Owner’s Objectives

It's been a while since I expressed some of my objectives for the CC . First of all I like and respect everyone that joins our club . I realize that not everyone knows what a CC is all about . Many have different reasons for joining . I really don't know how many of the other clubs are run . They are all different . What I want to emphasize in our CC is that whatever tier you are . That you feel comfortable here , part of a team of players that come here to find conditions that enable them to improve their game , hone their skills , lower their scores ,lower their averages , move up in tiers . Enjoyably and comfortably with the conditions that challenge them enough to keep that drive without the frustrationsof regular game play . All that is completely possible by either creating those tourneys yourself or by messaging me about it . Or someone else in your tier that has been creating tourneys . Any kind of information that you need to know should be provided here , any kind of appp , calculator , help , tutorial , tournament , statistic , message , opinion , gripe , compliment , etc , etc . Should able to be aqcuired here ( or in our website , as it may be easier there ). With your help , all of this can be done easily . We already have a good start . I am going to be here for a very long time trying to achieve all this . For any of you that think it's a good direction for your CC to go in . Then lets keep on keepin on . Sincerely , Your Co team member PDB1 , Paul ( sitting here on a rare rainy day ) May the SUN always be with you
POST OF THE WEEK

Re: Where are the Flags ?By Bertasion in Valley of the Sun Casual Club The other day upon the heather fair I hit a flagstick that was not there. I saw it's shadow and heard the clank but where it stood was just a blank. It was not there again today. I wonder when it will come back and stay. Brian

Li-Fi-like System Would Bring 100-Gbps Speeds Straight to Your Computer

subject title Li-Fi-like System Would Bring 100-Gbps Speeds Straight to Your Computer

Post by azdewars Sun Nov 29, 2015 10:35 pm

The light that zips data across the Internet’s backbone used to stop a long way from the data’s final destination. Now it goes all the way to your home. Why not go the last step and take the light all the way to the computer or TV, projecting it through the air over the last few meters and only converting it to an electronic signal at the end? Oxford University is doing just that with a system that takes light from the fiber, amplifies it, and beams it across a room to deliver data at more than 100 gigabits per second.
Such indoor optical wireless probably wouldn’t replace Wi-Fi, says Ariel Gomez, a Ph.D. student in photonics at Oxford University who describes the system in IEEE Photonics Technology Letters. But with a potential for data rates of 3 terabits per second and up, it could certainly find its uses. Wi-Fi, by contrast, tops out at about 7 Gb/s. And with light, there’s no worry about sticking to a limited set of radio frequencies. “If you’re in the optical window, you have virtually unlimited bandwidth and unlicensed spectrum,” Gomez says.

The trick, of course, is getting the light beam exactly where it needs to go. An optical fiber makes for a target that’s only 8 or 9 micrometers in diameter, after all. The team, which also included researchers from University College, London, accomplished this using so-called holographic beam steering at both the transmitter and receiver ends. These use an array of liquid crystals to create a programmable diffraction grating that reflects the light in the desired direction. The device is similar to that used in projectors, says
Dominic O’Brien, a photonics engineer at Oxford who directed the work.To accomplish this, they’d install a base station on the ceiling of a room, which would project the light toward the computer and also receive data heading out from the computer to the Internet.

It’s important to use transceivers with a wide field of view to make the alignment task easier, particularly because the device relies on wavelength division multiplexing, which splits the signal into slightly different colors of light. Like a prism, the diffraction grating of the beam steerer bends each wavelength a different amount. With a 60° field of view, the team was able to transmit six different wavelengths, each at 37.4 Gb/s, for an aggregate bandwidth of 224 Gb/s. With a 36° field of view, they managed only three channels, for 112 Gb/s.
The system requires a direct line of sight, and for now the receiver must be in a fixed position. The next step, O’Brien says, is to develop a tracking and location system so that a user could place a laptop at a random spot on a table and have the system find it and create a link.
Brien is a member of the Ultra-Parallel Visible Light Communications project, with colleagues at the Universities of Edinburgh, Strathclyde, St. Andrews, and Cambridge. One of their goals is to develop LiFi, which uses the light that’s also illuminating a room as a way to send data signals. He says LiFi usually refers to schemes based on visible wavelengths of light, whereas this system relies on infrared light at 1550 nm, which is used in telecommunications.
All these technologies—Wi-Fi, LiFi, optical wireless—may wind up being part of how people link devices to the Internet. “The world of communications is a world where everybody always wants more bandwidth”.

Like the song says " Let the Li Fi special shine it's ever loving light on you "

That song escapes me. OK ...never heard of it  : - ))  I've heard reference to "Gonna Hurt you where the light DONT shine. 
K thank you Paul for bringing out data for observation.
Might not see where I'm going with this, but we are going to smooth out some big wrinkles. You';ll see
