Bluetooth Sulit dan Boros Daya… dan Tidak Lagi Diperlukan

While Bluetooth technology has been around for ages, it is only in the past decade that the underlying technology has advanced to the point where it has become commonplace.  From phones to cars, speakers, and more – Bluetooth is everywhere.  Its development marked a significant advancement in wireless communication, shaping how we interact with technology in our daily lives.  However, this may soon change with the development of a teknologi baru by researchers at the University of Sussex that promises to be more energy-efficient and requires a smaller footprint inside electronic devices through the use of electric field modulation.

Memahami Bluetooth

Before diving into electric field modulation and the benefits it can afford, it is important to understand what Bluetooth is, and how it works.

Apa itu Bluetooth?

Bluetooth is a wireless technology enabling the exchange of data over short distances.  It’s named after Harald Bluetooth, a 10th-century king who united Denmark and Norway, symbolizing the technology’s intent to unify communication protocols.

Ericsson (ERIC ), sebuah perusahaan telekomunikasi Swedia, memulai pengembangan Bluetooth pada tahun 1994 dalam upaya menciptakan alternatif kabel data RS-232. Baru pada tahun 1999 Bluetooth masuk ke perangkat konsumen.

Versi awal Bluetooth, seperti 1.0 dan 1.0B, memiliki masalah signifikan, termasuk kurangnya komunikasi antar perangkat. Baru dengan Bluetooth 4.0, yang dirilis pada tahun 2010, teknologi ini akhirnya memiliki kematangan untuk menjadi umum dalam elektronik sehari-hari.

Selama bertahun‑tahun, Bluetooth menjadi sangat umum di berbagai perangkat, termasuk smartphone, laptop, speaker, dan sistem mobil, untuk aktivitas seperti transfer file, streaming audio, dan sebagai sarana perangkat IoT (Internet of Things) berkomunikasi. Namun, penggunaannya mendapat kritik karena sering tidak stabil dalam hal konektivitas dan pemasangan, serta relatif boros daya dibandingkan teknologi nirkabel lain, terutama pada versi‑versi awalnya.

As technology has advanced, alternatives like Wi‑Fi Direct, NFC (Near Field Communication), and now electric field modulation have emerged, offering faster data transfer rates and more reliable connections for specific use cases.  This evolution has led to discussions about the decreasing necessity of Bluetooth in a world where more efficient and reliable wireless communication technologies are available.

Bagaimana cara kerjanya?  Modulasi Elektromagnetik

Electromagnetic modulation is a fundamental technique used in wireless communication, including Bluetooth, to transmit information over electromagnetic waves.  With regards to Bluetooth, this involves encoding digital information onto radio waves in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band.
