<10,000 teenagers arriving at rock-festival> Sort of like this? Just rolls over and dies? Mobile phone system returns normal in Beijing Jul 13 2001 2:16PM Homeway The Global System for Mobiles (GSM) network in the Chinese capital resumed normal operations early Thursday morning after emergency repair by technicians with the city's mobile communication company and the network supplier Nokia Corporation, Xinhua reports. According to the Beijing Morning Post, some of the GSM users were unable to make or receive calls Wednesday when an unexplained glitch in the network prevented signals from connecting. Sources from the China Mobile Communication Corporation (CMCC) attributed the trouble to the increase of new GSM users after the recent cancellation of the network registration charge, as well as the influx of tourists with mobile phones to the city who occupy a sizable chunk of the GSM network.

<WCDMA is designed for 5MHz (as GSM already is 200kHz)> Yes. But the original design had to be abandoned when WCDMA could not meet the (guard band) requirements of the FCC. Part of WCDMA ripped out by the roots (one sixteenth to be exact) and the remaining part is not so good to work with? Design not too good to start with or to end with? <QCDMA is designed for 1MHz (as AMPS-TDMA were 30kHz> I thought that Nokia decided that QCDMA is required for WCDMA, did I miss something? BTW, what does this mean? "[Conclusion] The adjacent cell test results show that the system performance cancel an order of magnitude when the adjacent cell interference power is 0-6 dB more than the transmission power of the base station. When the difference is more than 6 dB, the system performance declines more. During the real test, a majority of BERs are caused by paroxysmal interference. That is, there are many BERs during a certain time. This is because the system doesn't apply interleaving technology. Therefore, the test result that the system has middle-level power shows the worse system performance than interference power with more 3 dB. However, the order of magnitude is similar, which can be accepted. When interference power is more 6 dB, the test is carried out two times and the test results are different. This is also caused by paroxysmal interference. From this test item, it can be seen that the system uses different LA code to effectively resist adjacent cell interference. Thus, it can be proved that LA code can work normally" This designed by the number one CDMA guy. Does not sound very good to me.
