Q: If I want to change the bandwidth from 20 Mhz to 10 Mhz, I see where to do that on the eNB. Is there a setting on the UE that needs to be changed as well or will it auto-detect and adjust accordingly?
A: No. It is automatic; however, it's recommended that you reboot the eNB.


Q: Is the base station powered by POE?
A: The base station is powered by 48V DC. A power supply is included. The power cable is not included.
Q: Does the base station support fiber?
A: Not in the current model, but future models will include an SFP module option.
Q: Do you have a management port?
A: Yes, one dedicated Ethernet port.
Q: How many users are supported?
A: 32 active and 96 connected. 64 active will be supported with future software upgrade. It is recommended to not use more than 50 connected users.
Q: What is the typical latency?
A: 10ms with 2 subscribers. Typical is 20 ms. Jitter is 1 to 2 ms.
Q: What are the maximum download and upload speeds?
A: Depends on TDD SubFrame Assignment configuration. Defaults are 110 DL and 20 UL.
Q: What is the maximum distance?
A: In the LTE standard under the most common TDD settings, max modulation in a LOS scenario should be achieved at 30 km (18.6 miles).
Q: How does the Baicells Nova R9 solution compare to alternative LTE solutions?
A: Our solution is designed to reach the majority of the market with disruptive pricing, plug and play simplicity and optimal performance.
Q: Is GPS included?
A: Yes, GPS is built into the Nova R9. A GPS antenna will need to be added.
Q: How many base stations can sync together?
A: Base station syncing is unlimited.
Q: Does the Nova R9 base station sync with other LTE manufacturers equipment?
A: Baicells follows the LTE 3GPPP standards and sync with many other brands.
Q: Does the base station have a built-in spectrum analyzer?
A: Not at this time. There is an extra N-Type connector on the Nova R9 planned for spectrum analyzer functionality in the future.
Q: What antennas do you support?
A: Any 2x2 dual slant 3 GHz sector or omnidirectional antenna, which is cross polarized will work. We will provide a list of recommended antennas soon.
Q: Will the base station support the upper 25 MHz for FCC part 90 rules?
A: Yes. By separating the Data Plane and the Control Plane, Baicells can conquer the low latency issue with a IPSEC tunnel to the Cloud EPC.
Q: What is the operating temp range? Can it support operations in –40C weather?
A: Current specs for the Nova R9 are:
     Working temperature: -35C to 55C
     Storage temperature: -40C to 70C.
Q: What is the length of the Baicells manufacturer warranty?
A: 1 year starting after purchase from authorized distributor.
Q: What does the OAM interface look like?
A: The Nova R9 detects and accesses the cloud-based EPC & OAM automatically. Give the unit an Internet connection and it is essentially plug & play. The OAM is a web based GUI.
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: Will there be an option for Layer 2 connections?
A: Currently in testing. Layer 2 is projected to be supported soon.
Q: Where am I setting bandwidth restrictions and how is it controlled?
A: OAM console.
Q: Will I have GUI access to the UE if I'm not directly plugged into it?
A: UE GUI access is projected to be supported soon.
Q: Are the UEs SIM card based?
A: Yes
Q: When my equipment arrives what kind of information should I expect to arrive with it?
A: User manual will be provided.
Q: Do you have a proposed channel plan. antenna down-tilt, antenna polarization, or antenna separation?
A: ABAB (reuse 2). Down-tilt depends on desired coverage. Dual slant polarization.
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: Can one side of the base station be painted?
A:  You could paint the front part (which was a plastic cover) because the back was built to dissipate heat and could not be painted or it could over heat the base station.
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: What is the proper way to set the mobile carrier code on the EnodeB because none of WISPA are registered with the GSMA?
A: All operators using our cloud EPC share the same PLMN which is 31198.
Q: What the aggregate capacity/throughput on the LTE AP is?
A: Total aggregate throughput of the LTE base station is 112 Mbps DL in default configuration.
Q: What is the proper way to connect the power module to the cable that going up the tower?
A: You could use wire nuts.
Q: Do you have a built in 3.65 Ghz spectrum analyzer in the system, or Do we need to buy a standalone one? If so, any recommendations?
A: We do not have a built-in software spectrum analyzer yet, but it is a priority of ours. In the meantime, you could use a standalone spectrum analyzer or use CPE metrics to determine best channel. One of the engineers recommended a handheld Agilent spectrum analyzer.
Q: What are the recommended setting for the BTS such as Cell ID, MME IP, PLMN, and TAC? What do they do?
A: Cell ID, MME IP, PLMN, and TAC are all settings required for the cloud EPC and should be left untouched.
Q: Are there any PIM concerns with mounting the eNBs on the same standoff behind the antenna?
A: No, we have had other trial operations install their eNBs in similar fashion with success. Our eNBs are shielded fairly well.

Q: Can your equipment co-exist with WiMax gear or other wireless equipment?
A: Yes, our equipment can co-exist with other wireless equipment as long as there is not frequency overlap and there should also be antenna and radio separation from the existing equipment as well. Also, the further the channel separation the better.
Q: How to install the GPS surge?
A: The only way to install the GPS protector is backwards (at the GPS antenna), and we use smaller arrestors which is a short N-type jumper cable that will be included.
Q: Logging into the Base Station device will open the main page, but selecting any of the items in the left column takes you back to the login page. Can’t get any further.
A: It is due to having more than one tab open to the base station web GUI. You can resolve this by either closing the second tab, closing and reopening the web browser, or accessing the web GUI from a different web browser.
Q: How does traffic shaping work?
A: Traffic shaping will require two steps which are:
  • Upgrade of eNB software. The next software update will support UE_AMBR (traffic shaping).
  • Access to Cloud BOSS server. Configuration of DL and UL data rates will be done through BOSS.


Q: On the power connector, it is labelled “a “and “b” not “+” and “-“, so which is which?
A: A is positive and B is negative.
Q: When assembling the power connector for the base station does it matter if the red (positive) wire goes in the A or B hole in the connector?
A: Yes, it does. “A” is positive (+48V) and “B” is negative.

Q: What is the power consumption of the base station?
A: <65W.
Q: Should storms going through cause connections to drop?
A: No, storms should not impact a properly installed linked of any brand or protocol because all should be planned with appropriate link budgets. Also, for a link to completely drop, you may have another issue like a water problem.
Q: Can I change the name in the eNB?
A: Yes, you can.
Q: Do I need to reboot the base bastion after changing channels?
A: Yes, you do need to reboot the base station if making any changes under quick setting (includes frequency and channel bandwidth changes).
Q: Why would eNodeB reboot for no reason?
A: eNodeb reboot should have reason, we can check the reason according to the log.
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: If the frequency of the eNB is set at which is currently 3660/20MHz. So does this mean that 3650 to 2670 will be taken up by the eNB?
A: Yes, if the frequency 3660 is set, it means 3650~3670 is taken up.
