<![CDATA[Development of a local area network (LAN) needs a network cable such as UTP twisted pair especially for connecting hardware like personal computer with CCTV. The connection should be on the basis of IP address which is connected with switch, and then the data eventually is sent to server. Generally, in the field, a hardware network has two main connection; first, connections to electricity for switching on the software by using an electricity cable which is suitable to the need of electrical capacity; second, connection to UTP twisted network for sending the data to the server. This process can be simplified by using network cable both for sending the data to server and for electrical pathway. Some pairs of network cable which are not used for sending data to server can be occupied to convey electrical wave to switch on and to operate the hardware. In order to use network cable for multiple purposes, it needs electrical configuration such as power of ethernet (PoE). The PoE is a system to utilize the UTP twisted pair cable to transmit unoccupied power for electrical pathway so that it can increase the efficiency of system.]]>

<![CDATA[Someone sometimes forgets to put their belongings so that they leave them somewhere, it will pose a risk of losing their belongings. To solve this problem, a reminder is needed so that it is expected to minimize the risk of loss. This device implements point-to-point communication from the Bluetooth Low Energy AT-09 transmitter module with Arduino Nano and the receiver module with an Android smartphone. This reminder device will activate an alarm on the Android smartphone application when the two modules are more than 5 meters away. The measured distance is converted from the Received Signal Strength Indicator (RSSI) value received by the smartphone which is affected by obstructions, packet loss, and delay. Based on the test results, at a distance of 5 meters, the system can be connected and work properly, in unobstructed conditions (Line of Sight) or obstructed conditions (Non-Line of Sight). In the blocked condition, it has a packet loss of 1.1% to 4.4%, the received signal strength (RSSI) has decreased the value to a difference of -8 dBm, and the delay time is 2 seconds.]]>

<![CDATA[Femtocell has been considered as an important technology to increase the cellular system capacity by bringing the base station closer to the user and shrinking the cell dimension. Basically, femtocell networks are deployed in indoor environment such as an office. Thus, femtocell placement problems are one of the important issues in planning the wireless networks, since the manual planning processes are not efficient. In this paper, the solution of femtocell placement problem in an indoor environment is solved by bat algorithm. Selecting the best position of the femtocell is the main objective so the capacity can be maximized. In a 100 trial study, the SNR can be optimized up to 34.89 dB. In conclusion, the bat algorithm is able to improve the SNR efficiently and effectively.]]>
