Q: What is the
difference between the integrated WSM BLE and all Clean Air APs with 8.0?
A: The WSM module can
also be a BLE beacon and send out BLE energy. With ClearAir, we detected BLE.
In MSE 10.0, you get BLE awareness (detect BLE devices) using CleanAir APs.
BLE radio integrated
into the WSM is a full Tx/Rx radio that allows BLE to act as a beacon, and also
allows you to use the BLE radio in the WSM to configure other beacons in future
Q: Can the AP be
placed either vertically or horizontally and still provide this accuracy?
Hyperlocation circular array antenna requires ceiling mount or optional “wedge”
type wall mount from third party companies such as
http://www.oberonwireless.com/ additionally optional
external antennas provide horizontal flexibility.
Q: Will the
Hyperlocation module support CleanAir, as the WSSI does today?
A: The Hyperlocation
solution consists of two items such as an active antenna array and a new
Wireless Security Module (WSM). WSM is the new name for WSSI, and it supports
all the same features but has an 11ac radio for 20/40/80 MHz bandwidths.
Q: Will HyperLocation
work in both 3600 and 3700?
A: Of course that is
the value of a modular based architecture and this is how Cisco can deliver
emerging technologies like BLE and location to existing AP platforms.
Q: Will these modules
A: Hyperlocation and
WSM through the antenna array is a listen only mode. The module has an 11ac
chipset but not for client data. Data is handled through the AP's integrated
antennas. MU-MIMO is an 11ac Wave-2 function, so it is not supported at this
Q: Will new external
antenna array have a Plenum rating?
A: Integrated “ring”
antenna is not Plenum as designed to remain below the Plenum airspace. External
antennas are under development and likely to be Plenum but that has not been
fully determined yet.
Q: When one
Hyperlocation is present and other APs are non Hyperlocation, does only the
Hyperlocation information used for location? meaning, Probes and RSSI are not
A: No. All data is
used but Hyperlocation Angle of Arrival (AoA) data is obviously weighed heavier
when making location assessments. When both RSSI and AoA are collected and sent
to the MSE, we refer to that feature as “fusion”.
Q: Can I perform
location with a single Hyperlocation device?
Q: If a connected
client is attached to a non-hyperlocation AP, are the other APs that have
Hyperlocation still able to hear and track the client making AoA assessments?
A: Yes. For example,
AP #1 is aware of the other Hyperlocation APs on different channels and can
schedule those APs to have their WSM modules to go off channel to monitor AP
#1’s channel to capture location information on its behalf. This information
along with RSSI from AP1 are all weighed in the location assessment.
Q: Can the WSM and
Hyperlocation module do location based services and wIPS at the same time?
A: Yes. The WSM module
is a newer version of the WSM (formally WSSI) module. Once the antenna array is
connected to the WSM module, it will support both.
Q: What is the optimal
placement for Hyperlocation accuracy?
A: For best
performance, you should have a few Access Points that are in line of sight of
the device and less then than 70 feet away. While Hyperlocation will work with
only 1 AP (greater accuracy) occurs when 3 or more are used.
Q: What methods are
used to show the improved accuracy?
A:The CMX 10.2 shows
the updated location more quickly on the map and with a higher degree of
accuracy. There is no visual indication that a device was located via
Hyperlocation vs using the traditional location method. The location accuracy
test should show that the location is calculated more frequently and with a
higher degree of accuracy.
Q: Is there any
change in the Location API?
A: There is no change
in the location API. There is no indication in the API if the device was
located using Hyperlocation or traditional location methods.
Q: Packet detection
RSSI minimum—This looks to default to –100 db. In our retail environment, which
is approximately 4000 square feet, with nine APs approximately 25 – 30 apart,
should we reduce this to the –75 range?
A: 4000 square feet
APs separation with -75 will help location accuracy.
Q: What is the impact
of sliding the min RSSI on both resources (AP, WLC,CMX 10.2) and location
A: This will help the
location accuracy and roaming by only allowing stronger signals to be part of
the location solution.
Q: Scan count
threshold for idle client detection—What specifically does this mean, how are
we defining an idle client?
A: Every client idle
timeout is different, for example; iPhone and android has its own settings.
When a client is not sending data for X scan periods it is considered idle and
the Hyperlocation module schedule the primary radio to send a packet to wake
the device so it can be located.
Q. What applications
can we use to test BLE functionality?
A. Radius Networks
Locate iBeacons App, Cisco provided App, Phunware application.
Q. Can we combine Non
HyperLocation and HyperLocation AP’s together on the same floor map?
A. Not in this
release, all of the devices that are on a specific floor should be either
HyperLocation or Non HyperLocation APs.
Q. My AP is showing
the IP address of the MSE as 127.0.0.1 ?
A. This will likely be
fixed by FCS, but this was a problem that occurred when the HOSTNAME file is
incorrectly set on the CMX 10.2 instance. Please check that the /etc/hosts file
has an IP address assigned to the local host.
Q. I’m getting a “disk
space is full” how do I clear it before upgrading to a later version of CMX?
A. Remove all of the
old versions of code from /home/cmxadmin. Remove all of the old versions of
logs from /opt/cmx/srv/var/logs/ (all files more then 1 month old)
Q. I know probing
clients are not tracked via AoA – Can we use AoA for a client that is
associated, but not authenticated (not in RUN state). For example, typical
guest WLAN with a WebAuth configuration, client has IP, client is associated to
AP but client is not in run state, but in WebAuth state until they accept an
AUP or login with credentials.
A. Yes this should
Q. I am enquiring
about an opportunity for Hyperlocation in a warehouse environment to track tags
which are placed onto static vehicles. Will Hyperlocation support active RFID
A. While the
Hyperlocation unit is hardware capable, this is a feature being considered for
subsequent releases, and is more likely to be done with ACTIVE ASSOCIATED RFID
Q: Is there a height
requirement for AP, i.e. for a warehouse environment should we attempt to keep
it below 10ft?
A: No requirement to
keep to 10 Ft or below, higher ceilings also work.
Q: For some reason I’m
still unable to get the MSE IP to show up on the AP which I’m assuming is why
hyper location isn’t working for me. I’ve rebooted the controller and the HALO
AP a couple times, toggled hyper location on/off under the global settings on
the controller a couple times and toggled the module itself on/off a couple
times. Normal RSSI location is working
A: Disabling and
Enabling HyperLocation on the WLC is one way to get the AP to relearn the IP
address of the MSE.Another method would be to delete the WLC from the MSE and
add it back.This works best if you have SNMPv2 enabled on the WLC.
Q: Does Hyperlocation
require the exact location, elevation and orientation of the AP to be entered
A: Yes, in this
release that is how it works, much like a “laser pointer” you need to be
precise in knowing where you are before you can know where something else (like
a client) is with precision. We are working on making this easier in subsequent
Q: How do you enable
A: This is done in the
MSE WLC GUI screen
Q: It is possible to
deploy by separating the room into different groups so I can see the difference
between simple RSSI location and RSSI + Hyperlocation (AoA)?
A: Yes you can create
two maps. One that has Hyperlocation and one that does not and then switch
between the two maps.
Q: Does the
Hyperlocation with advanced security module RM3010L use Probe RSSI or Data
A: RM3010L only helps
with Data packet RSSI. It does not participate in Probe packet location
Q: I understand
Hyperlocation module does not currently track BLE beacons (only associated
clients) but uses Cisco’s Clean Air to track and display beacons based on RSSI.
Do you know what version of code CleanAir supports this?
A: Minimum version for
BLE detection is WLC 8.0MR1 and does not require the Hyperlocation module, this
works with ANY Cisco CleanAir enabled Access Point.
Q: Can I use an
earlier version of Prime (prior to 3.0) for Hyperlocation?
A: No – Prime 3.0 has
an azimuth feature to correctly orientate the Hyperlocation antenna array.
Q: A customer is
looking to use Advanced WIPS and CMX Guest. Given that CMX 10.x doesn’t yet
support WIPS is there any issue with running CMX 10.2 Base and Advanced, and a
second VM with MSE 8.0 with aWIPS licenses?
A: Yes they can run
both CMX 10.x for guest and MSE 8.0 for WIPS.
Q: When using CMX 10.1
for BLE beacons tracking, is there any limit on the maximum number of beacons
that can be tracked? Would it be also depending on the capacity of the WLC?
A: BLE Beacons use up
CLEANAIR slots on an AP. The maximum number of BLE is the same as the max
number of interferers.
Q: How does a single
Hyperlocation know, how far away the client is ?
A: The angle or 30
degree pitch area is used primarily when only 1 AP is present, and reasonable
assessments are done based on RSSI and AoA of course the more Hyperlocation
units the better for accuracy.
Q: How much weight
does the Hyperlocation antenna + WSM module add to the AP?
A: Module is 0.3 kg.
Ant. 1.1 kg.
works for associated clients only correct? Is there capability in CMX 10.2 to
see both probing/associated clients?
A: Yes for
unassociated, you get your traditional RSSI accuracy.
Q: How many UUIDs can
the BLE beacon on the hyperlocation module broadcast at one time?
A: We can have up to
5x UUID each with a different power level.
Q: Are CMX and MSE
A: MSE is the actual
hardware/engine, CMX is the solution name
Q: What is the
recommended distance to place Hyperlocation Access Points ?
A: Standard 1 in 2500
Square Feet or approximately 40-50 Ft apart
Q: Is there an in-tile
mount or a wall “wedge” type mount for the Hyperlocation solution?
A: We are working with
3rd party companies who will be offering same.
