Evaluasi Karakteristik XBee Pro dan nRF24L01+ sebagai Transceiver Nirkabel
Abstract
ABSTRAK
Pemillihan modul transciever sebagai media transmisi data digital menjadi permasalahan bagi perancang ketika mendesain suatu sistem komunikasi nirkabel. Pada penelitian ini penulis melakukan evaluasi pada dua modul transceiver yaitu XBee Pro dan nRFf24L01+ dengan tujuan untuk menentukan modul transceiver mana yang tepat digunakan untuk kebutuhan perancangan sistem Wireless Sensor Network (WSN). Evaluasi dilakukan dengan mengirimkan data dalam bentuk karakter ASCII/ bytes secara kontinyu maupun sekuensial melalui komunikasi serial UART. Pada pengaturan untuk mode data rate 250 Kbps, XBee Pro memiliki data rate 27 Kbps dan nRF24L01+ 16 Kbps untuk protokol komunikasi serial UART. Modul nRF24L01+ lebih unggul dalam mengirimkan data secara streaming (kontinyu) dibandingkan Xbee Pro, dan nRF24L01+ memiliki Round Time Trip (RTT) tercepat 0,003 sekon sedangkan XBee Pro hanya 0,036sekon. Pada aplikasi dalam ruangan XBee Pro memiliki performa lebih tinggi karena lebih stabil dalam transmisi dengan hambatan 4 dinding sedangkan nRF24L01+ hanya 2 dinding.
Kata kunci: UART, Data Rate, Nirkabel, XBee Pro, nRF24L01+.

ABSTRACT
Chosing transciever module as a media for a digital transmission data has becoming a serious problem for a designer to design a wireless communication system. In this research, author do the evaluation for a two transceiver module that are XBee Pro and nRF24L01+, the purpose is to chose which the right transceiver module that designer need to make a Wireless Sensor Network (WSN) system. The evaluation was done by sending a data in ASCII character/ bytes as continuous and sequensial method using serial communication UART. When data rate is set to 250 Kbps mode, XBee Pro data rate is 27 Kbps and nRF24L01+ 16Kbps for serial communicaton UART purpose. nRF24L01+ is better at sending a streaming data (continuous) than XBee Pro, and also nRF24L01+ has a fastest Round Time Trip (RTT) that are 0,003 sec while XBee Pro only 0,036 sec. For indoor application XBee Pro has a better perform because it work better until 4 brick wall while nRF24L01+ only 2 brick wall.
Keyword: UART, Data Rate, Wireless, XBee Pro, nRF24L01+.
