5G Reality Check - Data Rates

One of the common questions that we encounter is why are 5G speeds so low as we were promised 5G downlink speeds of 20 Gbps. Most people do not understand how the 5G speeds are calculated and what do they depend on. In many cases, the network won’t be capable of delivering higher speeds due to some or the other limitation. 

In a new presentation, I try to explain the theoretical speeds and compare them with real world 5G data rates and even try to map it to why these speeds are what they are. Hopefully people won't mind me adding some humour as I go along.

Opinion – 5G Reality Check: Speeds from 3G4G

Embedded below is the Twitter thread on Speedtests 😂

Speed Tests are 5G killer app 😉, @HarriHolma provides details in replies: Elisa 100 MHz 5G (8T8R radio) on 3.5 GHz with LTE dual connectivity (EN-DC). LTE phone gives 200-250 Mbps in the same spot. The configuration uses L800+L1800+L2100 #5GKillerApp https://t.co/5ZnS2UeFkL

Some interesting April Fools' Day 2018 Technology Jokes

This year April Fools' Day wasn't as fun as the last one. Couple of reasons being that it was on a Sunday and it coincided with Easter Sunday. Here are some of the jokes that I found interesting.

Sprint's Magic Ball:

It was good to see that the US mobile operator joined the party this year. Their magicball (based on their highly successful Magic Box) advert was really good. Here is the video:



Good to see that they managed to squeeze in references to 5G and small cells

T-Mobile Sidekicks Re-booted:

T-Mobile USA has consistently come up with the best tech pranks. Last year they had the OneSie with Human HotSpot and BingeOnUp the year before. This year the re-booted sidekicks was the joke of the day. The video is embedded below. As the description says, T-Mobile’s Sidekick gets a remake! Inspired by the past but stepping boldly into the future, it has revolutionary AI, headphones that double as chargers, personalized GPS guidance by John Legere, and more!

The Chegg Osmosis Pillow:

"A top-secret team of Chegg engineers from Zurich spent two years developing a new patent-pending revolutionary proprietary method of making memory foam using special blends of matcha and lavender. Thanks to their discoveries, Chegg’s memory foam actually improves your memory. Got a final exam tomorrow? Sleep on it. Got a lab report due? Sleep on it. Need to outline your entire thesis? Sleep on it."

Official Website: https://www.chegg.com/play/memory-foam-pillow/


Pindrop TonguePrinting:

"Tongueprinting technology analyzes thousands of tiny bumps called papillae, as well as factors such as shape, size, and temperature to accurately identify yourself by licking your phone. This technology will be the mouthpiece of Pindrop’s latest authentication and anti-fraud solutions." Video:


Official website: https://www.pindrop.com/resources/video/video/tongueprinting/


Roku Happy Streaming Socks: "Do messy snack hands keep you from using your Roku remote? Meet the new Roku Happy Streaming Socks with built-in motion sensors, plus toe-toasting and anti-loss technology."

Some interesting April Fools' Day 2016 Technology Jokes

When I posted April Fools' jokes on the blog last couple of years (see 2014 & 2015) , they seem to be very popular so I thought its worth posting them this year too. If I missed any interesting ones, please add in comments.

The one I really liked best is the Samsung Internet of Trousers (IoT) featuring:

Wi-Fly: Gone are the days of unnoticed, unzipped trouser zippers upon exiting the restroom. Should your fly remain open for more than three minutes, the ZipARTIK module will send a series of notifications to your smartphone to save you from further embarrassment.

Get Up! Alert: Using pressure sensors, Samsung’s intelligent trousers detect prolonged periods of inactivity and send notifications to ‘get up off of that thing’ at least once an hour. Should you remain seated for more than three hours, devices embedded in each of the rear pockets send mild electrical shocks to provide extra motivation.

Keep-Your-Pants-On Mode: Sometimes it’s easy to get carried away with the moment. The Samsung Bio-Processor in your pants checks your bio-data including your heart rate and perspiration level. If these indicators get too high, Samsung’s trousers will send you subtle notifications as a reminder of the importance of keeping your cool.

Fridge Lock: If the tension around your waist gets too high, the embedded ARTIK chip module will send signals to your refrigerator to prevent you from overeating. The fridge door lock can then only be deactivated with consent from a designated person such as your mother or significant other.

Microsoft has an MS-DOS mobile in mind for this day. I wont be surprised if a real product like this does become popular with older generation. I personally wouldn't mind an MS-DOS app on my mobile. Here is a video:

It would have been strange if we didnt have a Robot for a joke. Domino's have introduced the Domimaker. Here's how it works:

T-Mobile USA is not shy pulling punches on its rivals with the Binge On data plan where it lets people view certain video channels without using up their data. Here is the video and more details on mashable.

Google had quite a few pranks as always. I will ignore 'mic drop' which backfired and caused them headache.

Google Express has a new delivery mechanism, just for the April Fool's day. (There has to be one drone idea)

Google Cardboard Plastic is an interesting one too. Here is the video:


Finally, its the Google Fiber Teleportation.

Some interesting April Fools' Day 2014 Technology Jokes

Its very interesting to see all the companies proposing very interesting concepts on the 1st of April. I was told that not everyone knows what April Fools day means so here is the link to Wikipedia.

Samsung Fly-Fi: Samsung has come up with some interesting ideas, the first being Wi-Fi for everyone powered by Pigeons. They have a website here with Video.




Looks like since we have Pigeons everywhere, so they are always used in one way or the other. The best prank ever in my opinion was the PigeonRank by Google, back in 2002. I spent a few hours that day trying to figure out how they were actually doing it.

Smart Wear was always going to be the big thing. Quite a few smart wearables this year.

Bonobos has done a good job with with TechStyle. See video below:



Samsung has a glove called Samsung Fingers here. The best thing I liked was 'Talk to the Hand'



HTC came up with similar concept called Gluuv



Toshiba's DiGiT is as interesting. See the video:


Virgin Mobile, Canada has come up with SmartKicks. See here.



Roku Watch is not too bad:


Virgin America even convinced Sir Richard Branson to appear in the April Fools ad along with Tony Faddell, the CEO of Nest. Funny Youtube video here.

Sony Power Food was just okay, video here.

Toshiba Spehere is a funny Gaming concept, see here.

Nokia reviewed its most popular phone 3310 with modern day features here. Coloured screen with 41Megapixel camera.

Google wants to Emojify the web here.

Google Japan has a magic hand here.

Selfiebot by Orbotix is a cool concept, here.

Twitter Helmet didnt make me laugh though. See here.

Is there some others that I missed? Please feel free to add it in the comments.

Rise of the "Thing"

Light Reading carried an interesting cartoon on how M2M works. I wouldnt be surprised if some of the M2M applications at present do work like this. Jokes apart, last week the UK operator EE did a very interesting presentation on Scaling the network for the Rise of the Thing.

A question often asked is "What is the difference between the 'Internet of Things' (IoT) and 'Machine to Machine' (M2M)?". This can generate big discussions and can be a lecture on its own. Quora has a discussion on the same topic here. The picture above from the EE presentation is a good way of showing that M2M is a subset of IoT. 

Its also interesting to note how these 'things' will affect the signalling. I often come across people who tell me that since most M2M devices just use small amounts of data transfer, why is there a need to move from GPRS to LTE. The 2G and 3G networks were designed primarily for Voice with Data secondary function. These networks may work well now but what happens when the predicted 50 Billion connected devices are here by 2020 (or 500 Billion by 2030). The current networks would drown in the control signalling that would often result in congested networks. Congestion control is just one of the things 3GPP is working on for M2M type devices as blogged earlier here. In fact the Qualcomm presentation blogged about before does a decent job of comparing various technologies for IoT, see here.

The EE presentation is embedded as follows:

Scaling the Network - Rise of the Thing from Zahid Ghadialy

Another good example website I was recently made aware of is http://postscapes.com/internet-of-things-examples/ - worth checking how IoT would help us in the future.

Humour: 5 Stages of Bug Fixing

The above Dilbert strip is a reality for a lot of us, everyday. There are many bugs in each product and we only have a limited amount of time and resources that can be dedicated to fixing bugs. The '5 stages of bug fixing' was presented in one of the Cambridge Wireless events not long ago. I am not sure if allowed to mention by whom, so here it is anonymously.

The five stages of Bug Fixing

If you think about it from the Tester's point of view, this is what he prays for everyday. See the old post here.

M2M and the 'Big Data'

Couple of months back, there was this Dilbert strip on the big data.

Apparently, Social networks, M2M devices and many other sources of data, keeps on generating data all the time. This data can provide us with a lot of useful information if proper analytics can be done on it. This is a real challenge in guess. There will also be security and privacy implications that may decide how and what can be used and by whom.

Here is a simple introductory video by Intel explaining what Big Data is:
