What is the maximum output power of a cellular transmitter?

What is the maximum output power of a cellular transmitter?

Although the FCC permits an effective radiated power (ERP) of up to 500 watts per channel (depending on the tower height), the majority of cellular or PCS cell sites in urban and suburban areas operate at an ERP of 100 watts per channel or less.

What is the maximum allowable output power in dBm and Watts for the 5 GHz band?

FCC Rules and Regulations

BAND Frequency (GHz) Maximum Output Power
UNII-2 Extended 5.47-5.725 200mW 23dBm or 11 dBm + 10 log B, where B is the 26 dB emission bandwidth in megahertz *5
UNII-3 (Upper) 5.725-5.825 1 watt 30dBm *6

What are the FCC 15 rules?

FCC Part 15 is a federal regulation that sets limitations on the amount of electromagnetic interference allowed from digital and electronic devices such as wristwatches, musical instruments, computers, telephones, and low power transmitters.

What is the maximum transmit power for 802.11 b?

2.4 GHz. There exists two EIRP power limits for the 2.4 GHz band, one for 802.11b rates with CCK modulation (1, 2, 5.5 and 11 Mbps) and one for 802.11g/n rates with OFDM modulation. The limit is set to 20 dBm (100 mW) for OFDM and 18 dBm (63 mW) for CCK.

Is 2.4 GHz licensed?

The lower segment of the 24 GHz band (24.25–24.45 GHz) will be licensed as two 100-megahertz blocks, while the upper segment (24.75–25.25 GHz) will be licensed as five 100-megahertz blocks, with four 100-megahertz blocks and one 75-megahertz block offered in one PEA and only four blocks in three other PEAs.

What are FCC standards?

The term Federal Communications Commission (FCC) refers to an independent U.S. government agency that oversees all interstate and international communications. The FCC maintains standards and consistency among types of media and methods of communication while protecting the interests of consumers and businesses.

What is dBm transmit power?

dBm. dBm is an abbreviation for decibel relative to one milliwatt. It is a unit of level used to indicate that a power ratio is expressed in decibels (dB) with reference to one milliwatt (mW).

What is the maximum output power?

The power output in any electrical system is the product of output voltage, output current, and power factor (pf) as shown in equation 1 (below). Let’s use a DC circuit as an example: the maximum power output in a DC circuit corresponds to maximum voltage and maximum current, as pf is equal to unity.

What is the max output?

1 the greatest possible amount, degree, etc. 2 the highest value of a variable quantity.

What is the FCC limit on EIRP for a point to multipoint link?

53 dBm
If your equipment is used in a fixed point-to-point link, there are two exceptions to the maximum EIRP rule above: In the 5.8 GHz band the rule is less restrictive. The maximum EIRP allowed is 53 dBm (30 dBm plus 23 dBi of antenna gain).

What is FCC ERP?

Many FCC rule parts specify power and/or emission limits in terms of the transmitter system (transmitter, radiating antenna, and cable connector) effective radiated power (ERP) or equivalent (or effective) isotropically radiated power (EIRP).
