Co-location in an Extended Service Set
- Multiple access points with overlapping coverage areas is called colocation, and the intended goal is increased client capacity as opposed to roaming.
- Colocation is one method of providing coverage for a high density of client devices in the same area.
Co-location in a Single Channel Architecture (SCA)
- Co-location design in singlechannel architecture is often referred to as channel stacking.
- Each layer of multiple APs on a single channel and using the same virtual
BSSID is known as a channel blanket or channel span. - Although this might sound like a good idea in theory, most customers are not
willing to pay for three co-located access points everywhere coverage is needed. - Another possible disadvantage with an SCA architecture is that the contention domain is very large.
- Although AP transmissions are coordinated by an SCA controller to minimize collisions with other APs, SCA technology is highly proprietary and there is no guarantee that client transmissions can be controlled to perfection.
