Site Requirements 90DIB500R41SR_FCC02 – 99.1 15 DIB-500 R4.1 Safety regulations Safety measures 16 Site Requirements 90DIB500R41SR_FCC02 – 99.1 DIB-500 R4.1 Product description 3 Product description The Digital Indoor Base Station (DIB-500 R4.1) is used as a base station in ACCESSNET®-T IP networks. The base station is responsible for radio coverage in a defined radio coverage area. For this purpose, up to eight carriers are available depending on the antenna coupling variant. It can thus provide as many as 32 radio channels (four radio channels per carrier) for the communication of the mobile terminal equipment, via which voice and data is/are transmitted in accordance with the TETRA standard (Terrestrial Trunked Radio). In addition, in networks with a distributed switching architecture, the DIB-500 R4.1 can take on the routing function and thus act as a full system controller node. Moreover, further functions are available; applications, for example, can be connected directly to the ACCESSNET®-T IP by means of an IP connection. The carriers are provided via the transceiver module TETRA Indoor Base Transceiver (TIB) that can accommodate up to two carriers. Two TIB transceiver modules may be incorporated in the equipment rack of the DIB-500 R4.1, thus providing four carriers. From five carriers, a second equipment rack is used, which can also provide up to four carriers. Two TETRA antenna connections and one GPS antenna connection (Global Positioning System, GPS) are available for connecting antennas. Internally, the antennas are coupled via the antenna coupling system. In the FlexibleTx variant, project-specific external antenna coupling systems can be used for this purpose. For optimum reception properties, antenna diversity is available. Depending on the requirement, the ACS can provide the following antenna connection variants: Hybrid Cavity High Power or FlexibleTx For communicating with other base stations and with the IP Node (IPN) network element, the DIB-500 R4.1 features Ethernet interfaces for linking to the IP transport network. If all the connections to the other network constituents break down during operation, the DIB-500 R4.1 ensures radio operation within its own radio cell. If the DIB-500 R4.1 is operated with a separate routing function in networks with a distributed switching architecture, the base station additionally collects call detail records (CDR).

In addition, equipment for protecting the antenna cables against lightning must be provided. 4.1.6 Adjustment of the GPS antenna Each equipment rack features a separate GPS antenna connection but only one GPS antenna is required per network element DIB-500 R4.1. For network elements made up of multiple equipment racks, the clock and time reference signals are synchronized. Additional GPS antenna recommended For DIB-500 R4.1 with more than two TIB transceiver modules and controller redundancy, the use of an additional GPS antenna is recommended to ensure the GPS synchronicity of the entire base station in case the active controller fails. Without GPS satellite reception the proper operation of the DIB-500 R4.1 is ensured for one year (depending on the ambient conditions) if a GPS signal was received before at least once. The 24 GPS satellites in total are not positioned geostationarily. For this reason, the location of the GPS antenna must be chosen to ensure that the reception is not impaired/disturbed by any obstacles. It is best to install the GPS antenna on the roof of a building. It is also possible to install it on an upright mast with a diameter of 60 mm. Irrespective of the installation method used, always ensure a good circumferential visibility (angle for unobstructed sight of the sky according to the recommendations of the manufacturer). The angle of the GPS antenna supplied is 90 °. The orientation of the GPS antenna must ensure that at least four satellites are received. A minimum distance of 5 m must be kept between the GPS antenna and the Tx antenna(s) since the decoupling established must be as large as possible - especially for carriers in the range of 393 to 395 MHz, since the fourth harmonic wave in this case is in the range of the received signal of the GPS signal. For specifications on the cables required, please refer to section 5.1.2 on page 32. Site Requirements 90DIB500R41SR_FCC02 – 99.1 25 DIB-500 R4.1 Requirements concerning the operation room Environment Responsibility for the installation, commissioning and maintenance of the GPS antenna The operating company is responsible for the proper installation, commissioning and maintenance of the GPS antenna unless this is an integral part of the contract concluded with Rohde & Schwarz Professional Mobile Radio GmbH. The operator is responsible for ensuring that: the installation location of the GPS antenna is appropriate for installing an antenna, e.g. the roof or wall of a building or an antenna mast. an antenna mast, if used, including any required retaining elements are installed in such a way that they are protected against outside influences, e.g. a storm. equipment for overload protection and lightning protection of the GPS antenna has been provided at the installation site.
