Alcatel-Lucent saves the mobile industry?

Today Alcatel-Lucent announced lightRadio™, “a breakthrough in mobile and broadband infrastructure that streamlines and radically simplifies mobile networks”. The solution was unveiled at a major press launch event in London supported by partners Freescale and HP.

According to, Alcatel-Lucent, the new lightRadio system “will dramatically reduce technical complexity and contain power consumption and other operating costs in the face of sharp traffic growth”.

The “lightRadio” represents a “new architecture” where the base station, is broken into its components elements and then distributed into both the antenna and throughout a cloud-like network. Suposedly, “today’s clutter of antennas serving 2G, 3G, and LTE systems are combined and shrunk into a single powerful, Bell Labs-pioneered multi frequency, multi standard Wideband Active Array Antenna that can be mounted on poles, sides of buildings or anywhere else there is power and a broadband connection”.

There is a saying: “if it sounds too good to be true – it probably is”….

Long ago I came to the conclusion that when it comes to active antennas it is not the active amplyfication that is the main problem – it is the filtering issue! Out-of-band emission requirements do not become looser just because the antenna that emits the signal has inbuilt active electronics. In order to meet out-of band emission requirements we today use caity filters. They are not that easily integrated into a “300 g cube”!
