DJ and all, I think that the essential point that you
bring up is that an RS in this usage model can have an antenna mounted
externally for communication with the upstream RS or MMR-BS and an antenna
mounted internally for communication with downstream RSs and/or MSs. I think
that the detail about the two physical parts and the manner in which they
connect describes one way of building such a device and should not be part of
the usage model document. I’ve added an item to the agenda to
discuss this topic. Regards, Jerry Sydir From: Hi All: Yair and I would suggest to add the following
paragraphs at the end of the Section 3.2 In-Building Coverage Usage Model. " In some cases, it may not be possible or practical to place
RSs near windows facing the donor BS. Another approach would be to deploy a
split RS model. In the split RS model, the RS would be split into two
physical parts, one residing outdoors and the other indoors. The outdoor
unit (also called upstream unit) and the indoor unit (also called downstream
unit) connected through some physical cabling such as an Ethernet link over
CAT-5. The outdoor unit communicating with the BS is located on a roof or other
outdoor location while the indoor unit servicing the building is located
indoors. In a large building, it may be required to have a single
outdoor unit but multiple indoor units (e.g. one on each floor). In this case,
the “split RS” model will need to be extended to address the
configuration of a single upstream unit connected to multiple downstream units. " DJ Shyy |
