OK, that makes more sense. What I have heard described previously was a range of a few meters. It sounds like it is not going to show up on mountaintop-to-mountaintop applications, but more so in femtocell interconnectivity.
How is the penetration? How does it compare to wifi at penetrating structures, walls, etc?
Oxygen absorption restricts practical range to ~1km for low cost backhaul applications, but when dealing with smallcells (designed to improve coverage for 4G networks), and combined with the directional nature of the technology, this is in fact an advantage as it allows freq re-use.
Even in the 'mature' .11bgn/ac space a number of System IP companies are helping other fabless/ODM will access to WiFi technology. We also see this model applying to the .11ad market - and the baseband's design constraints are very different.
Hence we are in no rush to be acquired - although if someone were to offer $1B I would find it difficult to refuse!
Well Henry or somone else at BWT would probably be best placed to describe this.
BUT my understanding is that 4G tends to get deployed as a large number of small cells at somewhere like an airport and you need to aggregate all the traffic through the small cell basestations and send it up/down the line.
60-GHz carrier using similar but not necessariy identical comminications protocols to WiFi is being used to do this. Because the cells are small and close packd the distances are not enormous.
I have been following the evolution of 60 GHz technology and I am glad to see it close to escaping from the labs, but I am a little confused by the description of it as a backhaul technology. Most of what I have seen described as far as applications has been very short range and in the consumer space. How is this applicable to cellular or other backhaul?
