Router power consumption
 

Is the signal strength of a router depends on the router's power consumption?
To compare a router that uses 3.3V and one that uses 12V. Does this mean
that the 12V one can give stronger signal and support more wireless clients?

Tks.

Re: Router power consumption
 

Hi
The DC power supply voltage has noting to do with the RF output.
The RF output is rated in mW (milliWatts). The typical RF output of almost
all the Entry Level Wireless Devices is about 33mW regardless of their power
supply rating.
There are more expensive devices that are rated as High Power, and provide
up to 100mW.
Number of clients has to do more with the Bandwidth than the power.
May be this can further help.

Hello

So it is okay to attach a 5dBi antenna to this router that uses 3.3V?
Would the router able to support it since it is using such low power
consumption?
I need to confirm this with the experts.

Tks.

Hi
Yeah, it very good idea to attach better Antenna.
3.3V is the voltage Not the power. The power is W = I X V (Watt= 1A x
1Volt).
An electrical device that uses 3.3V and source 1 A provides Power of
3.3Watts.
An electrical device that uses 6.6V and source .5 A provides Power of
3.3Watts.
I.e. Different Voltage, but both devices provide the same power. The choice
of the Voltage is a design choice and Not a direct issue of Power.

RF output power does not change with the antenna. That antenna
would direct more power in one direction - less power in another
direction.

Re: Router power consumption
 

Output power is regulated by the FCC in the US. I'm sure there are other
"entities" that regulate them in other countries.

The "gain" of an antenna is the ability of the antenna itself to improve
efficiency all by itself with the existing power it is already given.
Yes,..you can use the antenna, but as some others have mentioned it may be
"directional".
