Anne Frank Funk posted:5g, here i come! do you go to mwca per chance? i'll probably go again this year anyways i think the actual big thing for "5g" is that connections should be much more reliable. the changes on the network side with femto cells everywhere and massive mimo will make it harder to overload networks. on the handset side carrier aggregation should make current bandwidth more reliable and allow better connections when in motion (hence the "5g ambulances" and "5g autonomous cars" things despite cars and ambulances being able to send telemetry since the 90s). the funny thing is that this is all still LTE, hence AT&T's marketing for their EPC/5GC setup hobbesmaster fucked around with this message at 02:27 on Mar 3, 2019 |

echinopsis posted:so not fundamentally different to lte, but we’ve improved things, and need a marketing term it turns out "long term evolution" was an accurate name! 5g-nr is the new bands stuff. theres also going to be unlicensed band stuff under the 5g umbrella (nr-u): https://www.qualcomm.com/news/onq/2018/12/13/3gpp-commits-5g-nr-unlicensed-spectrum-its-next-release

coke posted:current 5g status, no one loving knows 5g makes it easier to fire up your own private networks using unlicensed or leased licensed spectrum so it can kinda be a thing also yes you can just go out and buy some spectrum: https://selectspectrum.com/AvailableSpectrum.html

coke posted:who knew higher frequency band is garbage for coverage the trick 3gpp is pulling is that lte is a subset of 5G so you can call a 5G network back end that provides lte service 5g. i presume this is how AT&T is technically getting around calling LTE service 5G E.

Cybernetic Vermin posted:no idea why anyone would move on from such an awesome tech as 4g which works without antennas. the point here is that’s you have to use their 5g-nr antennas, not whatever you wanted to lay out

~Coxy posted:isn't mmWave going to be much more susceptible to antennagate style issues? thats why massive mimo is always said in the same breath along with the mmWave stuff still, seems like it'll help mainly with vehicles and fixed broadband and the like the company i work for does industrial mainly so 5g-nr is basically "uh no that won't work for basically any of our customers". catm/nb is really good in those kinds of environments (2g or better sensitivity) and should see a mass roll out along with 5g hobbesmaster fucked around with this message at 18:03 on Apr 21, 2019 |

if mmWave is good for anything it'll be fixed wireless finally giving cable companies some competition

I’m sure it’ll be fine, the carriers will be putting up microcells everywhere https://www.lightreading.com/mobile/5g/5g-and-millimeter-wave-band-challenges/a/d-id/735852 quote:Received power in dBm = Tx power + Tx antenna gain + Rx antenna gain – path loss – rain fade (est. 2dB/200m) - shadowing loss (20 to 30dB)– foliage loss (10 to 50dB) – atmosphere absorption – terrain /humility -– Fresnel blockage – system margin 10dB loss per kilometer. it’s fine! microcells will be as ubiquitous as power transformers!

as backhaul for all the femtocells in every street lamp or whatever is being promised today or as a home internet service. yes rain fade is a problem but if femtocells are everywhere it won’t be!!!!!

some towers already use fixed wireless for backhaul, its not like the carriers can't calculate rain fade for point to point installations like that consumer equipment on the other hand...

Perplx posted:I wonder how many 5g networks will be "Carrier-grade NAT" ipv4 only every pdp context on consumer networks in the US I’ve seen is ipv4v6 and are mostly using the ipv6 address already IOT networks and business networks with VPNs and such still seem to be ipv4 a lot of the time though

how about we just all agree on not using the huawei baseband because they're garbage compared to qualcomm i can't really comment on the nationality thing though because i tell people to buy italian cellular radios as part of my job.
