A Brief History Lesson
Geeking out over tech often requires understanding a bit of history. Let‘s quickly cover how Bluetooth and Wi-Fi technology has advanced over time.
The Story of Bluetooth
In 1989, Nils Rydbeck tasked Jaap Haartsen and Sven Mattisson – both at Ericsson in Sweden – with developing a wireless connection between mobile phones and accessories. This resulted in the first Bluetooth prototype in 1994 utilizing the 2.4 GHz frequency band.
The name "Bluetooth" comes from the Danish King Harald Blåtand (Bluetooth in English) who united warring tribes into one kingdom – just as this new wireless technology looked to unite differing industries and devices.
Fast forward to 2022, and Bluetooth 5.3 focuses on enhanced audio transmission through the Low Complexity Communication Codec (LC3). Apple‘s latest AirPods Max headphones leverage Bluetooth 5.3 for lossless sound quality.
The Evolution of Wi-Fi Standards
Wi-Fi traces origins back to 1985 when the U.S. Federal Communications Commission (FCC) opened several frequency bands for commercial use. This included the 900 MHz, 2.4 GHz, and 5.8 GHz bands that became foundational for wireless networking.
Work during the early 1990s at NCR Corporation (later renamed Lucent & Agere Systems) developed signal processing techniques leading to the first 802.11 products. The Wi-Fi Alliance brought together industry allies to brand and commercialize the technology in the late 1990s.
The latest Wi-Fi 6E standard expands available spectrum with the new 6 GHz band for improved performance. More bandwidth means faster peak connection speeds up to 10 Gbps!
Okay, now that we understand some history, let‘s unpack exactly how Bluetooth and Wi-Fi get your data flowing!
Frequency Bands: The Invisible Radio Waves
Wireless signals rely on electromagnetic radio waves to transmit data through the air. Networks and devices must agree on specific frequency bands to tune into for communication.
Bluetooth operates on the license-free 2.4 GHz frequency band. Lots of technologies from Wi-Fi to Zigbee to microwave ovens also leverage this spectrum, which can cause interference and degrade signals.
The latest Wi-Fi 6E augments existing 2.4GHz and 5GHz spectrum used by older Wi-Fi versions with the new wide-open 6GHz band. The FCC approved 1,200 MHz of airwaves for Wi-Fi usage – leading to the E designation (think Extra capacity). This essentially eliminates interference by giving Wi-Fi lots of clear channels resulting in faster, more reliable connections.
More available radio spectrum directly translates to far higher bandwidth potential when comparing Wi-Fi 6E and Bluetooth capabilities.
