Product description
Sf-5823wj series high-capacity long-distance license free band point-to-point digital wireless bridge, based on dynamic TDD point-to-point proprietary wireless protocol, the data is sealed into large packets for transmission, which improves the transmission efficiency (forwarding capacity: 35000 The bandwidth utilization (spectrum utilization: 7.5bit/hz) is improved, and the transmission distance, throughput and PPS forwarding ability of the system are increased. The 64 byte transmission delay of the system is less than 2ms, which can realize the real-time transmission of voice, video and other data. It has high throughput of 220 Mbps and high throughput of PPS.
Sf-5823wj series products are suitable for carrier level point-to-point network applications. They are ideal equipment for dedicated line access or backhaul applications (including VoIP and other small packet transmission applications). By combining flexible channel bandwidth (20 or 40MHz) with customized private protocols for long-distance transmission, this series of products can achieve a very high spectrum utilization of 7.5 bit / Hz. The product has built-in dual polarized antenna (sf-5823wj) or two n-type connectors (sf-5823wj). The rugged and durable cast aluminum shell reaches IP-67 protection level.
Sf-5823wj / sf-5823wj-w 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 built-in RF module of the new WJ series can transmit power up to 28 DBM (+ / - 2 DBM), and can still reach 23 DBM (+ / - 2 DBM) in the highest modulation mode (MCS 15), so that a stable long-distance link can be established with the built-in antenna. The product is equipped with Gigabit Ethernet port and supports 802.3af standard, which is more flexible and convenient to use. 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.
