Yes, generally they are.
the communication satellites take 24 hours to complete their one revolution around the earthso the orbit of revolving satellite is called geostationary orbit.
It is used for communication plates where geostationary satellites can't reach, in polar areas. Russia uses elliptical satellites where the geostationary satellites can't reach.

Geostationary satellites.Geostationary satellites.
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
Geo-stationary communication satellites are 35,768 Km far from earth surface at an equatorial latitiude.
It depends on which satellite you are talking about. However YES, it is closer than any geostationary weather satellite and it is closer than any GPS satellites.
That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.
Geostationary Earth-Orbiting Weather Satellites
Geostationary satellites, those which orbit at the same speed as the Earth remain fixed over an area of the planet. This allows them to be used as camera platforms to show the motion of the weather patterns relative to an area of the Earth as seen by the satellite.
Orbiting the Earth above the equator is true of geostationary weather satellites and they have infrared sensors to transmit images of the entire hemisphere continuously. All of those things are true except that while they are moving in orbit they appear motionless.
