MIMO support from Pepwave cellular modems

Product Discussion Pepwave MAX
1

I have searched this website for a place where it is published that the Pepwave devices support MIMO technology for the cellular part of the modem. Specifically, I am looking at the Pepwave MAX Duo Pro Dual Modem. Yes - it has 4 cellular antenna inputs, which would suggest that it supports MIMO 4x4 (?), but - why is this not mentioned in the technical specs? Or, it if is, I can’t seem to find it. The only thing I can find is WIFI 2x2 Mimo support. Can somebody please post a link to a specifications page (published by Peplink) that shows the Pepwave Max Duo Pro supports MIMO for Cellular!!? . And - if it does - does it support MIMO 2x2, or will it support a 4x4 Mimo antenna? Thanks.

Short answer: All of the cellular modems used by Peplink are MIMO.

Longer answer: That’s because Peplink does it “one better.” Peplink fully specifies the category (“CAT”) of modem used in each device. That will lead you to the specifications associated with each category. (Peplink also does not discuss modulation scheme and other such information as that’s associated with the category of modem.) See, for example: LTE UE Category & Class Definitions - CableFree .

Recommendation: Pick a product which has the sort of modem you want vis-a-vis category and the bands you require. If you have a question check with a Peplink Partner – who can certainly help.

I have been working with several of your partners - and they could not answer my question. I think the technical literature should mention MIMO if indeed the Peplink products support MIMO. Why would you not do this? I already have narrowed things down to the MAX Duo Pro Dual with a Cat 7 and Cat 12 modem. It just seems strange (even suspicious) that the data sheets would not mention MIMO for the modems. They have no problem mentioning it for the wifi portion of the device.

Should Peplink also say the modems in their routers can employ Orthogonal Frequency Division Multiple Access technique (OFDMA)? Or, indicate when Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) is in use? I’ll leave that to your judgment. Meanwhile, as a Partner, I am perfectly happy with Peplink’s representations of the CAT of modem that is included and the bands on which it operates – and I believe that also has satisfied our customers and clients (knowing the difference in the terms.) But, I’m just a dumb engineer. ;<)

And, just so there is no misunderstanding, I am a Peplink Partner and PCE; I am not an employee of Peplink and cannot speak for the Company. (I mention this in response to your reference to “several of your partners.”) If you believe you require more information than the data sheets provide you may wish to submit a feature request and reference this thread.

Hello, gentlemen…
About MAX-TST-PRO-DUO-LTEA-D-T-PRM:

OK yes - this message is meant for Peplink, especially marketing. I have what I need now, but it would have been easier to just read it on a data sheet.

Thank you!
