6 General conclusion The result of the verified test areas, such as authentication, association, handover and call stability test, showed very good findings. Some settings are required to ensure good voice quality on 5 GHz with WAC6500 series. The roaming times, on open, PSK and 802.1x MS-CHAPv2 were adequate and were in the range between 25ms to 70ms. The exception to this was the WAC5302 in combination with 802.1x MS- CHAPv2. Roaming times found were around 250ms, consistently, which indicate that OKC is not working properly. However loss of connection did not occur. It is strongly advised to keep roaming times below 150 ms. A number of settings are required to set in the ZyXEL Controller and i62 handset in order to get the best performance out of the handset. It is highly recommended to use QoS for the most optimal speech quality when in call. U-APSD/WMM is required for the most optimal battery usage. Without this setting the battery will drain rapidly! U-APSD is disabled by default in the system and must be enabled through the CLI on the Zyxel controller. The recommended setting for DTIM is 5. The tested battery lifetime on standby is around 80 hours. Keeping the DTIM to 1 (system default) will half the active standby and active call time. Note that the age of the battery in the handset has a great impact on battery life expectancy. An older battery will have less battery lifetime then a fresh one. It is recommended to follow the best practice of Ascom in regards to channel planning and channel bonding, as shown below: General guidelines when deploying Ascom i62 handsets in a/n/ac environments: 1. Enabling more than 8 channels will degrade roaming performance. Ascom 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), 40 MHz is a more viable option because of the availability of additional non-dfs channels. The handset can co-exist with 40 MHz stations in the same ESS. 3. Ascom do support and can coexist in 80MHz channel bonding environments. The recommendations is however to avoid 80MHz channel bonding as it severely reduces the number of available non overlapping channels. 4. 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 if possible avoiding the use of DFS channels in VoWIFI deployments. *) Dynamic Frequency Selection (radar detection) It is highly recommended to deploy the VoWLAN network to the 5 GHz frequency whenever possible, due to non-overlapping channels and less chance of non-wifi interference. If 2.4 GHz does have to be used then it is recommended that b is turned off. 17/03/2017 6

7 The performance test cases # have not been executed, as the required amount of devices for the test (50+ handsets) were not available during the testing period. Known Issues When not enabling the U-APSD the handset s battery lifetime will last 3 to 4 hours. Therefore it is required to enable this setting at any given time. When U-APSD is enabled on a WAC6500 series 5 GHz radio, the radio will restart every 5 seconds. To prevent this from happening the n rates in the handset need to be disabled. When authenticating with WPA-PSK or WPA2-PSK in combination WAC5302D-S, do not use spaces in the passphrase. Spaces are not recognised as valid characters, although the GUI allows it to enter them and does not provide a warning. Roaming with the WAC5302D-S in combination with 802.1x security takes 200 ms to 250 ms, regardless of radio (Workaround: Use WPA2-PSK in VoWiFi deployments).

In the following chapter you will find screenshots and explanations of basic settings in order to get the ZyXEL Communications Corp solution operational with Ascom i62. Please note that security settings were modified according to requirements in individual test cases. Create a Security Profile. Located under Configuration -> Object -> AP Profile -> Tab SSID -> Second Tab, Security List. 17/03/2017 9

10 Create a new profile by clicking on Add or edit an existing one Fill out the Profile name Select the Security mode Select PSK under Authentication Settings Fill out the Pre-Shared Key o NB. When using the WAC5302 do not use spaces in the pre-shared key Select the Cipher Type. AES is strongly recommended Click on OK to submit the settings Create an SSID. Located under Configuration -> Object -> AP Profile -> Tab SSID -> First Tab, SSID List. Create a new profile by clicking on Add or edit an existing one Fill out the Profile name Select the desired Security Profile Select WMM under QoS Band Select is not required for the i62 as it operates on only one frequency It is recommended not to enable Hidden SSID 17/03/

11 Create a Radio Profile. Located under Configuration -> Object -> AP Profile -> Tab Radio. At least two Radio Profiles need to be created. One to be used by the 2.4 GHz radio and one to be used by the 5 GHz. 17/03/

12 Create a new profile by clicking on Add or edit an existing one Click on Show Advanced Settings to display all settings Fill out the Profile name Select the desired Band Select the desired Channel Width o NB. 20 MHz is recommended for both 2.4 GHz and 5 GHz Select the channel to be used with the Channel Selection o When using fixed channels select Manual and then the desired channels. Be aware that extra Radio Profiles need to be created for the other channels. 17/03/

15 Create a new profile by clicking on Add or edit an existing one Fill out the Profile name Select the correct radio profile under Radio 1 AP Profile Input the desired Max Power Output o NB. Between 12 to 17 dbm is advised Select the SSID Profiles to be transmitted by Radio 1 o NB. It is advised to use only 5 GHz for the i62 Select the correct radio profile under Radio 2 AP Profile Input the desired Max Power Output o NB. Between 12 to 17 dbm is advised Select the SSID Profiles to be transmitted by Radio 2 Adjust the VLAN Configuration as required Enable Load Balancing if desired o NB. The i62 will make its own roaming decisions well before the load balancing feature does need to do anything. It has no impact on the roaming behaviour of the i62 Add the desired access points from the Available list to the Member List. Click on OK Activating U-APSD Open your favourite CLI tool, like PuTTY or Bitvise. Connect to the WLC with your tool. Enter the following commands into the command line: Router(config)# wlan-ssid-profile [default] Router(config-wlan-ssid default)# uapsd Router(config-wlan-ssid default)# exit Router(config)# write Where [default] needs to be replaced with the name of the SSID profile name to which the handsets will connect. NB. Please be aware that this is NOT an optional step, but a requirement for optimal battery performance x usage If 802.1x is used, both the internal and an external RADIUS server can be utilised. ZyXEL Communications Corp supports both the internal RADIUS in the WLC, such as Microsoft NPS or FreeRADIUS. If the internal RADIUS is used the default RADIUS has to be configured in the security profile. Go to Configuration -> Object -> AP Profile -> Tab SSID -> Secondary Tab Security List. 17/03/

16 Create a new profile by clicking on Add or edit an existing one Fill out the Profile name Disable r (not supported by Ascom i62) Keep the Radius Server Type on Internal. Select 802.1X under Authentication Settings. Select default as Auth. Method. Click on OK. 17/03/

18 If an external RADIUS is used it needs to be configured. Configure the wanted external RADIUS under WLAN Controller -> Profiles -> RADIUS Profiles. If the internal RADIUS server of the WLC is to be used, please configure this under RADIUS Server -> General. 17/03/

19 Create a new profile by clicking on Add or edit an existing one Fill out the desired Name of the profile Fill out the Server Address Fill out the RADIUS port as the Authentication Port Provide the NAS password in the Key The complete configuration of the external RADIUS server is beyond the scope of this document. The external RADIUS should have the WLC in it as its trusted NAS device in order to provide 17/03/
