Small talk & Chit chat

I worked with Zhong Fan during my time at UoB, where the West Midlands won the 5G hotbed project, and he and a few others conducted extensive research on V2X's viability for 4G/LTE networks against the 5G networks we had available to us last year, during Jaguar Land Rovers tests with the project. This earlier paper he did some of the work on is a good overview of many of the technologies that go into 5G and their applications
https://arxiv.org/ftp/arxiv/papers/1402/1402.6474.pdf

All the remote IoT projects I've worked on so far that required long range realtime communications are essentially in a permanent prototyping phase till 5G is available. There's only so much local processing you can do with a limited battery capacity(And effective realtime compute is essentially impossible with the latency of 4G.)

But if you look at some of the countries who signed agreements to fund and get 5G developed quicker, or commited to a roll-out several years ago and already laid foundations for its arrival; Indonesia, Mexico, Philippines, Puerto Rico,
Brazil, Honduras, Chile, Argentina, Colombia, China, India, Turkey, UAE, Kuwait, Pakistan, Nigeria, Morocco, ect.
Do these look like all rich countries?

Edit: I think this interesting snippet of history has a little link here:
Heinrich Hertz, upon proving the existence of radio waves, stated that "It's of no use whatsoever [...] this is just an experiment that proves we have these mysterious electromagnetic waves that we cannot see with the naked eye. But they are there."
Asked about the applications of his discoveries, Hertz replied,
"Nothing, I guess."

I mean I hate being that guy but social media, especially for political involvement, is actually quite big in third world countries, and political discourse in many of these nations also occurs through Twitter. It's the main mechanism for charities to communicate and operate with communities amongst other things, used not just because communication is so critical in these environments, with lots of remote or dangerous areas in some, but also smartphones have long been used for payments, taxes and stuff like that in many countries in Africa & Middle East to reduce overheads and avoid tracking issues with insecure infrastructure, social media has also been the key mechanism for political revolutions like 2008's Arab spring. If you look at places like Nigeria, Sudan, ect things like computers aren't practical or cheap, but 2nd hand smartphones from the West absolutely flooded these places a decade ago, while many of these nations have robust wireless networking in place, so they've long become dependant on these pieces of tech in their society as they built infrastructure around it. I'm sure they've all had their fair taste of Twitter idiots, they often satirise Donald Trump's tantrums in the middle east and central asia, obviously he recently claimed he'd "Wipe Afghanistan off the map" quite randomly which gave people in Kabul a giggle.

Its a good read, but its basically the exact same info you get from any $100 basic 5G introductory course.

Thats why you use DCP sims. No need to wait for 5G. We are running pilots at the moment with 5G on offshore rigs. I was there last month installing the sensors. However LTE vs 5G yield same results at the moment. 5G still comes out on top due to the infrastructure being inhouse and the fact that we can "drop" certain platforms from the entire "create session" flow. PCRFs are not required as such (systems that govern your data expenses to prevent you getting an invoice that would trigger a heart attack)

I have however proved that DCP is more efficient and draws less power from the devices than that of 5G. This is due to preprogramming specific networks into the device with preferred network PLMNs as opposed to searching for the best available, and then steered via sim OTA.

The problem right now, is creating data analytical devices that run on small batteries which transmit packet burst at frequent intervals, without draining them in a short space of time. This is out of my hands though and down to the device vendors algorithms.

However if you have the money for it, DCP will do just as good. nbIoT does not need speed it needs an always online status or close to. Downside is that DCP platforms are external solutions with their own mobile core, thus can be pricey.

There is a basic readup on DCP here
https://snmpcenter.com/ericsson-cloud-iot-device-connection-platform/

It even gives a little shout out to my company Telia :)
We are now considered the number one international carrier in the world and have the biggest POP presence globally. There are even 5G programs and tests going on that are too confidential for even me, to get info on :(

also with the exception of two or three. All those countries have a far more advanced network than most western countries. When you lack fibre or todays technology, the best alternative is your mobile network, there is huge funding that goes into these. Kenya Safaricom for example will put any western country network to shame. They are the world leaders in a way given that their banking solution via their mobile network is putting banks out of business.

Apologies for all the total nonsense people. Much of it is boring to 99% of you I know :D. But I'll shut up now, because this isnt small talk at all haha

Yep it's just meant to be a light summary, didn't want anything too mathsy or jargon heavy.

Also yeah from everything I've seen DCP is great if you're a large company with lots of investment capital designing a device for a known area in advance, but when we're talking about say reconnaissance drones for regional UK fire services that are already running on shoestring budgets and made up of volunteers I think 5G is far more realistic given the scale of the roll-out already. It's a good technical solution but the West Midlands 5G test bed was more about testing something on a multi-city scale, for technologies for our national health service, emergency services, security and so on. We had connected ambulances with on-scene video conferencing, smart hospital beds with video links for patients with low mobility to communicate effectively with family outside of visiting hours, live feedback AI-controlled CCTV cameras(I'm sure you know how much we abuse CCTV in the UK) and similar items. Of course as these are all nationalised infrastructure cost is paramount.

Indeed! Although looking into it wouldn't be a good router for my needs as I would want AES-NI support and the Coretex A-72 doesn't seem to support that. I would want that for a router capable of running a VPN and being able to self encrypt/decrypt all the traffic without buying a dedicated VPN box(super expensive)
 
Just took a 3 hour test.

Had to create an api/database/server from scratch with custom non persisting data(only persists on my local machine, not in the api itself) and also deploying it to the interwebs so i can interact with it that way too.

Would be an understatement to say it was easy. Not gonna lie my brain is hurting, not like a headache, like a sharp pain because I was thinking so hard nonstop for 3 hours. Worst part was I was stuck for 2 and a half hours on one function, once I fixed it I had to cram the remaining 80% of the test in 30 minutes. Dear god please never again... :dead8:

Well buddy hope you passed :)

I did barely! What really sucks is I read the instructions wrong, so I ended up making the test FAR harder than what was required, but I wasn't the only one who made that mistake, out of 50 people only 17 passed, everyone was reading the instructions wrong. So they weren't clear for sure. Since the instructor messed up he let everyone retake it who didn't pass using clearer instructions, I don't think anybody failed the retake so far :)
 
Wouldn't be the first time you've gotten the wrong end of the stick and ploughed on regardless :p

Congrats man. You've worked bloody hard at that.
 
Thank you both of you. I was really looking forward to this unit of database/server/API stuff but this instructor so far isn't all that great, compared to the previous instructor. So it's kinda ruining it for me. Just got to try harder and do some self-learning I guess.
 
Yeah with classes with bad instructors you have to get more critical I think and if you have the opportunity ask lots of questions especially if they're being vague as usually most other people will be in the same boat and wondering too, if you get a lot of work to do outside of lessons I think it's super useful if you do group work with others in the class after you've attempted it, if you have facebook group chats or something that helps a lot to suss out mistakes or the meaning of vague bits, and it at least gives other perspectives on questions and stuff.

If he one of those guys who just doesn't seem that into it when he goes through things there might be good material online that's worth using as same day after-class revision too, it's abit long but can help a lot, with coding especially ofc just doing examples is a great way to learn.

Just heard that Alex Albon, a kid who went to school with my friend, has got his full Red Bull F1 drive half way through his rookie season. Really great achievement but he's been oozing talent all season, looks like Red Bull will be overtaking Ferrari by the end of the year.
 
So at my school every 4 weeks we get to choose 6 projects we would like to do. Get randomly assigned one of those projects with other random people and to then make it in 4 1/2 days.

I got my 6th option of course.. lol
But it was an easy project, my first 5 were harder, similar but had little kinks to them. So it kinda sucks as I was hoping for more of a challenge. I completed 90% of it over the weekend so my web engineers could interact with my database/server. Just so they didn't have to wait for me to get it up and running and fall behind(worst thing ever from personal experience). But finished up last night. So got 2 days off easy now.

To make it harder figured I would just refactor my entire database from SQLite3 to something else. Doesn't seem to be to much work for 2 days. Although I say that now until I get stuck with no time left :D

Dipped my toes to the used car market since there was a clean-looking and low mileage cheapo 106 nearby. Liked the car, and it seemed solid enough without rust in common spots. But opening the coolant cap revealed oil in a place where it doesn't belong. :(
