Abstract


Di era konektivitas nirkabel yang semakin maju, gangguan antara perangkat Bluetooth dan Wireless LAN (WLAN) pada rentang frekuensi 2,4 GHz telah muncul sebagai tantangan kritis. Penelitian kami menggali aspek spesifik tentang bagaimana gangguan dari perangkat Bluetooth yang umum digunakan berdampak pada kinerja WLAN pada frekuensi yang sama. Dalam konteks ini, kami melakukan penyelidikan mendalam tentang dampak gangguan Bluetooth pada waktu transmisi dan throughput WLAN. Temuan eksperimental kami mengungkapkan implikasi yang signifikan. Pada jarak 1 meter antara perangkat Bluetooth dan WLAN, transmisi file JPEG mengalami pengurangan waktu transmisi sebesar 7,53% dan throughput sebesar 5,52%. Demikian juga, transmisi file MP3 mengalami penurunan waktu transmisi sebesar 12,35% dan throughput sebesar 9,98%. Dalam kasus file AVI, pengurangannya bahkan lebih jelas, menghasilkan penurunan waktu transmisi sebesar 21,32% dan penurunan throughput sebesar 16,01%. Hasil ini menggarisbawahi perlunya peningkatan kesadaran dan strategi mitigasi mengenai gangguan Bluetooth dalam skenario koeksistensi WLAN. Implikasi dari penelitian kami bergema secara signifikan untuk perancang dan administrator jaringan nirkabel, menawarkan wawasan untuk memastikan kinerja jaringan yang konsisten dan kuat.

ABSTRACT

In the era of advanced wireless connectivity, interference between Bluetooth devices and Wireless LANs (WLANs) in the 2.4 GHz frequency range has emerged as a critical challenge. Our research delves into the specific aspects of how interference from commonly used Bluetooth devices impacts the performance of WLANs at the same frequency. In this context, we conduct an in-depth investigation of the impact of Bluetooth interference on the transmission time and throughput of WLANs. Our experimental findings reveal significant implications. At a distance of 1 meter between the Bluetooth device and the WLAN, JPEG file transmission experiences a reduction in transmission time by 7.53% and throughput by 5.52%. Likewise, MP3 file transmission experienced a reduction in transmission time by 12.35% and throughput by 9.98%. In the case of AVI files, the reduction is even more pronounced, resulting in a 21.32% decrease in transmission time and a 16.01% decrease in throughput. These results underscore the need for increased awareness and mitigation strategies regarding Bluetooth interference in WLAN coexistence scenarios. The implications of our study resonate significantly for wireless network designers and administrators, offering insights to ensure consistent and robust network performance. .
