Why is 5G a Game Changer? - 6 Minute Blog

Picture
G'day everyone.  Today is blog Friday. So today.....I'm going to talk about 5G networks.

5G stands for fifth generation (5thGen) networks. When I say network, we mean mobile phone network. It's basically the fifth generation of mobile phone network, after 3G and 4G.

What does that really mean?  Well....it means you're about to get super super fast speeds, with a very low amount of delay.  Speed is measured as bandwidth in gigabits per second (Gbps).  Delay is measured in milliseconds (ms) as latency.

The great news for gamers, remote communities and all consumers of apps in the cloud, is that it poses a serious alternative to technologies like ADSL2.  ADSL2 is also known as broadband. In Australia in particular, we have something called the National Broadband Network, known as NBN.  Which is meant to provide highspeed broadband.

To be fair, it hasn't really delivered the speeds and service quality the government promised.  In fact....it's been......a disaster.  So let's redesignate the NBN acronym to.....Nil Bandwidth Network.  😂 

Check out the awesome cartoon taking the mickey out of the entire saga, copywright of Westpix:

Anyway...moving on....   According to Wikipedia, which is one of my favorite resources for learning, 5G networks are digital cellular networks, that are divided into smaller geographic areas.  These areas are called cells.

These cells, allow mobile phones to seamlessly connect.....to different areas of the network. So as you move across different locations, you're able to move between cells. This  gives you seamless coverage, and provides you with uninterrupted speed with minimal latency (delay).

The main advantages of using 5G are:
  • Download speeds are significantly faster through higher bandwidth allocation.
  • Delays on the network are much lower due to lower latency.

​Let me use some real data, based on the AT&T 5Gn network.  This is taken from the CNET article below:
Picture
The testers in this article were gaining at least 1.4 Gigabits (Gbps) per second. To give you an idea of how fast that is......your current ADSL2 connection is capable of 0.02 Gbps per second maximum.  You're more likely using 0.01 Gbps.  So 5G, is 140 times faster. 

This article is specifically measured in the US.  In other countries, bandwidth and latency it will vary.  So the speeds are dependent on the quality of the infrastructure, the spread of the population across a country and the investment needed in each country. 

For example, in Australia, we'd be looking at lower speeds. But I would typically be expecting a speed of at least 0.2 Gbps once the rollout is maturing towards the end of 2020.  Unfortunately in the early part of a rollout  in Australia, it's likely to be a lot less.  But even if we only get 0.1 gbps, that's still 10 times faster.  You can check out my mental arithment below...courtesy of Uncle Google.  The Uncle you can't do without....and is less embarrassing at family parties...😂
Picture
The next question everyone tends to ask is why would you want 5G.  Well...imagine this situation.  You're living in a  a remote community in outback Australia.  Kangaroos and Koala Bears are running wild. Running cables out to say...Woorabinda....no I didn't just make that name up....is going to be very expensive.  It's also unlikely to provide a reliable and high bandwidth solution.

But wait....5G offers a very cost effective alternative. This means that remote communities are not at a disadvantage and benefit from improved services, higher quality of life and better health outcomes.

A core use case to help improve health outcomes in remote areas is the use of Telehealth services. Telehealth services, allow patients and doctors to interact and collaborate effectively to help solve health issues.  In a 5G network it would not only provide a reliable high-resolution video link. It would also allow the transmitting of complex medical information in real-time. 

This would save a patient driving many hours to see a medical practitioner.  A 12 hour drive in remote areas is not uncommon.  A far cry from Brisbane city dwellers moaning about a 40 minute rush-hour commute into the city.  😂

So a telemedicine capability would be able to stream live video between a doctor and a patient and resolve various medical conditions.  

Other use cases for 5G include:
  • The use of a network to help autonomous cars communicate with each other.
  • Having better connected Smart Cities and better connected Smart homes. 

With all of our devices connected to the network, humans can make better decisions, based on advanced analytics.  This helps improve our lifes and lifestyles....and allows us to become more sustainable.  Because our kids deserve a cleaner planet....right?  😎

Check out the use cases from Ericsson:
Picture
More importantly from an everyday perspective, if you're living in a metropolitan area, 5G is now a serious alternative to broadband, 4G and other networks like NBN.

It also allows us to change our lifestyle. So 5g would allow us not only to have high speed internet at home but also have that mobile speed as we travel.  Quite simply, you could have a network that effectively follows you around, which means the paradigm of working from home or working from office is fragmented further....which means people like me who do a lot of travel can do more with less.  Lean is good.  😎

I consider myself a road warrior.....I'm constantly traveling Australia, running courses....so this type of technology is a game changer. It means I can carry more of my apps with me, and do a lot more with them in faster time frames.

​It's a huge differentiator for me and allows me to gain an advantage over other coaches and other training companies.

Smart vehicles is a little bit into the future, however without a 5G network, those innovations would never have happened.  Just like Netflix and Spotify would not exist without Amazon Web Services and cloud computing. 
Picture

In order to see autonomous smart vehicles, we are going to need a very reliable, high speed network that is available anywhere.  5G is an important platform for this type of innovation.

Finally, a very important use case will be human machine interaction.  If we are able to interact faster with our devices, such as using virtual reality or augmented reality, then then we can communicate more effectively between each other using more efficient methods.  Less....is clearly more!

The picture below is a rendered picture of a real hologram table.  It's real, because I've used it.  5G would open up the possibilities of using this technology in real-time between multiple people....in different locations:

CyberSecurity FEatures in the Tesla Model 3

Picture
Welcome back everyone and I hope you've had an awesome week.  Today I'm going to outline some of the really cool security features in my Tesla Model 3.  This blog is inspired by my good mate Marty, who was very interested in some of the Tesla security features. 

​First of all let me outline the five areas I'll cover:
  • Software Updates - how do you update the car's software and is it safe?
  • Sentry Mode - this is the mode you use to protect your car from vandalism or theft.
  • Dashcam - perfect for recording that accident that simply was not your fault.
  • Pin to Drive - mult-factor authentication for cars.
​Before that...let me share with you, my latest video on YouTube, demonstrating the Pin to Drive and Automatic Lane Changing feature which is part of the Enhanced Autopilot.
I also wanted to share a link to an awesome new course that I'm very excited to launch with ALC Education & Consulting.  It's a 3 day course leading to the Enterprise Big Data Professional certification, where I'll share all my personal Tesla, SpaceX and NASA personal stories.....
Picture

Software Updates

For everything that Tesla does...safety is their priority.  Software updates are optional...in fact there is an option to be an 'early adopter' of updates or just a 'regular adopter'.  I've gone for the early option which is setup on the system page of the Tesla.  This means I will receive all the updates as soon as they are ready.  

Firstly, the car must be stationery and in park.  Secondly I need to be connected to a strong WIFI signal.  Thirdly, it's also a good idea to be charging at home.  So there are zero risks of updates whilst driving.  I've done 3 updates in only 30 days of having the car.  Each one took around 25 minutes, was flawless and gave me a heap of new features.  Overnight whilst charging is the best time to do them.

Yes...Tesla software updates are 100% safe.  The Spotify App was added in the latest version 10 of the Tesla Model 3 software updates.....

Sentry Mode

This is great when you leave your car in a car park or on the road, and you're worried about security.  Once your phone is out of range...or you have locked the card with your key and walked away...the sentry mode is active.

Whenever someone approaches the car, all the cameras pick up the movement and start recording.  This is after it warns you as the headlights flash quickly....just like the flash on a speed camera.  Recording stops once the system is satisfied the threat has gone away.  The picture below shows the pulsating red dot when the cameras fire and it periodically displays the words "Sentry Mode Enabled"...or words to that effect.
Picture
If the person is very determined and tries to break into the car....the alarm sounds and the owner is notified on the Tesla App on their phone.  I've fortunately never had to test this feature.

The footage from the cameras, when Sentry Mode is activated is stored on a USB that needs to be plugged into the car's internal USB ports.  Unfortunately the only way to view the footage is to plug the USB into a PC.  I'm sure Tesla are working on a feature to make the USB material viewable in the car itself.

Dashcam

Pretty straight forward really....the car will record 60 minutes of footage from all the cameras in the car.  So if you were to have an accident...you simply hold down the dashcam icon button and it saves the 60 mins of footage to the USB key.  Simple really.  Below is a picture showing the dashcam recording.  Denoted by the red dot.
Picture

Pin to Drive

Even when you have the Tesla key, which is a card, or the app which authenticates you as the geniune owner of the against the vehicle, it's possible that if someone steals your key or mobile....then they can drive your car.  So, I've enabled a feature called Pin to Drive, which means I need to enter a pin password before I can take off. 

We call this two-factor authentication.  Something I have....which is the key card or mobile phone.....and something I know.....which is my PIN.  The car also has an internal camera, so I'm sure in the future, it'll be possible to identify the driver using biometrics.   This is a 3rd factor of authentication and we call this something you are. 

You could also use geolocation as another factor.  I've setup Tessa to fold the car's wing mirrors as I approach my garage.   Extra safety measure that minimise the risk of clipping my mirrors.  Tesla think of everything.

Wrap-Up

That's it from me this week.  Feel free to share this blog post and the new Tesla video.  Have an awesome weekend.
