General conclusion The result of the verified test areas, such as
authentication, association, handover and call stability test,
produced in very good results. The roaming times, both PSK and
802.1x were excellent by ranging in the interval 30 to 70m.
Performance has also been proven to be very good. In both active
and U-APSD mode it was possible to keep up 12 simultaneously calls
per AP one single access point. Keep in mind that the limitation
was available handsets and not system capacity. Consider the below
mentioned caveats.
Known issues
• Roaming with AP330/350. It was noticed that the key exchange
failed at a few roaming
occasions both when using PSK and .1X authentication resulting in a
few seconds speech gap. Frequency approximately 1 out of 80
roaming. Impact: Minor due to low frequency and symptom Workaround:
None Refer to Ascom Ticket 22235 for details.
• Opportunistic Key Caching (OKC) not always working with
AP120/121.
Impact: Moderate. Workaround: Use PSK authentication instead. It is
our recommendation to avoid usage of 802.1X authentication with the
AP120/121 until this is resolved. Aerohive has indicated that this
is a bug which will be fixed in an upcoming release. Note that
Ap330/350 does not experience this problem. Refer to Aerohive
ticket 24913 or Ascom Ticket 22236 for details.

ASCII format. Example shows a key entered in ASCII format.

Proactive PMK ID response is checked.
WPA2 802.1X (Enterprise) – RADIUS configuration

“secret” that corresponds to the secret configured in the Radius
server.

Data rate configuration. (Same for all encryption methods)
- To improve the performance in the wireless system it is
recommended to disable the lowest data rates.
Interoperability Report - Ascom i62 / Aerohive Networks 12
2013-08-13
Advanced SSID settings (Same for all encryption methods)
- Set the DTIM settings to 5. DTIM value 5 is recommended in order
to allow maximum battery conservation without impacting the
quality. A lower value is possible but will negatively impact the
standby time.
- Make sure Enable WMM is checked. - Make sure Enable Unscheduled
Automatic Power Save Delivery is checked. U-APSD is not
mandatory but is highly recommended as it will significantly
increase the talk time.

Radio Configuration
Radio Profiles. (5Ghz)
- Example shows the default profile radio_na0 - Channel with is set
to 20Mhz but 40Mhz has also been verified. - Make sure the beacon
period is set to 100TU

2013-08-13
Radio Profiles. (2.4Ghz)
- Example shows the default profile radio_ng0 - Channel with is set
to 20Mhz. 40Mhz channel width is not recommended on the 2.4Ghz
band. - Make sure the beacon period is set to 100TU
Interoperability Report - Ascom i62 / Aerohive Networks 18
2013-08-13
Configuration of access points
- Radio profiles used is the default (radio_na0 and radio_ng0). See
earlier steps for configuration of the radio profiles.
- In the example channel has been set manually for each access
point. Note. 1. Enabling more than 8 channels will degrade roaming
performance. Ascom strongly recommends against going above this
limit. 2. Using 40 MHz channels (or “channel-bonding”) will reduce
the number of non-DFS* channels to two in ETSI regions (Europe). In
FCC regions (North America), 40MHz is a more viable option because
of the availability of additional non-DFS channels. The handset can
co-exist with 40MHz stations in the same ESS. 3. Make sure that all
non-DFS channel are taken before resorting to DFS channels. The
handset can cope in mixed non-DFS and DFS environments; however,
due to “unpredictability” introduced by radar detection protocols,
voice quality may become distorted and roaming delayed. Hence Ascom
recommends avoiding the use of DFS channels in VoWIFI deployments.

Ascom i62 Network configurations (WPA2-PSK)
- Set IP DSCP for voice to 0x30 (48) – CS6 to match default
mappings in the Aerohive system.

i62 network settings for 802.1X authentication
(PEAP-MSCHAPv2)
- Set IP DSCP for voice to 0x30 (48) – CS6 to match default
mappings in the Aerohive system.
If 802.1X Authentication is used a root certificate has to be
uploaded to the phone by “right clicking” - > Edit certificates.
Note that both a root and a client certificate are needed for TLS.
Otherwise only a root certificate is needed. Server certificate
validation can be overridden in version 4.1.12 and above per
handset setting (Validate server certificate).

Innovaphone IP6000 (IP PBX) The Innovaphone IP6000 was configured
with a static IP address of 172.20.106.113. Signaling is less
relevant here since testing homes in on interoperability in
relation to the WLAN infrastructure and not features of the IP PBX.
IP6000 configuration: See attached file
(complete-IP6000-08-03-a6.txt) for configuration.
