ATC we have set up, but the actual testing process, we are to simulate a variety of network environment, the network environment of China Mobile, Chinese unicom and telecom, each operator and 2G/3G/4G and other different network 2G network
The domestic 2G network is called Edge Network, the theoretical peak value for me from the comparison with GPRS, EDGE speed how the rate range in this article is 384-473kbps, which is generally the downstream rate. Then we need to set up in the ATC when the uplink and downlink, then how to get the upstream rate, but also according to the above article to the edge of the downlink rate of 2.5 times times the upstream rate. So I configured 2G network for (temporarily not configured packet loss rate, delay what): down:400kbps up:160kbps
After the configuration is complete, let's say what the uplink and downlink of the network mean. Uplink is the speed of upload, the downlink represents the speed of download. However, Kbps is not equivalent to the kb/s we know, such as the 400kbps downlink rate above indicates that the maximum download speed should be 400/8 = 50kb/s, presumably this way. 3G
China Telecom uses CDMA2000, the Chinese mobile uses TD-SCDMA, and Unicom uses WCDMA, the above article is written as follows:
So I set up a 3G network based on the corresponding relationship:
