Freedom without Order is a Sure Path to Chaos
Maximizing spectrum efficiency is a challenge that operators have wrestled with for decades. And the challenge of optimizing spectrum planning and management is only magnified as networks become faster and more complex. Operators with a well thought-out plan can avoid significant waste and inefficiency in the network. Wavelength division multiplexing was originally constrained to a fixed grid, first at channel widths of 100GHz, and then, as lasers improved, at 50GHz.
