1. Preface Personal mobile communication is now part of daily life and persons have come to expect a robust network that meets their increased demand for an always-on network that provides seamless coverage and unlimited bandwidth at high speeds. Cellular repeaters are an integral part of achieving this goal. A cellular tower in a non-metro environment typically supports a large number of users but is affected by a relatively small coverage footprint.
2. Introduction JDTECK has engineered an advanced industrial grade digital repeater for Distributed Antenna Systems with the ability to function in either a wideband or narrow band mode. This core component helps create the perfect solution for providing a wireless improvement in the cellular reception of a large office or apartment building, hotel, underground parking garage or remote outdoor location.
3. DAS Installation 1. The repeater’s main function is to improve weak RF signals to an area. 3.1 Installation Procedure Site Survey 2. Selecting the appropriate accessories that are compatible with this digital frequency repeater is very important for optimal system performance. Since this is a multiband repeater, it’s important that all the peripheral components used in the DAS supports all the frequencies that are going to be needed and that all the components are Low PIM rated. 3.
3.1 Installation Procedure – Cont. 9 Check the contents supplied against your packing list & DAS design. Identify a suitable location where the donor antenna will be installed on the roof or at an elevated location free of any other antennas or immediate obstructions. Confirm this location has the best input signal for the carriers you would like to support using test equipment. Ensure the location is properly isolated from any of the indoor service antennas so as to avoid signal oscillation.
3.3 Installation Procedure – Repeater Mounting. 3.3 Installation Procedure – Repeater Mounting Cont. The JDTECK industrial digital repeater is designed to be mounted on a wall. Carefully remove the repeater from the box and place it upright on a protected surface like cardboard or carpet. Then remove the mounting bracket from repeater and securely bolt bracket to the wall. Be sure to use a plumb level so the bracket is perfectly straight when completed.
4. Installing the Graphic User Interface. (GUI) A USB thumb drive is shipped with each repeater which has the GUI program stored on it. Install the GUI program onto a Laptop PC that will be used to initially access and configure the repeater. Please note that the GUI can only be initially accessed via a USB cable connection. You will also need to have an internet connection to download Java. 4.1 Installing the GUI. (Con’t) Java Development Kit is required to run the GUI.
4.2 Installing the GUI. (Con’t) 4.3 Accessing the GUI. You will then be show several options to choose from. Scroll down to Java SE Development Kit 8u92 and select “Accept License Agreement”. Then choose the operating system compatible with your PC. After you have installed the GUI program and restarted the PC, the user will first switch the repeater ON and wait for the boot sequence to complete. This is indicated by the LED’s at the bottom of the repeater. The LED’s turn from RED to GREEN.
4.4 Accessing the GUI. (Con’t) If the GUI screen comes up blank, it’s because Java did not install correctly. It would be easiest to just reinstall the program again from the thumb drive where you would again be prompted to download the correct Java Kit and restart the install sequence. Upon a successful installation, the following screen will appear. Here you will select the connection type (USB), the device type (DR-27) and the COM Port.
5. Using the GUI. (BAND SELECT) 5.1 Using the GUI. (SET PARAMETERS) The GUI is inherently intuitive and very user friendly. The user simply selects the bands they would like to support and click confirm. They can choose from either the preset band selections or customize a selection as needed. In the custom selection mode, the user can select all the bands at the very top which will activate all the blocks within the bands. This will allow the repeater to run in wideband mode. (All Channels in All Bands).
5.2 Using the GUI. (SET PARAMETERS) 5.3 Using the GUI. (DASHBOARD) On this page, the user also has the option to select up to any 5 bands they would like the QUICK VIEW DIALS to monitor which dynamically display the DL output power over on the DASHBOARD page. The DASHBOARD page provides an overview of how the repeater is functioning. The view of this page dynamically changes depending on if the repeater is operating in preset or custom mode. 4. Using the GUI.
5.4 Using the GUI. (REGISTER) 6. Testing. (Flow Chart) The REGISTER page allows the user to document the contact details of who owns the repeater as well as who installed it. A warning label is also displayed on this page. 5.5 Using the GUI. (VIEW LOGS) The VIEW LOGS page allows the user back and review the type, value, band, date and time an alarm occurred. They also have the option to download the logs to excel.
7. Troubleshooting Q1. Why is there still no signal after installing the equipment? Answer: 1. Check the power on repeater and power supply. 2. Check the connector of outdoor antenna is tight or not. 3. Check the connectors of RF cable are tight or not. 4. Check the outdoor signal is strong enough or not. 5. Check to make sure the antenna is installed correctly. 6. Check the connector of indoor antenna is tight or not. 7. Check the cable type is suitable or not. 8. FCC Statement 1.
