Client Roaming in a Micro and Macro Cell
RF Operations on "E/P" Series Access Points
The smart RF antenna connector sometimes referred to as a DART carries the digital signals (18 mins) as
well as the four analog RF ports from the XOR radio.
The term DART is an Amphenol trademark name for this type of connector.
Note
Unlike the internal models, the smart connector allows both antenna systems to be located away from each
other enabling deployments that cannot be done with the internal model. For example, the creation of two
5–GHz Macro cells is not possible in addition to separating the 5–GHz cells into different areas (think
inside/outside) or different coverage areas in a factory or stadium.
Sometimes unique customer requirements dictate that 2.4–GHz RF operation be on one set of antennas and
5 GHz on a completely different set of antennas, and that is also possible.

Since both sets of antennae can be physically spaced apart, many new RF design opportunities become available
allowing for many different types of new and unique installations.
Some deployment options include:
1 Omni and directional deployments (think hospital room and a long hallway) with one AP
2 Any combination of Micro and Macro cell deployments
3 Using stadium antennas, two different 5–GHz coverage cells can be done with 1 AP
