Operation trade technology was in charge of active and outward bound to admit recently: The bandwidth of “ our acceptance and user use a network actually fast differ very far, it is common phenomenon. This is alleged false broadband. ”

The problem of false broadband caused the attention of the outside again. To domestic user, a very big doubt depends on, why net fast always follow conduct propaganda do not accord with? Actually this problem notchs wait for in light of two kinds of circumstances.

The first kind of circumstance: The definition is promiscuous.

If the user deals with the broadband that is 20M, the 20M here is to point to every second 20 million bit (namely 20Mbit/s) , and a few real time that the user uses measure what fast software shows normally is the speed when the user downloads, its unit of measurement is 1000 byte count every second, this is both it is 1:8relation, so of 20M broadband correspondence is the download speed of every second 2.5MB, the every second 1.25MB of 10M broadband correspondence, of 8M broadband correspondence is every second 1MB…… with this analogize. But these are theoretical rate, should compare this actually slightly some lower.

Still be with 20M broadband exemple, if if can achieve 2MB/s,download speed, can conclude basically net fast it is to accord with those who receive a standard. Global any country cannot be accomplished 100% offer theory to download speed. The United States, Japan, Korea such area technology is relatively banner, can achieve 90% the left and right sides, fluctuant inside the limits of 75%-90% , all can treat normal condition.

So, the conclusion of the first kind of circumstance is, if the user discovers his net fast with actual download 8-10 differs between speed times the left and right sides, do not complain first, was to forget to undertake conversion to the unit likely very.

The 2nd kind of circumstance: After the user undertakes unit conversion, net fast as before far apart, may be to encounter ” of “ false broadband really.

From the point of broadband network structure, the broadband rate that business of 3 big operation offers arrives among user terminal still have other receive facility, so effective rate and academic meeting have deviation, and what segment enters secondhand in control is business of 23 class operation.

Business of operation of 23 class network to seek taller economic increase, making sure broadband network user uses an experience is the main reason that poses problem of ” of “ false broadband. This basically causes by two reasons: One is to enjoy a broadband to change alone share, another is the designation with compulsive unqualified installation network.
