Literal j.1 of Resolution 1985
Thread operates on the 2.4 GHz ISM band using the IEEE 802.15.4 standard (the same physical layer as Zigbee) and falls under literal j.1 of Resolution 1985 — the same literal as WiFi, Bluetooth, and Zigbee. The O-QPSK modulation with DSSS at 250 kbps meets the spread-spectrum requirement of literal j.1. For SUBTEL, Thread and Zigbee are regulatorily equivalent: same radio, same literal, same obligation. The difference lies in the network layers (native IPv6 in Thread vs proprietary protocol in Zigbee), which SUBTEL does not regulate.
Thread is an IPv6 mesh protocol created by the Thread Group (founded in 2014 by ARM, Samsung, Nest/Google, Freescale, Silicon Labs, and Yale). Unlike Zigbee, which depends on a central coordinator, Thread forms a self-healing mesh network where any router can assume the leader role if the current one fails. Every Thread device gets a unique IPv6 address thanks to 6LoWPAN (IPv6 header compression), enabling end-to-end communication with standard internet protocols. The network supports 250+ devices per partition, with Sleepy End Devices that can run for years on a CR2032 battery.
A Thread Border Router (TBR) connects the Thread mesh (IEEE 802.15.4) to the home IP network (WiFi or Ethernet). It enables Thread devices to communicate with the internet and non-Thread devices. The most common TBRs in Chile are: Apple HomePod mini, Apple TV 4K (2021+), Google Nest Hub (2nd gen), Google Nest WiFi Pro, Amazon Echo (4th gen), and Eero 6/6+/Pro 6E routers. A home can have multiple Border Routers for redundancy — if one goes offline, the others maintain connectivity. For SUBTEL compliance, TBRs are multi-radio devices (802.15.4 + WiFi + BLE) and each module must be declared separately in Section B.
Thread is the preferred low-power transport for Matter, the interoperability standard from the Connectivity Standards Alliance (CSA). When a device is 'Matter over Thread', it uses the IEEE 802.15.4 radio as transport and Matter as the application layer. This combination enables sensors, locks, and bulbs from different brands to work with Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings simultaneously, all communicating over the local Thread mesh without cloud dependency. For SUBTEL, what matters is the radio (802.15.4, literal j.1), not the application protocol (Matter).
Thread and Zigbee share exactly the same physical layer (IEEE 802.15.4 at 2.4 GHz, O-QPSK, 250 kbps) but are completely different and NOT interoperable network protocols. A Zigbee sensor cannot join a Thread mesh and vice versa, even if they use the same radio chip (e.g., Silicon Labs EFR32MG24 or TI CC2652 support both protocols but not simultaneously on the same network). Key differences: Thread is IPv6-native, doesn't require a proprietary hub, self-heals, and natively supports Matter. Zigbee has a proprietary network protocol, requires a central coordinator, and needs a bridge to integrate with Matter. For SUBTEL, both are regulatorily identical: literal j.1, Track 2, 2.4 GHz.

Track 2 — Compliance QR + self-declaration
Since February 22, 2026, Thread devices no longer require prior formal certification before SUBTEL. They do require a public compliance page accessible via a QR code on the packaging, declaring bands, power, RF modules, importer with legal address in Chile, and a reference to the test report.
