The Joint Commission, which is the body that accredits healthcare facilities, has specified that facilities should establish Infection Control Risk Assessment (ICRA) procedures for mitigating the spread of infectious disease and agents. Recognizing that the air-handling (plenum) space above a suspended ceiling may accumulate dust, the risk assessment procedure may control access to the to the air-handling (plenum) space above suspended ceilings.

 

If work is to be performed above the suspended ceiling, requiring that ceiling tiles are lifted or moved, it may be necessary to "tent-off" the work area using plastic sheets, or use a moveable Negative Air-Pressure Enclosure (NAPE). The tented area needs to ventilated and the air filtered by a HEPA filter. This process is time-consuming, and may be disruptive to work flow in the vicinity. Unfortunately, this space above or in the suspended ceiling is precisely where wireless access points are located, due to preferred wireless coverage from the ceiling location. Likewise, the supporting cabling for the wireless is located in this air-handling space.

Recognizing this, the TIA-1179 Healthcare Facility Telecommunications Infrastructure Standard states that "Adding or changing horizontal cabling could result in a net decrease in care being provided, jeopardizing infection control measures or compromising life safety measures".

Furthermore TIA-1179 indicates that "Infection control requirements (ICR) could have a serious impact on the times and conditions for cabling installation, moves, adds and changes, as well as restrictions to removing ceiling tiles, wall penetrations and access to unoccupied spaces".

Consideration of the expense of removing or even lifting ceiling tiles suggests that healthcare facilities people will carefully consider how wireless access points are installed and secured in healthcare facilities.

Wireless LAN access point ceiling mounted enclosures and mounting solutions offer a convenient means to install and secure the wireless infrastructure. Once the enclosure is installed within the ceiling gridwork, access points can be conveniently serviced and/or replaced, simply by unlocking and opening the enclosure door. Since the air-handling space is not breached, there is no need to "tent-off" the work area. This manifests itself as reduction in maintenance costs, and lessening of the impact on care being provided, both of which are objectives high on the priority list of facilities managers. The enclosure surfaces can also be easily wiped down.

Enclosures can simplify Infection Control Risk Assessment (ICRA) compliance. By moving the Wireless AP inside the enclosure, it can be accessed without breaching the plenum space.

Secure, Convenient, aesthetic mounting solutions for virtually every vendors wireless access points. Interchangeable doors permit simple migration to new APs, antennas and technologies.

TIA 1179 also states that "Telecommunications Enclosures (TEs) providing support for life and safety networks should incorporate additional security measures to restrict unauthorized access to the space". Workspace TEs and access point enclosures should be lockable, providing that additional security measure specified.

Finally, the standard recognizes "that many healthcare installations make use of a number of wireless applications. It is recommended that the wireless environment be characterized and understood prior to the design, choice, and installation of cabling to ensure satisfactory performance". Indicating that a site survey should be performed as part of the design, and interference sources should be identified. In order to preserve the integrity of the site survey, access points and antennas should be secured so that they are not accidentally or intentionally moved or disconnected.

Oberon’s line of wireless access point enclosures and mounting solutions provide a means to simplify ICRA procedure compliance. With the AP mounted in the enclosure or mount, the AP can be accessed without breaching the air handling space above the suspended ceiling. Oberon’s line offers a solution for securing most vendors APs, including those with internal and external antennas. Oberon’s products are UL listed and designed for installation in the air-handling space. The back box is solid (not ventilated), thereby preserving the integrity of the ceiling system. The doors on Oberon’s enclosures are interchangeable, permitting upgrades and migrations to new APs, antennas, and technologies, again, without getting into the air-handling space.
