How DECT 6.0 Technology Works
Understanding how DECT6.0 technology works requires a look into its underlying technical architecture. DECT6.0 is a sophisticated wireless communication standard that relies on advanced radio technology to provide high-quality transmission.
Frequency Spectrum and Radio Technology
The physical layer of DECT6.0 employs Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), combined with Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA) in a Time Division Duplex (TDD) communication manner. This complex system enables efficient use of the available radio spectrum.
Base Station and Handset Communication
In DECT6.0 systems, communication between the base station and handset is crucial. The base station manages multiple handsets, ensuring clear and uninterrupted communication. This is achieved through a highly efficient frame structure that allows for simultaneous transmission and reception.
Time Division Multiple Access (TDMA)
DECT6.0 technology utilises TDMA as a fundamental method for sharing the available radio spectrum. The DECT standard uses a frame structure consisting of 24 time slots, with 12 slots for base station transmission and 12 for handset transmission in a TDD arrangement. Each time slot lasts for 417 microseconds, and the complete frame cycle repeats every 10 milliseconds.
| Feature | Description |
|---|---|
| TDMA Frame Structure | 24 time slots |
| Transmission Slots | 12 for base station, 12 for handset |
| Time Slot Duration | 417 microseconds |
| Frame Cycle | 10 milliseconds |
This TDMA system, combined with dynamic channel selection, significantly enhances DECT6.0’s performance in environments with potential radio interference, ensuring robust and reliable communication.
Technical Specifications of DECT 6.0
The technical specifications of DECT6.0 technology are crucial for understanding its capabilities and limitations. DECT6.0 is a sophisticated wireless technology that operates on a specific frequency band and has distinct characteristics in terms of range and power consumption.
Frequency Band and Channel Allocation
DECT6.0 operates on the 1.9 GHz frequency band, which is specifically allocated for use in the United States. This frequency band is divided into multiple channels to minimize interference and ensure efficient communication. The allocation of channels is managed to prevent overlap and ensure that multiple devices can operate simultaneously without significant degradation in performance.
Range and Power Consumption
Range: DECT6.0 technology offers an impressive range, typically reaching up to 50 metres indoors and up to 300 metres outdoors under optimal conditions. The actual range can vary depending on environmental factors such as building materials and electromagnetic interference.
Power Consumption: DECT6.0 devices are designed to be energy-efficient, with features like ECO mode reducing power consumption by up to 60%. In ECO mode, the transmission power between the base station and handset is adjusted based on distance, minimizing unnecessary power usage. When a handset is in its charging cradle, many DECT6.0 systems switch to ECO Plus mode, stopping radio transmissions until a call is received, thereby reducing electromagnetic radiation by up to 80%.
Benefits of DECT 6.0 Over Other Wireless Technologies
One of the key advantages of DECT6.0 is its ability to provide superior performance compared to other wireless technologies. This is attributed to several factors that make DECT6.0 a preferred choice for users seeking reliable and high-quality wireless communication.
