Wi-Fi TVs: When They Came and How They Changed TV Watching

Today it is difficult to imagine a smart TV without a built-in Wi-Fi moduleA wireless internet connection allows you to stream videos 4K, play online games, control your TV from your phone, and even use voice assistants. But it wasn't always this way: just 20 years ago, TVs were still "dead ends," connected only to an antenna or cable. When did the turning point occur?

First experiments with network TVs began in the early 2000s, but the technology's widespread adoption occurred at the end of the decade. In this article, we'll examine When exactly did Wi-Fi TVs appear?, which models became pioneers, how wireless communication standards developed and why today no one can do without Wi-Fi Smart TVYou'll also learn how to check for Wi-Fi support on an old TV and what to do if the module is missing.

Spoiler: the first production models with Wi-Fi appeared in 2007–2008, but their capabilities were extremely limited compared to modern standards. The real boom occurred after 2012, thanks to the spread of streaming services and the release of Android TV.

The first Wi-Fi TVs: 2007–2010

Historically, the first televisions with support wireless networks appeared in In 2007They were released by companies Samsung And LG — market leaders at the time. However, these models were more like "prototypes" of modern Smart TV, than full-fledged smart devices.

So, in 2007 Samsung presented a series InfoLink (models LA55M81B And LA46M81B), which could connect to the Internet via Wi-Fi adapter (sold separately!) The functionality was limited to viewing the weather, news, and a few online videos—nothing Netflix or YouTube in its usual form. The data transfer rate did not exceed 54 Mbps (standard 802.11g), which seems funny today.

In 2008 LG released a series NetCast (models LG 42LG70 And LG 50PG60), where the Wi-Fi module was already built into some models. These TVs supported streaming from YouTube And Picasa, but the interface was extremely clunky, and video loading took minutes. Incidentally, many users weren't even aware of the Wi-Fi feature—it was buried deep in the menu.

• 📅 2007 — the first TVs with optional Wi-Fi (Samsung InfoLink).
• 📡 2008 - built-in Wi-Fi in the series LG NetCast (but only in top models).
• 🐢 Speed — to 54 Mbps (standard 802.11g).
• 💰 Price — Wi-Fi adapters were sold separately for $50–$100.

⚠️ Attention: If you have a TV from 2007-2010 with Wi-Fi, it most likely only supports the outdated standard. 802.11gThis means that the speed will be lower than that of modern routers, and some functions (for example, 5 GHz) may not work.

Breakthrough 2010–2012: the emergence of Smart TV and the 802.11n standard

The real revolution took place in 2010–2012, when manufacturers began to implement it en masse Smart TV platforms and updated standard 802.11nThis standard allowed the speed to be increased to 300–450 Mbps and improve connection stability.

In 2010 Samsung released a series Smart TV 7000 (models UN55C7000, UN46C7000), where Wi-Fi became a standard option even in the mid-price segment. These TVs supported:

• 🎬 Streaming Netflix, Hulu, YouTube V 720p.
• 🎮 Online games through Samsung Apps (analogue of the app store).
• 📱 Remote control from a smartphone (app) Samsung Remote).

In 2011 LG responded with a series Smart TV LW6500 with support Skype (a separate webcam was needed) and 3D content. And in 2012 Sony released Bravia HX850 — the first TV with support Wi-Fi Direct, which allowed you to connect to other devices without a router.

Important: it was during this period that the first ones appeared hybrid TVs, which could work with both cable and wireless internet. However, many models still required the purchase of a separate Wi-Fi dongle to connect to networks 5 GHz.

The 4K and 802.11ac Era: 2013–2016

With the advent of 4K content (permission 3840×2160) Wi-Fi speed requirements have increased dramatically. The old standard 802.11n It was no longer able to handle high-quality video transmission without lag. The solution came in the form of 802.11ac (Wi-Fi 5), which supported speeds up to 1.3 Gbps and work in the range 5 GHz.

IN In 2013 Samsung released a series F8000 — the first televisions with 802.11ac and support 4K streamingThey could play videos from YouTube And Amazon Prime in Ultra HD, but only with a stable connection. Incidentally, it was during this period that manufacturers began to abandon Wi-Fi dongles — the module began to be built into all mid- and high-end models.

In 2014 LG presented WebOS TV (models LB6500, EC9300), where Wi-Fi was used not only for streaming, but also for:

• 🎤 Voice control (via remote control Magic Remote).
• 📱 Miracast (wireless screen broadcasting from your phone).
• 🔄 Automatic software updates.

And in 2015 Sony released Android TV (series Bravia X900C), where Wi-Fi became a key element of the ecosystem. Now the TV could install apps from Google Play, synchronize with Google Assistant and even play Android games with a gamepad.

Why did 4K require a new Wi-Fi standard?

Streaming 4K video requires a minimum speed of 25 Mbps (for compressed content) and up to 100 Mbps for uncompressed content. The 802.11n standard could theoretically provide 300 Mbps, but in practice, speeds dropped to 50–100 Mbps due to interference and distance. 802.11ac solved this problem by:

- use of the 5 GHz range (less interference);

- MU-MIMO technologies (simultaneous operation with several devices);

- increased channel width (up to 160 MHz).

Current standards: Wi-Fi 6 and 6E (2017–2026)

The latest major update was the standard Wi-Fi 6 (802.11ax), which began to be implemented in televisions with 2019He suggests:

• ⚡ Speed ​​up to 9.6 Gbps (theoretically).
• 📶 Better performance in interference conditions (technology OFDMA).
• 🔋 Lower power consumption.

The first televisions with Wi-Fi 6 steel:

• 📺 Samsung Q950TS (2020) - flagship with support 8K And Bixby.
• 📺 LG OLED CX (2020) - gaming TV with HDMI 2.1 And NVIDIA G-Sync.
• 📺 Sony X900H (2020) - optimized for PlayStation 5.

In 2021–2026 Wi-Fi 6E (extended version with range support 6 GHz) began to appear in premium models, for example, in Samsung QN900C (2023). However, for most users, the difference between Wi-Fi 5 And Wi-Fi 6 It's not obvious on TV unless you're streaming. 8K or don't use your TV as a gaming monitor.

⚠️ Attention: If your router does not support Wi-Fi 6Purchasing a TV with this module will not provide any speed increase. Please check your equipment's compatibility before upgrading.
