Your question is too broad.
Here's my answer.
WIRES.
GSM900 transmitted power from BTS: 39dBm GSM1800 transmitted power from BTS: 36dBm
ratio of transmitted power and received power
R is proportional to 1/4th power of transmitted power so answer is 2
Total Power = Power of unmodulated carrier + 2 * Power per sideband
Power over ethernet (PoE)
Because AC allows the power to be transmitted over distance at high voltage and then transformed down for the users.
In solar power plants, the power is directly transmitted through converter but excess power is usually stored in a battery and transferred through converter.
trougth wires
transmitted power and channel bandwidth
Your question is too broad. Here's my answer. WIRES.
By converting it to microwaves
In 2wd it will free wheel while driving. There is no power being transmitted through it though.In 2wd it will free wheel while driving. There is no power being transmitted through it though.
