ABOUT

About Radio & Wire

An independent publication about IoT connectivity: which protocol fits which job, and what the specifications actually say. Launched 5 August 2026.

What we publish

Radio & Wire covers the wireless and wired protocols that connect devices to each other and to the internet: Zigbee, Z-Wave, Thread and Matter in the home; Modbus and MQTT on the factory floor; Bluetooth Low Energy in wearables; LoRaWAN, NB-IoT and LTE-M over long distances. The recurring question behind every guide is the same one an engineer faces at the start of a project: given this range, this power budget, and this data rate, what should this device actually speak?

We are not a hardware vendor, a network operator, or a certification body. We do not sell devices, connectivity, or consulting. The site exists to make the trade-offs between these standards legible to someone who has to choose one.

How the guides are researched

Primary specifications first. Figures come from the documents that define them, the IEEE 802.15.4 standard, the Bluetooth Core Specification, 3GPP release documents, the Connectivity Standards Alliance's Matter specification, LoRa Alliance regional parameters, rather than from other people's summaries of them.
Numbers carry their conditions. A range figure without a stated environment and a battery-life figure without a stated duty cycle are marketing, not engineering. Where we give a number, we say what it was measured under.
Regulatory limits are named. Duty-cycle rules in the EU 868 MHz band, dwell-time rules in the US 915 MHz band, and product-security law such as the UK PSTI Act and the EU Cyber Resilience Act constrain real deployments as much as any radio spec does.
Sources are machine-readable. Each guide carries the specifications and standards it draws on in its structured data, so the provenance of a claim is checkable without a wall of footnotes.
Pages get dated. Every guide records when it was published and when it was last revised. Standards move; Matter in particular has shipped several revisions since 2022.

Independence

As of the date on this page, Radio & Wire carries no advertising, no affiliate links, no sponsored articles, and no paid or guest placements. Nobody pays to be described favourably here, and no manufacturer has reviewed a guide before publication. If that ever changes, this section changes with it, in advance.

A full account of this domain's history

This domain has had three unrelated occupants, and anyone evaluating the site deserves the whole record rather than a discovery halfway through.

2015 to 2019 — a university trade fair. iotlinefair.com belonged to IoT Line Fair, an Internet of Things and smart-products fair organised by the EESTEC Istanbul local committee under İTÜ IEEE and held at Istanbul Technical University's Ayazağa campus, in the Süleyman Demirel Cultural Center. It ran five editions; the 2019 one took place on 26 and 27 April and is recorded in İTÜ's own news archive.

Radio & Wire has no connection whatsoever to that event. We are not its organisers, successors, or representatives, and we are not affiliated with İTÜ, EESTEC, or IEEE. We do not use the IoT Line Fair name, mark, or branding. The domain string is simply what we bought; the publication is called Radio & Wire and always has been. If the fair's organisers want this domain, our contact address is below and we will discuss it.

2022 to 2024 — machine-generated spam. After the event's registration lapsed, the domain passed to a holder who filled it with bulk auto-generated pages that had nothing to do with IoT: online casino and betting promotions, deposit-bonus and free-spins pages, payday-loan and consumer-credit pitches, dating-site pages, and essay-writing offers, published across English, Turkish, German, Spanish, Portuguese, Polish, Dutch, Greek and Arabic. Public web archives hold more than a thousand such URLs from that period. Not one of them was written or published by us, and not one of them exists on this domain today.

Since 5 August 2026 — this publication. The domain lapsed a second time and was released. We registered it fresh from the registry on 5 August 2026; the registration record shows that creation date. Everything served at iotlinefair.com since then is ours: a small, static, hand-built site with no content management system, no user-generated pages, no comment system, and no automated publishing. Every legacy URL from either previous occupant returns HTTP 404. There are no redirects to third-party sites, and every visitor and crawler receives byte-identical HTML.
