Introduction Repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered. Figure 1 Outdoor Application Figure 2 Indoor Application Ver.2 3 1900 MHz PCS Band Selective Repeater Users Manual Longent dual-band selective repeaters with 2 adjustable bandwidths have filters that can be set to various bandwidths.

A repeater receives, amplifies, and retransmits signals downlink and uplink simultaneously, i.e. from the base station via the repeater to the mobile stations and from the mobile stations via the repeater to the base station. The repeater is connected to a BS antenna, directed towards the base station, and to a MS antenna directed towards the area to be covered. These antennas are connected to the repeater with N type male connectors. Operational and power LEDs are visible on the repeater bottom. The repeater works with convection cooling without fan. Operational parameters such as gain (DGC attenuation), bandwidth, ALC levels, etc. are set using a notebook or keypad locally or remotely via modem with a data interface to the repeater control unit. 3.1.

The signal passes a duplex filter
(DPX), is amplified in a low noise amplifier (LNA), and enters the band selective amplifier (BSA), which has two parallel bands. The first mixer stage on the BSA amplifier, which is controlled by a synthesizer, converts the received frequency down to the IF frequency. The signal is then filtered by a SAW band pass filter and amplified before it is fed to the second mixer stage, controlled by the same synthesizer as the previous one, for converting back to the original frequency. The SAW filter can be adjustable for each BSA has adjustable bandwidth. A detector on the PA measures continuously the output level. The signal from this detector is used by the automatic level control, ALC, to supervise and, if necessary, reduce the output power to keep it under a setting level. The output signal passes duplex filter (DPX) and fed to the repeater service (MS) antenna. The uplink signal path, i.e. from the mobile station through the repeater to the base station, is identical to the downlink path the other way round. Only some levels and component values differ.

Installation A preferable site for the repeater is a tempered and ventilated place. If a repeater is placed outdoor and can be exposed to direct sunshine, it is essential that the air can circulate around the repeater with no obstacle. Do not install or open a repeater at bad weather, such as intense rainfall, snowfall or hail, storm or high wind, extremely low or high temperature and high humidity. 4.1. Mounting 1. Mount the provide bracket Normally, the repeater is mounted on a wall. The mounting bracket is attached to a wall using locking screws. 2. Hang the repeater After attached the bracket, hang the repeater on the two upper supports and use one M5 screw to fasten the repeater to the bracket. M5 clamp screw 11 Ver.2 1900 MHz PCS Band Selective Repeater Users Manual 4.2. Connection 1. Connect antennas Connect the service antenna (MS) and donor antenna (BS) coaxial cables to the N type female connectors marked with MS and BS. 2. Connect repeater to AC supply Plug in the power connector on the bottom of the repeater. 3. Station ground For the repeater supplied from mains, the mains outlet must be grounded. There is a ground screw (M5) on the right side of the repeater. Ver.2 12 1900 MHz PCS Band Selective Repeater Users Manual 5. Operation and Maintenance 5.1. WEB Interface 5.1.1.

Keypad Interface Longent repeater can be operated via a keypad interface, which offers three main menus: View Menu, Configuration Menu and Warning Menu. There are five key buttons: Menu, Up, Down, Enter, Back and a LCD panel. The Menu key is used to launch the main menus and enter the corresponding submenu. The Up and Down key are used to scroll through the submenus within current main menu, and also will be used to modify the blinking bit of data by one digit increment or decrement in editing state. The Enter key is used to start and end the editing operation, also alter certain bits of data in editing state. The Back key is used to turn back to the upper menu or cancel the current operation in editing state. It should be noted that the system does not respond to any key for 15 seconds boot process when power up the repeater. Ver.2 25 1900 MHz PCS Band Selective Repeater Users Manual 5.2.1. Menu Tree Ver.2 26 1900 MHz PCS Band Selective Repeater Users Manual 5.2.2. View Menu Output Power Display The Output Power Display menu shows the instantaneous power of the repeater. This screen shows that the composite power is 30 dBm on the output of downlink, while the composite power is less than 3 dBm on the output of uplink. When the power is less than 3 dBm, the display will show -- instead of a usual digit. ALC Attenuation Display The ALC Attenuation Display menu shows whether or not the gain is being actively attenuated by Automatic Level Control to keep the power under a certain level. DGC Attenuation Display The DGC Attenuation Display menu shows the value of Digital Gain Control attenuation, which is used to adjust the maximum gain of the repeater. ALC Setting Display The ALC Setting Display menu shows the Automatic Level Control points that determine the limits of the composite power for output. Ver.2 27 1900 MHz PCS Band Selective Repeater Users Manual PA Temperature Display The PA Temperature Display menu shows the temperature of PA modules in centigrade. VSWR Display The VSWR Display menu shows the VSWR value of the repeater terminals. Gain Display The Gain Display menu shows the current gains of the repeater. The gain is determined by the equation:
Gain = 85 dB (DGC Att.) (ALC Att.) Pass Band Display The Pass Band Display menu shows the frequencies of the two pass bands. Ver.2 28 1900 MHz PCS Band Selective Repeater Users Manual PA Enable Display The PA Enable Display menu shows the working status of the PA modules, i.e. on or off. Ver.2 29 1900 MHz PCS Band Selective Repeater Users Manual 5.2.3. Configuration Menu Pressing the Menu key will begin to enter the Configuration Menu, which is selected in the main menus. A password is requested from the user with the first digit blinking, the Up and Down keys are used to change the blinking digit, the Enter key is used to confirm the blinking digit and shift to the next one. The password consists of 4 digits and defaults to 4 zeros: 0000. Successful password will permit the user to configure the repeater. ALC Level Setting Press Enter key to start edit, the first digit of uplink ALC will blink, then press Up or Down key to select a desired value, press Enter key to confirm it and shift to the next one. When the setting of the second digit is finished, the display will steady. Pressing Down key that the star will switch to the downlink, the process is the same. This screen shoes that the uplink ALC Level is set to 24 dBm, and the downlink ALC Level is set to 30 dBm. Ver.2 30 1900 MHz PCS Band Selective Repeater Users Manual DGC Attenuation Setting The DGC Attenuation setting process is much the same as the ALC Level setting process. PA Enable Setting Press Enter key to start, the Up key and Down key can be used to trigger on or off, and press Enter key again to end. Pass Band Setting Press Enter key to start, after setting the low-end frequency and high-end frequency of pass band 1 on downlink, press Enter key to end. The frequencies on uplink are set automatically upon the downlink band. Change Password The screen asks for the current password. If the current password is entered successfully, it will allow the user to create a new password. Pressing the Enter key for the last digit of the new password will save the new password for the future. A password can consist of 4 digits from 0000 to 9999. Ver.2 31 1900 MHz PCS Band Selective Repeater Users Manual 5.2.4. Warning Menu Any of the following alarms will cause a warning in the Warning Menu.
