Q: My understanding of LTE is limited however, if the UE (CPE) is creating a 3gpp tunnel through the eNodeB back to the the cloud hosted EPC then my question is what addresses would my clients see on their home router?  

A: CPE can be configured to bridge or router mode. The address is assigned to CPE from cloud EPC.


Q: Which sector antenna you recommend?

A: One 2x2 sector per base station, preferably the 90 degree.  KP Performance can assist with these types of questions. CPE is an integrated 19.6 dBi panel antenna - (Band 42/43)


Q: Is the attention to CPE slotted or scheduled?

A:  Scheduled. LTE has about half the latency of WiMAX.  Operators who only have experience with WiFi-based or Cambium products, often ask about latency. There is no issue with latency with LTE, not even with gamers or other sensitive applications. LTE has about half the latency of WiMAX. The issue is really about jitter and that's problematic with best effort technologies like Wi-Fi because latency is so variable.


Q: Is there any way to lock a subscriber to a specific site ID?

A: To lock down to a specific site:

  • From the CPE web GUI, go to Network -> Scan Mode.
  • Click the Scan Mode dropdown and select PCI Lock.
  • Click Add List button.
  • Enter in values for EARFCN and PCI. Reference these values from the base station web GUI under Quick Settings.


Q: Can I link up to the CPE’s POE when using the Apple thunderbolt Ethernet adapter?

A: No, you can’t.


Q: How to enable CPE monitoring on the LTE gear?

A: To enable CPE monitoring on the LTE gear, log into the CPE and find TR069 under system settings. Enable TR069, enter the following fields and hits save:

ACS URL:  http://baiomc.cloudapp.net:48080/smallcell/AcsService

Periodic Inform Interval:  60


Q: Is there a way to bridge an alternate VLans to one CPE VS another?

A: We currently do not support bridging or routing to the CPE, but it is in the works as this is a high priority feature for us.


Q: Do I need a SIM card for the CPE?

A: Yes, you need a SIM card in the CPE before it will attach to the base station. There should have been a white envelope labeled SIMs inside the shipping box that CPEs were in.


Q: What is the max power that CPE allows?

A: 23 is the max value.


Q: What does the new power supply look like?

A: Like a standard 24V/0.5A POE with 3 prong C5 port.


Q: Does the CPE come with the POE adapter and power supply?

A: Yes, it does.


Q: Do the current CPEs support carrier aggregation to better use the new CBRS frequencies when they become available?

A: Our CPE is category 4 which does not support CA. However, the chipset that we are using could potentially be firmware upgraded to category 6, so there is a slight chance we may be able to support CA in the future.


Q: Can we control the speed of the end users?

A: Not yet. We should have this feature available in the feature.


Q: What does the red icon for CPE in OMC mean?

A: Red means not connected. LTE status is a parameter which is pulled from the CPE and keeps the value which was last updated.

Q: What setting do we need to use if we want to assign public IP via our Mikrotik Hotspot to limit bandwidth through VISP software?

A: There is no L2 option to be able to assign public IPs directly to the CPEs as this time. However, you are able to switch to router mode so that every CPE has its own private IP address. For bandwidth limiting, this is done through our Cloud BOSS server where you would configure your Internet packages and assign a package to each SIM card. Public access to Cloud BOSS is still closed, but we should be opening up access to it soon. We will also have an API developed and plan to integrate with VISP in the near future.


Q: Can operators add new CPE direct to OMC?

A: Yes, you can. You can add new CPE by MAC in system->device page.


Q: Is/should the iperf function in the CPE work? If so, is there a specific address/port/etc, or do we need to run our own server instance?

A: It works well, and we will release a guide soon.


Q: When we’re changing frequency/channel width/etc on the eNB are the CPE are the CPE’s supposed to automatically pick up and reflect that change?

A: The feature is on testing, and it will release in the future.


Q: Does the cloudapp OMC show a CPE’s current IP?

A: Yes, it does.


Q: Is there a recommended Ethernet surge suppressor with the Baicells UEs?

A: The CPE (EG7035) has internal Ethernet surge protector, but it doesn’t protect the indoor side (PoE adapter), also we can provide a external Ethernet surge suppressor.


Q: Will the UE firmware enable the operator to name the device with a customer name?

A: The eNB name can be changed by WEBGUi. Also, on the CPE side, we are planning to do this and will be release in the near future.


Q: Will the tuning lights be put on the side or top of future UE designs?

A: Yes, the new design will be release in a few months.


Q: What is a ghost UE? How does it happen?

A: A ghost UE happens when a CPE’s not release cleanly. It doesn’t harm anything and the ghost CPE session will eventually close on its own.  We covered it now with the new software upgraded.


Q: Is it possible to set the TR069 that make the CPEs to display in the cloud OMC remotely?

A: You would have to manually remotely log into the CPE to set this. It allows HTTPS over WAN isn’t enabled, then there is no way to enable TR-069 remotely.
