The Wireless Wonder: High-Quality and Sustainable Audio

Ole Witthøft

The Evolution of Wireless Technology

Over the past three decades, the internet and wireless technology have undergone a revolution that has transformed how we experience sound, communication, and entertainment. From the early days of 14.4 kbps dial-up connections to today’s gigabit speeds and studio-quality wireless audio, we’ve entered an era where quality and sustainability go hand in hand.

The internet speed journey: From snail pace to lightning-fast streaming

In 1993, a typical internet connection via modem was limited to 14.4 kbps. Today, fiber connections offer speeds of up to 1 Gbps — an improvement of over 69,000 times. This makes it possible to stream high-resolution music and video, play online games without lag, and work in the cloud with instant responsiveness.

High-resolution music streaming: A new standard in sound

Music streaming services like Tidal and Qobuz have set new standards for audio quality. While MP3 once dominated with 128–320 kbps, these platforms now offer FLAC streaming at up to 24-bit/192kHz, equivalent to up to 9,216 kbps — nearly 30 times better than CD quality and over 70 times better than MP3 at 128 kbps.

Services like Tidal Connect and Qobuz Connect allow users to stream directly from smartphones to compatible devices — in a quality that surpasses physical media like CDs and even SACDs.

WiFi evolution: From 2 Mbps to 46 Gbps

WiFi technology has evolved dramatically since 1997, when the first standard offered just 2 Mbps. With WiFi 7, launched in 2024, maximum speed reaches 46 Gbps, enabling multiple 4K streams, real-time gaming, and high-resolution audio simultaneously.

WiSA: The wireless audio revolution

WiSA (Wireless Speaker and Audio Association) offers up to 8 channels of uncompressed 24-bit/96kHz audio (4,608 kbps per channel). This enables Dolby Atmos and surround sound wirelessly — with quality matching or exceeding traditional wired setups.

Data centers and sustainability: Streaming with responsibility

The streaming industry — with giants like Spotify, Tidal, and Netflix — is not only a driver of entertainment and culture but also a player in the global climate effort. Behind every stream lies a complex network of data centers, which have historically been energy-intensive. Today, that picture is changing rapidly. 

Spotify: Net-Zero by 2030

Spotify aims to reach net-zero CO₂ emissions by 2030, addressing Scope 3 emissions outside its direct control. In 2024, the company reported 195,027 tons of CO₂e and launched initiatives across product development, marketing, and workplaces to reduce impact. Spotify also engages users through climate-focused podcasts and projects like Sounds Right.

Tidal: Green cloud and efficiency

Tidal migrated to green cloud data centers powered by renewable energy. Using technologies like serverless pipelines and containerization, Tidal reduces energy consumption while maintaining high-quality streaming.

Netflix: Low-impact streaming

Netflix invests in energy-efficient data centers and renewable energy, collaborating with DIMPACT and the Carbon Trust to reduce streaming impact. Research shows most emiss

A future of better sound, faster networks, and smarter technology

The wireless wonder represents a vision for the future: better audio quality, faster connections, flexible solutions, and growing environmental awareness. From studio-quality streaming to wireless surround sound and carbon-neutral data centers, technology paves the way for a richer and more sustainable experience.
