The RF electric performance of the DB6MR20 repeater conforms to FCC requirement of the inter modulation and spurious emission. It avoids interference problems.

3.3. Electrostatic Sensitivity

CAUTION

ESD = ELECTROSTATIC DISCHARGE SENSITIVE DEVICE

Observe electrostatic precautionary procedures. Semiconduct or tra nsmitters and rece ivers prov ide highly rel iable per formance

when operated in co nformity with the intentions of their design. However, a semiconductor may be damaged by an electrostatic charge inadvertently imposed by careless handling.

Static electricity ca n be conducted to the semico nductor chip from the centre pin of the RF input connector, and through the AC connector pins. When unpacking and otherwise handling the Repeater, follow ESD precautionary procedures includin g the use of grounded wrist straps, grounded workbench surfaces, and grounded floor mats.

4.5. General

Mobile Communicatio ns Systems are planned as cellula r systems and each cell of the base station is required to provide RF coverage over a certain geographical area as per defined RF power levels. Due to the RF propagation properties, even using high radiated RF powers or complicated antenna systems, there are zones within the coverage area where the RF signal strength from base station remains inadequate for establishing the desired connectivity to mobile users.

Repeaters tradit ionally are de plo yed in the Mob ile Communication Network to fill in the “Dead Zones” caused by blocking of signals by geographic topologies such as mountains, valleys, dense foliage, high rising urban landscapes and other man-made structures. The distance from the base station also adversely affects the RF signal strength. The user views repeaters as a means to extend base stati on coverage so as to reduce the number of base stations and thereby accelerate network availability.

Repeater syste ms are installed after meticulous planning b etween BTSs and the mobile users to provide RF coverage in the shadowed regi ons. Repeater systems are available for different applications and ultimate choice shall depend on some of the factors mentioned below:

• Area to be provided with coverage.

• Indoor/outdoor coverage.

• Availability of BTSs in the vicinity.

• Antenna isolation to be achieved.

The Customer i s advised to refe r to the stick er on th e repe at er unit givin g the details of frequency bands set & the bandwidths of different sub bands equipped in the repeater.

Salient Feature s

• The repeater has been designed to meet the requirement of users

who are allocated frequency spectrum in different bands. It is provisioned to be equipped up to six s ub bands maximum in both the bands with 3+3 configuration.

• The repeater adopts duplex mode and bi-directional amplificatio n for

UL & DL signals between the base station and mobile users. It has been designed for indoor applications to meet the requirements of large number of users in the targeted area.

• It conforms to ETSI standards & international safety

requirements.

• The system can be incorporated with optional Remote

Management System (RMS). It enables status monitoring, remote

configuration & speedy maintenance.

• The system is modular in nature & can be customized to meet

requirement of user in terms of number of sub bands with the desired

bandwidth of each. The System is incorporated with monitoring facility through USB port with easy GUI interface.

• It sucks signals from the BTS through a DONOR antenna (highly

directional outdoor antenna) and distributes the signals to mobile users after amplification through a set of indoor SERVER antenna(s) (omni/ directional) system in the DL.

• In the UL, the signals from the mobile users are picked up by

SERVER antenna and retransmitted to the BTS after processing & amplification in the repeater.

The repeater consists of the following modules/units:

• LNA

• Converters

Power amplifiers Power supply unit Quad-plexers filters for transmit/receive directions Supervisory module A metallic case houses the repeater. Provision is made for heat

dissipation especially for amplifiers, which generate more heat. The choice of suitable metal as the case material gives a lightweight design with good hea t conduction. It is not waterproo f and therefore, should be installed at indoor locations only.

Figure 1: Typical In-building Coverage

5.2. Typical In-Building Coverage

The DB6MR20 repeater is designed to provide optimal coverage over an area of approximately 1,000 to 2,000 sq. meters (10,000 to 20,000 Sq ft.). However, ultimate performance depends on the obstructions blocking/absorbing o f the RF signals in si de the building and the available forward signal level at the donor antenna.

Typical coverage is usually plann ed for relatively small areas such as large conference rooms or several adjacent rooms in smaller office areas.

Coverage is primarily determined b y the available fo rward sign al level at the outdoor antenna input, loss due to the RF cable length, type of RF cable installed and achievable isolation for optimum DB6MR20 performance. Indoor coverage varies greatly due to the nature of various building construction techniques and materials. Approximations of signal level/coverage can be determined with the following assumptions:

• 10dBi to12dBi-donor antenna. Max. 9dBi indoor

omni/directional antenna.

Next Generation Sig n a l Enha ncement

• Installed total cab le and connector loss of approx imately 5 dB

(125 feet of typical 1/2” coaxial foam cable).

• Interior building s tructure consists of typical vertical stud and

drywall composition.

• Isolation between th e do nor and server antennas should be 15

dB more than the gain of the repeater.
