Hello Cisco WLAN experts,
this big hospital has invested already in additional Cisco-WLAN-APs which shall be placed in addition to existing WLAN APs
to offer a powerful and redundant "Medical Grade WLAN" to our patients and clinical personnel.
We would like to use Apple IPhones for Skype WLAN Voice telephony and would like to use
Apple IPads for a new electronic Patient Information to allow doctors to show live Videos for example.
But the new Finance Chief Officer is not convinced about our nice strategy and is demanding a Site Survey on beforehand
and after a small test Installation before allowing further Investments into a big rollout.
Therefore I need some recommendations how to "tune" the existing Cisco-WLAN-AP-installation to show the right results
afterwards, that will free the money for the implementation finally.
Does it make sense to statically configure TX Power Level on the WLC during the Site Survey ?
To which Power Level should I adapt the sending power in 2.4- and 5 GHz-Band ?
FIXED to 1 (100mw), 2 (50mw), or 3 (25mw) ?
I haven't found any info about the TX Power Levels of Apple-devices by the way.
I would assume that I have to use an identical or lower TX-value on the APs.
Is there anybody out there who knows these details ?
Thank You for Your tipps
Hello Leo and Scott,
thank You very much for Your comments.
What do You mean with POC ? POC= Proof Of Concept or Plan Of Correction ?
In parts of the Hospital, WLAN Phones from Unify Siemens, a copy of a Ascom WLAN Phone, are in place with 23dBm.
Only useable on 2,4GHz with the existing small number of WLAN APs. On 5GHz roaming problems occur.
Target is to migrate to 5 GHz and use Apple devices for Voice for example Skype for Business.
A site Survey done 2 years before by externals came out with the result to increase the numbers of WLAN APs by factor 2.5
to accomplish this target.
In general, shall we statically fix the TX-Power during the Post-Survey ?
If Yes, to which value for voice-WLAN-coverage in 5 GHz ?
Also a question to the result of a passive Site Survey, which I have never done yet.
For example the Ekahau tool.
Is is possible to simulate the results afterward within that tools?
Let's assume, the Post Site Survey has been done using existing Cisco WLAN APs at Power Level 1 or the Level just calculated by RRM.
Is it then possible to simulate the results of the Site Survey using only 50% of the TX-Power or only 25% of the original to show the outcome ?
(Compareable to Cisco Prime Map, where I can simulate different heatmap coverages by choosing a different RSSI cutoff value)
Thank You for Your comments
