These are links (not all free) that may shed some light.
My background: IEEE Senior Member, only person to have IEEE WCP and all 4 CWNP certifications. IEEE Senior Member in following societies: Communications, Microwave Theory and Techniques, Computer, Power and Energy. IEEE Joint Signal Processing and Communications Chair - Hawaii Section
Keysight Technologies and a couple of other vendors had presentations on test equipment at the annual IEEE MTT symposium that was held simultaneously with RFID and ARFTG this past June.
I will monitor this forum and try to post relevant items/articles of interest.
Rather dated since 2015, but BLUF (bottom-line up-front): There is no common technical framework in which stakeholders are working, which makes it very difficult, if not impossible, to interpret research results across studies.
Could you comment in another conversation thread we have active in this forum? The subject of the thread is ACC - Advanced Cellular Coexistence. I would be very interested in your input on this feature. The only information I have seen is some meanless marketing babel.
I will take a look. Only discovered these Forums because I clicked on the wrong link. Was actually trying to take a look at the White Papers link.
Some more details:
From what I have read, it sounds like the LTE folks are hell bent on pushing their products without much in the way of real test requirements or test results analysis.
They are presenting test recommendations, but no pass/fail criteria. It's all up to the manufacturers and their customers on wether a device is a good product or not.
The FCC should really be doing something about this ahead of time.
Thanks for the reading material Howard.
Agreed, the FCC should show some leadership on this, but given the present political environment that seems unlikely. Unfortunately a lot of this problem is layer 8. Given some time an organization such as wlanassociation.org may make a difference. After the presentation at the last CWNP conference it seemed worth a try.
I just read in the Wireless Broadband Alliance (WBA) 2017/2018 Annual Industry report their view of the situation. It had two statements which surprised me.
"Though most regulators do not pronounce on individual technologies, they do get involved if there is risk of interference with existing services. This explains why the FCC has taken an active interest in the debate between the Wi-Fi and the 3GPP communities over LTE-Unlicensed (LTE-U)."
What ? Who says ?
"However, in most cases LTE-U is being superseded by LTE-LAA (Licensed Assisted Access), which does support LBT and runs in the 5 GHz band, provided it is anchored to a host network in licensed spectrum. Some operators, such as Verizon Wireless in the US, are embarking on commercial deployments of LTE-LAA."
I thought really only the EU was pushing the LAA route ?. I hadn't seen anything about our greedy phone companies wanting to do the same thing.
It sounds like the phone industry would like to kill the 2.4 GHz band (using 802.11ax) in addition to 5 GHz. This need to be snipped in the bud.
