Observers believe the Chinese are hard at work developing a homegrown advanced standard, known as TD-SCDMA (time divisionsynchronous cdma), and that 3G licenses will appear once TD-SCDMA is ready.
Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.
