Communication between computer networks that are in separate buildings can use wireless networking technologies (wireless) local area network (LAN) as a transmission medium that is easy installation process.
However, wireless network devices are still very expensive. Wireless LAN device that already has a price reached USD 56 million. For the antenna, for example, cost about USD 2.5 million.
As an alternative, the High School of Information Management and Computer Engineering (STIKOM), Surabaya, develop the use of tin cans. This is expressed by the Head of Computer Network STIKOM Anjik Sukmaaji, Tuesday (15 / 4), at Surabaya.
Antenna tin cans
With a homemade device, the cost to create a wireless network technology can be suppressed. Tin cans that can be obtained without the cost can be used to replace the function of the antenna. While other devices are personal computers (personal computer / PC) and component devices such as wireless and cable-end connector LMR. With this technology, the total cost only $ 4 million.
Wireless network applications, according to him, can be used for Internet applications and is suitable for internet service provider (ISP) or Internet network providers. However, utilization of tin cans as a substitute for a wireless connection yet to be developed to remember jangkaunya power is still limited, which is yet to reach 500 meters.
"From the experiments we do, antenna-containing aluminum cans can be used to amplify the signal wireless devices up to a distance of 200 meters. Some of the Europeans who have experimented with this antenna can reach three to four kilometers," said Anjik. (IPS)
