Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.

Synchronization is the process of setting the course of several processes at the same time. Synchronization builds upon students' academic value table STTA Yogyakarta by comparing records for the records in the database. If there is a difference in the academic value of the table the different values will be returned as the value of the original with comparing by using the master database. Record based table synchronization is expected to address the security system on the database and provide security guarantees a safe and comfortable.Authentication is a process by which a user is identified by the server before the user using the network. In the process, the user is requesting access rights to the server to use a network. Authorization is the allocation of what services are entitled to be accessed by the user on the network. Authorization is done when the user has been declared eligible to use the network. Accounting is a process performed by the server to record all user activity in the network, such as when the user starts using the network, end user when the connection to the network, how long the user using the network, how much data is accessed from the network user.The results of the implementation of synchronization using a table based record system security authentication, authorization, accounting changes that may prevent the occurrence of data in a database, optimizing the use of stored, and enhance security systems at the database STTA center of Yogyakarta.
