Be cautious with WiFi: Public wireless networks and hotspots are not secure, which means that anyone could potentially see what you are doing on your mobile device while you are connected. Limit what you do on public WiFi, and avoid logging in to key accounts like email and financial services on these networks. Consider using a virtual private network (VPN) or a personal/mobile hotspot if you need a more secure connection on the go. 

Keep your mobile apps updated: Your mobile devices are Justice as vulnerable as your PC or laptop. Having the most up-to-date security software, web browser, operating system and apps is the best defense against viruses, malware and other online threats. 

Delete when done: Many of us download apps for specific purposes, such as planning a vacation, and no longer need them afterwards, or we may have previously downloaded apps that are no longer useful or interesting to us. It’s a good security practice to delete all apps you no longer use.

Be cautious, you being watched

 Whether you believe it or not but the truth of the matter is that you are being watched or spied on your cellphone.


This is done mostly by Government agencies, technically for a good cause, which turn to be a disaster sometimes. These agencies does this for security purposes in most of the cases and to protect the innocent individuals from the criminal activities done via cellphones. Believe me most of the the missing individuals are found by tracking them through their cellphones. Well known and wanted criminals are mostly arrested by tracking their cellphones activities.


You are not only being watched by Government agencies, software companies and hackers are watching you too. This is where the problem and issues start because both hackers and these companies are not hire to protect you but they all after your personal information and data. Software companies uses your personal data and information to gain profit as they sell you to the third parties such as insurance companies and retail stores.

First of all almost all smart phones comes  from the factory pre-installed with certain softwares, mostly Google softwares such as play store, Google maps and others.

WIFI 6

 Albeit distant work isn't new, the Covid-19 pandemic unquestionably sped up its selection to where it has become the new reality.

With the third wave grasping South Africa among different nations, representatives all throughout the planet are acknowledging they may be telecommuting for quite a while as yet, which means gatherings held by means of video conferencing and occasions facilitated as online classes might be the standard for a long time.

"Doubtlessly that far off work is setting down deep roots," says Nyeleti Shikwambane, Huawei item director at Pinnacle. "Indeed, we can hope to see considerably more individuals done working just from the workplace and moving between an assortment of areas, some of the time telecommuting, at times from the workplace, once in a while even from cafés and other public spots."

In any case, while the world has adjusted splendidly to this new worldview, distant working actually goes inseparably with a few concerns. Business pioneers are stressed over security, perceivability and consistent interchanges, however these aren't first spot on the list. What is central is organizing and availability, as workers can't manage their responsibilities successfully in the event that they come up short on the network and framework to do as such.

"Independent of whether experts are telecommuting or from the workplace, they anticipate similar help and levels of administration from their association and other innovation, and should be certain that their tech office will uphold them regardless of where they are," says Shikwambane.

Thus, she says IT groups are searching for approaches to further develop availability, and they need look no farther than WiFi 6. "Individuals stress over restricted transfer speed, and dropping associations in the event that another person at their house is occupied with transmission capacity hefty exercises. They likewise stress over their association going down, especially in the event that they are in a significant assemble or conference, maybe even one with the board or other C-level chiefs. This can be an enormous issue."

"WiFi 6 proposals obviously better excess," Shikwambane adds. "It implies clients don't have to rely upon a solitary work association and ensures that they can stay useful, appreciate continuous network and the right versatility."

She says as innovation advances and improves and better, each new age of WiFi guarantees a superior encounter for its clients. "Let's be honest, WiFi 6 couldn't have occurred at a superior time. It's various advantages and advances are ideal for setting up home organizations for clients that can without much of a stretch adapt to the traffic of WebEx, Google and Zoom gatherings, just as close to home uses like streaming and other online diversions."

Digging further into the advantages, Shikwambane says perhaps the most encouraging is the quicker speed that WiFi 6 offers. "WiFi 6 is equipped for a greatest throughput of 9.6 Gbps across different channels, a lot quicker when contrasted with 3.5 Gbps on WiFi 5."

In principle, a WiFi 6 able switch could hit speeds more than 250% quicker than current WiFi 5 gadgets, notwithstanding, switches only here and there help the quickest velocities conceivable, so clients ought to deal with their assumptions."

Another advantage, is upgraded security, she says. "Especially with the Protection of Personal Information Act happening in a couple of days, security is a greater issue than at any other time. Add to this the endlessly more extensive assault surface that organizations need to manage on account of having their labor forces spread out all over because of the pandemic, and it's straightforward why security is a worry."

In any case, WiFi 6 settles this issue, and associations in each industry can have confidence that their protected innovation and delicate data are free from any and all harm, as Wi-Fi 6 gadgets must have the option to help WPA3 security conventions, Shikwambane clarifies. WPA3 utilizes a framework known as Wi-Fi Device Provisioning Protocol which empowers clients to utilize NFC labels or QR codes to permit gadgets on the organization. In addition, WPA3 security utilizes GCMP-256 encryption, which is much better than the 128-digit encryption utilized previously.

Then, at that point, she says, there's the subject of expanded limit. "As I would like to think, this is presumably the most convincing advantage of WiFi 6. It's anything but about speed, yet limit, and when you have numerous clients, with different brilliant IOT gadgets that are for the most part competing for space and interfacing with a solitary organization, then, at that point Wi-Fi 6 is a friend in need.

WiFi 6 innovation opens more channels to oblige undeniably more information traffic, by parting a remote channel into a lot more sub-channels. This is known as Orthogonal Frequency Division Multiple Access (OFDMA) and it brings clients almost multiple times more limit than its archetype, empowering a lot more gadgets to associate all the while, without any interference."

At last, Shikwambane says WiFi 6 offers a further developed reach and better force the board. "WiFi 6 is undeniably more sharp than WiFi 5. For instance, if an associated gadget is arranged some separation from the switch, Wi-Fi 6 has the knowledge to advise the switch to convey more grounded messages to those gadgets to guarantee they have satisfactory network.

"What's more, Wi-Fi 6 gadgets have a component called Target Wake Time, which empowers an AP to oversee movement across the WiFi organization, to limit medium conflict among stations, and to reduce the necessary measure of time that a STA in the force save mode should be alert. At the end of the day, this implies that battery-worked IOT gadgets need possibly converse with the switch when essential, which saves their battery life."
