My 50 kilometres WiFi Adventure – Part 1
Posted by shakir as Nerd Public Journal?
I have placed orders for 4 sets of customized wireless equipments and 4 pairs of high gain antennas in hope to create a 50 kilometres WiFi link. I would like to test which setup combinations work, and if they all do, I would want to know which one works best. For each combination, I will test their performance when there's a clear line of sight between these 2 end points, when there's nLOS (near line-of-sight), and NLOS (no line-of-sight).
In order to get that 50 kilometres link, I plan to test it on an island-to-mainland connection. After some (virtual) surveying, I figure out the best end sites would be Coral Bay of Pulau Perhentian Kecil, and Pantai Sabak (my hometown, of course).
To give some ideas of how the link would be like, do take a look at these screenshots (click on satellite imagery for bigger picture);

To do the testing, people will need to be assigned at both ends to do necessary setups and antenna alignment. While things will be stationary at the Coral Bay's site, those at the mainland would be mobile; they'll be on a road trip from Kampung Raja, Terengganu to Pantai Sabak, Kelantan. The mainland's mobile team will stop at few checkpoints to test the connection at various distances, starting with 17km Coral Bay -> Kampung Raja link, If the link is a success, the team will move to another checkpoint, and test the link, till they find distance limit of the link, or reaching the final checkpoint, whichever comes first.
I have already assigned a friend to help me out at the island's end, and I'll personally be the one on the road trip. If you're interested to join the fun (and probably learn few things along the way, literally), do let me know. If you have suggestions or ideas, do voice it out, and I sure welcome handy hands shall I come into problems, say, if my ordered parts are for any reason stuck at Custom's clearance or SIRIM/MCMC's approval
The hardware components should arrive in few days time, and after Custom clearance and local testing, I'll book a hotel / chalet room at Coral Bay for the team to stay. Time shouldn't be an issue as we have 3 more weekends with 3 days holiday if Friday's holiday is taken into account (Awal Muharram, Christmas, and New Year). We could pick any of these 3, depending on hotel / chalet availability and arrival of ordered parts. The orders were actually from 3 different companies in the USA, and I can't tell for sure when will I have them all ready. If they arrive in the next 1 or 2 days, I would be more than happy to do this this very weekend
So, are you in?

wow, menarik
umpama setup VHF repeater utk amateur radio
my suggestions is
1. try guna directional antenna
2. cari view yang terbaik
3. kalau dpt guna amplifier lg bagus
