By efficiently handling call silence, China Mobile has doubled the capacity of their base transceiver stations in Inner Mongolia with a handy little device called the Vmux-400. “So what?” you ask? Well, costs didn’t go up as a result of the upgrade. Doubling your efficiency at no effective cost is no mean feat. On top of providing better service to remote villages, the hardware also acts as a solid stepping-stone to 3G advances down the line.
“The Vmux-400 also provides a valuable head start for mobile operators in their migration to 3G, since optimization enables operators to free up leased lines used for 2G/2.5G traffic and apply them to their 3G networks,” [Thomas Q. Lu, President of RAD China] explains. “In this way, they can avoid the time delay and costs associated with installing additional leased lines,” he adds.
