What will Succeed Wi-Fi and why: Indoor Optic Mesh Ti-Fi

Recently, on September 28 2021, I gave a brief presentation at the famous Wireless Optic Communication Conference (#WOCC), Eindhoven, but presented online. The conference lectures can be seen at https://www.owcconference.com/previous-editions/

  1. The video of my 15 minutes lecture is available at : https://www.youtube.com/watch?v=yP0cejGcxik.
  2. The Paper it self can be downloaded from this URL:

3. My view on what drives the ongoing huge growth in Bandwidth Demand is as follows.

In my paper I have shown a drawing with on the right side a Computer Bus with Chips (like cpu’s) connected that do CONTENTION on the Bus/backplane, consisting of multiple parallel wires. Only one chip at the time can do a call or answer on this Bus. Further to the left there are a number of other “places of contention for connection resources”: The I/O interface, the USB (universal serial Bus) cable, the hub/router, Ethernet cables, the outside optic fiber link with Ethernet like traffic (VLAN), a level 2 Switch, wide area links, level 3 routers, etc. all the way to server farms of Cloud Services. At each of these “places of contention” digital traffic (streams of IP packets) are filtered (Bus calls are not sent all over the network) and handled localy, so only data that is destined for longer distant servers is passed through. This also means that the long distance link speeds do not have to be designed for the addition of the device (like Laptop) speeds. The architecture i propose can handle a number of local indoor 1 Gb/s devices on one 1 Gb/s link from the network provider/ ISP.

My most important message is that Telcos & cableco’s & network access providers should notice who their CLIENTS are: the new superpowerful CPU’s and GPU’s !!! Like from Intel and Apple Mx. These millions of IC’s will drive bandwidth demand, and ……will need optical Ti-Fi. It is not only the people who experience occasional slow network speed but their computers, and even more specific the CPU chips inside them who get restless.

Let me explain this in more understandable terms. If you open an online webpage on your screen then, DEPENDING ON THE NETWORK ACCESS SPEED, the App working on the CPU tries to get connection to a number*) of internet addesses to get blocks of info and or pieces of film to put on the screen. The App and the CPU want reactions to their request and one of them is delayed it repeats the request. etc. etc. The cpu is pushing and pushing very unforgiving until the answered pieces are on the screen. If the speed of the connection is better the number*) of outstanding requests is increased, with adds or suggestions to the page. In that way a slow line does not seem very bad. It just gives the impression of slowly filling screens, not showing its incompleteness. In other words, the billions of recent Faster CPU’s from Apple computers and Intel are driving bandwidth demand.

This project fits in the long time trend of changing networks from Electronics to Photonics (#Fotonica). In other words from moving Electrons to moving and switching Photons.

This Ti-Fi project is an example a rare “Moonshot Project”(vital breakthrough), as defined by powerlady Mariana Mazzocato. So is RedGrid.io and IOEN.org in Australia and #Holo in Turkey. During WWII in the UK that was Radar.
