Hi Sylvain, I asked a colleague of mine about nanoBTS model-numbers, he gave me a list of available models that he got from IpAccess when he was looking to buy some BTSs from them a while ago. They seem to use different internal and external model-numbers for the non-EDGE oval models, maybe not for the EDGE models; I've put in the three external->internal number correspondences I know for definite:
Model no. IpAccess ref. Description 108B 1800MHz single-TRX BTS GPRS - OLD 108D 1800MHz multi-TRX nanoBTS 139U 108DU 1800MHz multi-TRX nanoBTS 108E 1900MHz multi-TRX nanoBTS 108EF 1900MHz multi-TRX nanoBTS 108ER012 1900MHz multi-TRX nanoBTS 178U 108GU 900MHz BTS RoHS-compliant 108H 850MHz BTS - pre-release product 108HU 850MHz BTS - pre-release product
165AU 165AU 1800MHz EDGE BTS 165B 1900MHz EDGE BTS 165BU 1900MHz EDGE BTS 165CU 900MHz EDGE BTS 165DU 850MHz EDGE BTS 165 E012 1800MHz extended temperature EDGE BTS Pre Custom 165FM 1900MHz temperature-hardened EDGE BTS module
I know there are also models 110A and 140, both 1900MHz oval models, but don't know what internal refs they correspond to.
HTH, Mike H
Hi Mike,
yes, this is really nice thanks ! I'll put that on the wiki.
I didn't even knew the one I had was multi-TRX. OpenBSC doesn't handle that for nanoBTS I think (or does it ?)

"multi-TRX" in this context simply means that you can stack multiple unit to behave like one BTS with multiple TRX rather than multiple BTS with one TRX each.
We don't have explicit support for it in OpenBSC so far, but I think there should be nothing major missing either, as we already support multiple TRX in the E1 case. All we have is suddenly two TCP connections with RSL rather than one.
It probably boils down to somebody testing it and tracing any remaining bug, but there's no fundamental part of the code that needs massive changes to support this.
I'm in the process of building one of those custom modified RJ69 cables that you need to stack them. I'm busy with lots of other work, and it is not of very high importance, though.
Regards, Harald
