Spectrum Auction 2021

@Tejas01 intra band ca is almost on every mi ,poco ,and realm phones in the 20k range, interband ca is rare and have only limited support

Intra band is as good as useless. Better to invest in some worthy inter-band ca-supported phone to get some decent speed.
Rarely use it indoors.. for outside use it's ok to get the job done.

Anyone has any idea why my phone always prefers B40, which sucks because I am in that zone where B40 cannot work due to signal degradation but my phone loves to latch and lock to it in clear weather conditions. As soon as it rains, B40 degrades so much that my phone automatically jumps to B3 and the Internet is working well. I have Jio behaving like this btw. I use another phone, which doesn’t support B40 and Jio works flawlessly. So my theory is Jio should really signal phones better to switch away from B40 at less than optimal signal quality. B40 is feasible only for the ones closest to the tower.

My grandfather had got a phone which was for the US market only it supported only band 5. Since jio only has band 5 he has to continue using jio but the speeds around 20 mbps both upload and download.
The phone was Huawei Mate SE.

I have experienced the same but with Airtel. Latches to B40 which gives crappy speeds. But occassionally, it latches to B3(1800Mhz) and I get decent speeds. Seems like most cheap Intra-CA phones are designed to work in this manner as majority users are Jio and Max spectrum for Jio is in B40.

@Tejas01 I have somewhat opposite to your problem here in Rajasthan they have set preferred B3 than B40 and the phone always latches to it.It is so congested that the full signal bar drops to just 1 bar though the tower is 75 m from my house. They keep it congested as hell. While on B40 without CA I used to get 25-30 mbps.They latch only very small amount of people to B40. When I was in UP B40 was congested. Different circles same problem.

As we are moving towards 5G, I am still unable to wrap my head on how 5G will give us better results on sub-ghz spectrum. Will it be magic? 5g is just a technology, it still needs spectrum to ride on. If the bands are congested then how will speeds be faster?

May sound stupid, but I am thinking of getting a Mediatek Soc-phone and use that Engineering Mode to lock the band to B-3 or any sub-ghz band which is less congested. Frankly, if you are on wifi then anything near 20mbps on mobile data should be sufficient.

Let's see how 5g trials turn out sub 6 Ghz and mm wave have been put up for trial, except mm wave 5g isn't able to provide high 1 Gbps speeds everywhere, 5g could be used to provide wireless home broadband. Currently smartphone companies are using 5g hype to sell useless smartphone which might be useless after 5g launch in the future as the bands can't be unlocked via software.

Spectral efficiency increases. So you'll get a 2-4x theoretical increase over 4G under the same conditions. In a country like India where 4G speeds can average around 12-15 Mbps, the increase brought about by 5G will be maximum 50-60 Mbps at the same sites.

5g could be used to provide wireless home broadband.

There won't really be a need for this actually. Line of sight antennae are using unlicensed 5Ghz band to achieve the same without having to use expensive spectrum. Wireless ISPs (Wisps) will crop up in future, just like how LCOs laying down Fibre PON have cropped up in the past few years. They'll simply enter into revenue sharing deals with tier B and tier A ISPs and improve rural broadband wirelessly using unlicensed spectrum.

We are hitting a man-made economic limit with advancing mobile generations. What I mean is governments are continuing to price spectrum higher for each successive generation, but that economic model is quickly becoming obsolete. The future needs very large amounts of spectrum, but the use cases won't be able to justify the cost associated. So naturally people will fall back to hyper-local networks (WiFi 6 and higher) for bandwidth intensive needs like Augmented Reality and augmented Realtime communications.

The probable use cases for 5G could be dongles/portable Hotspots, POS machines, V2X (automated vehicles network), city-wide traffic light signaling, and mobile broadband (like providing wifi services using 5G backhaul in trains/buses).

Are you serious?? I mean, even after willing to pay additional royalties to Qualcomm? That's a shame and the most impacted will be 1+ Nord. They have just one band(N78)which is a joke in itself and I was thinking they would unlock bands once 5g-spectrum allocation is done. It will be a real shame, it's not that they are having a good time now, practices like these will make users look away from 1+.
Had this been Xiaomi, there would be no qualms. I anyways keep low expectations from Xiaomi.

Also, how well are these radio waves shielded against EM interference?? This could also play an important role in reducing the maximum available speeds on 5g.
