DECT NR+ Frequency Band Allocations Global Guide
Advertisement
Based on the ETSI DECT-2020 NR technical specifications and global spectrum allocation data, DECT NR+ is designed to be frequency-agnostic. It can operate in any Time Division Duplex (TDD) band below 6 GHz.
However, its primary advantage lies in its use of the dedicated, license exempt 1.9 GHz DECT bands available worldwide. Unlike the crowded 2.4 GHz Wi-Fi/Bluetooth bands, these dedicated bands suffer from significantly less interference. In addition to the 1.9 GHz bands, DECT NR+ also supports standard global ISM (Industrial, Scientific, and Medical) bands.
DECT NR+ Global Frequency Band Allocations
| Region / Country | Frequency Band (MHz) | Band Designation | Notes & Usage |
|---|---|---|---|
| Europe (CEPT Countries) | 1880 – 1900 MHz | Band 1 (DECT Core) | The primary license-exempt DECT band in Europe. Regulated by ETSI, it is reserved specifically for DECT and DECT NR+ technologies. |
| United States & Canada | 1920 – 1930 MHz | UPCS Band | Unlicensed Personal Communications Services (UPCS) band. Operates under FCC regulations in North America. |
| United States & Canada | 902 – 928 MHz | Band 4 (Sub-GHz) | Supported for longer-range, sub-GHz IoT applications following FCC regulations. |
| Latin America | 1910 – 1930 MHz | Band 9 | Most of Latin America uses a slight variation of the US frequency range, operating between 1910 and 1930 MHz. |
| Japan | 1893 – 1906 MHz | J-DECT | Dedicated DECT spectrum for Japan (historically known as sJ-DECT). |
| South Korea | 1786 – 1792 MHz* | K-DECT | Dedicated DECT spectrum in South Korea. (Note: Some early ETSI draft documents list this as 1786-1892 MHz due to a typo, but the regulatory allocation is 1786–1792 MHz). |
| Australia & New Zealand | 1880 – 1900 MHz | Band 1 | Adopts the same ETSI spectrum regulations and band allocations as Europe. |
| South Africa | 1880 – 1900 MHz | Band 1 | Adopts the European ETSI spectrum regulations. |
| India & Parts of Asia | 1880 – 1900 MHz (varies) | Band 1 / Local variations | Many Asian countries follow the European 1880–1900 MHz standard, though some regional restrictions (e.g., indoor-use only) may apply depending on local telecom authorities. |
| Global (ISM 2.4 GHz) | 2400 – 2483.5 MHz | Band 3 | Supported globally as an unlicensed ISM band. Useful for global product SKUs, though subject to higher interference from Wi-Fi and Bluetooth. |
| Global (ISM 5 GHz) | 5150 – 5875 MHz | Bands 17, 18, 19 | Supported globally. Provides massive bandwidth for high-data-rate applications, though with shorter physical range than 1.9 GHz. |
| Global (Custom TDD) | 2300 – 2400 MHz & 3300 – 4200 MHz | Bands 11, 13, 14, 15, 20 | DECT NR+ supports any TDD band below 6 GHz. These bands (e.g., 2.3 GHz, 3.5 GHz) are often used for private cellular/5G networks using local or secondary spectrum licensing. |
Key Points
-
No Spectrum Licensing Fees: In regions utilizing the 1.9 GHz DECT bands (Europe, US, Japan, etc.), businesses can deploy private DECT NR+ 5G networks without having to purchase expensive spectrum licenses or pay cellular operators.
-
Polite Spectrum Access: To comply with global unlicensed band regulations, DECT NR+ features “Listen Before Talk” (LBT) and automatic dynamic channel selection. This ensures it plays nicely with other technologies sharing the same frequencies and avoids self-interference.
-
Co-existence with Legacy DECT: In the 1880–1900 MHz and 1920–1930 MHz bands, DECT NR+ is specifically engineered to coexist seamlessly with classic DECT cordless phones and DECT ULE (Ultra Low Energy) devices. The channel spacing (starting at 1.728 MHz) perfectly aligns with legacy DECT to prevent overlap.
