Survey Location 1.Tentukan position coordinates of the location of stations, air distance of the BTS with GPS and compass
on the map 2.Perhatikan and mark the point of potential barrier (obstructure) along the path 3.Hitung SOM, and acessories path loss, EIRP, freznel zone, the height of the antenna 4.Perhatikan position to another station, the possibility of potential hidden station, over-shoot and test noise
and interference 5.Tentukan tower ideal position, elevation, length and cable alternatives if there are difficulties in the
installation 6.Rencanakan a number of alternative methods of installation, removal and tool positioning
Connector Installation
1.Kuliti coaxial cable with a cross-section, specification of minimum cable is RG 8 9913 10 db with the
calculation of losses, each 30 m 2.Jangan until there is a scratch due to excessive propagation of microwaves is on the surface of the cable 3.Pasang connector with full attention to the issue carefully and neatness 4.Solder pin edge connector carefully and neatly, make sure that does not happen short 5.Perhatikan pin installation sequence and the locks so that the cradle cable and connectors are not easily
shifted 6.Tutup connector surface with aluminum foil to prevent leakage and interference, the position must be
attached to the surface of the connector 7.Lapisi connectors with aluminum foil and coat the entire surface of the connector with isolator TBA (usually
for the installation of plumbing or electrical wiring installation home) 8.Terakhir, cover the entire surface with a rubber insulator to prevent water 9.Untuk maintenance, replace all the protective coating once every 6 months The best model is hexa 10.Konektor without solder and drat so slightly injuring the surface of the cable,
installed by using crimping tools, along with a protective rubber fuel as a substitute for rubber insulators
Making POE 1.Power over Ethernet is required to perform the injection power supply to the Wireless In A Box is
mounted on a tower, POE beneficial to reduce power losses (losses) due to the use of cables and
connectors 2.POE using 2-pair UTP cable is not used, one pair for injection + (positive) power and a pair for injection -
(negative) power, used the cable pair (a pair) to avoid loss of power due to cable loss 3.Perhatikan that the most crucial problems in the manufacture of POE is how to prevent the occurrence of
short, because the cable and power connector cross section of small and easily moved or are interested in,
tetesi with wax or gel insulator so that each point of connection is protected from short 4.Sebelum used first test all connections with a multimeter
Antenna Installation
1.Pasang pipes by the method of minimum stack to a height of 1st freznel zone passes to the nearest
obstructure 2.Perhatikan stability of the stand pipe and wire Strength, attach the stand legs to climb and Anker cows tail 3.Cek all connection cables and connectors, including the lightning rod when there are 4.Pasang antenna neatly and correctly, point by using a compass and GPS base stations corresponding locus
on the map 5.Pasang cable and trim while, not to heavy a burden connector cable and interfere with movement and
position of the antenna pointing 6.Perhatikan in installing the cable in the tower / pipeline, do not have to bend position as potential
accumulation of rain water, form such a way that is free of rain water falling down
Radio Installation Tool 1.Instal Orinoco PC Card and the right to be recognized by the OS without conflict and make sure all drivers
and utilities can work perfectly 2.Instalasi on W2K OS requires the latest drivers from the web site and in CD copy utility, although not
required PCMCIA PNP W2K drivers do precisely this conflict detection, remove it from the Device
Manager dirver 3.Instalasi on NT require austerity allocation IO address, IRQ and DMA, the BIOS better turn off all
devices (COM, LPT, etc..) And peripherals (sound card, mpeg, etc..) That are not needed 4.Semua this procedure can be completed in less than 30 minutes not including OS installation, this time more
than immediately execute the next procedure 5.Apabila persistent difficulty of installation, for the sake of efficiency while doing the installation under OS
Win98 / ME that is easier and less problems 6.Pada installation of a radio device type Wireless In A Box (Mtech, Planet, Micronet dlll.), First update the
firmware and utilities 7.Kemudian test all the existing functions (AP, Inter Building, SAI Client, SAA2, SAA Ad Hoc etc..)
Including bridging and IP Addressing using helical antenna, make sure all functions work well and stable 8.Pastikan that the Power Over Ethernet (POE) runs perfectly
Noise Testing 1.Bila all have been running normally, install all the necessary utilities and started doing the testing noise /
interference, use the default settings 2.Tanpa antenna signal Strength note whether there are caught from another station nearby, where they exist
and achieve good (around 40% - 60%) or even more, then certainly the station is operating beyond EIRP
and potentially cause interference to stations that we are constructing , consider negotiating with the
operator BTS / existing station is 3.Perhatikan what level of noise, if more than the sensitivity of the radio (usually is around - 83 dbm, read
radio specifications), for example - 100 dbm at the station point of interference is quite high, just whether
the received signal Strength can exceed the noise
Strength
4.Perhitungan signal standard is 0% - 40% poor, 40% - 60% good, 60% - 100% excellent, if the received
signal Strength is 60% but the noisenya reach 20% then the condition is poor connection (60% - 20% -
40% poor), then as far as possible the signal should reach 80% Strength 5.Koneksi poor will usually produce a PER (packet error rate - can be seen from the percentage number of
RTOs in the continuous ping) above 3% - 7% (see Planet of the utilities as well as Wave Rider), good
range between 1% - 3% and excellent under 1%, PER between the BTS and the client station must be
balanced 6.Perhitungan same station can be used to pay attention to our opponents, or BTS, in principle, signal
Strength, noise level, the PER must draw to earn the expected stability of the connection 7.Pertimbangkan alternative other scenarios when a number of the above problems can not be overcome, for
example by moving the station to another place, rotate the direction of pointing to other nearby base
stations or by the method of three point (repeater), etc..
Antenna assembly 1.Antena microwave parabolic grid type and loop yagi and have assembled because it consists of a number
of components, different types of patch panels, panel and omni directional sector 2.Rakit antenna according to the instructions (manual) and construction drawings are included 3.Kencangkan all the nuts and bolts, including connectors and particularly reflectors 4.Perhatikan that microwave antennas are very sensitive to changes in focus, then look at the assembly of the
antenna reflector to focus the best of the horn (driven antenna), a slight change will result in broad focus,
such as changes in gain (db) antenna 5.Beberapa parabolic grid type antenna has a rod extenders that can change the location of the focus of the
reflector to the horn so it can be set to gain the necessary
Antenna Pointing
General
1.Secara mounted antenna with horizontal polarization 2.Arahkan antenna in the direction indicated compass and GPS, the direction is the direction we take the
midpoint (center beam) 3.Geser antenna with a fixed direction to the right or to left center beam, one by one at each stage of the
calculation does not exceed ½ the antenna beam width specification for each side (left or right), for
example 24 db antenna, typically has a beam width 12 degree then, the maximum shift to the left or right of
center beam is 6 degrees 4.Beri mark on every change of direction and set the score, the determination of the best done by finding the
best average value, the main parameters that must be considered are signal Strength, noise and stability 5.Karena most radio devices Wireless In A Box does not have a graphical utility to represent the signal
Strength, noise, etc. (except statistics and PER) will be more practical to use the pointing device is
standard 802.11b radio that has a graphical utility such as the Orinoco, or use the Wave Rider 6.Selanjutnya if necessary adjust the antenna elevation angle in accordance with klino meter antennas at the
station opposite, calculated based on the calculation of the curvature of the earth and compare it with the
contour on a topographic map 7.Ketika best direction and elevation are estimated to have reached it if required to do the reversal
polarization from horizontal to vertical antennas for narrow beam width and increase the focus of
transmission, the second condition is a point to use the same antenna (parabolic grid) and on the second
point of the antenna polarization must same (meaning on the side opposite the antenna polarization must also be reversed into the vertical)
Testing Connection Radio 1.Lakukan test signal, similar to the noise test, it's just that at this point the antenna and cables (including
POE) is connected to a radio device 2.Sesuaikan channel and the name of the SSID (Network Name) to the identity of the BTS / AP objectives,
as well as encryption, MAC address authentication when used it on the AP must be defined first such
station MAC Address 3.Bila using Radius authentication, make sure the setting has been appropriate and try to advance the
mechanism before being installed 4.Perhatikan that most of the radio device is functioning as a bridge and worked on the introduction of the
MAC Address, IP Address that is defined thus serves as an interface based on SNMP protocol utility
only, so no need to put in the routing table 5.Tabel routing is defined on a (PC) router which is attached a radio device, for Wireless In A Box is
separate from the devices (PCs) router, then the device facing the radio device also enter an IP Address
that one subnet with the IP Address that has been defined on the radio, so that utilities are installed in the
router can identify the radio 6.Lakukan continuos ping to test the stability of the connections and know the PER 7.Bila has stabilized and the minimum Strength good signal (after deduction noise) then do the test throughput
by performing an FTP connection (with a FTP client software) to an FTP server near you (ideally at the
point of destination BTS server), the average throughput under ideal conditions will be well balanced now
download and up load, the maximum throughput on the radio 1 mbps connection is around 600 kbps and
a TCP connection with a maximum MTU 1500 can be achieved 40 kbps 8.Selanjutnya use mass download manager software that supports TCP connection simultaneously
(concurrent), do the connection to the FTP server is closest to the expectations of 5 kbps maximum
throughput per TCP connection, then it can be turned around 120 simultaneous sessions (concurrent), the
assumption 5 x 120 = 600 9.Atau with a more simple way, used on a smaller scale, with 12 concurrent connections per session trouhput
5 kbps, what the total throughput can reach 60 kbps (average)? when the connection has been achieved
then the stability can be guaranteed to be at maximum level 10.Pada each level of loading is done gradually, consider whether the RRT ping increases, the figure
approached about 100 ms was considered normal7.Orinoco PC Card, pigtail and PCI / ISA adapters 8.Multimeter, SWR, cable tester, solder, tin, wire cutting pliers 9.Peralatan climbing, harness, carabiners, webbing, cows tail, pulley10.Kunci fitting, key ring, wrench, pliers
