They were doing the polarization angular twist thing that will give you lots of channels per carrier but the antennas are weird, huge and fussy. And you have to have a different weird huge antenna for each chain.

The only path to improvement I see is really big beam forming array with even more MU-MIMO chains. Cost will go up accordingly I think. The alternate path would be millimeter wave with all the obvious caveats. Not trying to be a doomsayer, but I'm seeing a wall in front of me.

Maybe 6ghz being opened up will allow for using much wider channels, and keep things interesting, but I don't see things like MU-MIMO being more than an incremental improvement, like practically everything over the past decade or so. 60ghz has the potential to be a true competitor to fiber, but that's going to require a completely different network design than what we're used to.

I think RF Design hasn’t evolved much. Simple N=1 reuse and cell splits are the method that’s been used successfully for decades. Going smaller isn’t innovative. MiMo is a big leap however. Broader channels are the only way to deliver huge bandwidth. Going higher and higher QAM doesn’t work well for mobile handsets and the diminishing returns and crazy timing necessary to maintain a high QAM other than a lab are not practical. Small cells are UGLY. They’re also close to the people and EMR is a concern to many. The FCC has guidelines that I do trust but we’re not dealing with sites that are 100’ tall and every 1/2 mile now. They’re on just about every street corner. Most carriers are digging up the streets to bring fiber to each of these poles. It’s an expensive deployment. 802.11ax is the best innovation I’ve seen and it is truly 5G more than anything else that’s out there. 8x8 and 12x12 MiMo and color coded streams for interference mitigation are a big difference maker.

There's a compound annual growth in demand, and trying to think about how manufacturers will meet that going forward. I'm assuming we can't count on bigger channels or more spectrum. So what then? More MU-MIMO chains? Or is it going to have to be street level small cells (60ghz etc)? Or something else? We're investing heavily in fiber, as I know a lot of you are, but the wireless customers aren't going to go away. -- AF mailing list [email protected] https://urldefense.proofpoint.com/v2/url?u=http-3A__af.afmug.com_mailman_listinfo_af-5Faf.afmug.com&d=DwIGaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=oZldojrM2-7OE-SOcQyzFlyOFVuvqI9-MKCJpgPtw5o&m=bOiKRwWQBPYARG4WBm8Fvsompi82WCazDT9jImYirBk&s=y0OEvTCKA-uC0trV_bZmS0o2H7KqtGiFk0J4YCzSDSA&e= -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
