Real Problem 4
Users too much, channels are available in 2.4 wireless antenna are too few, most or all the channels already in use (in fact only 3-4 channels interfere with each other, the others all overlapping frequency) so that interference in the tower itself was a lot.
Stupid solution :
Users too much, channels are available in 2.4 wireless antenna are too few, most or all the channels already in use (in fact only 3-4 channels interfere with each other, the others all overlapping frequency) so that interference in the tower itself was a lot.
Stupid solution :
Some customers who complained about the link try to overcome interference by installing wireless booster!
Real Solution 4
GPS capitalize we can obtain data about: the coordinates of the location customers and the distance from the tower NOC. Then make a table of contents user: name user, the degree (if shot with a compass), distance from the tower, channels who used, the allocated bandwidth. Then we make a circular diagram, with the center of the circle the Tower, making the contours of the circle to the distance, eg 1km, 2km, 3km and so on. And by using our user and map the location of the line drawn center. Use colors to distinguish different users on line which almost coincide.
Well, from this chart we can know the density of users and signal beam. Based on this chart we can take steps to action:
Real Problem 5
One client is in trouble, from the very beginning the installation there was always a packet loss, latency big, but a good signal, but the data broken through. what the hell? because out of the way, you get the solution.
Stupid solution :
Used wireless booster pairs in the hope the problem can be resolved.
Solution Problem 5
Try to look at the client side, is there an electric field / electromagnetic big enough? whether your client with its location adjacent channel power High voltage? whether the computer monitor where your customers rock? The data will be distorted if there is good enough interference from the field electricity. let alone a radio signal, packet data through UTP cable can be damaged! Specifically for radio equipment that is placed adjacent to the electric field with high, do the following:
"Avoid building directly adjacent to the High Voltage Line"

Well, from this chart we can know the density of users and signal beam. Based on this chart we can take steps to action:
- User the same direction as, if using a PTP can be combined into one, especially if bandwith used not too large, then it can be combined in one Access Point
- Accordance no.1 if the user requires a large bandwidth and reply each PTP will continue to use channel choose a non-mutual overlapping
- Accordance no.2 if using channel overlapping each other, then use polarization antennas for different PTP minimize interference.
- User conflicting direction 180 degrees to avoid using the same channel / overlapping
- Accordance no.4 if forced to use overlapping the antenna polarization different
- Prioritize users that require large bandwidth (eg 512kbps) from interference noise channel by freeing the user to use other in the same tower.
- Combine small users in one acess point, if beamnya coincide, then use grid antenna, but if beamnya wide enough then use an antenna sectoral.

The data will be distorted if there is good enough interference from the field electricity. let alone a radio signal, packet data through UTP cable can be damaged! Specifically for radio equipment that is placed adjacent to the electric field with high, do the following:
- Grounding the tower
- Use a metal box with a good reply with grounding (connected to the tower with ground)
- If tower / box have a ground, the radio wrap with aluminum foil and connect with the body connector on your wifi radio.
- Use STP cable (no UTP) to reduce interference on the cable
- For the tower that is not ground (grounding a lightning rod, but isolated with the tower) then connect your tower to the ground. is usually tower at the shop ill-mannered grounding well. Specifically for reducing the electric field disturbance in the computer equipment in the room do the following
- Install shield on the side facing the building with a voltage power cable high. Here shield-shaped cage / bars ground to stifle electric field disturbance at the building.
- Use grounding in on roof, the function for shield also attention to open internet cafe / office based on IT technologies
