867-5309 … some of you might be old enough to remember this song from Tommy Tutone dating all the way back to 1981. That was nearly 40 years ago, but strangely enough, I remember that phone number. And I also remember phone booths, pay phones and the ability to go to the phone store and get a new phone to match the new color of my bedroom. But enough nostalgia ...

“Magic mirror on the wall, who is the fairest one of all?” These days just look to your augmented reality mirror to get all the answers and more! CES never disappoints in showcasing new, cool (and even ridiculous) technology, but for 2019 there was more tech related to beauty – including artificial intelligence, virtual reality, 360-degree video capture, facial recognition, and even 3-D printing – than ever before ...

I first came across the reference to Super-PON back in 1996 at an IEEE Communications Society Conference. At that time, Super-PON was described as supporting a split ratio of 1:1024 at a range of 100km. The overall network capacity of the Super-PON was 2.5Gbit/s TDM downstream and 300Mbit/s ATM-based TDMA upstream and it introduced the concept of optical amplifiers along the fiber paths. At the time this was particularly forward thinking, as the only PON systems that had been deployed were BPON systems supporting a split ratio of 32 subscribers and a capacity of 622Mbit/s / 155Mbit/s. For reference, GPON can support a split ratio up to 1:64 at a range of 20km with a network capacity of 2.5Gbit/s / 2.5Gbit/s ...

The ITU recently announced the formation of Focus Group Network 2030 (FG NET-2030) with the goal to study the requirements for networks beyond 5G. Targeting the year 2030 as the timeframe when forward-looking scenarios such as holographic type communications, volumetric video and haptic applications will be commonplace, this new focus group hopes to answer the question: What will this network architecture look like and what are the enabling mechanisms to enable these scenarios?
