3 1. Einleitung Im Muster Krankenhaus soll eine WLAN Ausleuchtung durchgeführt werden. Folgende Anforderungen werden an das zukünftige WLAN gestellt: - WLAN-Technologie 54Mbit (802.11a/g) - Festlegung von Messpunkten, welche die gewünschte WLAN-Abdeckung beschreiben - Definition von Schwellwerten für die Performance sowie die gewünschte Redundanz - Vermessung der Kankenhausbereiche zur Lokalisierung der optimalen/möglichen Standorte der Access Points. - Dokumentation der AP-Standorte in maßstabsgerechte Grundrisspläne. Die zu erzielende Bandbreite zur Definition der Accesspoint Anzahl soll nach Vorgabe des Muster Krankenhaus Musterstadt, soweit möglich, bei ca % der möglichen Bandbreite 54Mbps liegen. Die Ebenen EG und 4. OG des Hauptgebäudes des Musterkrankenhauses sollen bei der Ausleuchtung nicht berücksichtigt werden. Bericht vom: 0*.0*.200* Seite 3 von 27

4 2. Ergebnisse in grafischer Auswertung Diese WLAN Ausleuchtung wurde mit dem unter Punkt 3 beschriebenen Messequipment und dem Surveyor Tool AirMagnet durchgeführt. Da sich die Messergebnisse durch Messungen mit unterschiedlichem Equipment unterscheiden können, sind für diese Ausleuchtung und das Ergebnis die unter Punkt 3 aufgeführten Komponenten entscheidend. Messungen mit Komponenten anderer Hersteller, können zu einem anderen abweichenden Messergebnis führen. Die Ausleuchtung erfolgte während des normalen Betriebes. Störeinflüsse die ggf. außerhalb der Ausleuchtungsaktivitäten/Datenaufnahme aufgetreten sind, wurden grundsätzlich nicht erfasst. Sollte es nach den Ausleuchtungsaktivitäten/der Datenaufnahme zu baulichen/physikalischen/ funktechnischen/... Veränderungen kommen, kann dies zu einer Veränderung der Ausleuchtungsergebnisse führen und somit die aufgeführten Messergebnisse beeinflussen. Es ist also darauf zu achten, dass nach einer baulichen Maßnahme innerhalb der betroffenen Bereiche und vor der Implementierung eines WLANs in diesen Bereichen eine erneute WLAN Ausleuchtung stattfinden sollte, nur so ist ein störungsfreier Betrieb zu gewährleisten. Die Ergebnisse der Messungen (Übersicht der notwendigen Access-Points sowie Speed- Messergebnisse) werden auf den nächsten Seiten grafisch aufbereitet dargestellt. Sie basieren auf den Einsatz eines Access-Points sowie eines Notebook mit entsprechender WLAN-Adapterkarte. Bericht vom: 0*.0*.200* Seite 4 von 27
