WIRELESS NETWORKS IN HEALTHCARE ENVIRONMENTS
7

• Healthcare Wi-Fi and DAS
• - Hospitals were early adopters of wireless
  networking
• In hospitals, wireless networking is mission
  critical, serving point of care (bedside)
  applications, mobile workstations on carts, EHR,
  mobile asset tracking, RFID, telemetry, voice
  over Wi-Fi, etc.
• Hospitals have special requirements that are
  becoming more widely adopted
• Infection Control Risk Assessment (ICRA)
• Strict adherence to codes and standards (NEC and
  TIA)
• Physical Security
• Suitability for Psychiatric facilities
• Preservation of the design for mandated
  performance
• Aesthetics

8
Infection Control Risk Assessment (ICRA)

• In Healthcare, the Joint Commission on
  Accreditation of Healthcare Organizations (JCAHO)
  requires that hospitals establish procedures for
  mitigating the spread of infectious disease and
  contaminants.
• ICRA procedures limit access to the space above
  suspended ceilings (where dust and spores have
  accumulated)
• Infection Control Risk Assessment (ICRA) could
  have a serious impact on the times and conditions
  for cabling installation, moves, adds and
  changes, particularly in the plenum space,
  above suspended ceilings, or in walls
• Breaches in the ceiling system should be avoided
• Contractors performing work in violation of ICRA
  procedures will be precluded from future bidding

9
Infection Control

• It is desirable to eliminate gaps and mouse-holes
  in ceiling tiles to
• Reduce the spread of dust and spores
• Maintain desired differential pressure
  relationships
• Preserve the fire rating integrity of the ceiling
  system

10
Infection Control

• Lifting or removing ceiling tiles requires the
  installer to
• Use Negative Air Pressure Enclosure (NAPE), or
  tent off the work area
• Use a HEPA air filter

11
Infection Control
Oberon model 1059-00

• Ceiling enclosure can help to
• Eliminate gaps and mouse-holes in the ceiling
• Simplify ICRA procedure compliance
• Simplify maintenance

12
TIA-1179 Healthcare FacilityTelecommunications
Cabling Standard

• Recognizes that adding or changing horizontal
  cabling may cause disruption to occupants and
  their work once the buildings ceiling and walls
  are closed
• Adding or changing horizontal cabling could
  result in a net decrease in care being provide,
  jeopardizing infection control measures.
• Advocates use of enclosed pathways in
  air-handling spaces to avoid disruption of
  operations
• Advocates planning well ahead in cabling design
  and capacity
• Telecommunications enclosures (TEs) are an option
  in areas subject to infection control measures
• TRs and TEs should incorporate additional
  security measures to restrict access (Workgroup
  switches and APs)

13
BICSI 004-2012 Information Technology Systems
Design and Implementation Best Practices for
Healthcare Institutions and Facilities

• Regarding DAS design
• Shall support requirements of Clinical
  Engineering, Information technology department,
  and facilities department
• Shall support requirements of cellular service
  provider, public service radio, first responder
  radio and wireless medical telemetry systems
  (WMTS)
• Shall be authorized by the service provider
• Shall provide coverage which is ubiquitous and
  robust

14

• Code Compliance
• Hospitals are strict adherents to building
  safety codes and telecommunications standards
• - 2012 NFPA 99 Health Care Facilities Code
• Authorities Having Jurisdiction (AHJs) will
  require strict NFPA 70 N.E.C compliance and UL
  listing of installed components
• Burn ratings of ceiling systems must be retained
• Use products designed to satisfy National
  Electric Code (NEC) paragraphs 300.22 and 300.23
  for installation in the air-handling (plenum)
  space
• Use suitably UL listed products

15
N.E.C COMPLIANCE

• Article 300.22(C)(3) Electrical equipment with
  a metal enclosure, or electrical equipment with a
  nonmetallic enclosure listed for use within an
  air-handling space. shall be permitted to be
  installed in such other space unless prohibited
  elsewhere in this Code.

• Article 300.23 cables, race-ways and equipment
  installed behind panels, including suspended
  ceiling tiles, shall be arranged and secured so
  as to allow removal of panels and access to the
  equipment.

Physical Security of the installation may be
required for the purposes of

• Mandated Coverage some jurisdictions have
  enacted ordinances that include provisions for
  radio coverage of public safety signals within
  the building as a condition of occupancy
• HIPAA - Protection of confidential patient
  information
• Patient Safety Standards applied to psychiatric
  inpatient units

17
In a hospital, who is involved in the cabling and
wireless design?

• Telecom/datacom infrastructure- cabling and
  wireless personnel
• Plant Services or Facilities Personnel
• Infection Prevention and control coordinator or
  Infection Preventionist- in Quality Control or
  Patient Services Department
• Public safety/in-building comm coordinator
• Bio-Medical personnel

• IEEE 802.11n
• Multiple Tx and Rx antennas (MIMO)
• 200 Mb/s data rate (MAC layer throughput)
• 2.4 GHz (3 channels) and 5 GHz bands (21
  channels)
• IEEE 802.11ac
• Multi-User MIMO (greater capacity)
• 1 Gb/s rate (MAC layer throughput)
• 5 GHz bands only (21 channels)
• IEEE 802.11ad
• gt1 Gb/s rate (MAC layer throughput)
• 60 GHz bands

CABLING FOR FUTURE WIRELESS NETWORKS

• Design for 5 GHz (802.11ac) networks
• Higher density of APs, improved capacity, not
  coverage
• Coverage similar to 802.11n 5 GHz band
• Does not cover as well as 2.4 GHz
• Use all 21 channels
• Will require PoE Plus for full performance
• Avoid above ceiling mounted solutions
• And perhaps 60 GHz (802.11ad) networks
• Higher density of APs
• Use all channels
• Greater than 1 Gb/s MAC layer throughput to each
  AP
• In room coverage only, will not go through walls
