Re: Femto - IuH

Hi Harald, SCF has a similar thing for 3G femtos, but its pretty much the same L1 implementation and not talking about the management of the femtos. I actually looking into these units: http://www.ebay.com/itm/AT-T-3G-MicroCell-signal-booster-DPH151-AT/16185813… There is a lot of them, they are fairly cheap, I already know they run embedded linux (95% that its not VxWorks), and it is a Cisco product. If you or nobody has any opposition (know something that makes this unit a near impossible candidate), I will probably buy one and take a look. It seems the successor of this product is also embedded linux, and it seems AT&T deploys them in huge quantities, so this seems to be a good candidate.

This is _very_ far from the Iuh interface. Compare it with the L1SAP interface of OsmoBTS. And Iuh is on th level of the A interface, not even Abis. Also, this API is for LTE, not for UMTS. You can find transceiver hardware + PHY implementations that offer this L1 API. However, that is not a complete (femto/small) cell, but the hardware plus the PHY. I don't think anyone will quickly come about and implement all the missing layers, so in the context of developing a NITB with Iuh interface, it doesn't really help. I haven't really looked at any femtocells for a very long time. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
