Safety Precautions,
in the
following section, for proper antenna selection and installation
A pre-installation survey should be performed prior to commitment to installation. Measurement of Received Signal Strength Indication (RSSI) should be recorded throughout the building in all areas w her e c ell phone co vera ge is desired. RSSI le vels aro und t he exterior of the building as wel l as on the roof to p o r a s c los e t o t he poi nt w her e the e xter i or ant enna w i ll be ins t al led s ho uld a lso be r ec or d ed.

The exact location of the proposed outside antenna should be measured with a GPS unit and t he coo r dinates of the ce ll si tes c losest to t he buildi ng in whic h t he system is being i nstalled sho uld be obta i ned. Wit h these coordinate s the dis tance and beari ng to eac h of the loca l ce ll si tes ca n be compute d a nd made av ai lable to the installatio n team. The first choice should be the closest site unless there is blockage in the form of buildings or terrain betwee n the building and t his cell site. If blocka ge exis ts an alter nate site ma y be avai lable.
If GPS coor di nate s are not avai lable there is an alte r native me thod of loca ting the domi nant si te : connec t a handse t via SMA female to N ma le adapter to the directi o nal donor ante nna. Rota te t he antenna unti l maxim um RS SI and S QE readings are obtained and secure it.

It is im por tant to locate the IBA at a central location and try to keep the coax runs from the amplifier to th e antennas as short as possible. A maximum length of 150 feet is suggested although longer runs might be accommodated. This as sumes that a coax with loss at

800 MHz of approxim at e ly 3.5 dB per 100 feet is use d. The coax use d s hould be a nominal RG-8 type with a flame retardant rating except when installed in space where moving air (heating and/or cooling) exists. In which case the coax must be “ple num” ra te d. For long r uns that exceed 150 fee t, the use of low los s ½” coax is desirable. Of primar y concer n is the iso latio n between the outside antenna and t he inside antennas.
Important note: A high degree of isolation must be afforded in order to prevent any re-gene rat ive feedb ack in t he system. Fe edb ack of this na t ure cause s t he amplifier t o emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal operation of the cell site. This isolation should be in the order of 70 dB and is usually obtained by m ounting the outside antenna away from the edges of the roof. The use of window mounts or other non-rooftop mountings should be avoided.
SAFETY PRECAUTIONS
!!!!
For IND OOR u se, an Omni-Di rectional Antenna with a maximu m g ain of 3dBi is authorized for use with this unit. Inside antennas must be positioned to observ e minimu m separation of 20 cm. (~ 8 in.) from all us e r s and bystand ers. For the p rotection of per sonn el w or ki ng in the vicinity of inside (downlink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observe d .
The installation of an INDOOR antenna must be such that, under normal conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure that the employee or bystander does not receive RF-exposure beyond the Maximum Permissible Exposure according to section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.

!!!!
For OUTDOOR use, a Directional Antenna up to a maximum gain of 11dBd is authorized for use with this unit. The Outside antenna must be positioned to observe minimum separation of 120 cm. (~ 4 ft.) from all users and bys tan ders. For the prot ection of personnel working in the vicinity of outside (uplink) antenna s, the following guidelin es fo r minimum distances between the human body and the antenna must be observe d .
The installation of an OUTDOOR antenna must be such that, under normal conditions, all personnel cannot come within 120 cm. (~ 4 ft.) from the ou tside anten na. In all in stallati ons, th e antenna sh ould never be mounted such that the main beam is directed toward an area where workers or bystanders may be present. Exceeding this minimum separation will ensu re that the w orker o r byst and er do es no t receive RF -expo sure b eyon d the M aximu m Permissib le Expo sure accordi ng to sectio n 1. 1310 i. e. limi ts for General Population/Uncontrolled Exposure.
Physical Installation
The coaxial cable discussed above should be pulled from the roof top location to the space designated f or the ampl ifier in stallation. Add itional coax should be pull ed from the amplifier to where power spl itters are located and thus to the position designated for the Omni-direction al antennas. Usually this is accomplished by using existing cableways and running the cable above suspended ceilings. In many cases the Omni-directional antennas can be located above the suspended ceil ings however, when this is not poss ible, alt ernatives such as c eil ing or wall m ounted ant ennas may be use d.
When mounting the amplifier, take care to avoid areas of high heat or extreme cold. In g eneral, do n ot place the unit on or n ear the top of high ceilings, by heaters or in col d stor age areas.

In most cases th e IB A will need very little adjus tment. Aft er connecting the coax and poweri ng up the IBA, t he si gnal leve ls within t he previously surveye d areas should be checked for adequate RSSI and Signal Quality Equivalent (SQE) levels. Measurements should be made at the perimeter of the building both inside and outsid e. It is imp ortant th at th e RSS I level s measured outsid e th e building re main close to those measured prior to installation of the IBA.
Both the uplink and downlink overload indicators should remain off. If either indicator is illuminated, the gain of the appropriate link should be reduced.
If the gain of the amplifier needs adjustment the uplink and the downlink may be adjusted by means of the step attenuators on the rear of the unit. Attenuation from 0 dB to 28 dB in steps of 4 dB m ay b e ins er ted by pr oper sel ection of the 4, 8 an d 16 dB attenuat ors. If satisfactory cell (or two-way) phon e performance is n ot obtained wh en the phon e is in cl ose pr oxi m ity t o th e int er ior an t enn a it may b e n ec ess ary t o decrease the gain of one or both of the links.

TROUBLESHOOTING
All external cables should be carefully checked for “ sh orts” and “opens”. The rooft op anten na, if directional, s hould be ch ecked fo r pr oper alignm ent al ong the
cal culated comp ass heading. Typically, the d irecti onal antenn a should be aimed at th e sam e sigh t t h at you r han d s et us es in th e ar e a wh er e t he ou t s id e an t en n a is to be placed.
If cab le s an d al ign m en t a r e O. K. it m ay be n ec e ss ar y to use a spec t ru m an al y z er t o examine the signal environment in which the IBA is operating. The existence of strong analog signals within the frequency b ands can cause problems particularly on the downlink. In some cases additional filtering might be required to reject these unwanted signals. Automatic Gain Control (AGC) may be switched on by moving the leftmost dip switch to the on (down) position. In some instances the directional outsid e antenna c an be reoriented, horizontally to place th e interfering s ource in an ant en na pat te rn “n ull ”. Th er e als o ma y b e so me c as es wher e th e int erf er enc e fr om outside sign als is so great that they can not b e filtered or otherwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may not be practi ca l to use the IBA fo r provi ding cov era ge at t hese sites .
