Sure. The LTE technology that is being developed worldwide is an open protocol, an international standard. It's being developed by the third-generation partnership project called 3GPP. There are at least seven companies developing this technology to an open standard. That's the first thing I'd like to say.
The second thing is that the modulation scheme that's being used allows a lot of information to be transmitted over relatively narrow bandwidths of spectrum. If you can stuff more information into a particular segment of spectrum, then you get a lot of spectral efficiency. As people are using their iPhones and different devices that are consuming considerable bandwidth, having a very efficient modulation scheme is very important and is commercially attractive to operators, because they can sell that value into the marketplace.
