Maximum Permissible Exposure (MPE) calculation for frequency bands MPE calculation for 395MHz, 446MHz, 791MHz, 2540MHz NOTE: Limits according to FCC. The following calculations are used to estimate MPE distance for a single band and for multiple bands: Parameters for calculation: Pn = Maximum measured conducted power for each single path, 43.75 dBm = 23,714 mW G = Maximum antennas gain (w/o cable loss) = 14dBi, 11dBi, 8dBi, 5dBi Gn = Maximum antenna gain 13.617, 12.589, 6.309, 3.
Combined Bands: x x x x Each idRU supports up to four bands that are combined in one PLEXER into one antenna port. Each band can transmit up to +43.75 dBm (23.714W). All four bands can transmit four times the power, +49.75dBm (94.856W). When more than one operator operates the band, the power budget is divided between the operators automatically. For example, when two operators using same band (different frequencies), each operator has a maximum output power of +40.75dBm (+43.75dBm / 2 = +40.75dBm).
Equation for minimum distance for multiple bands: R Worst case scenario when all bands are active. ANTENNA GAIN 14dBi 11dBi 8dBi 5dBi R- MINIMUM DISTANCE 524.37 cm 371.22 cm 262.80 cm 186.

2 Topology Examples This chapter provides examples of the following types of topologies and applications x Basic topology x Cascaded idRUs x Master Slave topologies x Redundancy driven topologies – RF source and dual-system redundancy driven topologies x Special applications such as single CPRI link, idDAS for Australia, and WCS applications. NOTE: Additional topologies are supported. Each type of topology requires the appropriate setup and configuration procedures. 2.
2.2 Cascaded idRU Topology This topology supports up 36 idRUs connected to the MSDH in cascades or ‘strings’ of up to six remotes per string. The first remote in the string is connected directly to the MSDH, and the remaining remotes in the same string are interconnected. All connections are CPRI based. This provides more coverage per fibre optic link between the MSDH at the headend and remotes. The following figure illustrates the connections for a single cascade. Figure 2-2.
2.3 Master Slave Topologies This topology provides single source management for two cascaded MSDH units. A total of 36 idRUs are supported for the installation that includes both MSDH units. In this type of installation, the two MSDH units are cascaded and each MSDH unit interfaces to dedicated idRUs or idRU cascades referred to as ‘strings’. Depending on the required capacity, the MSDH units can be fed from either a single MTDI connected to the Master MSDH, or each MSDH may be fed from a dedicated MTDI.
2.4.1 RF Source Redundancy Driven Topologies The RF source redundancy driven topology supports end-to-end cell resource redundancy for a system with up to 36 cascaded remotes, installed in strings of up to six remotes per string. Each remote in a cascade has access to two independent RF feeds that include BTS farms, MTDI, and MSDH units. Redundancy is provided per individual cell resource in each remote.
Figure 2-6. Illustration of an RF Source Redundancy Driven Topology This area is intentionally left blank… Cobham Wireless idDAS Installation and Maintenance Guide 00109GU Rev. 2.
2.4.2 Dual-System Redundancy The dual-system redundancy driven topology provides full, end-to-end redundancy consists of two independent systems, where only one of the systems transmits RF at any one time. By default, the user designated ‘Active’ system transmits RF, and the designated Standby system is muted. If a fault is detected, switchover occurs. Each system consists of an independent set of BTS, MTDI, MSDH, and idRU units.
The following figure illustrates a dual system redundancy installation with Master-Slave MSDH and multiple MTDIs per system. The MTDIs can be connected to the same MSDH or to dedicated MSDH units. Figure 2-8. Example of Dual-system Redundancy Topology with Master-Slave and Multiple MTDIs Cobham Wireless idDAS Installation and Maintenance Guide 00109GU Rev. 2.
2.5 Additional Applications This section describes special topologies for specific types of requirements. The general architecture and the system elements operate as described in section 1.2 however the connections are specific to each type of special topology.
Figure 2-10, provides a detailed block diagram of the same topology for Australia. Note the following: x The CPRI link must support the needed capacity. x The topology is implemented for the usage of three operators, where some bands are allocated to one operator, some to two operators and some to three operators. x Headend elements: x The APOI, MTDI and MSDH installations are standard as described in Chapter 3. x Two APOI and two MTDI units are required for this topology.
2.5.2 WCS Applications To implement a MIMO configuration of WCS and 700/850/1700/1800 bands, three idRUs are required: x Two quad-band idRUs supporting 700, 800, 1700 and 1800 MIMO A and MIMO B bands; x One idRU supporting two 2300 LTE TDD filters, amplifiers and antennas ; Each quad-band idRU receives its bands along with the 2300FDD band from the MSDH via a dedicated CPRI link. The filtered and amplified services from each idRU are forwarded to the idRU 2300 TDD, along with the 2300 TDD.
2.5.3 Five Band SISO Configuration The five-band SISO configuration distributes five bands (800, 900, 1800, 2100 and 2600) over a single antenna infrastructure connected to one of the repeaters (Main). All five bands are transferred over a single CPRI connection from the MSDH. The Main idRU conditions four of the bands and the Aux idRU conditions one of the bands (2100). All five bands are then distributed over the same antenna infrastructure connected to the Main idRU.
2.5.4 Multi-Operator Eight Band MIMO Configuration The eight-band MIMO configuration routes eight bands (800MIMO, 900, 1800MIMO, 2100 and 2600MIMO) over a single CPRI link, for conditioning and distribution at the remote end over two remote units with dedicated antennas. All eight bands are transferred over a single CPRI connection from the MSDH. The Main idRU conditions and distributes four of the bands; the Aux idRU conditions and distributes four other bands.

For more information on the dual-system redundancy topology, refer to Section 2.4.2.
4.5 RF Source to idDAS Connections This section details the RF source to APOI and to MTDI connections. Depending on the size of your system and your familiarity with the idDAS elements, you may either directly perform the connections according to your plan or open an Admin level session to the MSDH and use the BTS Port Wizard tool. The tool is briefly described in Section 4.5.3 and detailed in the idDAS Web Management Guide. 4.5.
4.5.1.2 BTS to APOI Simplex Connections Referring to your installation plan for the connections: 1. Connect the BTS simplex connections: x BTS UL to Band Module UL x BTS DL to Band Module UL/DL 2. For BTS DL > 30dBm, use a Low PIM attenuator. Note the following: x For Simplex connections requiring attenuation, only the DL signal is attenuated to the duplex port. x Verify that the UL BTS interface signal strength corresponds in gain value to the DL BTS interface gain value.
The two A-POI channels on each APOI Band Module are combined; as such, the frequencies must be of different ranges within the band. As illustrated in Figure 4-18, the two combined APOI bands are physically routed towards as single MTDI channel. This enables each MTDI module to support up to four APOI channels. 2X CHANNELS UL1 DL1 A-POI BTSI A COMBINED MTDI RF MODULE UL2 DL2 A-POI BTSI B COMBINED 2X CHANNELS Figure 4-18.
4.5.3 Wizard Guided RF Connections The BTS Port Wizard is a tool provided by the idDAS Web Management. It can be used to facilitate the installation procedure by guiding you through the connections between the RF source and the APOI and MTDI. This ensures that the registered BTS Ports correspond to the physical connections. The BTS Port Wizard is accessed by opening an MSDH session. The tool is detailed in the idDAS Web Management Guide.
