Does anyone have details about the "advanced CPRI compression" mentioned in the press release? My company (Samplify Systems) has been doing similar processing for years.

LightRadio will actually change the way base stations look. Currently the defacto design for base stations is to have antennas on poles, connected with waveguides to the radio subsystem (which is happens to be as big as refrigerators). LightRadio leverages the advanced chip technology such that much of the radio functionality is miniaturized and included in the antenna chassis.

I don't think it is. This has been discussed at antenna-theory.com: http://www.antenna-theory.com/phpbb2/viewtopic.php?t=143 The idea of adaptive antennas (or smart antennas) has been around for quite a while. Arraycomm already does it. I'm highly skeptical they will be able to properly track users to enable the proper spatial diversity gains.

Does anyone buy this claim? Ben Verwaayen, CEO of Alcatel-Lucent, said: “lightRadio will signal the end of the basestation and the cell tower as we know it today.” Is lightRadio impressive or not?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
