00:00:00.080 --> 00:00:07.600
you know i think we'll start by defining what the heck a g is

00:00:05.279 --> 00:00:12.320
yes i suppose it is that but it also refers to the generation of cell phone

00:00:10.639 --> 00:00:17.760
network technology used by your provider's towers and the radio in your

00:00:14.960 --> 00:00:23.680
mobile device so how many g's you have affects the features speed availability

00:00:20.640 --> 00:00:27.760
and reliability of your mobile network

00:00:23.680 --> 00:00:30.000
so 1g or first generation was analog

00:00:27.760 --> 00:00:34.800
it didn't even support roaming didn't encode voice calls digitally and had no

00:00:33.120 --> 00:00:38.719
support for mobile internet which i guess makes sense since that was pretty

00:00:36.640 --> 00:00:44.160
much sci-fi when 1g was rolled out starting in the early 80s at any rate

00:00:41.120 --> 00:00:46.559
good riddance to it it's successor 2g

00:00:44.160 --> 00:00:51.200
rocketed us into the digital fast lane allowing voice calls to be transmitted

00:00:48.960 --> 00:00:56.480
more efficiently via compression which you can learn more about here by the way

00:00:53.520 --> 00:01:01.680
and cell phones to become smaller thanks to the reduced radio power requirements

00:00:59.199 --> 00:01:06.880
awesome what we also got with 2g was confusion roaming to different

00:01:03.920 --> 00:01:10.960
territories was much improved but only if the mobile network you were roaming

00:01:08.560 --> 00:01:17.439
on used the same type of second generation network the main two of which

00:01:13.040 --> 00:01:20.320
being cdma and gsm and while initial

00:01:17.439 --> 00:01:23.280
true 2g offerings were too slow for a mobile internet experience beyond

00:01:21.840 --> 00:01:28.720
text-based emails interim standards like gprs and edge

00:01:26.560 --> 00:01:34.240
colloquially referred to as like two and a half g or 2.75 g could deliver data

00:01:32.079 --> 00:01:38.880
rates as high as well much higher than the minimum 200 kilobit

00:01:36.960 --> 00:01:45.520
per second transfer speed required to call something 3g which is why the line

00:01:42.640 --> 00:01:50.720
is so blurry because carriers had to try and balance backwards compatibility and

00:01:48.399 --> 00:01:55.040
future proofness with performance and coverage today not an easy thing to do

00:01:53.520 --> 00:02:00.479
when you're trying to save all that money and third generation or 3g

00:01:57.680 --> 00:02:04.880
networks didn't simplify matters at all with technologies like edge being

00:02:02.640 --> 00:02:08.640
technically allowed to be marketed as 3g thanks to fulfilling the speed

00:02:06.000 --> 00:02:13.280
requirements even though almost no one did that since it's an upgrade dead end

00:02:11.280 --> 00:02:18.560
and not at all competitive with standards like wcdma whose later

00:02:15.920 --> 00:02:24.160
upgrades like hspa and hspa plus could achieve pretty kick-ass mobile broadband

00:02:21.360 --> 00:02:28.319
speeds in excess of a hundred megabit per second

00:02:25.680 --> 00:02:34.000
okay so deep breath did 4g fourth generation make things

00:02:30.879 --> 00:02:36.959
simpler the answer is yes and no the

00:02:34.000 --> 00:02:40.160
term 4g is used pretty fast and loose by cell phone providers for one thing who

00:02:38.959 --> 00:02:44.959
are trying to convince you that they have the fastest stuff but it also has a

00:02:42.879 --> 00:02:49.840
few different real meetings so some companies use 4g to refer to a standard

00:02:48.000 --> 00:02:54.800
called hspa plus which if you remember from like 20 seconds ago is actually

00:02:51.840 --> 00:03:00.160
technically turbocharged 3g which is why many carriers now are differentiating

00:02:57.360 --> 00:03:04.720
their long-term evolution or lte networks by specifically calling them

00:03:02.239 --> 00:03:09.760
out as 4g lte lte offers enhanced voice quality with

00:03:07.200 --> 00:03:14.480
hd voice which you can learn more about here and dramatically better downstream

00:03:12.400 --> 00:03:18.800
data rates for watching youtube videos and streaming from music services like

00:03:16.480 --> 00:03:22.560
spotify we're talking up to 300 megabit per second and on top of that you can

00:03:20.879 --> 00:03:26.640
see dramatically better upstream performance too which is critical for

00:03:24.319 --> 00:03:32.720
video calls and even mobile gaming in some cases but then is 4g lte the end of

00:03:30.400 --> 00:03:38.560
the huge alphabet soup of different wireless names the answer is no i mean

00:03:36.480 --> 00:03:45.360
there's a newer version of lte called lte advanced that is being marketed as

00:03:41.680 --> 00:03:46.799
true 4g since lte wasn't technically 4g

00:03:45.360 --> 00:03:52.080
then they kind of changed the rules so they could call it that for marketing purposes

00:03:49.760 --> 00:03:57.360
so that's on the horizon offering even greater reliability due to its use of

00:03:54.560 --> 00:04:02.239
several different lte frequency bands at once which is very important when you're

00:03:59.840 --> 00:04:06.799
traveling around or in a densely populated city also there's one company

00:04:05.280 --> 00:04:12.159
in south korea that has already rolled out what it calls giga lte which is

00:04:09.920 --> 00:04:16.799
today capable of speeds of over one gigabit per second on compatible phones

00:04:14.560 --> 00:04:21.600
from samsung and lg absolutely incredible as long as there's

00:04:19.280 --> 00:04:25.440
a nearby tower so speaking of nearby towers will this kind of performance

00:04:23.680 --> 00:04:28.720
ever be available in the technologically backward west

00:04:26.720 --> 00:04:32.080
well perhaps not but at least those of us stuck under the oppressive heels of

00:04:30.400 --> 00:04:35.280
our local carriers can take comfort knowing that the next generation of

00:04:33.840 --> 00:04:41.520
south koreans will be enjoying the latest freemium games in glorious 4k

00:04:38.960 --> 00:04:46.479
speaking of latest freemium games have you ever thought to yourself gee if only

00:04:43.280 --> 00:04:48.720
i had some like graphic design skills

00:04:46.479 --> 00:04:53.840
and some business savvy and some coding skills i could make a freemium game and

00:04:51.120 --> 00:04:58.240
like swim in my buckets of money all day well lynda.com is there for you i mean

00:04:56.400 --> 00:05:01.919
fortunately they have actually lots of different things you can learn word uh

00:05:00.160 --> 00:05:06.400
