When choosing a new TV, it's easy to get confused by the abundance of abbreviations and technical terms on the box or in the model description. Especially if you need a device that supports Internet and wireless connectionManufacturers use different ways to indicate these functions, from direct inscriptions Smart TV And Wi-Fi down to the letters and numbers encrypted in the model. In this article, we'll examine all possible markings so you can confidently distinguish a smart TV from a regular one before purchasing.
It is important to understand that the presence Wi-Fi module and support Internet functions — these aren't always the same thing. Some models can only connect to the network via a cable, while others have a built-in browser but don't support streaming services. We'll teach you how to "read between the lines" in technical specifications and avoid common mistakes when choosing.
You will also learn how to check the real capabilities of a TV by its article number or serial number, which chips hide behind abbreviations like DLNA or Miracast, and why is it sometimes a cheap model with markings Wi-Fi Ready costs more than a full-fledged one Smart TV.
1. Basic abbreviations: what do Smart TV, Wi-Fi, and other terms mean?
Let's start with basic definitions, essential for understanding product labeling. You'll find these terms on the box, in the product description, or in technical specifications:
- 📺 Smart TV — a TV with an operating system (Android TV, webOS, Tizen, etc.) that supports the installation of applications, Internet access, and content streaming. Not all Smart TVs have built-in Wi-Fi!
- 📶 Wi-Fi (Built-in Wi-Fi, Wireless LAN) — a built-in module for wireless internet connection. Can operate in the following standards
802.11a/b/g/n/ac/ax(the newer the standard, the higher the speed). - 🌐 Ethernet (LAN) — a connector for connecting an internet cable. It's even found on non-smart TVs for firmware updates or IP-TV.
- 🔄 Wi-Fi Direct — a technology for direct connection between devices (for example, for broadcasting a smartphone screen without a router).
- 🖥️ DLNA — support for streaming media files from other devices on the local network (for example, movies from a computer).
- 📱 Miracast / AirPlay — standards for wireless screen sharing from a phone or tablet (analogous to Screen Mirroring).
Please note: If the specifications only indicate Wi-Fi Ready, this means that the TV does not have a built-in Wi-Fi module, but supports connecting an external adapter (usually via USB). This option is cheaper, but requires purchasing an additional device.
⚠️ Please note: Some manufacturers (eg. Xiaomi or TCL) may indicate letters in the model name Pro or Plus, implying advanced features, including Wi-Fi. However, this isn't a rule—always check the specifications!
2. How to recognize a Smart TV by its model name: decoding the letter codes
Many brands encrypt key features of a TV into its article number or serial numberBy understanding the logic behind the designations, you can identify Wi-Fi and Smart TV capabilities even before checking the specifications. Here's how it works for popular manufacturers:
| Brand | Example of a model | What does it mean? | Smart TV / Wi-Fi |
|---|---|---|---|
| Samsung | UE55TU8500UXRU |
U — Ultra HD, TU — 2020 series, 8500 - model, UX — for Europe |
All models of the series TU and newer (2020+) - Smart TV with Wi-Fi. In series NU (2018–2019) Wi-Fi is only available in models numbered above 7000. |
| LG | 55UN73006LB |
UN — LED backlight, 7300 - model, 6L - for Europe, B — 2021 |
Models with NanoCell or a number above 7100 - Smart TV with Wi-Fi. Series UK (For example, UK6200) - without Smart functions. |
| Sony | KD-55X80J |
KD — LED panel, 55 — diagonal, X80 — series, J — 2021 |
All models with a series letter X (For example, X80, X90) — Smart TV with Wi-Fi. Series W or R may be without Wi-Fi. |
| Xiaomi | Mi TV P1 55 |
P1 — series, 55 — diagonal |
All modern models (Mi TV A2, P1, Q2) - Smart TV with Wi-Fi 5 (802.11ac). |
In Samsung and LG models, the key indicator of a Smart TV is the series letter (for example, TU for Samsung or UN for LG). If the series is older than 2018 (for example, MU for Samsung), Wi-Fi may not be available even on top-end models.
U Philips And TCL the logic is different: for example, Philips models with a prefix The One (For example, 58PUS8506/62) always have Smart TV and Wi-Fi, and TCL series C (For example, 55C715) - budget ones without Wi-Fi, and series P or Q — with a full range of functions.
How to check if your model supports Wi-Fi
3. Where to look for information about Wi-Fi and Smart TV: 5 reliable sources
If decoding the model name does not provide a clear answer, use these verification methods:
- Official website of the manufacturer. Enter the model number in the search on the brand's website (for example,
support.samsung.comorlg.com/ru/support). Search sections Specifications or Technical specifications. - Documentation in the box. Comes with the TV Quick Start Guide or Spec Sheet — network capabilities are always listed there. Look for the items
Wireless LANorSmart Features. - Sticker on the back panel. There may be a sticker with logos on the TV case (usually near the ports) Wi-Fi Alliance (📶) or Smart TV (📺+🌐).
- Settings menu. If you have already purchased the TV, go to
Settings → NetworkAvailability of pointsWi-FiorWireless networkmodule confirmation. - Product comparison services. On Yandex.Market, Google Shopping or NSK Enter the model and study the block CharacteristicsPay attention to the year of manufacture—data on older models may be inaccurate.
Be careful with store descriptions! Some sellers indicate Smart TV The title says so, but the specifications show that Wi-Fi is missing. Always check the part number.
⚠️ Attention: There are counterfeits of famous brands on the market (for example, "Samsung-like" or "LG-style"). These TVs may have the Smart TV logo on the box, but they actually run a stripped-down firmware without app support. Buy only from authorized dealers!
How to distinguish an original from a fake?
1. Check the serial number on the manufacturer's website (for example, through the Samsung Check Coverage service).
2. Original models have a hologram on the box and a sticker with a QR code leading to the official website.
3. The original Smart TV menu always has a section with firmware information (for example, Settings → Support → About TV), where the OS name is indicated (Tizen, webOS, etc.).
4. Technical characteristics: what to look for when choosing
Even if a TV supports Wi-Fi and Smart TV, its capabilities can vary greatly. Here are the key parameters to check:
- 🔗 Wi-Fi standard:
802.11n(Wi-Fi 4) - speed up to 150-300 Mbps. Suitable for watching videos inFull HD, but it may slow down when4K.802.11ac(Wi-Fi 5) — speeds up to 866–1300 Mbps. Optimal for streaming4K HDR.802.11ax(Wi-Fi 6) - speed up to 2400 Mbps. Needed for8Kor multi-user networks.
- 🖥️ Operating system:
- Android TV (Sony, Philips, Xiaomi) - maximum compatibility with applications, but may slow down on weak hardware.
- Tizen (Samsung) - Optimized for streaming, but limited app selection.
- webOS (LG) - intuitive interface, but weak support for third-party services.
- Roku TV (TCL, Hisense) - simple interface, but few settings for experienced users.
- 🔄 Streaming service support: Check if they are installed by default Netflix, YouTube, Kinopoisk, IVI etc. Some brands (for example, Samsung) block third-party applications on their operating systems.
- 🔌 Ports and interfaces: For a stable internet connection, you will need a connector.
Ethernet (LAN)If you plan to connect external devices, check the availabilityHDMI 2.1(For4K@120Hz) AndUSB 3.0.
Pay special attention memory capacity: for smooth operation of Smart TV you need at least 8 GB built-in memory and 1.5–2 GB operational. Budget models (for example, TCL 4-series) often have only 4 GB memory, which leads to lags when installing applications.
5. Marketers' traps: how to avoid buying a "pseudo-smart TV"
Manufacturers and retailers sometimes use marketing ploys to pass off a regular TV as a "smart" one. Here are the most common ones:
- 🎭 "Smart functions" without Wi-Fi. The description may indicate "Smart TV", but internet connection is only possible via cable. Example: some models Thomson or Dexp.
- 🔌 "Wi-Fi Ready" instead of "Wi-Fi Built-in". As we mentioned earlier, Ready This means you need an external adapter. Its price (1,500–3,000 rubles) may make it less cost-effective than a full-featured Smart TV.
- 📱 Supports Screen Mirroring only. Some TVs (for example, budget ones) Hisense) can receive images from a phone via Miracast, but do not have their own Smart TV interface or browser.
- 🌐 Outdated OS. TVs with Android 5–7 (for example, old ones Philips or Sharp) are technically Smart TVs, but they do not support modern applications.
- 🔄 Subscription to services included. Some sellers offer "free" Netflix for a year", but the TV cannot install other applications.
To avoid disappointment, always check:
- Is it in the TV menu?
App StoreorLG Content Store(for installing applications). - Are modern video codecs supported?
H.265/HEVC,VP9) for viewing4K. - Is it possible to update the firmware via the Internet (item
