DLB Propeller 2
Outdoor Wireless Access Point/Bridge with Directional Antenna

Product Features

DLB Propeller 2 is an outdoor wireless device that supports 2.4GHz band and can also be used as an access point or bridge. It supports a wide operating temperature of -40 to + 65 °C and can be installed in places with severe temperature conditions.

Despite its lightweight and compact design, it is possible to build wireless APs and wireless bridges with a line-of-sight of several hundred meters.

Achieve low-cost and easy wireless LAN construction.

This product is RoHS compliant. 

Many of our customers are happy to have chosen DLB Propeller 2 as solution.

– IP camera installation cost is reduced by about 70% compared to the configuration using a wired cable
– Many satisfied customers were happy that cameras could be installed easily without the need for cable wiring.
– Introduced by local governments, power plants, steelworks, and automobile factories
– Introduced by a famous camera manufacturer.
– Cumulative shipments of the series exceeded 5,000 units

The perfect solution for these customers

– Want to use it for bridging several hundred meters between the right and left banks of rivers, between railroads/roads, between factory buildings, etc.
→Wide operating temperature from -40 to + 65℃
→Supports PoE (original method) and can be used in places where it is difficult to wire the power supply to the terminal.
– In a freezer warehouse
→Wide operating temperature from -40 to + 65℃
– Use for both outdoor wireless LAN-AP and bridge applications
→Can be used with either AP / bridge depending on the installation orientation
→Maximum number of clients: 127
– Want to introduce it easily
→No license required and low cost

(Ipoll function that enables highly efficient multipoint connection)
In the multipoint connection configuration by Propeller, highly efficient data transmission can be achieved without reducing the throughput by using the unique ipoll functions.

(Wireless LAN bridge construction)
Network construction can be easily realized even between bases separated by several hundred meters or more.
