Change subject: bts-trx: Use TRXC cmd NOMTXPOWER to retrieve nominal tx power from osmo-trx ...................................................................... Patch Set 2: > Patch Set 2: > > The spec says: "The range over which the BSS shall be capable of reducing its > RF output power from its maximum level shall be nominally 30 dB, in 15 steps > of nominally 2 dB." > The power level field has 5 bits of which 4 may be used to set the level, one > is fixed to zero. > The b2xx series has a max rx gain of 76 dB and 89.8 dB max tx gain. > > So there is nothing to retrieve, the nominal power needs to configured in the > osmo-trx config for one specific device and frequency configuration that is > being used, an the relative power reduction always has to be relative to the > configured value. As discussed previously, the idea is that for now we hardcode a set of values per device type after doing some measurements. We can later on add VTY configs as needed. -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/18589 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: I682211f3d664c21f923ca4a530e0464ca383b6d9 Gerrit-Change-Number: 18589 Gerrit-PatchSet: 2 Gerrit-Owner: pespin <[email protected]> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: pespin <[email protected]> Gerrit-CC: Hoernchen <[email protected]> Gerrit-Comment-Date: Tue, 02 Jun 2020 11:19:28 +0000 Gerrit-HasComments: No Gerrit-Has-Labels: No Gerrit-MessageType: comment
