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?
: 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.
: 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?
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.
