Hello,
I would like to run my EM9293 on 5G band n46. I know that other vendors, like Cisco, have built modules that could operate on this frequency using EM9293. See P-5GS6-R16-SA on this page:
5G n46 is not supported according to specification
Thank you for your no-help so far, always appreciated!
I am looking for input from people on this website who have a more positive and helpful attitude than yours, hopefully, they do exist.
FYI, as I pointed out in my post, EM9293 does support the band for two reasons:
1- It is based on Qualcomm XF85 modem which supports this band.
2- As I already mentioned in my earlier post, Cisco have a product that operates on this band which is based on EM9293.
Not quite get your point…
Do you mean the specification is wrong???
Indeed, you don’t.
A specification tells you what the module offers right now, but it does not tell you what the module could do. This is not the first time it happened with hardware where the spec under reports what the hardware could do. Yes, EM9293 could support more frequencies as there is no hardware limitations that stops it from supporting this band. It’s clearly something to do with the software.
I speak to hardware vendors all the time, and yes, they choose to close a specific functionality sometime despite the fact that the hardware could deliver it.
Here says it is not using the qualcomm chipset you mentioned above:
Good luck!
LOL, you want to tell me that you speak on behalf of Sierra Wireless yet you don’t know which processor their product is based on to the point where you had to bring in an external link?!
FYI, I made a mistake: EM9291/9293 is based on Snapdragon X65 5G which does support Release 16 and N46: Snapdragon X65 5G Modem-RF System | Qualcomm…-,Qualcomm%C2%AE%20Snapdragon%E2%84%A2%20X65%205G%20Modem%2DRF%20System%20is,private%20networks%20via%20software%20upgrades.&text=more-,Qualcomm%C2%AE%20Snapdragon%E2%84%A2%20X65%205G%20Modem%2DRF%20System%20is,Signal%20Boost%20and%20Qual…&text=Qualcomm%20Snapdragon%2C%20Qualcomm%205G%20PowerSave,and/or%20its%20subsidiaries.
And if we are going to use web links as evidence, I believe I already provided a link that points to a Cisco product based on EM9293 which supports this band. BTW, I even spoke to one of Cisco’s engineers and he confirmed it.
Finally, may I ask that you to refrain from replying to my posts if you don’t have anything productive to add. You are clearly not as knowledgeable about EM9293 (and maybe other Sierra Wireless products) as you might think, and I appreciate it if you could leave roam to others who might look at this topic from a different angle than yours.
Thanks.
I post the external link is to show you:
- you got the wrong information
- you can do some research in google to get the correct information
OK, no problem, from now on, I will not reply or give idea to any of your questions anymore
Not sure what ideas you gave me, but thank you, much appreciated!
I have some experience with bands and band support. We had a project where Sierra Wireless tech support taught me a few things. First, check the module product technical specification. They call it the PTS. I just checked that pdf. On page 11, in table 1-2, 5G NR band n46 is not supported. Just LTE band 46 is supported. Maybe the Cisco spec is wrong? I do not know.
Thanks! I guess we come from different backgrounds and have different experiences. I do check the spec of any product I purchase and use. However, I know that specs don’t tell the full story, i.e. the engineers who write them tell you what you could do with the product but don’t tell you what the product could do.
Vendors often close a specific functionality for whatever reason. I was speaking to an Eriksson engineer the other day about a similar product where he confirmed that they closed access to band n46 despite the fact it is supported. Their product is based on the same Qualcomm 5G modem on which EM929x are built. I also wrote another post where I asked the same question in which I mentioned that I spoke to a Cisco engineer who confirmed that their product supports this band.
BTW, by questioning the reliability of the Cisco spec you are somewhat contradicting yourself: on one hand you say that we should trust specs then on the other you question Cisco product spec!
I understand. Bands and bands support can be confusing. I trust the Semtech, Sierra Wireless spec. I know you are going to ask why? Because the Semtech, Wireless RF Engineering staff comb the PTS for completeness and accuracy.
I reviewed the Cisco specification that you refer to. I see the information in reference to P-5G-R16-SA. My view is - Cisco made a mistake in reporting n46 support.
I think you misunderstand the meaning of a specification document. As I mentioned, I spoke to the Cisco engineer, it’s not a mistake in the spec.
I see. So then what do you think the problem is? Based on your responses here, I am guessing you think the problem is with the Semtech, Sierra Wireless spec. Semtech has it wrong and Cisco has it right.
New question - when you talked to that Cisco engineer, did you mention the Semtech spec and the difference in the spec pdfs?
If not, that is what I suggest. That is what I would do. The official response from Semtech is here, from jyijyi.
New question - where did buy the EM9293 module? Asking because support can be received from that company, that distributor. That is how I receive support. This forum is helpful and supplements support from our distributors.
