6. WIRELESS NETWORKS IN HEALTHCARE ENVIRONMENTS Link-Up 10-13-2010

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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

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) Link-Up 10-13-2010

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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

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.” Oberon model 1052 with ZDUAL antennas Link-Up 10-13-2010

16. 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 Link-Up 10-13-2010

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 Link-Up 10-13-2010

18. CABLING FOR IEEE 802.11n AND 802.11ac WIRELESS ACCESS POINT Link-Up 10-13-2010

19. CABLING FOR FUTURE WIRELESS NETWORKS 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 • >1 Gb/s rate (MAC layer throughput) • 60 GHz bands • In room coverage only Link-Up 10-13-2010
