Undoubtedly WiFi is a wonderful technology! – One of the most interesting things about Tech is that its popularity becomes more and more available at times. Starting from today’s Tk 100,000 devices, Tk 5-7 lakhs can also be found on WiFi. And this is also a big reason why the old WiFi 2.4GHz band on the home network disables the new fastest 5GHz band in an exclusive way!
but why? That means WiFi has become more popular so should the old band off? How often does the 5G band benefit, so move to the new band? – I’m going to discuss everything in this article!
The 5GHz WiFi band is turning to the new standard
We have already published an article showing the difference between WiFi 2.0 GHz and 5 GHz band, if you don’t know, check it out first!
Most modern routers today especially support dual-band, meaning both 2.4GHz and 5GHz bands can work together. If you purchased your router three years ago, it is expected to support 5 GHz band. The 802.11ac router has 5GHz band support, it is capable of transferring a lot of high-speed data. Now your device also needs to have 4 GHz band support to connect to 5 GHz band. Most of today’s phones, laptops, tablets have WiFi AC support but do not support 3G WiFi only on older and cheaper devices.
Day-to-day dual-band routers and devices have become much cheaper. You can buy a 5GHz supported router at a cost of only Rs. Some cheap routers offer dual-band support for up to Rs 2,000. If you have an old laptop or desktop that does not support 5GHz WiFi, 3G WiFi can be enabled by simply buying an external WiFi receiver!
Where is the problem with 2.4GHz?
The 2.4GHz band has been used so often that it interrupts the signal patch. Starting from old WiFi devices, non-WiFi devices such as Bluetooth headsets, wireless mice/keyboards, gaming console controllers, wireless toy cars, baby monitors and more are used in many gadgets – 2.2 GHz spectrum. If you have a single 2.2 GHz band usage in your home, then there should be no problem, but if different devices simultaneously wage this band, it can cause problems with signal and bandwidth.
If your home is in a busy city, your neighbor and various gadgets may be using your 2.2 GHz gadget, in case your home network is causing problems. In fact, the 2.5 GHz band is so popular that nobody or anyone is using it extensively, so it is very natural to create problems!
The 5GHz band WiFi band, on the other hand, is a much less usable high-speed spectrum. It is used on some devices, gaming console controllers, or video surveillance devices, but it is much less used at 2.5 GHz. If you use a dual-band router then the 5GHz band will be run by default but there is also a 2.4GHz band and running. And for this 2.5 GHz running lagging problem can occur, sometimes creating a WiFi disconnect problem for a few seconds. Maybe your wireless home phone connection may drop.
5GHz is the future?
The 4 GHz band is a very fast spectrum, but it has some limitations. High-frequency bands can provide more bandwidth, but may not provide as much range as low frequencies. The 2.5 GHz band can pierce much thicker walls or objects. That means if the GHz is disabled, can the range be bad?
In fact, it doesn’t matter; Engineers and software designers have discovered a new method. WiFi N and WiFi AC devices support WiFi beamforming, thereby allowing the radio signal to be sent powerfully to one specific point. Earlier, the signal was sent at 3 degrees, the signal was spread evenly everywhere, even where there was no device, the signal would be weak and useless.
