RTS 3.4.8 - New eNB software has been released!

RTS 3.4.8 for Nova R9 TDD base stations has been released. This version includes many bug fixes as well as adding important features like uplink 64 QAM, PRACH format 2, subframe config 0, 1588v2 sync, and jumbo frames. Starting with this version, we will also be changing the CloudCore PLMN to 314030.

SUPPORTED HARDWARE:
Nova 243 (2*10W eNB | BRU3501,3510,3511)
Nova 233 (2*1W eNB | mBS1100,1105,11002)
Nova 227 (2*250mW eNB | pBS2120,11004)

:warning: NOTICE: BEFORE UPGRADING THE ENB, you will want to check if any Baicells Cat6 (Atom OD06) CPEs are connected to the eNB. For every CAT6 CPE which is connected to the eNB, you will want to verify that roaming is set to enabled. If roaming is set to disabled on any CAT6 CPE, it will prevent them from attaching to the eNB after the upgrade if the SIM card used does not begin with “314030”. These CPEs also use the following model names: EG7010CM11, EG7010AM11, or EG2013BM11. You can find the model names listed in the OMC under CPE > Monitor. From the CPE webgui, you can find the roaming setting on the Settings > LTE > Internet Settings page.

:warning: NOTICE: BEFORE UPGRADING THE ENB, please check the firmware version, eNBs with “BaiStation_V100R001C00B100” or earlier versions will need to upgrade to “BaiStation_V100R001C00B110” prior upgrading to RTS 3.4.8

:warning: ADDITIONAL NOTICE: There is a known bug with the Atom OD06-L (EG7010CM11) CPE which prevents remote web access. This will be recovered by a future software upgrade. In the meantime, the only way to check the roaming parameter on this CPE model is from the LAN side.

:bulb: QUICK TIP: In regards to the PRACH format 2 feature, here are some things to note:

  1. Subframe assignment (SA) will need to be set to 1 or 0. This is because the PRACH sequence (1.6ms) length will be greater than the length of one subframe (1ms). This means at least two UL subframes are needed.

  2. Zero Correlation Zone Config (ZCZC) may need to be changed based on desired cell radius. You can reference the chart below for appropriate setting:

  3. Special Subframe Patterns (SSF) will need to be set to 5 if target cell radius is over 15km.

  4. PRACH Configuration Index will need to be manually adjusted and the help text will change the range to 30~39. For fixed wireless, it is suggested to set this to 30, 31, or 32 (allocates the lowest amount of random access resources). You can find the PRACH configuration index table for reference below:

So how do I download a config in XML format?

Note: Customers need to set/make sure CloudEPC is enabled before upgrading, save and then upgrade to 3.4.8. No need to reboot after setting the CloudEPC, hence the upgrading will also reboot the eNB. This is a very important step.

Did my upgrades several days ago. Did not check that setting. Where do I find it? Must be getting old.

Cloud EPC switch is on the Quick Settings page.

What about us without cloud core? Can we update at all then??
