4 In the 5th morning, again we tried the 9th time. We carried some material left by the former construction of rangers' accommodation from another bank of Song-song stream among rainfall that made slippery soil. Along slippery uncertain bamboo bridge we walked carrying all material across the stream to the worksite. Then we deconstructed and relocated to another better position. The tower constructed by wooden structure, composed by planks on its besides and to set floor on its upon in order to place an 2,000 liters old water tank, followed by the two concrete columns to make balance and again used as satellite base. Some of us hung adventurously upon the structure throughout the process while the others transported all tools and materials. Satellite equipment was installed after lunch time. For security purpose, we did strengthen the structure with ropes by any certain capital or item nearby. Water leveling was still a significant order in every composition. For this time, our temporary tower reached up to 10 meters.
Then, we made connection. Our cable was exactly enough for the 10 meters tower and that made us hopeful.
There, at 10 meters height is where the test of natural barrier; 2 kilometers far away Pong Bon hill, was surrender to our strong intention and endeavor. The sky-link to target sky satellite was effective!! The noise of glad burst out in the time of happiness with all exhaustion and desperation along the 5 days swiftly faded away.
It was such a relax working atmosphere that afternoon after succession. We continued working on cable, made connection to indoor control cabinet.
Then was grounded wiring for security purpose.
After cabling and ground, we tested each function rely on standard. Those working performance and system were very effective through satellite gateway. After setting all function, we test internet accessibility, electronic mail, tune and vision, including speed of download and other resources application.
The satellite internet communication is part of iPSTAR commercial satellite service. It is a 114 watt 114 channels series FS-1300SX KU-BAND satellite with 12 years duration, produced by Space Systems/Loral (Palo Alto, USA).

Outdoor unit composes of 1.2 meters diameter, LNB at RF 12.25 - 12.75 GHz, IF 1,550 - 2,050 MHz, and 1 watt at +15V - 30V DC BUC with +10dBm RF capacity and reflector.
Indoor unit composes of control equipment; IPX 5100 terminal consumer box connected to satellite dish by RG-6 or RG-11 cable. The terminal consumer box has 2 Mbps upload and 4 Mbps download capability with USB port, RJ-45 Ethernet, Linux assess performance and support both AC and DC current.
iPSTAR is a high speed always on,Two-ways Broadband Internet which serve several kind of internet accessibility services along such Broadband Internet revolution. For example; software documentation, image, multimedia such as video on demand, e-learning, online remote meeting, voice service, broadcasting, etc.
WFCC support the satellite installation and total internet accessibility monthly service fee for Maharaja wildlife station, Thungyai Naresuan WS, objectively to increase communication channel in connection to Radio Network communication System to enhance their effectiveness on site protection and management , including to support educational research development in the future.
