Cisco Aironet Series 2700/3700 Access Points Deployment Guide
Cisco Aironet Series 3700 Access Point
The DAS vendor and/or systems integrator is solely responsible for the support of the DAS products.
The DAS vendor and/or systems integrator also provides adequate RF coverage and supports any RF
related issues. This support includes, but is not exclusive to location accuracy, RF coverage, roaming
issues related to RF, multipath issues, and scalability.
Additionally, the DAS vendor and/or systems integrator is responsible for understanding that the
deployed DAS system meets the requirements of all of the customer's Wi-Fi devices and applications
over the DAS system; this statement includes, but is not exclusive to, all Voice over WLAN (VoWLAN)
and medical devices.
While Cisco Technical Assistance Center (TAC) and Cisco field teams do not provide support for RF
issues that arise in a Cisco WLAN used over a DAS, they provide support for non-RF related issues in
Cisco products as per the customer's support agreement with Cisco Systems.

Installations Inside and Around Elevators
Elevator coverage can sometimes be accomplished by placing APs in the near field of an elevator,
typically on each floor near the elevator door. Because elevators often have metal doors and the shafts
are often concrete or contain other materials that degrade Wi-Fi coverage, it is important to check the
coverage inside the elevator. While such coverage can be challenging it is often do-able, especially if the
elevator is only a few floors.
High rise elevators are more challenging because roaming issues are problematic; the client is cycling
through a large number of APs rather quickly. Some companies that do in-elevator advertising put a
patch antenna on the floor inside the shaft and a patch antenna on the bottom of the elevator car, while
other companies use leaky coaxial cable running on the side of the shaft.
When installing any Wi-Fi equipment inside the elevator cars or shafts, local regulations need to be
followed because many times such installations are prohibited either for safety reasons or because the
building owner or local fire department may prohibit the same. Also, it is dangerous and only elevator
repair persons or contractors who have experience with this kind of work should be in those areas.
