WiFi can use software to improve signal

To understand this problem, the following settings should be identified first:

1. "Improving WiFi Reception" refers to "receiving a stronger signal" or "getting Better network quality"

2. Soft definition, more soft and soft

3. A software that can reach a hard position

4. How reliable is a software

Too much nonsense or do not understand, you can directly look at 4

Say 1 First,

"Improving WiFi Reception" means "receiving a stronger signal" or "getting Better network quality"

If the former, then the software does not.

WiFi relies on electromagnetic waves, many of the same nature and visible light, imagine, the roof has a normal working light bulb, you can see the light bulb position, the middle of a fixed white paper as an obstacle, then you can see the intensity of light must be unchanged. The WiFi principle is similar.

But through the software to achieve "better network quality", involving the next issue, more soft and soft.

2. Soft definition, more soft and soft

Let's get to the conclusion.

By optimizing the link layer and the following, the theory can improve the quality of WiFi transmission, but many things in this layer are fixed dead and unchanging.

The software optimization of network layer and above can improve the network quality under any network.

If the device that sends the receiving signal is called hardware, the part that controls what kind of signal the hardware sends, is called the software, then the software can affect the network quality too.

Raise a chestnut, now in the WiFi network signal, there is a call guard Interval (GI) Things, simply said, I send two sets of signals between the time, to have a space between, so that the adjacent signal is not easy to interfere with each other, easy to accept, then this time interval can be longer, can also be shorter. I am very close to the route, with a shorter GI, a second can send more groups of signals, and away from the route very far, then use a longer GI, each signal can ensure accurate reception, network quality is better

Another chestnut, through optimizing frame structure, can achieve better network quality, The typical example is the comparison between 802.11g and 802.11n, can work on 2.4GHz, can use 20MHz bandwidth, the same condition n the upper throughput than G almost doubled, the key factor is more reasonable frame structure.

Only this kind of thing is hard to say is the software or hardware, and most of the rules are good, there is no room for change, such as for GI, hardware and drive together can automatically adjust to achieve the best results, such as frame structure this thing is completely stipulated dead.

and pure software, is the installation of the program, can optimize the network? can also.

Take a chestnut, Windows platform, there is a German software, Cfosspeed, by adjusting the priority of different network packets to achieve full load when there can be delays, through the adjustment Send Receive window, can make the transmission layer above the throughput rate a little bit, measured in some network conditions, have a certain effect, Genuine Lifetime 40RMB (other countries are sold about 300rmb+)

3. How hard can a software go

The operating system itself may be able to interfere with the lower part of the bottom, such as win, some network card drivers can be set to force short GI, and so on (although this kind of settings to keep the default effect should be the best ...) ）

For app, I didn't do web application development, also do not know what an app can touch what position, just so many years, I have seen do the most thorough is also under Windows CFOs series of products, some of the features take over the link layer of the content, the impression that these features already need to install driver.

and iOS and Android, an application is probably not touch the driver?

In particular, iOS, an app doesn't seem to affect another app's network activity?

4. Software unreliable

Or, I've seen the CFOs network optimization software is just one, I remember when I was in junior high school with Ben 3 or Ben 4, the software is doing, on the other hand, the software in most countries, the price of more than 300RMB, also shows that they are under the kung fu ... (Think about selling 40 in China, it's a lot of spelling ...) ）

Even if this effort, CFOs in some good network environment, also can not make much difference, because the existing network itself in response to the general application, already good enough.

And for random a so-called WiFi optimization software, I think the nature and xx battery assistant similar, make this software logic is "I know than Apple", "I understand than Qualcomm", "I know more than IEEE" series.

I guess there's a lot of these apps, like ads, or what other apps you're going to install, or what you're going to do to earn points? If so, then you can delete ...
