in your home and so many dollars from your wallet. I've covered wireless networks for almost two decades, so I understand better than most that Amazon is usually a data-vacuuming, self-interested entity that has historically not cared about privacy or its workers. And the Sidewalk Network will benefit Amazon. But not by letting the retailer suck up your data, or device data from its competitors. Amazon is building this network because there is a genuine need for a cheap IoT network with long-range coverage. And because that is something that we all need, I'm eager to participate. I hope most of y'all will, too. Listen to this week's podcast for more on this topic.
