KIRK Wireless Server 1500 Installation and Maintenance 2. Capacities and Specifications 2.1 Overview A KIRK Wireless Solution, based on the KWS1500, is an adjunct solution for medium-to- large businesses with a need from anywhere between 1 and 128 handset users. The KIRK Expansion Board and the KIRK Link Card make it possible to expand the solution capacity to reach registration of up to 128 and 700 wireless users depending on the interface technology. The KWS1500 is deployed behind a new

KIRK Wireless Server 1500 Installation and Maintenance When using linked KWS1500s, the solution uses the ARI number from the KWS1500 assigned as the Master. KIRK Handset IPEI number Each KIRK Handset has a unique Equipment Production Identification number. This number uniquely identifies each handset. The KWS1500 assigns each handset to the solution by its International Portable Equipment Identity (IPEI) number, or serial number. The IPEI number is printed on the label inside the battery

Radio Coverage and Physical Deployment 3.1 Radio Coverage Areas The deployment of Base Stations and Repeaters is a critical aspect of the KWS1500 Wireless Server. If the Wireless Server installation is to be successful, the deployment concepts explained here must be followed. To determine the permanent installation location of Base Stations within a given installation, a site survey must be taken to discover the optimal location an

Coverage Area Calculations One Base Station: 2 Coverage A = ( π x r ) Extending Radio Coverage with Repeaters A KIRK Repeater is a useful tool for extending a Base Station’s coverage area. It is therefore ideal where extra coverage is required in a low traffic area. KIRK Repeaters do not prov

KIRK Wireless Server 1500 Installation and Maintenance Multi Cell Environment In a multi cell environment, up to 3 Repeaters may be synchronized to a single Base Station to extend the radio coverage. Jump Configuration Repeaters may also be configured in a “jump” configuration. In this configuration the Repeater closest to the Base Station is the only Repeater in the chain that is synchronized to the Base Station. Subsequent Repeaters are synchronized to the previous Repeater in the

If the overlap area is not enough (less than 9 to 14 meters / 30 to 45 feet), there is a risk of dropping the connection while moving from one coverage area to another. This is because of the time that the handset needs to scan for an alternative Base Station. However, too much overlap results in a wasted coverag

KIRK Wireless Server 1500 Installation and Maintenance Horizontal and vertical overlap Base Stations are omni-directional, meaning RF signal is propagated vertically and horizontally from the Base Stations and Repeaters. Depending on building materials, the Base Station coverage area will typically extend to more than one floor of a structure. In the multi-zone building installation below, the coverage areas overlap horizontally, allowing the handset to roam the structure without interrupt

KIRK Wireless Server 1500 Installation and Maintenance No overlap In areas where two Base Stations are separated by steel doors, gates, elevators, stairwells, etc., the handset may not have time to register with the next Base Station, resulting in the call being dropped. This can be resolved by moving the Base Stations closer together, or by installing another Base Station near the obstruction. If the overlap area is not enough (less than 9 to 14 / 30 to 45 feet), there is a risk of dropp

KIRK Wireless Server 1500 Installation and Maintenance Many small overlaps Be aware that many small overlaps in the same area can create problems if a handset can only identify two Base Stations. For example, if the handset is located in such an area and it is moved in a given direction, the alternative Base Station chosen may be different than the Base Station towards which the handset is traveling. This situation can cause a dropped call. The best solution is to place a Base Station in

KIRK Wireless Server 1500 Installation and Maintenance Shadows Be aware that “shadows” created by parts of the building can cause spots where no radio signals are able to penetrate. If a Base Station is mounted on a concrete or steel pillar, or even mounted near steel shelves, shadow areas may occur. This should be resolved by placing extra Base Stations near the shadow areas. Firewalls/doors, metal siding or linings, etc., might create these shadows. Weather conditions and seasons of t

KIRK Wireless Server 1500 Installation and Maintenance RSSI value The Radio Signal Strength Indicator value is a relative expression for the field strength of signal from the Base Station. The RSSI value is used for the choice of the alternative Base Station(s). The handset will choose the Base Station from which the strongest RSSI signal is received as the first alternative Base Station. Alternative Base Stations are listed according to RSSI values. If the “Best alternative Base Station

KIRK Wireless Server 1500 Installation and Maintenance 3.7 KIRK Radio Hardware KIRK Base Stations KIRK Base Stations are compact devices that contain RF circuitry and transmit/receive antennas. The main function of the Base Station is to provide audio and data communication between the handsets and the KWS1500. The KIRK Base Station controls the traffic channels in the air and works as a link between the handsets and the KWS1500. The KWS1500 operates the Base Stations through a wir
