Q. What is the typical range for a client card?
A. The typical range for a client card depends on many factors. Among them are data rate
(bandwidth) desired, antenna type and cable length (where applicable), and the device that
sends and receives the transmission. In an optimal installation, the range can be up to 300
feet.

Q. Are the 340 and 350 Series products interoperable?
A. Yes. The major difference between the two product lines is the power of the radio. The
350 Series has the stronger radio at 100 milliwatts. In a mixed installation, the shorter range
of the 340 Series prevails. Both series operate only in the 802.11b frequency band.
