Planet Survey Location 1. Determine the coordinates of the position of station location, distance air
of base stations with GPS and compass on the map 2. Note and mark the point of potential barrier (obstacle)
along the path 3. Calculate the SOM, the path and acessories loss, EIRP, freznel zone,
antenna height 4. Note the position of another station, the possibility of potential
hidden station, over-shoot and test noise and interference.
Calculated multipath signal and the cross section
signal from another station 5. Determine the ideal position of the tower, elevation, length and cable
alternative if there are difficulties in the installation 6. Plan a number of alternative methods of installation,
transfer of positions and equipment. Connector Installation 1. Skinned coaxial cable with cross-sections,
specification of minimum cable is RG 8 9913 or CNT400
with the calculation of losses, 10 dB per 30 m 2. Do not let happen due to excessive scratching
microwave propagation is on the surface of the cable 3. Attach the connector carefully and fully consider
neatness problem 4. Solder pin edge connector carefully and neatly, make sure
not occur short 5. Notice the order of mounting pins and locks so that
cable and connector holder are not easily shifted. Test
possible short with a multimeter 6. Cover the surface of the connector with aluminum foil to
prevent leakage and interference, the position must
attached to the surface connector 7. Cover connectors with aluminum foil and cover the entire
connector connection insulators surface with TBA (ordinary
for installation of plumbing or electrical cable installation
home), or isolation of 3 M. Cover well with silicon gel 8. Cover the entire surface with rubber insulators to burn
prevent water 9. For treatment, replace all the protective layer of 6
months 10. The best connector is a model hexa (crimp) without solderan
and drat (screw) so slightly injuring the surface of the cable,
installed with crimping tools, along with rubber fuel
as a substitute protective rubber insulators. Making POE This is only optional, if now a lot of the Access Point that already use the POE. So it's a package with its Accas Point. 1. Power over Ethernet is required to perform injection supply
power to the device Wireless In A Box is mounted on top
tower, POE useful to reduce power losses (losses)
due to the use of cables and connectors 2. POE uses 2 pair UTP cable that is not used, 1
pair for injection + (positive) power and 1 pair for injection -
(Negative) power, used pair cable (pair) for
avoid a decrease in power due to cable loss and use
adapter with power (Ampere) is greater than the standard
default device to be able to achieve damping
over UTP cable 3. Note that the most crucial problems in
POE-making is how to prevent
occurrence of short, because the cable and power connector
cross section was small and easily moved or are interested,
used as drops of wax or insulator (silicone) gel for every point
connection is protected from short 4. Before the first test used all the connections
with a multimeter. Antenna Installation We briefly discuss the installation by using the triangle tower. 1. Climbing tower reached a height that the need
(Minimum 1st freznel zone passes to the obstacle
nearest). Before climbing the completeness check tool
required for installation on top of tower, do not there
left behind, because it would trouble themselves as well as
others. Other equipment such as grid, AP radio, pipe
iron (handlebar) can be taken directly or in drag
using a rope. 4. Put the antenna in an iron pipe, point by using
compass and GPS as the locus of BTS on the map 5. Attach the cable to the AP Radio that have been included in
Boxes, trim while, not to be heavy cable

by the OS without conflict and make sure all drivers and utilities
can work perfectly 2. Installing on OS w2k require the latest drivers from the web
site and in CD copy utility, no drivers required
PNP PCMCIA though w2k do precisely detection
This raises the conflict, remove it from Device Manager dirver 3. Installation 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. All these procedures can be completed in less than 30 minutes not including the installation of the OS, more than this time immediately execute the next procedure 5. If the persistent difficulty of installation, for the time being for the sake of efficiency to do the installation under OS Win98 / ME which is easier and less problem 6. In the installation of a radio device type Wireless In A Box (Mtech, Planet, Micronet dlll.), First update the firmware and utilities 7. Then 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. Ensure that your Power Over Ethernet (POE) runs perfectly. Noise Testing 1. When all has been running normally, install all the necessary utilities and started doing the testing noise / interference, use the default settings 2. Without notice if there is an antenna signal strength is caught from another station nearby, where they exist and achieve good (about 40% - 60%) or even more, then certainly the station operates exceed EIRP and potentially cause interference to the station that we are constructing, consider to negotiate with the operators of BTS / station these existing 3. Notice how the 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 high, stay whether the received signal strength can exceed the noise 4. Calculation of the standard signal strength is 0% - 40% poor, 40% - 60% good, 60% - 100% excellent, if a 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 strength should reach 80% 5. Poor connection will usually result in PER (packet error rate - can be seen from the percentage number of RTOs in the continuous ping) over 3% - 7% (as seen from utilities as well as Wave Rider Planet), good range from 1% - 3% and 1% excellent, below , PER between the base station and client station must be balanced 6. The same calculation can be used to pay attention to the opponent or BTS station we are, in principle, signal strength, noise level, PER must be balanced to obtain the expected stability of the connection 7. Consider another scenario alternatives when a number of problems above 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 using 3 points (repeater), etc.. Antenna assembly 1. Microwave antenna grid parabolic type and loop and Yagi need to be assembled because it consists of a number of components, different types of patch panels, panel and omni-directional sector 2. Raft antenna according to the instructions (manual) and construction drawings included 3. Tighten all nuts and bolts including connectors and in particular reflector 4. Note that the microwave antenna is very sensitive to changes in focus, then during assembly of the antenna look their best on the horn reflector focus (driven antenna), little change will result in broad focus, such as changes in gain (db) antenna 5. Several types of grid parabolic antennas have a stem extender that can change the location of the focus of a reflector on the horn so that it can set the required gain. Antenna Pointing 1. In general, an antenna mounted with horizontal polarization 2. Point the antenna in the direction indicated compass and GPS, this way we consider the midpoint of the (center beam) 3. Slide the antenna with a fixed direction to the right or to left center beam, one by one at every stage of the calculation does not exceed ½ specification antenna beam width for each side (left or right), say 24 db antenna, typically has a beam width 12 degrees then , the maximum shift to the left or right center beam is 6 degrees 4. Give a sign at each change of direction and set score, determining the best direction done by finding the average value of the best, the main parameters that must be considered is the signal strength, noise and stability 5. Since most radio devices Wireless In A Box does not have a graphical utility to represent the signal strength, noise, etc. (except statistics and PER), then to make it more practical to use a pointing device is standard 802.11b radio that has a graphical utility such as the Orinoco, or use the Wave Rider 6. Furthermore, if necessary adjust the antenna elevation angle in accordance with klino meter antenna at the station opposite, calculate based on the calculation of the curvature of the earth and compare it with the contours on topographic maps 7. When the direction and elevation are estimated to have achieved the best it can be done if necessary polarization reversal from horizontal to vertical antennas for narrow beam width and increase the focus of transmission, the second condition points to use the same antenna (parabolic grid) and the second point must be the same antenna polarization ( means on the side opposite the antenna polarization must also be reversed to be vertical) Testing Connection Radio 1. Perform the test signal, similar to the noise test, only on the current antenna and cables (including POE) has been linked to a radio device 2. Adjust the channel and the name of the SSID (Network Name) to the identity of the BTS / AP objectives, as well as encryption, MAC address authentication if used then the AP must be defined first MAC address of the station 3. When using Radius authentication, make sure the settings are in compliance and try first before reinstalling the mechanism 4. Note that most of the radio device is to act as a bridge and work on the introduction of the MAC Address, IP Address that is defined so that functions as an interface utility based on SNMP protocol only, so do not need to be incorporated into the routing table 5. Routing table is defined in (PC) router where radio devices mounted, for Wireless In A Box, which is separate from the devices (PCs), routers, then the device facing the radio device also enter an IP Address that one subnet with the IP Address that has been defined in radio devices, so that utility is installed in the router to recognize the radio 6. Do Continuos ping to test the stability of the connection and knowing PER 7. When you have been stable and good minimum signal strength (after deducting the noise) then do the test throughput by performing an FTP connection (with a FTP client software) to the FTP server near you (ideally at the server point of destination BTS), average throughput under ideal conditions will be better balanced when downloading 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. Next use a mass software download manager that supports TCP connection simultaneously (concurrent), do the connection to the FTP server near you with the hope of 5 kbps maximum throughput per TCP connection, it can be turned around 120 simultaneous sessions (concurrent), the assumption is 5 x 120 = 600 9. Or in simpler ways, used on a smaller scale, 12 concurrent connection with trouhput per session 5 kbps, what is the total throughput can reach 60 kbps
(Average)? if achieved, the stability of the connection has to
