Wireless and wired

At the F2C conference of David Isenberg the classical debate of wireless versus wired has been restarted. In my opinion they are symbiotic.

Look at the simple Baken mobi-law: D x B x Q = Constant, 

D = Distance

B = Bandwidth

Q = QoS

And so if d = Ln D, b = Ln B,  q = Ln Q then d + b + q = c with  c = Ln C => (dbq,e) = c with dbq the vector (d,b,q) and e the unity vector 3^-1/2(1,1,1), normal to the plane of “constant mobility” where you have to compromise between D, B and Q. The constant c will improve, increase with time and technology developments, but will never be large enough to ensure our bandwidth hunger in larger 3G, 4G LTE cells and has a physical ceiling … so … there is only one conclusion!! The cell diameter has to become smaller and smaller … thus one inevitably comes to microcell generated by antennas on/in all our street furniture … and yes Streetlights (we have over 4.000.000 in the Netherlands! In cities and … all along our highways!), VDSL cabinets or bus stop (cabinets). In 1999 I said, since people and cars do not want fibres attached to them:

The more broadband applications, the more (mobile)broadband bandwidth, the smaller the cells, the higher the frequencies … in the end we will have “ether over fibre”.
