 Sf-5823ac product information.jpg

Sf-5823ac series high capacity remote license free point to point digital wireless bridge Based on the point-to-point proprietary wireless protocol based on dynamic TDD, the data is encapsulated into large packets for transmission, which improves the transmission efficiency (forwarding capacity: 250000 PPS), improves the bandwidth utilization (spectrum utilization: 7.5bit/hz), and increases the transmission distance, throughput and PPS forwarding capacity of the system. It can realize real-time transmission of voice, video and other data. With 2 × 2 MIMO breakthrough technology, the throughput of 35km is up to 650 Mbps, with excellent PPS packet processing ability and high anti-interference ability.

Sf-5823ac series products are suitable for carrier level point-to-point network applications, and are ideal equipment for dedicated line access or backhaul applications (including VoIP and other small packet transmission applications). By combining flexible channel bandwidth (20 MHz or 40 MHz or 80 MHz) with customized private protocols for long-distance transmission, this series of products can achieve a very high spectrum efficiency of 7.5 bit / Hz. The product has built-in dual polarized antenna (sf-5823ac) or two n-type connectors (sf-5823ac-w). The rugged and durable cast aluminum shell reaches IP-67 protection level.  

Sf-5823ac series products integrate a series of advanced software mechanisms, which can provide the best point-to-point connection performance for high-throughput long-distance link applications. The proprietary point-to-point communication mechanism uses dynamic time division duplex (TDD) technology to allocate bandwidth dynamically for the required transmission direction, so as to improve the link efficiency and significantly reduce the impact of transmission distance on link throughput. Our point-to-point products also use selective retransmission ARQ technology to enhance error correction ability and optimize data flow, so that the device can still achieve very high throughput in the case of large bandwidth, long distance and even interference.  

The new AC series products provide powerful 250kpps with a new 1.2 GHz CPU dedicated data processing chip With packet processing capability and fast wireless connection performance, the 2x Gigabit Ethernet port supports Poe relay, and when one port fails to work, the other port can continue to support single channel function, which makes the product suitable for ideal high-speed video monitoring scenarios. The port supports 802.3 standard and conforms to FCC / IC / CE / ROHS standard. At the same time, it has built-in electrostatic protection in accordance with IEC 61000-4-2 (ESD) standard and surge protection according to iec61000-4-5 (surge) standard.

Due to the high bandwidth and high stability of the product, the equipment is widely used in forest fire prevention, island monitoring, mining area, factory big data transmission and other fields.

Safe city, road monitoring, fire control, military exercises, large outdoor facilities, residential areas, etc., using wireless network transmission technology, can quickly build a wireless LAN. It is very important to establish a set of effective video monitoring management in forest area for the application of forest fire prevention system. Through the video monitoring system, the fire can be found in the first time, and it can work all day long without interruption, which can reduce the mountain patrol work of staff in Shaolin district. There are many monitoring points and wide distribution in mine, water conservancy system, coastal defense monitoring system and oil field video monitoring system. It is difficult to construct signal transmission through traditional wiring, and the workload of line maintenance in the later stage is heavy. The establishment of wireless local area network video monitoring system overcomes the limitation of geographical conditions, the wireless distribution is flexible and convenient, the link data is high, the system is stable, the power consumption is low, and the anti-interference is strong. To achieve data transmission between multiple points or between points, wireless data transmission can be realized. The establishment of a set of wireless data link can realize the net rate transmission of hundreds of megabytes between multiple points or points, and meet the requirements of various big data transmission. Wireless transmission has the advantages of strong confidentiality, flexible construction and stable system.
