System Shape and Functions 4.1 System Shape The iDEN (Integrated Digital Enhanced Network) RF repeater was arranged to efficiently utilize component modules when operators compose and operate the iDEN service network. The iDEN RF repeater is basically installed on the wall, has a structure to be installed on a 19 inch rack as necessary, and is provided with ground terminals on the lower part of repeaters for grounding. < Fig. 4 > System shape 4.
iDEN Heat radiation fin Hinge < Fig. 5 > External appearance of cabinets 4.3.1 Latch Latches was made to improve airtightness in performing a role important for cabinet characteristics such as rain-proofing functions, vibration, etc. and to secure safety because of locks. It was made convenient in opening or closing doors with an automatic raising function of heads and was made to avoid swing by minimizing shaft gap of latches.
iDEN 4.3.2 Hinge This was designed by considering convenience and promptness when opening and closing cabinets during assembly and maintenance of cabinets and has 3 kinds of advantages such as a torque function, stopper function, and separated angle function. < Separated angle> Torque function realization A stopper function when opening cabinets Separation when opening cabinets < Fig.

iDEN 4.3 System configuration and functions The iDEN (Integrated Digital Enhanced Network) RF repeater is composed of PSU(Power Supply Unit), RCU(RF Control Unit), Up / Down Converter Module, PAU(Power Amplifier Unit), Filter, and Isolator Check module. < Fig.
iDEN 4.3.1 PSU (Power Supply Unit) This is used to supply stable DC power to each device provided with active elements through A/D conversion and D/D conversion by receiving AC power, uses semiconductors for industry or higher in terms of major activation elements, is mechanically strong, and satisfies all electrical characteristics. A power used, it is supposed to receive 108~127VAC, convert to DC 3.8V, DC 7V, DC 12 and DC 27V, and then use it.
iDEN The up/down converter of Down Link was realized with a digital filter through conversion and A/D conversion with IF frequencies(62.5MHz) for the base station(EBTS) signals inputted through the LNA part. This picks up an excellent roll off characteristic with a digital filter, minimizes influence on other signals by intercepting other neighbor bands and signals, and is improved to remove and separate spurious waves.
iDEN 5. SYSTEM BLOCK 5.1 Block Diagram Block Diagram 5.2 Interpretation of Block Diagrams Filter is a cavity type that is connected to the donor ANT and service ANT of iDEN repeaters and has only the desired bands pass selectively among the base station(EBTS) signals and terminal signals received through antenna.
iDEN And, the Up Link takes a roll off characteristic of a SAW filter by converting RF signals at the inputted terminal to IF frequencies(70MHz) through LNA differently from the Down Link, minimizes influence on other signals by suppressing neighbor signals, and is improved to remove and separate spurious waves. PAU amplifies the iDEN signals to a proper output level with a module at the final step of wndrPrldml, pass through a filter, and then discharges it through ANT.
iDEN 6. NMS 6.1 NMS NMS is composed of RCU(RF Control Unit) and NCU(Network Control Unit) and plays a role to monitor and control the status of each module of iDEN repeater. The RCU(RF Control Unit) is connected to GUI through DEBUG port and can collect and control the status monitoring information of modules. NCU(Network Control Unit) enables the upper NMS(Ethernet) communication through the RJ45 port and can monitor and control status.
iDEN a. Turn on/off the ALC function setup through GUI. b. Compensate its difference when the forward output value is greater than the set level or less than 1dB. c. Compensate its difference when the backward output value is greater than the set level or less than 1dB. d. (２) Monitor the forward and backward output values every 1 second. References a. Forward and backward operations are independent of each other. b. It does not work during oscillation checkup. 6.3.
iDEN 6.3.3 (１) Oscillation Check functions Handling procedures a. Turn on/off the oscillation check function setting through GUI. b. Inspect the 798 ~ 799MHz section c. Measure the oscillation detection values while moving by 30KHz from the oscillation check frequency 798 ~ 799MHz. d. Find the minimum value and maximum value among the values measured in c. e.
