Here's Why You Should Use 5GHz Wi-Fi Band in Place of 2.4GHz

 Wi-Fi networks use radio signals, it transmits at frequencies of 2.4 GHz or 5 GHz. Each frequency band has its advantages and disadvantages, and we will see which is the most convenient to use depending on your situation, speed, distance, and device.

All modern Wi-Fi devices support 2.4 GHz connections, while some supports both frequency band. Home broadband routers that feature both 2.4 GHz and 5 GHz radios are called dual-band wireless routers.

An important distinction to make is between a WiFi network and your mobile phone's wireless network. These are two very different technologies, and it can become even more confusing when you discuss 5 GHz WiFi frequency band and 5G mobile networking technology, the replacement for 4G.

5G & 5 GHz Are Different: Here's What They Mean
Here we will discuss WiFi networking that you can set up in your home using a router, and the two frequency bands used and how a dual-band home network can be set up to take maximum advantage of the best of both frequencies. This does not cover mobile networking technology for smartphones and other devices.

GHz and Network Speed
WiFi networking comes in a few varieties. These WiFi standards define improvements in networking technology. The standards are (in order of release, oldest to newest):


These standards are connected to GHz band frequencies, but these aren't discussed in great detail here, but they are referred to.

A 5 GHz network can carry more data than a 2.4 GHz network and so technically are faster (assuming the electric power to the higher frequency radio is maintained at a higher level). 5GHz radios support significantly higher maximum data rates in network standards 802.11n and 802.11ac. Home devices that generate or consume the largest amount of network traffic, like video streaming units or game consoles, generally run fastest over 5 GHz links.

GHz and Network Range
The higher the frequency of a wireless signal, the shorter its range. 2.4 GHz wireless networks therefore cover a substantially larger range than 5 GHz networks. In particular, signals of 5 GHz frequencies do not penetrate solid objects nearly as well as do 2.4 GHz signals, limiting their reach inside homes.

GHz and Network Interference
You may notice that some cordless phones, automatic garage door openers, and other home appliances also use 2.4 GHz signaling. Because this frequency range is commonly used in consumer products, it's become saturated with signals. This makes it more likely that a 2.4 GHz home network will suffer interference from appliances than will a 5 GHz home network. This can slow down and interrupt WiFi network speed in these cases.

All these interferences do not affect the 5 GHz being very far from that band, which also has the advantage of being able to send data through several channels at the same time. Thanks to all this, a 5 GHz signal is more stable and reliable, but in general, it has a shorter range. Therefore, using the 2.4 GHz Wifi has only one advantage: that it reaches a greater distance if the router is several tens of meters away from our device, or if there are walls in between.

With this, we have the 2.4 GHz WiFi from the 2.412 MHz bands (channel 1) to the 2.472 MHz (channel 13), where there is a new channel in every 5 Mhz. Each channel covers up to 22 MHz, where they overlap each other, hence, in the case of the 5 GHz WiFi, there are 21 channels of 20 Mhz each, wherein that space none overlap each other.

The actual maximum speed reached by the 2.4 GHz coverage is about 150 Mbps (theoretical 300 Mbps), while at 5 GHz it reaches speeds that vary between 200 Mbps and 1 Gbps, with theoretical maximums of 433 Mbps and 1 or 7 Gbps.

However, the fact is that the most modern routers can now join both networks into one, in such a way that it automatically decides which network is the most convenient to use at any time, automatically changing our device between them. This is possible simply due to the features like Intelligent WiFi, present in routers such as the premium WiFi Repeater.

Even if they do not have Intelligent WiFi, almost all current routers create two networks, and the mobile automatically connects to the 2.4 GHz one if we are connected to the 5 GHz and we are left without coverage.

You can also give the same name and password to both networks, although this may not work with all devices. You should bear in mind that some of your old devices may only work with 2.4 GHz Wi-Fi, as on the smartphones more than 5 years ago.

GHz and Cost
Some people mistakenly believe 5 GHz network technology is newer or somehow more innovative than 2.4 GHz because 5 GHz home routers generally became available after those that use 2.4 GHz radios. In fact, both types of signaling have existed for many years and are both proven technologies.

Routers that offer both 2.4GHz and 5GHz radios are generally more expensive than those offering only 2.4GHz radios.

Microsoft Will End Windows 7 Support by Early 2020

The Redmond Software giant, Microsoft, has announced that its support for Windows 7 will end after January 14, 2020. In essence, Windows 7 users will no longer receive updates or security fixes after the said date.
“All good things must come to an end, even Windows 7.”

Windows 7 has been applauded as the best version of Windows, after Windows XP. At its one year anniversary in 2010, Microsoft’s Brandon LeBlanc blogged that more than 240 million Windows 7 licenses were sold that year, making it the fastest-selling operating system in history. Even after the release of Microsoft’s elegant Windows 10, Windows 7 still ruled the market. It took a few years before 10 started getting fair market share.

Some of the features that greatly improved the general user experience of Windows was first seen on Windows 7. The OS brought the ability to pin items on the taskbar, and refined the look and feel of Windows with Aero Interface.

While Windows 7 wasn’t exactly overloaded with fancy features, it brought stability, good networking and enhanced security to the Windows landscape, especially after its predecessor – Windows Vista, received much criticism for its poor performance.

Current Windows 7 users have about a year before Microsoft cuts off their supply of security fixes. Microsoft will, however, continue to provide updates to Windows 7 enterprise customers who’d pay for support.

Should you decide to continue using Windows 7 after its end of support date, Microsoft warns that your PC will become vulnerable to security risks. Users of 7 are advised to upgrade to Windows 10. Even better, one should purchase a new Windows 10 PC in order to enjoy the latest hardware capabilities.

Tip of the Day: Know Which Network Each Mobile Phone Number Belongs To

Mobile Network
The first GSM service was rolled out in Nigeria in August 2001. A little under two decades later, the number of SIMs issued by network operators has grown so much so that it’s almost impossible to associate numbering schemes to their respective operators. Back then it was quite easy to know which number prefix belonged to which network. For instance, any number starting with 0803 belonged to MTN, 0805 Glo, 0802 Airtel, and so on. But due to the explosion of mobile telephony across the country, it’s almost become a chore to know which numbers are associated with each network.
The Nigerian Communications Commission is responsible for the development of the National Numbering Plan. It publishes a list of the numbering schemes on its website and makes it available to the public. You can find the exhaustive list containing all the operators in Nigeria here. The list contains other operators like Smile, Visafone etc.
The table below shows the phone number prefixes for some of the major Telco operators in Nigeria:
Even though people are now being able to port their numbers from one operator to another using Mobile Number Portability, the number of ported numbers aren’t too many. It’s safe to say the overwhelming majority of numbers still belong to the telcos that originally issued them.
You can also discover other useful statistics on mobile number allocation and management from the NCC website.

4 Ways Technology Impacts Tourism and Travelling in Nigeria.

Today, technology affects every aspect of life, including travels and tourism. With the introduction of the Android phones and mobile network upgrades from 3G to 4G, and possibly now 5G, the tourism scene in Nigeria is being impacted.
mobile phone
1. Improve Our Travel Options
Before, we would have to go to a physical location to book a flight, hotel room or make reservations in advance. But these days we can do that from the comfort of our homes. We can even compare prices and book holiday tour packages via the internet with websites like Wakanow, Travelstart Ng,, etc. Plus, we now have access to a range of hotel options with pictures and where their property is located, a list of their services and prices. We can also choose the bus seat and time of travel from road transport companies through their website e.g. God Is Good Motors or Chisco Transport. We can use some travel Apps on our mobile devices to make travel easier like Google Maps, abokiFX, Oanda currency calculator, Uber/Taxify, etc.

2. Keep Communication Lines Open
In the 80s and 90s, we needed landlines and telephone operators to keep in touch. But these days, we have mobile phones that allow us to receive calls wherever we are with no need for a phone booth or having to run back home. We also have Messaging Apps like Facebook Messenger and Whatsapp; Video calls Apps like Skype or Facetime. And Social Media Apps to share picture updates to friends and family on your travel progress like Instagram, Facebook, etc. So Communications are no longer just audio, they can be visual and real time too.

3. Have Easier And Secure Payment Options
Nowadays, we don’t have to travel around with bulk money in our pockets, wallets or suitcases. Just a few bank-cards like a credit or debit card and we are ‘good to go’ if the recipient has a POS or there is access to an ATM for a quick withdrawal. Banks also have mobile Banking Apps and AI like Leo who can help manage money transfers without the need to set foot in a banking hall. If the move towards a cashless society had panned out, we would have electronic payment systems that use Apps like Google wallet, Bitcoin payment, Samsung pay, etc.

4. Create More Personalised Travel Experiences
We capture memories with selfie sticks and our high-resolution Smartphones if we can’t afford a DSLR camera. Thereby allowing us to document our travel experience.  We can also now catch up with News or Entertainment on the go as most TV stations now have Apps with streaming services like Kwese TV, Channels TV, DSTV Now, etc. For now, we are yet to use Augmented Reality to sell tour destinations so people can get a feel of experience they are buying into. Or use translator Apps like iTranslate to break language barrier in certain parts of Nigeria (since we are a country with over 250 languages).

There are so many amazing technologies out there that are yet to be implemented in Nigeria. But as we catch up with the new technological advancements, we will continue to feel it impacts in our national Tourism sector.

Top 7 Mobile Photography Tricks

“A good photograph is one that communicates a fact, touches the heart and leaves the viewer a changed person for having seen it. It is, in a word, effective.”
— Irving Penn
Great images are not made by cameras but by people. There’s a whole lot to taking good pictures than just having a nice camera or smartphone. There are one or two things one needs to take cognisance of, and a few other pro photography tricks that can be employed to take good pictures on a smartphone.
Let’s take a look at a few smartphone photography tips you should know.

Clean Your Camera Lens

This might just be the most overlooked routine when taking pictures. Chances are that while using your phone, you must have smudged the camera lens with your fingers which will make it dirty and greasy. A dirty lens will block light from entering the camera’s sensor effectively and will lead to poor, blurry images. A clean lens will ensure you get crisp, clear images with your phone.

Light Is Your Best Friend (But Not The Flash)

You need to take advantage of natural light sources, and also pay attention to the light source. Make sure the light source is not behind your subject, rather it should be in front so as to light up the subject.

Use The Rule Of Thirds

The rule of thirds suggests that you divide your camera viewfinder into a set of 3×3 cells so that you have 9 parts. You can do this by enabling the camera grid on your smartphone. With this grid in mind, you can better compose your images by positioning your subject at the intersection points of the grid lines.

Focus With The Viewfinder

Always tap the viewfinder to focus on the subject you are trying to capture. This will make for sharper images.

Get Close To Your Subject

If you are taking portrait shots, get close to your subject. The portrait feature in recent smartphone cameras works much better when you capture the picture close up.

Shoot Along Lines

Shooting along lines can lead to breathtaking images. You can practice this by taking pictures along wall lines, bricks or tiles, staircases, or a building’s grid. Lines enhance a sense of depth in photos and emphasise your subject.

Get A Better Camera App

If your camera app is not feature-rich, get another camera app that will allow you more control over things like exposure compensation, white point, shutter speed, ISO, etc. Some camera apps also have better image processing than others.

Tip of the Day; How to Use the New Windows Clipboard

Microsoft Clip
Copy and paste is arguably one of the most used software features on mobile and desktop devices. This is because people are always transferring information (usually text and images) from one field to the other, or one app to the other. The copied items are held in a clipboard so the user can easily paste it wherever.
Microsoft in its October 2018 update introduced a new and refined clipboard. The new clipboard stores copied content (up to 4MB), allowing you to view and paste them from the clipboard history. This is averse to the old method that only supported copying one piece of content at a time and had no interface where the copied items can be viewed.
In addition to displaying your copied items, the clipboard also syncs and makes your data available and accessible across all your devices.

How To Use:

Clipboard adds a new keyboard shortcut to the popular Ctrl C + Ctrl V combo. You can now use the Windows key + V shortcut to bring up the new clipboard history. You’ll find a list of items (such as text and images) that you have copied from different applications (Microsoft Word, OneNote, PDF, etc) in the Clipboard interface.
To  use clipboard, you first need to enable it from the Settings app. Follow the steps below.
  • Go to  Settings >> System >> Clipboard.
  • Turn on the Clipboard history toggle switch.
Alternatively, you can enable Clipboard when you use the Windows key + V keyboard shortcut. If Clipboard history is off, you’ll be asked to turn it on.  Just click the Turn on button.
Then, to copy and paste content from your history, follow these steps:
  • Select the text or image you want to copy.
  • Use the CTRL C or CTRL X shortcut to either copy or cut, or right-click the selection and click the Copy or Cut option.
  • Open the document or filed you want to paste the content in.
  • Use the Windows key + V shortcut to open the clipboard history.
  • Select the content you wish to paste and click on it. Your cursor must be placed in the field where you want to paste the item.
You can also pin the items that you wish to reuse.
  • Use the Windows key + V shortcut to open the clipboard history.
  • Click the Pin button at the top of the content to pin it.
  • When you no longer need the content, click the button again to unpin or the X button to delete the item.
Clipboard doesn’t yet support copying of non-text or non_image files. Also, the cloud clipboard only supports images copied within a document and disregards image files copied from file explorer or the web browser.
Clipboard history is only accessible on computers running Windows 10 version 1809 or later, and the same Microsoft account must be signed in on them.
Anyone using clipboard must be careful when dealing with sensitive content like passwords and personal info. You must be sure to delete such data as anyone that gets a hold of the computer will be able to view the information by just using the Windows key + V shortcut.
To clear clipboard data,
  • Go to  Settings >> System >> Clipboard.
  • Under Clear clipboard data, click the Clear button.
Enabling sync for clipboard means your history will be uploaded to Microsoft servers. You should disable sync if you do not want to expose any sensitive data.
To turn off sync,
  • Go to  Settings >> System >> Clipboard.
  • Under Sync across devices, turn off the toggle switch.

Microsoft’s latest feature could save users from startup failures after installing Windows Updates

Windows users have a love-hate relationship with Windows Updates. This is mainly because they keep running into issues after installing updates. It looks like Microsoft has also taken note of the issue and has added a safety measure for the same.
According to a new document published by Microsoft (via Windows Latest), Windows will now automatically uninstall updates if a user runs into startup issues. Due to the sheer number of devices running on Windows, it’ important to have a safety mechanism in place for when things go wrong. If something does go wrong, Windows will boot up the device and uninstall Windows Update.
Not only that, if this happens, Windows will automatically block Updates for the next 30 days so Microsoft can investigate and fix the issue before the update is delivered to the user again.
To ensure that your device can start up and continue running as expected, Windows will also prevent problematic updates from installing automatically for the next 30 days. This will give Microsoft and our partners the opportunity to investigate the failure and fix any issues. After 30 days, Windows will again try to install the updates.
Microsoft does allow users to manually install updates if they think that the rollback was a mistake or if Microsoft fixes the issue before the 30 day period is over. Lastly, Microsoft also asked users to share Feedback using the Feedback Hub so the company can take a look at the diagnostic data and work on the fix accordingly.
