What is the purpose of EIRP and ERP in wireless communication ?
Following points mention purpose of EIRP and ERP in RF/wireless communication.
➨The radio transmitting devices should not exceed the limit set by regulatories bodies such as FCC and ETSI
for EIRP/ERP.
➨ EIRP = Transmit power + Antenna Gain - Cable Loss
➨ More EIRP refers to more transmit power.
➨ As we know higher transmit power is injurious to the health of the human beings.
It has been decided to limit it to avoid any harm and at the same time serve the purpose of communication.
➨Cell phone radiation and cell tower radiation with higher EIRP beyond limits
set by regulatory bodies will lead to following harmful effects.
• Various diseases in plants, insects, animals, birds etc.
• Effect on output of farm animals.
• Will cause following problems such as
headache, loss of sleep, fatigue, depression, memory loss,
ringing ears, cancers and so on to humans.
The main purpose of limiting EIRP and ERP is to avoid all the above problems. Refer best ways for Cell phone radiation protection >>.
EIRP and transmit power limits set for LoRaWAN technology in INDIA are mentioned in the table above.
