NB-IoT and LTE-M Will Be the Backbone Communication Network for IoT in UAE

The IoT (Internet of things) is transforming and redefining all industries and markets. According to HIS (Information Handling Services), the IoT market is expected to grow to billions of connected devices over the years. These devices need Low-power wide-area networks (LPWAN) for data communication. In UAE (United Arab Emirates), the NB-IoT (Narrowband IoT) and LTE-M (Long Term Evolution Category M1) is gaining popularity as these networks are already provisioned by the telecom providers.

Today, LPWAN has cellular (licensed band) and non-cellular (unlicensed) technologies. Under the cellular category we have NB-IoT and LTE-M and in unlicensed, the popular categories are LoRa (Long Range) and SigFox (IoT Technology company and it uses the SigFox protocol). LoRa and SigFox need communication gateway which aggregate IoT sensor data to the IoT platform through their own private networks.

NB-IoT and LTE-M don’t need communication gateways and hence it is cost effective. These sensors communicate directly through the nearest base station of the telecom provider to their Cloud IoT platform. They both delivers low cost, low power and extended coverage with low data transmission capabilities. In UAE, they already have the coverage and ideally it makes sense to use either of them as the communication enabler. Also note that both are part of 5G journey and will coexist with 5G network. So, industries and customers can fully rely on them for IoT connectivity options. However, depending on the use cases and application scenarios, either one – NB-IoT or LTE-M needs to be chosen.

Some of NB-IoT use cases are Smart City, Smart Parking, Smart Metering, Street Lighting, Home Automation, Building Automation, Smart Agriculture, etc. The key requirements here are periodic transmission of small packets of data and longer battery life. These sensors rely on 4G coverage, so they work anywhere where there is coverage – even indoors. Moreover, for the above use cases, the IoT sensors are stationary, the network latency is between 1.5 to 10 seconds and amount of data being transmitted (peak data rate less than 100 kbps) is very less. The uplink/downlink speed is 27.2 / 62.5 kbps. The battery power consumption is best at very low data rate and can achieve battery life up to ten years. The NB-IoT uses narrowband, so it allows enhanced indoor and underground penetration and overall reach. So, a latency-insensitive sensor can be positioned in hard-to-reach areas which do not require high throughput or frequent reporting – idle for use cases like pipe-line monitoring, waste bin monitoring, man hole monitoring, etc.

For LTE-M, the use cases scenarios are – mobility, real-time data communication (for example emergency alarm data, voice, tracking) and mission-critical applications. Some use cases are Smart Transportation, Wearables, Smart Asset Tracking, Home Security, Patient Monitoring, etc. The LTE-M latency is between 50 to 100 milli seconds and peak data rate is 384 kbps. The uplink/downlink speed is up to 1 Mbps. LTE-M is idle when you need to meet user experience requirement for static and mobility scenarios. It also allows more data throughput compared to NB-IOT.

To recapitulate, the IoT application use cases will define which communication enabler fits best based on multiple parameters like existing telecom networks (with NB-IOT and LTE-M), standalone networks (LoRa and SigFox), static and/or mobility requirements, latency, data transmission rate, power consumption, battery life, components like gateways, controllers and finally the cost. As UAE already has the NB-IoT communication network, most of the IoT projects in UAE will be based on NB-IoT LPWAN as it will speed up deployments and more cost-effective in terms of capex and low operational cost. With flexible deployment as well as the possibility to implement OTA (over-the-air) firmware upgrades, many telecommunication operators across the globe has deployed NB-IoT and LTE-M. According to a new study conducted by Grand View Research, Inc the narrowband-IoT market size is expected to reach USD 6,020 million by 2025, registering a CAGR of 34.9% from 2019 to 2025. NB-IoT is booming.

I Sure Miss My Old Typewriter

I was going through my office the other day looking for something, and then I saw it for the first time in many years. It was my old typewriter.

Most people today have no idea what the typewriter is. I remember, however, my very first typewriter. I was so excited to get it and begin writing with it. I wrote a bunch of poems on that typewriter, and I sure wish I had copies of those poems.

Up until I got my typewriter, I was writing everything by hand, which can get very tiring after a while. There were typewriters in my school, and I went to a class to learn how to use a typewriter. However, I had no typewriter at home.

That Christmas, my parents surprised me with my very own typewriter. I was so excited about it, and I spent a lot of time typing nonsense. I used that typewriter for many years, and it was quite a companion with me.

Then I decided to upgrade to an electric typewriter. That was a significant upgrade for me. An afterthought: I wished I would’ve kept that first typewriter. When I got the electric typewriter, I could type faster than I was ever able to type before. I could not keep enough paper in the typewriter while typing.

Using those typewriters, you put in one sheet at a time, but since I knew nothing better, it was a wonderful thing. I went through a lot of paper.

In those old typewriters, what you typed was exactly what you got. If you mistyped a word, it was mistyped. I cannot remember how many times I yanked the paper out of the typewriter, put in a new piece and started typing all over again.

The thing so exciting was if I wanted several copies of what I was typing, I could use carbon paper between each page. What I typed on the first page was typed on the second and third pages. That sure was exciting because now I had copies of what I was typing.

The problem was, when I made a typo on the first page, it went all the way through to the last page. You could not fool those carbon copies. What was on one was precisely on the other.

I was thinking about that the other day and was wondering how I used up a forest of trees just learning to type.

That typewriter was a friend of mine, and we worked like a well-oiled machine. The thing about that typewriter, it never tried to correct me. It always went along with what I said and wrote – and never talked back to me. I was actually in charge.

I could always tell where my typewriter was because it was where I put it, and it never moved. To move that typewriter would have been a big job, and so it always remained on my desk in my room exactly where I put it. I could not take it traveling with me; I had to use it where it was.

At the time, I thought I had no better friend than that old typewriter of mine. To look at it now, I kinda smile as I remember how things have changed.

I was writing my first book, typing each page, when I learned about this new thingamajig called a computer. Well, I was not going to get anything modern. I was going to do things the old way. After all, Ernest Hemingway did all his typing on a typewriter.

The more I learned about these computers, the more interested I became. According to the people I was talking to, I could increase my output 100 times faster. I initially did not believe that.

Finally, halfway through that first book, I decided to switch over to a computer. Those first computers had no hard drive, so you had to put a floppy disk in to run any program that you might be using. You also had to save what you were writing to a floppy disk.

I set that new computer up in my office and started fiddling around with it to try to understand how it worked. Much to my surprise, the more I fiddled, the more I liked the music I was hearing.

I did not have to use paper until the manuscript was completed and I could print it out on a printer. If I made a typo, I could correct it right there on the screen, no problem.

Getting adjusted to it was difficult for me. I remember the first chapter I did and worked very hard to complete, but I forgot to save it on a disk and lost that whole chapter. I was a little provoked because my old typewriter would never have done that!

Through the years, I have regularly upgraded my computers to the point where I do not have to do much typing anymore. I can dictate into my computer and see words appear on the screen.

Looking at that old typewriter, I thought of what Solomon once said. “The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun” (Ecclesiastes 1:9).

Maybe the way I do certain things today has changed, but the message is always the same. Techniques change, but words never will.

Since 1997, Rev. James L. Snyder has written a weekly religion/humor column, “Out To Pastor,” syndicated to over 300 newspapers and many websites. The Rev. Snyder is an award winning author whose writings have appeared in more than eighty periodicals including GUIDEPOSTS. In Pursuit of God: The Life of A. W. Tozer, Snyder’s first book, won the Reader’s Choice Award in 1992 by Christianity Today. Snyder has authored and edited 30 books altogether.

James L. Snyder was given an honorary doctorate degree (Doctor of Letters) by Trinity College in Florida. His weekly humor column, “Out To Pastor,” is syndicated to more than 325 weekly newspapers.

How to Remove Spelling Errors From Your Document?

There is nothing worse than a document full of spelling errors. This reduces the credibility of your document. However, manually searching for spelling errors in a huge document is also a very overwhelming task. So do we have an option that can check our spelling errors fast and efficiently?

Yes. You can use online spell checkers.

Why use a Spell Checker?

The English language is very vast. It is not possible to remember all the words. It becomes even trickier with spellings. Even the most experienced writers make spelling mistakes.

Manually checking each word is not possible. It can be exhaustive. Suppose you wrote a 5000-word article. You cannot manually search for spelling errors in this article.

Moreover, humans are prone to errors. If you somehow manually checked an article there is no guarantee that your article is 100% correct.

This is where an online spell checker comes into the picture. They are fast, easy and effective in finding the errors in your article.

How does it Work?

There are three approaches that an online spell checker can use to check your document:

It can compare each word in your document with an online dictionary. This dictionary contains all the words in the English language. Any word in which the letters are misplaced will be edited as per the information in that huge online database.
Another way is to train your system to find the wrong word as per grammatical rules. It can mark “an” if you use “a” in words starting with a vowel sound. It can also use homophones to edit your article. Like wrong use of “write” in place of “right”.
The final way is to create rules for your own as per statistical data. This system employs a huge amount of data to frame its own rules to check spelling errors.
What Format can you use?
Most online checker can work with a variety of formats. Higher the number of formats it can handle, more popular and useful it will be.

The basic way is to copy your document and paste it into the online spell checker. This method is allowed by almost all the online spell checker.
Some platforms allow you to enter a URL that can be checked for all the spelling errors.
Many platforms will allow you to upload a.doc or.docx formats. It can be taken a bit further by allowing.pdf and.jpg formats as well.
Only a few online spell checker allows you to insert Google Docs and Dropbox URL.
What are the Benefits of a Spell Checker?
Using one spell checker has become necessary. It is used by school teachers to check the assignments submitted by their students. This helps them to grade the students quickly and saves a lot of time.

Broadly these online tools provide two benefits: firstly all the errors are removed without wasting time and secondly, it saves the effort required to proofread the article.

The best online tool for this purpose is Corrector. It can check your article and give you a list of errors in just 0.3 seconds. So, what are you waiting for? Just copy your text and paste it in this grammar checker.
