ATC we have set up, but the actual test process, we are to simulate a variety of network environment, the network environment is divided into China Mobile, Unicom and Chinese telecom, each operator is divided into 2g/3g/4g and other network 2G network
Domestic 2G network known as Edge network, theoretical peak for me from the comparison with GPRS edge speed how this article in the rate range of 384-473kbps, this is generally the downward rate. Then we set up in the ATC when the need to set up and down, then how to get the uplink rate, is also based on the above article to reach the edge of the downlink rate of 2.5 times times the uplink rate. So I configure 2G network for (temporarily do not configure the 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. But kbps is not the same as the kb/s we know, for example, the 400kbps downlink rate above us means that the maximum download speed should be 400/8 = 50kb/s, probably this way. 3G
China Telecom is using CDMA2000, Mobile is using TD-SCDMA, the Chinese unicom is using WCDMA, the above article written standards as follows:
So I set the 3G network according to the corresponding relationship:
