Remarkable wireless transmission range and coverage, the best choice for enterprise voice communication solutions
Unlimited cordless communication ability has always been the goal pursued by enterprises. Compared to most popular cordless phone products with a communication range of about 350 meters on the market, the technology of Frequency-Hopping, High-Power and High-Sensitivity have successfully created up to 5 kilometers, 250,000 sq. ft. and 3,000 acres range performance. The communication range can fully meet the demands of enterprises and enhance their competitiveness.
Multiple Base Design
In addition to remarkable communication range, the multiple base design of Senao long-range cordless phone systems also have the advantages of high mobility in mobile communications (Cellular-like architecture, roaming & handover), allowing the internal communication of the enterprise to go from point-to-point and then to point-to-area applications are ubiquitous.

Excellent Ability of Anti-interference
The wireless transmission frequency band adopts 902~928 MHz, and 128 channels are divided into 200 KHz bandwidth. Through frequency hopping spread spectrum technology (Frequency Hopping), 1 frequency band is hopped every 10 ms (0.01 second), so that the transmitter can be on these channels Jump between. When the communication system starts to operate, the slave and the host will simultaneously occupy one channel (fx) for communication, after 10ms (0.01 seconds), they will jump to another channel (fz), and then jump to the channel (fy) every 10ms. It will sync to the next channel every 10ms until the end of the call. The advantage of this frequency hopping is that regardless of whether the channel is interfered or not, the system will always hop to other channels to maintain the overall signal clarity during the call, and the receiving end also receives the signal in the same hopping sequence to achieve the purpose of communication, and Reduce other noise interference and ensure communication quality.

Legacy and IP Networks Integration
Senao's new generation of voice solutions adopts A/D conversion design (Analog-to-Digital Converter), which converts analog voice signals to digital packets, which are integrated and processed by MCU/DSP, and then through D/A conversion design (Digital-to-Digital Converter), which reverts digital packets to analog voice signals, perfectly integrates the communication architecture of analog voice circuit switching and digital Internet packet switching on the same platform, providing enterprise users with diversified needs for voice communication platforms. Enterprise users can freely choose to use traditional network or IP network for voice communication according to actual business needs and are no longer limited by the trouble of having to choose between traditional analog and digital communication.

Rugged Industrial Design
Industrial design that is comparable to military regulations, sturdy and durable, can withstand 54 meters of drop test at a height of 2 meters, and strengthen the service life of the product, no matter how harsh the corporate environment, always ensure Unblocked internal and external voice communication.
