Antenna – Electronic Communication Systems The RF electric performance of the HB-20 booster conforms to ETSI requirement of the inter modulation and spurious emission. It avoids the interference problem. 3.0 Introduction: Booster Theory / Background In mobile cellular communication system, boosters provide the radio frequency (RF) coverage to areas, which either lack signal, or the required signal strength for adequate mobile phone performance. To the typical user, this translates to the inability to place or receive mobile phone calls in or out of the area, and in most cases will result in a dropped call while entering into the poor coverage area. Insufficient wireless coverage can occur both indoors and outdoors, and may include indoor areas such as office buildings, parking garages, apartment buildings, shopping malls, and residential homes. Outdoor areas are degraded by geographic topologies such as mountains, valleys, dense foliage and high rising urban landscapes which can easily degrade or obstruct the cell site’s signal from the mobile phone. The weak coverage problem can be solved by installing an active booster system, designed for use in a multitude of installation configurations. Booster systems provide an effective solution by redirecting, filtering and amplifying the available signal at the donor antenna, into the weak coverage area, through a properly selected interior coverage antenna. The illumination of the weak coverage area allows the user’s handset to operate as intended within the building or weak coverage area, while maintaining the user’s call clarity and quality, which reduces service complaints and potential subscriber churn.

Antenna – Electronic Communication Systems 4.0 Description of HB-20 Booster installation Kit The HB-20 booster system contains an automatic power control, bi-directional amplifier (BDA) supplied along with a donor antenna (highly directive outdoor antenna) and server antenna (indoor omni directional antenna), specifically designed for interior configurations. The donor antenna must be pointed toward the cell of the base station from where the signal is to be picked up and is usually mounted on the exterior of the building so as to receive the maximum forward signal level from the base station. The indoor antenna of HB-20 booster provides RF signal in all directions downward and outward from the installation point.. A adopter is supplied with HB-20, powered by universal 90/240 VAC mains supply. A standard length of 7 mm RF coaxial cable with connectors is supplied to connect the donor antenna and HB-20 booster. Any other RF coaxial cable length is also available optionally, on request. .

Antenna – Electronic Communication Systems 5.0 System Design and Setup The HB-20 is designed to provide optimal coverage for areas of 500 Sq Meters (5,000 sq. ft) to 1,000 Sq Meters (10,000 sq. ft). However, performance also depends on the amount of in-building shadowing, and the available forward signal level at the donor antenna. Typical coverage is usually planned for relatively small areas such as large conference room or several adjacent rooms in smaller office areas. Indoor coverage varies greatly due to the nature of various building construction techniques and materials. The system design is quite simple & straightforward. The signal from the base station (of the selected Operator) is picked up, preferably on the rooftop. The built in receive signal level indicator in HB-20 booster helps in aligning the donor antenna towards the selected base station & it always shows the received signal level from the base station. It is imperative to monitor the received signal level from the base station, also called downlink signal. Downlink signal may change if some high building, trees or any other obstruction comes in the way of line of site (LOS) between the BTS & the Donor antenna. This may reduce the downlink received signal level & will result in poor service. 6.0 Installing the HB-20 6.1 Pre-installation considerations 1. Once the expected coverage area is determined, identify the installation location for the donor antenna and HB-20 booster. Ensure that the donor antenna has a direct line-of-site to the service provider’s base station. 2. HB-20 installation site location criterion i. A cool, dry location, away from other heat generating appliances or equipment. ii. Accessibility to electric power point. iii. Flat, structural mounting surface. iv. Accommodation for the indoor antenna providing line-of-site coverage to as much of the coverage area as possible. 6.2 Installation Tools You will only need the standard wrenches/hammer/screwdrivers/pliers set for installing the HB-20 booster and donor antenna.

Antenna – Electronic Communication Systems 6.3 Installation Procedure: Do It Yourself To install HB-20 booster, follow the steps as mentioned below: 1. Locate weak signal areas by moving around with a mobile phone and the SIM card of the cellular operator, and check the signal level indicated by the number of bars on the mobile phone display. 2. Similarly, locate donor (outdoor) antenna position by observing the maximum signal received from the base station. 3. Unpack the equipment supplied and check as per the packing list. 4 Mount the donor (outdoor) antenna at the position selected (ref 2 above). 5 Mount the HB-20 booster in the area of weak signal (ref 1 above) 6 Route the RF coaxial cable and interconnect it with the donor antenna and HB-20 booster, which is supplied in the installation kit. 7 Ensure that the three-pin power point has proper earth connection, before switching on the power to booster. Please remember the following important points: i. The RF cable must not be kinked, cut or damaged in any way. ii. Connect the RF cable to the donor antenna taking care to avoid cross threading or stripping. The RF connections should be snug and tight. iii. Seal the outdoor connectors with waterproof sealant (such as M–seal) or the appropriate weather tight boot. 6.4 Power Startup / Alarm Checks / Coverage Testing 1. Plug in the AC/DC Power Adapter power cord to AC main and other side DC plug insert 9V DC socket in Home Booster. 2. When the booster is ON initially all the LED’s will blink two times. 3. The system will automatically control the attenuation to keep the both uplink and downlink output power at a constant level of 10dBm. The system will insert or release the attenuation by 1dB step.

Antenna – Electronic Communication Systems Annexure 2 Trouble shooting procedure HB-20 Conditions Possible Reasons & Solutions A. Initially all the LED’s will blink two times 1 Check the power cord and the AC power socket 2 Please note that the AC main power has to be within the range 90~240VAC 3 Verify the D.C Adapter output voltage is 9V. B. Signals are not amplified after completing the installation 1. Check all the connectors of the repeater system for proper connections. The “BTS” connector has to be connected to donor antenna, and the “MS” connector has to be connected to server antenna. 2. The poor isolation between donor and server antenna will cause system oscillation and it may damage the amplifier of the repeater. It is to note that the repeater gain should be at least 10 db lower than the antenna isolation. C. The system performed well in the beginning but after few days the performance has degraded. 1. The received signal level from the base station might have degraded due to environmental changes such as new building construction and so on. If so, please follow the suggestions below: a. Try to re-align the donor antenna towards the base station b. Adjust the gain attenuation of the Up or Down link direction c. Relocate the donor antenna to solve the problem 2. RF Cable problem: Check the RF cable for physical damage by rats etc. Also check for sharp bands or RF cable pressed. Under these conditions, RF signal losses could have increased. If so, replace RF cable. 3. Indoor structural change: The signal level will vary according to the interiors. Look for any interior changes subsequent to the repeater installation or site survey. If so, adjust the gain of repeater or re-align the server antenna without affecting the existing coverage. D. Alarm indication LED will glow in red colour. It indicates that the received signal level from BTS is high or forward / reverse gain of repeater is high. If alarm persists for a long time contact SHYAM technical support team. File Doc.
