Hardware Overview Supported Cisco WiMAX Antennas The antenna is connected to the QMA, panel-mount, 50-ohm connector located on the faceplate of the module. For more information about antennas, including installation procedures, see Cisco 1240 and 1120 Connected Grid Router Hardware Installation Guide. Table 3 lists the Cisco antennas that are supported for use with the module and the Cisco 1240 Connected Grid Router.

Hardware Overview The module provides two physical connectors for antennas. Module States The WiMAX module has the following states: Table 5 WiMAX Module States State Description Configured In this state the WiMAX module has all the necessary configuration information and can be started by the port manager. Modifications to configuration parameters using the configuration file require re-initialization of the WiMAX module.
Hardware Overview Radio Frequency Interface The Radio Frequency (RF) interface consists of two QMA connectors on the faceplate labeled MAIN and AUX. Both antennas are mandatory; it both transmits and receives RF. The second AUX QMA connector is for the optional RX Diversity. DC Power Consumption The average DC power consumption according to the duty cycle is as follows: Table 6 Power Specifications WiMAX 1.
Installing and Removing the WiMAX Module Note • The module unit defaults to the Normal state when VCC is first applied. Disconnected mode—No power to the module. The host power source is disconnected from the module and all voltages associated with the module are at 0 V. CGR 1120 and CGR 1240 controls the power to the module, therefore the host can stay powered on and cut the power in order to put the module into the disconnected state.
Installing and Removing the WiMAX Module Warning To prevent airflow restriction, allow clearance around the ventilation openings to be at least: 1.75 in. (4.4 cm) Statement 1076 Installing the WiMAX Module The WiMAX module can be installed into any slot of the CGR 1240, however Slot 6 is recommended due to the ease of installing the available cable. Note Some WiMAX modules are installed into the host router at the factory.
Standards Standards The following standards apply to the Cisco Connected Grid Modules for CGR 1000 Series—WiMAX. Table 7 General Standards Standard Definition IEEE 1613 2009 IEEE Standard for Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations Regulatory and Compliance Information For regulatory compliance and safety information for the module, refer to the Connected Grid Router 2000 Series Regulatory Compliance and Safety Information document.
Software Overview For more on the WiMAX technology, see the following: http://www.cisco.com/web/about/ac123/ac147/archived_issues/ipj_11-2/112_wimax.html WiMAX Link QoS QoS is configured on the base station. The IEEE standard 802.16e provides the ability to define Quality of Service (QoS) for different data streams. It contains definitions of available parameters and scheduling types. The responsibility of QoS is split between the base station and the mobile stations.
Software Overview Router(config-if)# show interface wimax 4/1 service-flows sfid 8091 Sfid : 8091 CID : 1026 Basic CID : 3 Type : data State : active Direction : Downlink SAID : 65535 Encryption algorithm : None Authentication algorithm : None Scheduling type : Best-effort service Delivery service : best-effort QoS set : Provisioned set Traffic priority : 3 Max rate : 30000000 Max burst : 1000000 Min rate : 0 Max latency : 1000 Tolerated jitter : 1000 Grant interval : 0 Polling Interval : 0 QoS set : Admit
Software Overview QoS Parameters The following are configurable QoS parameters available on the base station: • Traffic priority—This parameter defines the priority assigned to specified service flow. Services with higher traffic priority should be given lower delay and higher buffering preference. However this parameter should not take precedence over any other QoS parameters. The specific algorithm for traffic priorities depends on vendor solution.
Configuring the Module • CS specification—This parameter defines convergence sublayer which should be used for this service flow Additional QoS Commands • (config-scan-list)# nap id nap-id priority priority channel-index channel-index • (config-scan-list)# nsp id nsp-id {home | priority priority channel-index channel-index} Configuring the Module The module is configured using the system software.
Configuring the Module • When a WiMAX module operates in a network with an Airspan base station that has a MAC profile definition based on non-authentication, some of its base station models might require the privacy key management (PKM) to be configured on the WiMAX interface. Updating the base station with the latest firmware generally eliminates the need to change the configuration of the WiMAX module. WiMAX Interface Security The WiMAX module supports the following security methods: • IEEE 802.
Configuring the Module EAP-TLS and EAP-TTLS Authentication Methods To set up a username and password for the Pairwise Key Management (PKM) of a CGR 1000, the WiMAX module must be installed and running. CGR 1000s that ship with a pre-installed WIMAX module will have a pre-installed WiMAX configuration. You can configure your WiMAX interface for one of the following authentication methods: • No Authentication (Open) • EAP-TLS Authentication The WiMAX interface uses trustpoints in the following manner.
Configuring the Module Step 1–WiMAX Scan-list Configuration To create a scan-list, issue the following commands: Router# configure terminal Router(config)# wimax scan-list aaa Router(config-scan-list)# channel index 1 frequency 2350000 bandwidth 10000 Router(config-scan-list)# nap id 00:00:01 priority 1 channel-index 1 Router(config-scan-list)# nsp id 00:00:01 home • NAP (Network Access Provider)—The base station. It provides access to the NSPs which provides network connectivity.
Configuring the Module Note *—The command, pkm trustpoint device device_cert_trustpoint, is not needed if 1) EAP-TLS is using the embedded Airspan certificate, or 2) if EAP-TTLS is used.
