The choice of no line from the use of mistaken ideas high transmission distance

The development of wireless technology to promote wireless products to the home users, by building a wireless network within the home, can let us anytime and anywhere through the installation of wireless network card notebook and desktop to enjoy the joy of wireless surfing. But for most of us, often in the use of wireless products on the existence of more or less misunderstanding, today we will introduce readers to the error of transmission distance, hope that through this article can help readers do not let convenience become troublesome, effectively avoid the use of these wireless routers misunderstanding.

Blind pursuit of high transmission distance:

Many users are ready to buy wireless products, for fear that wireless signals can not cover every corner of the room, afraid of their own wireless network eventually become a mixed network, in some places have to use network cable to connect. In this way, the purchase and selection of wireless products to the product logo on the transmission distance too much of the fancy. As long as there is a transmission distance of 500 meters is absolutely not to buy 200 meters.

1, transmission distance of the misunderstanding

In fact, this is also the user in the choice of wireless products on another misunderstanding, the first thing we should know is that the manufacturer said the transmission distance is in the absence of any obstacles to the measurement.

In addition, the manufacturer's marked transmission distance is the radius of the transmission range, in other words, 500 meters means that when I put the wireless device in the center, around him and back and forth, in all directions from the distance of 500 meters can have wireless signal, that is, his coverage is a sphere, and the mark is the radius of the sphere.

In addition to the actual use of our family because there are many walls, including load-bearing walls and ordinary walls, wireless signal transmission is straight line, will not turn, so the only way to cross these walls is horizontal crossing. This will cause the wireless signal attenuation, penetrating the load-bearing wall and more than through the ordinary wall signal attenuation. This is why the transmission distance and intensity of the wireless signal is quite different from what the manufacturer claims when it is used by ordinary users.

2, new technology to improve transmission distance misunderstanding

In addition to the transmission distance claimed by the manufacturer, many users also value the so-called new technology, which is the same as the value of new technology 108M products mentioned above. May be in our choice of products JS will introduce you to this product how good, using what kind of technology, thus greatly improve the transmission speed and transmission distance.

In fact, we should keep in mind that no matter what technology and function, in the current wireless signal based on the premise of 802.11G standards, through the introduction of new technologies and features to achieve the speed and distance of the big upgrade is not realistic.

3, according to the need to select products

If you really have high transmission distance requirements, then the author suggested that users must look at the selection, it is best to buy more in the Internet to look at the product evaluation article. According to the author of nearly 10 different brands of wireless equipment experience, the gap in the product is also relatively large, and some 108M products are inferior to the quality of 54M products, we must remember to buy more.

Therefore, it is necessary to choose which products to be based on the actual situation of their own family, if the general product can cover the whole house, there is no need to spend more money to buy 108M products, after all, enough can be.

In general, we are in the study of wireless product transmission distance also do not be blinded by product parameters, some bad manufacturers even use false parameters to confuse us, we do not rely too much on the so-called new technology, before buying a good market research, choose the right product is the key.

Summary

The author of this article introduced to you in the selection of wireless products there is a misunderstanding of the transmission distance. I believe it can help you to choose the products for your readers.
