Combining Japan’s MIC 2025 Notice No. 12, ARIB STD-T109 v2.0 new rules, and TELEC’s official testing guidelines, this article breaks down the "general + specialized" logic of standard items, highlighting product-specific testing blind spots and 2026 new requirements to help you avoid "rework due to missed tests."

I. Core Logic of TELEC Certification:

TELEC certification standards are designed to "prevent wireless devices from interfering with Japan’s critical frequency bands (e.g., aviation, weather radar)"—based on three core dimensions:

1.RF Function Complexity: Simple transmitters (e.g., remote controls) require only basic RF testing; complex modulation (e.g., multi-band Wi-Fi) needs additional anti-interference algorithm testing.

2.Frequency Band Sensitivity: 2.4GHz is an open band (testing focuses on power limits); 5GHz/6GHz involve radar avoidance (enhanced DFS required); 920MHz is Japan’s exclusive IoT band (unique power requirements).

3.Usage Scenario Risk: Automotive devices require temperature shock testing (-30℃~85℃); medical peripheral devices must avoid the WMTS band (608~614MHz); portable devices (e.g., smartphones) need SAR testing (≤1.6W/kg).

This explains why:

·A children’s smart watch (Bluetooth) requires SAR testing, but a Bluetooth speaker does not.

·A home Wi-Fi router undergoes basic DFS testing, but automotive Wi-Fi needs additional vibration testing.— Scenario determines the "package" of standard items.

  II. 2026 TELEC Certification Standard Items:

TELEC standards are divided into "general mandatory items" (all wireless devices) and "specialized items" (added based on RF technology/scenario). 2026’s core changes focus on 6GHz bands, UWB technology, and automotive scenarios.

1. General Mandatory Items (Baseline for All Wireless Devices)

These are non-negotiable requirements—2026 testing accuracy has increased by 10%:

RF Parameter Testing (per MIC Notice Annex 43/44/45)

·Tests include "transmission frequency tolerance" (≤±20ppm), "EIRP (Equivalent Isotropically Radiated Power)" (band-specific limits: e.g., 2.4GHz ≤100mW, 6GHz ≤250mW), and "spurious emissions" (-26dBm/MHz @1m, avoiding interference with broadcast/TV bands).

·2026 New Addition: "Band Edge Suppression" testing—6GHz devices must achieve ≥40dB power attenuation at band boundaries (e.g., 5925MHz, 7125MHz) to prevent out-of-band interference.

EMC Testing (per J55022/CISPR 32)

·Tests conducted emissions (150kHz~30MHz) and radiated emissions (30MHz~6GHz). Class B devices (household) have 5~10dB stricter radiated limits than Class A (industrial).

·2025 Update: Wireless charging-enabled devices (e.g., wireless charging headphones) require additional "EM radiation during charging" testing to avoid interfering with nearby devices.

Electrical Safety Testing (per JIS C 62368-1)

·For power adapter-equipped devices: Insulation withstand voltage (AC 1500V/1 minute), temperature rise (housing ≤60℃), and mechanical strength (1.2m drop test).

·2026 New Addition: Wearable devices require "battery overcharge protection" testing—automatic power cutoff when charging current exceeds 150% of rated value.

2. Specialized Testing Items:

These differentiate testing requirements by product—2026 updates to multiple specialized standards directly impact compliance:

(1)Wi-Fi Devices (2.4GHz/5GHz/6GHz) – 2026 DFS Enhancement

·5GHz Wi-Fi (e.g., Wi-Fi 6):Band-specific testing:

·6GHz Wi-Fi (Wi-Fi 6E/7) – 2026 New Addition:Mandatory "Enhanced DFS (DFS+)" testing—must recognize Japanese military radar signals (e.g., 13GHz band) and switch channels within ≤30 seconds.Optional (but carrier-required for network access): "Automatic Frequency Coordination (AFC) simulation" testing.Common products: High-end routers, VR devices, automotive Wi-Fi 6E modules.

Standards: JIS D 0203 (environmental adaptability), MIC Notice Annex 50 (frequency bands)

-Basic Testing:All automotive wireless devices (e.g., in-car Wi-Fi, Bluetooth speakers) require "temperature shock" testing (-30℃~85℃, 10 cycles) and "vibration" testing (10~2000Hz frequency, 20m/s² acceleration).
