What are uplink power and downlink power? How does a cell signal
Uplink power is the strength of the signal transmitted by your phone or modem up to the cell tower. As the table above shows, a cell tower''s downlink power is 50 to 100 times or
The antenna output power level is typically between 20 watts and a few hundred watts for an outdoor base station. Television transmitters, by comparison, have 10-1000 times higher output power than outdoor base stations. Antennas mounted indoors use very low power levels, typically around a few watts or less.
Some mobile providers use higher power Tx and have 50% fewer towers or twice the spacing in urban areas. define question in terms of dBm or dBuV or dBW ERP @distance or input W vs technology etc, regional specs. Cell towers only transmit around 10 watts usually. Sometimes up to 50 or so in urban areas.
Very simple: Your phone will need more power to reach a base station far away, and the power that the base station needs to reach your phone will always be adjusted so that your phone will have good reception (if possible!), but not more. Important takeaway: building more towers will actually reduce field strengths, for both up- and downlink.
In telecommunications, particularly in radio frequency engineering, signal strength is the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are measured in dB - millivolts per metre (dBmV/m).
