Everyone Should Know About 5G
What is 5G?
5G means the fifth generation of cellular networks, and like we have seen 2G, 3G, and 4G in the past, the primary assumption of 5G is that it offers much faster speeds for download and upload. It’s also able to reduce the latency in the connection as well now theoretically 5G can achieve crazy high speeds, and many people across the world have even shown in their speed test that they can achieve speeds of 2 GB per second.
for example, I have a fiber connection at home that just does 1 GB per second you know while 1 GB per second is also amazing and kind of overkill. for all intents and purposes 90% of the individuals who utilize their cell phones or you know other associated gadgets.
it still is great to have and in order to reduce the amount of time that you spend on downloading something and uploading something or kind of reducing the amount of time that it’s needed to buffer a particular video particularly in terms of higher quality content now.
What is Disadvantage of 5G?
First and foremost is that 5G is very hardware dependent. You cannot release a software update, thereby enabling 5G on devices that 4G, 3G, etc. 5G is a hardware-dependent feature that requires a 5G modem on your device, and without that, you can’t connect to a 5g network.
5G uses MHz frequency in order to transmit the radio waves onto your smart phones 5G is very different because it uses millimeter waves now millimeter waves is very similar to what you get on Wi-Fi so you have 2.4 GHz Wi-Fi, 5 GHz Wi-Fi etc. so this also relies on similar GHZ frequencies in order to transmit data onto your smartphone so it makes use of 24 Giga Hertz all the way up to 100 GHz depending on the implementation in order to do it.
And like you may have guessed the disadvantage to this is in terms of the range in terms of the basic coverage itself so if you notice in your home if you have a dual band Wi-Fi out of example you’ll notice that the 2.4 gigahertz band actually goes further so you go to the furthest corner from your router you would probably notice that you won’t be getting any 5G signal.
if you have a regular router if you have a really powerful router you’ll still notice that the 2.4 gigahertz band has more range or more reception compared to the 5 gigahertz band and that’s simple physics because higher-end you go in terms of frequencies the lower the range or the distance that they can travel .
5G more like you’re considering Wi-Fi rather than having it like a tower so what happens in the case of a regular cellular tower is that it goes to a much wider area of coverage compared to the 5g node and as a result 5G node basically needs much more units to be placed all around in order to have full coverage.
So the other issue with 5G is that if you have one node here and say the next node a kilometer away you will have a point in between where there is no connection whatsoever so you won’t be able to go from one 5G spot to 5G like you have 4G in cities like Bangalore for example so in order to truly have proper 5G coverage what you need to do have a lot of nodes imagine spider-man spider-man weaves as web holds onto one and by the time he is about to leave he goes on to the next one.
So you need to have that sort of a connection between the two a slight overlap to make sure that there is no dead spot in between these and you don’t switch back from 5G to 4G in between now assuming that we figure out that part.
The other limitations or the other problems of 5G is basically heating so your device tends to heat quite a bit especially if the 5G connectivity sort of fluctuates quite a lot considering is using millimeter waves and the fact that you can easily lose the connection to 5G say you switch back to 4G your phone will still be hunting for 5G.
There’s a very high chance that it will start to overheat as well so if you guys remember back when 4G launched initially as well the number of 4G towers was very limited the kind of coverage was also very limited so even if you put it in 4G mode it kind of always kept searching for 4G networks where you know you only had 3G networks.
For example and that made the phone heat up more than it should actually have done and it also led to battery blame which is why most of the fighting implementations you see are on smartphones which have a larger battery capacity compared to regular smartphones though s10 plus 5 G for example has around 400 mAh more than the as regular s10 plus variant so you need a larger battery.
It also comes with heating and most importantly the current implementations of 5G don’t really have 5G upload speeds so while theoretically you can have crazy download speeds currently and people are getting it as well when all the you know factors and all the other variables align perfectly together the upload speeds are still not that impressive the applause speeds are still maybe one tenth of what you get at maximum from the download speeds on 5G.
When will 5G come in India?
We know the general mentality of us Indians is like we like to make an investment for a while and we like to change stuff only when there’s something wrong with and not just to show off or to have bragging rights. We don’t change the devices so the negatives are the issues that India would face is first of all the 4G you know coverage in India itself is not 100%.
India is a huge country and you know I’m sure that getting 4G across to 100% of India is practically impossible. There will be areas that have dead spots etc. So even if you’re looking at having 5G and say the metropolitan cities or you know even larger towns as well it still needs a lot of infrastructures to be present in order to have true proper coverage and that’s gonna be really expensive.
And that cost is gonna play a huge role in determining when we will see a 5G rollout in India considering that the telecom operators are already on a huge loss they’re having huge losses because of the competition which is driving them further down to decrease the rates and India currently has the cheapest data plans and cellular plants in the entire world and you know that’s costing telecom operators a lot of money.
We could possibly see 4G services becoming more costly in India and if and when 5G services come we could see that that also will have a higher premium over the 4G services in India but because of this lower disposable income and because of the higher cost that’s going to increase it is very little and the fact that they’re making losses, of course, there’s very little incentive.
For these brands to actually release 5g networks in India. Even when 5G actually rolls out another issue that these telecom operators need to tackle is in terms of the congestion so India is a country that’s densely populated and certain regions such as Delhi NCR. for example a place like Bangalore which itself is a densely populated and densely crowded place.
So this congestion causes a lot of difference in terms of the theoretical speeds that one can achieve and if you look at the speeds that we are getting on 4G in India that’s kind of like what you used to get with 3G in the initial days on most days I get anywhere between 10 to 20 Mbps which is not much.
And I remember during my initial days of testing of 3G I used to get the same results on 3G itself so of course the latency has gone down and when things fall right you get much higher speeds I’ve gotten up to I think 70 in the initial days of Jio when they were launching it so that’s certainly impressive and definitely when 5G also comes about it will bring about a huge change and a lot of scope and potential for much faster download speeds lower latency and also could help you know bring about certain advancements.
In technology such as autonomous driving cars with low latency they can talk to each other minimize the risk minimize the issues or the possible issues that could happen with decrease in latency and stuff like that but those are things that are very very far away right now keeping all these things in mind about the condition of the telecom operators the cost at which they are providing services is too low.
And yet the Indian consumer the mindset of Indian consumer is that they don’t want to spend too much at the end it seems like five years roll out although brands might have ID enabled smartphones in 2020 I would kind of say that a proper 5G rollout will be too 21 or even 22 at the very least in terms of a proper fight you roll out where people can technically say that they’re using file enable smartphones and using it daily for for you know their personal use instead of just going to say shop and just testing fighting speeds just to post the speed test results.
Now I also took some statistics for my friend who lives in London he’s on 5G network and he is using 5G and even for him he doesn’t have a hundred percent 5 G coverage and his results were somewhat mixed at times he got closer to finite Mbps but most of the time he got around 300 Mbps in terms of download speed with 5g and of course it should improve with time but then again even in London a city like London there’s not had a percent coverage so it will definitely take some time for it to come to India.
Now the question as to whether you should buy a fuzzy smartphone now or say even next year I would say it’s always best to let technology mature and come to a point where it’s better so 5G smartphones now won’t be as good as the 5G smartphone coming next year or two years from now.
There’ll be much better in terms of heat in terms of the they’ll be much better in terms of handling the issues that I told earlier in terms of the battery drain so they should have larger battery capacities by then or find ways to cram a larger battery into the phone they should be more efficient as that as well they should also be more efficient in terms of heating or thermal efficiency should be much better by then.
And lastly you know it’s always best to buy a 5G smartphone once the networks themselves are ready for it others you you’re gonna invest more and end up not using what you bought the smartphone for in the first place so people who buy 5G smartphones and bring it to india now they won’t be able to use it up until the time that 5G network actually rolls out and by then there is a high chance that they would want to move on to another phone so that extra bit of money that they invested in it goes to waste so you shouldn’t buy a 5G smartphone India now.
