1. Introducing ION-B 1.1 The Features ION-B is an innovative platform designed in order to provide an effective and flexible coverage to a large variety of indoor scenarios. Thanks to its high modularity, its low power consumption, and its full-transparency to protocols and modulation formats, ION-B is the perfect plug&play solution to distribute any wireless standard (including GSM, GPRS, EDGE, CDMA, W-CDMA, and WLAN IEEE 802.
• a variable number of Remote Units (TFAx), whose function is feeding the antenna passive network; • a proper number of indoor antennas, suitable to provide radio coverage to the area. ION-B is fully compatible with any type of indoor antennas; • the optical cables required to connect the 19” subracks to the TFAx. 1.3 ION-B Features The following lines report a brief summary of ION-B main features: • multiband 2G, 2.5G and 3G – 802.
B equipment provides RF splitters/combiners, cross band couplers, attenuators, and duplexers for UL/DL paths, thus allowing maximum in design flexibility; • high reliability: high MTBF (Mean Time Between Failure). 1.4 ION-B Typical Applications Due to its unique features, the ION-B is an ideal solution for radio coverage in a variety of situations: • Multi-operator shared infrastructures: each mobile operator has its own carrier which needs to be transported without interfering the others.
wideband interconnect link option, distances of 20km can be reached. Moreover, these environments require gradual investments, because initially operators tend to provide radio coverage only in the busiest areas, and then extend it in order to reach complete coverage later. The modularity of the ION-B helps operators to gradually expand the system. Often, large cities set up seamless and reliable radio systems for emergency services.

2. Equipment Overview 2.1 Introduction The basic components of an ION-B system (please refer to fig. 2.1.) are the following: • a Master Unit, able to bring the mobile signals from the BTS to different Remote Units and vice-versa, thus remotising the distribution and collection of any mobile signals via fiberoptic cables; • a variable number of Remote Units, conveying and receiving mobile signals through low- power antennas. BTS Remote Unit TFAx ION-B Master Unit Fig. 2.
The Remote Unit (TFAx) is a device which provides optical-to-electrical downlink conversion and electrical-o-optical uplink conversion, thus allowing a bidirectional transmission of signals between the Master Unit and the remote antennas. It is available in 3 different power configurations (Low/Medium/High), housed by 4 different architectures (Case B, Case R, Case R2 and Case F), so as to fulfil different coverage and band requirements.
2.3. The ION-B Master Unit The ION-B Master Unit is a widely-flexible system. Its modular feature allows it to be developed both for simple installation-friendly, unobstrusive applications to complex installations, involving a virtually unlimited number of subracks, and distributed through several floors of a building or through a 20km distance. The following text presents a brief overview of the components of these units.
The variable RF attenuators (TBSI): they provide independent attenuations (adjustable from 0 to 30dB, with 1dB steps) on uplink and downlink RF paths, and allow the designer to optimize the signal level close to the BTSs. TBSI is an override attenuator, its dimensions are: Width = 7TE, Height = 4HE. Fig. 2.
• To connect several BTSs to a master optical TRX. In downlink, the TLCN2 (or TLCN4) combines the RF signals coming from different BTSs into a common RF signal, entering the master optical TRX. In uplink, the TLCN2 (or TLCN4) splits the composite RF signal coming from a master optical TRX into 2 (or 4) RF signals entering different BTSs. The Power Limiter (TMPx-10): it monitors the DL power coming from the BTS and attenuates it by 10 dB in case it surpasses a programmable threshold level.
2.4. ION-B additional options The basic ION-B structure described above can be furtherly expanded or supported by a range of ION-B options, including: • A supervision unit (TSUN), enabling to supervise and manage the ION-B system through any PC or Laptop, thanks to a web-interface supporting the TCP/IP, FTP, HTTP, protocols, and fully compatible with general purpose SNMP managers.
Although the following table tables show a brief overview of the main ION-B additional options, we strongly recommend you to contact your reference Andrew Salesperson or Product Line Manager in order to have For a full overview of the ION-B options, Main ION-B additional options Unit name/ Module name Mechanical Decription Reference Bulletin Reference Manual ION-B Supervision Unit (TSUN 1, 3, 6) PA-100596-EN MN023 Available both as a plug-in card and as a stand-alone unit ION-B Wi-Fi options PA-10
2.5. Block Diagrams In order to better understand the functionalities of the different units and modules, some block diagrams of the ION-B system are presented here. The core of an ION-B system is the ION-B master unit, which generally develops through a passive section (providing Level adjustments, Signal splitting/combining, and Band coupling), followed by an Electrical/Optical conversion (allowing the signal to be distributed through fiberoptic cables to the TFAx Remote Units).
Although TPRF31 proves to be very flexible, complex distribution systems usually can be better served by rack-based ION-B Master Units: such ION-B installations are based on one or more TPRN-subracks, thus exploiting the wide range of ION-B passive cards (TDPN, TMP, TBSI, TLCN2, TLCN4, TLTN, TLDN), in order to build the passive network which best matches the costumer’s needs. Let’s see some examples of such rack-based configurations. Firstly, assume that the BTSs are not duplexed.

3.1. Introduction The Main Tasks of the TFAx Unit: Downlink (DL): • Optical-to-RF conversion of the input optical signal • Automatic Gain Control (AGC) of each converted signal, in order to compensate optical losses; • RF amplification: the converted RF signal is boosted in order to maintain a good signal-tonoise ratio • RF filtering: a proper filter rejects the spurious emissions • RF duplexing and splitting: the boosted RF signal is conveyed to 2 antenna ports (b) (a) (d) (c) (e) Fig. 3.1.
• Automatic Level Control (ALC): the RF signal level is adjusted according to blocking requirements • RF-to-optical conversion of the signal, which is finally conveyed to the output optical port Different Types of Remote Units In order to allow radio coverage with different power and band requirements, the ION-B architecture provides a wide variety of Remote Units. This allows the customer to choose the solution which best fits its coverage and environmental demands.

This configuration reflects a North American scenario, where the coverage needs involve the LMR 800 MHz, LMR 900 MHz, and the PCS 1900 MHz band. In this case, the entire area must be covered by: • two LMR sectors (each one served both by the LMR 800 MHz and the LMR 900 bands); • one PCS 1900 MHz sector. The ION-B configuration required by such a scenario is shown in Fig. 5.

6. Warning and Safety Requirements Environmental Conditions This equipment is designed to be installed in indoor environments. Operating temperature: +5 to +40°C Do not install in corrosive atmosphere or in critical environmental conditions such as hazardous classified areas (1). Installation Site Features A trained technician should carry out the installation of the master unit.
• take into consideration that each remote unit transmits an RF signal and the safety volume must be respected (refer to country regulations for safety volume magnitude); • remote units must be mounted according to installation instructions; • Weight and dimensions of case-F remote units should be carefully considered when choosing the installation site and positioning. During any installation step, please consider the potential risk of any equipment falling or dropping unexpectedly.
when working while the panel is open. When closing the panels, take care not to leave any tools inside the equipment, not to hurt your fingers, and not to trap clothes, bracelets, chains, or long hair. Never remove the cover from a TFAx remote unit or from a TPRN subrack when the power supply is ON. Power Supply Connection Power connection must be carried out following all necessary precautions: • it must be properly made according to the due diligence rules (ex.: EN rules, IEC rules, etc.
Health and Safety Warnings Please be aware that each country or governmental body has established its own specific limits for RF exposure, to which the installation of any radiating antenna must conform. When installing your ION-B system, take care to comply to your local regulations and guidelines about RF exposure limits.
This equation includes the following factors: • G is the antenna gain (in dB) compared to isotropic radiating antennas; • P is the RF power that is present at the antenna connector (in W); • L is the total loss (in dB) between the TFAx remote unit output port and the antenna input port; • S is the maximum allowed power density in air (in W/m2). Its values should be calculated according to the limit exposures to time-variations and magnetic fields.
The maximum allowed power density we have to comply with is: S = 50 W·m2 (typical ICNIRP reference level for occupational exposure to time-varied electric and magnetic fields) By reading the ION-B notes, we know that the output power per carrier at the TFAM antenna port is • 30 dBm ± 2 ( +32 dBm maximum, equivalent to 1.202 W) for the Cellular 850 MHz band • 30 dBm ± 2 ( +32 dBm maximum, equivalent to 1.202 W) for the PCS 1900 MHz band The ½” cable losses are 0.07 dB/m in the 900 MHz band, and 0.
• 26 dBm ± 1 ( +27 dBm maximum, equivalent to 0.501 W) in the UMTS band • The total output power at the antenna port is therefore: P = 0.158W x 2 + 0.200W + 0.501W = 1.345 W, By reading the cable specs, we get that RG223 cable losses can be estimated at 0.55 dB/m. Total losses between the TFAM 91/18/20 output port and the antenna input port can therefore be estimated as follows: L = 0.55 (dB/m) x 10 (m) = 5.5 dB By replacing the above values of G, L, P, S parameters inside the formula 6.
