Hi
I want to know that we can calculate the energy efficiency (EE) in the wireless networks. Several paper define it as bits/Joule. But in some cases, EE is greater than 1.
Let's suppose:
The normalized throughput at the destination is 2.5 bits/s/h. The transmit power is 1 watt (30dBm) and the circuit power is 0.003162 Watt (5dBm). In this case the EE can be expressed as:
EE=2.5/1.003162 that is equal 2.49 which does not make sense because efficiency is always less than or equal to 1.
