  • Page 14: Network Integration

    Network integration Network integration The MobileConnect&CinemaConnect product can be used as a standalone system or can be integrated in your existing network infrastructure. To choose the most suitable configuration please read this section carefully. Selecting the network mode The ConnectStation allows for two different network modes. The mode is selected during initial setup of the ConnectStation in the Admin Interface.

  • Page 15: Standalone Mode

    Network integration Standalone Mode Standalone Mode is the easiest to configure if you do not need the ConnectStation to integrate into an existing WiFi infrastructure. Any Ru- ckus Access Point connected to LAN1 is considered to be the “delivery sub- net”, and is assumed to be there for the sole purpose of delivering the streams of a single ConnectStation.

  • Page 16: Using Multiple Access Points

    Network integration Using multiple Access Points ► ▷ Instead of a single AP, you can add up to 8 APs via an external network switch to extend the range of the delivery WiFi. ▷ The APs can be associated and configured via the administration inter- face of the ConnectStation.

  • Page 17: Increasing The Number Of Clients Per Connectstation (Standalone Mode)

    Network integration Increasing the number of clients per ConnectStati- on (Standalone Mode) In order to increase the number of clients per ConnectStation: ▷ Add two or more Access Points via LAN1 (see "Using multiple Access Points"). This is necessary in order to ensure the quality of the audio. A single AP cannot provide low latency unicast audio stream to 100 liste- ners.

  • Page 19: Increasing The Number Of Clients Per Connectstation (In- Tegrated Mode)

    Network integration Increasing the number of clients per ConnectStati- on (Integrated Mode) In order to increase the number of clients per ConnectStation in Integrated Mode: ▷ Make sure that your network and WiFi infrastructure can handle the in- creased number of clients. Otherwise enabling more clients may lead to audio and connectivity problems for all listeners.

  • Page 24: Cluster Discovery (Integrated Mode)

    Network integration Cluster discovery (Integrated Mode) When integrating multiple ConnectStations into a network, they need a way to find each other to set up the cluster. There are two options: 1. Explicit server selection via DNS SRV records 2. Automatic discovery by multicast announcements (with the opti- on to override the default multicast address and port) Order of methods for Cluster Discovery The discovery process follows a strict order:...

  • Page 25: Explicit Server Selection

    Network integration Explicit server selection You can explicitly set any of 1, 3 or 5 ConnectStation(s) as a server for your cluster. For that purpose, create a SRV record for _cnct._tcp pointing to the IP (or, if set in your DNS, hostname) for each of the ConnectStations you want to select as a server.

  • Page 26: Overriding The Default Multicast Group Address And Port For Multicast Announcements

    Network integration Overriding the default multicast group address and port for multicast an- nouncements You can override the default multicast group address and port for announ- cements by adding a _cnct._udp SRV entry into your DNS. ConnectStations will then use the specified address/port for cluster discovery via multicast announcement (as well as for Client’s Discovery).

  • Page 27: Service Discovery (Integrated Mode)

    Service discovery (Integrated Mode) Similar to the discovery process between the ConnectStations, the smart- phone clients running our MobileConnect/CinemaConnect App (“the App”) need a way to find at least one ConnectStation in your network. The pro- cess is roughly similar to the cluster discovery described above, except the DNS SRV records are accompanied with a single PTR record to adhere to the DNS-SD specification more closely.

  • Page 28: Automatic Discovery Via Multicast Announcement

    Network integration Example: 1. Let‘s assume that you want to register a cluster of three ConnectSta- tions in your DNS. They discover each other with any of the Cluster Dis- covery methods described above. 2. Your DHCP hands out IP addresses to the ConnectStations connected via their LAN2 port- we’ll assume they are: 192.168.0.101, 192.168.0.102 and 192.168.0.103.

  • Page 29: Discovery Via Hostname "Sennheiser-Connect

    Discovery via hostname “local.connect” The final service discovery was used by ConnectStation releases prior to 3.0.0 supported mainly for legacy installations. Similar to the “sennheiser- connect” hostname, a single ConnectStation serves as the entry point for Apps. It has to be registered with hostname “local” under the top-level do- main “.connect”.

  • Page 30: Setting A Single Search Domain With Dhcp Option 15

    Windows-based clients seem to ignore any domain after the first entry in this list. On Android, our Apps (MobileConnect and CinemaConnect) correctly use the full list of search domains passed via Option 15 to look up PTR and SRV records.

  • Page 31: Wifi Planning

    Network integration WiFi planning Please observe the following information when planning the WiFi setup of the ConnectStation for Standalone Mode. The same recommendations can also be taken into consideration for WiFi planning with different Access Points or in Integrated Mode. WiFi coverage The system‘s WiFi coverage is determined by the access point, the recep- tion quality of the connected devices and the environmental conditions.

  • Page 32: Wifi Design

    Network integration WiFi Design For designing the WiFi system, please observe the following steps: ▷ Define the number of access points (max. 50 clients per each Ruckus ZoneFlex 7372 AP recommended). ▷ Determine the room size, shape and RF conditions of the facility. The best performance is achieved: ▷...
