ST5801GB series offer three main features:

  • Multi-Hops feature with low loss of backbone throughput

The throughput reduces about 5~8Mbps/each Hop. From the 5th Hop on, the Throughput will not reduce anymore. The throughput can be remained more than 120Mbps. Even after 10 Hops, the latency is still within 10ms.
ST5801GB has 3 RF modules, so it can support 3 backbones for the gathering of wider bandwidth from different directions.

  • Multi-Hops + Mesh Networking System

This solution is for carrier-grade project that needs to provide wireless internet service or large-scale wireless surveillance image transmission.

To solve the problem that the normal internet system breakdown, Mesh Network features such as auto route selection and self-healing is adopted here.

  •  Multi-Hops + Mesh Networking System + High-Mobility

This is for carrier-grade project that provide high-mobility transmission service in a large area. EX: wireless high-mobility surveillance transmission in city roads or highway, railway high-mobility data transmission, rapid transit (subway) high-mobility data transmission, and even high-speed train high-mobility data transmission.

Mesh Networking System, collocating with the wide-bandwidth of Multi-Hops and the specially designed Mesh Client, high-mobility data can be transmitted fast and automatically via Mesh Networking System.

ST5801GB series have the advantages as below:

  • Flexible wireless backbone deployment options

Multiple radio interfaces were integrated by IO-Power’s core data switching technology inside the ST5801GB-M series. Each radio interface can be configured independently to meet different wireless connectivity purposes. With the fast data switching between multiple radio interfaces, the backbone throughput will remain in a high level even after several relays between APs.

  • High-performance wireless backbone

With the new generation 802.11N MIMO technology, the ST5801GB-M, offer data link rate up to 300Mbps in each single radio interface, 160Mbps bandwidth. Short Guard Interval and Frames Aggregation methodology configurations improve the efficient of backbone usage, with total data link rate 300Mbps and 320Mbps bandwidth.

  • Security and efficient client connectivity

The nimble QoS (Quality of Service) configuration provides flexible management of user’s access bandwidth of wireless connectivity. Perfect integrated with central RADIUS server and data encryption technique, the ST5801GB-M series provide a secure wireless connectivity for each client device.

  • Mesh Networking Function (Selectable software)

When installing backbones in a large-scale area, Mesh Networking function can be selected to offer special features as below:

A. Mesh data transmission with OSI (Open System Interconnection Reference Model) Layer 2, Data Link Layer, can fasten the data handover and self-healing for connection, and lower the bandwidth loss because of Hopping. It can offer 100Mbps bandwidth after 10 Hops.

B. Automatically searching for the best route

C. Automatically disconnecting and searching available connections

D. Automatically balancing data rate

E. Automatically refreshing the node information of Mesh Networking System

F. Automatically scanning and choosing channels

G. Automatically update the system via Server or Gateway

H. Automatically forming internet cloud

I. Support fast transmission via automatic route searching

J. Support fast roaming calculation of signals and data rate

K. Support wide-bandwidth Mesh Networking transmission

L. Support Multi-Gateway for backup use
