Hitting a barrier?

I'd love to hear from anyone else in wireless backhaul that has hit this barrier.

At Silicon Image, we fully concur with Mark's observations. In addition to reducing equipment costs, phased array antennas reduce installation and maintenance costs, as the beam can be electronically steered during and after installation without manual intervention. The small size of phased array antennas, combined with the high performance, high integration and low power of CMOS 60GHz RF transceivers also enable wireless mesh networks - the best way to meet the capacity expectations for next generation mobile networks without digging up every street for fiber.

Keep tx power low

High tx power = higher power consumption?

 If you keep the tx power low and the antenna gain high. You will get lower power consumption. Thus, extended reliability and cheaper electronics circuits.

FCC / EU comparison (FS backhauling only)

I respect the view of silicon vendors (they better wish to have a single design for all application in the same band).

However, we should not forget that while FCC Part 15 regulation is for "generic radios" (i.e. with no specific spectrum access rights), EC/CEPT regulation is specific for Fixed links systems (having "primary" allocation in the band).

Therefore, while FCC rules are not specifically aimed to maximise the spectrum use for the users, CEPT coexistence study (ECC/REPORTs 113 and 114) are focussed on specific applications and resulted in a balanced regulation maximising (statistically) the availability for both "primary" and "other"users. In particular also for FS users among themselves; it should not be forgotten that EU urban backhauling links will be very short and the O2 absorption becomes of little help in managing interference when high density, multioperator networks are considered.
Furthermore, CEPT regulation in most cases are relatively easy to be changed when specific new technology is emerging and its fair compatibility with other users is technically demonstrated.

Anyhow, while the comparison in term of maximum emission limits shows large difference (about 30 dB), the comparison in the practical range of fixed links backhauling technology is significant less important (about 10 dB) and equipment manufactures feeling is that only few more dB power (in the order of 5) would eventually be welcome (possible discussion about ATPC enhance emission might be possible.
