Link Operation

 

In terms of performance, the FlexNET products are based on an OFDM radio that supports up to 64QAM adaptive modulation and 52 data subcarriers. FlexNET link products function on license-exempt frequency bands. Utilisation of license free frequencies enables quick and flexible deployments of wireless broadband networks. Link or backhaul connections are typically implemented using Line-Of-Sight (LOS) conditions, but NLOS is also acceptable in certain cases.

 

The FlexNET link products operate on unlicensed frequency bands, 5.470- 5.725 and 5.725-5.850 GHz frequencies, using OFDM radios based on adaptive modulation scheme. The link products work based on dynamic fall back rates. This supports maximal data rate and throughput even in varying conditions where some interference may exist.

 

FlexNET products are fully outdoor proof and can be installed directly to the desired location. The units support temperature range of -40 to +55ºC and are IP65 rated to ensure efficient operation even in harsh environments. The product is powered up by an external power supply unit, which can also be installed outdoors. The link units can be connected to the existing network infrastructure by Ethernet cabling.

 

The key strength of the FlexNET pointto- point link product (ASN-700) is that the radio and antenna components are integrated into the same hardware. This kind of design has superior sensitivity that leads to better range and capacity features in network deployments combined with easy installation. The link antenna is a narrow beam panel antenna that has high gain (20 dBi), making it an ideal solution for point-to-point connections. The link antenna has also extremely low side lobe level that supports accurate and scalable network topologies with link deployments.

 

The FlexNET link repeater (ASN-800) has two radios for more versatile link connections, supporting both point-topoint and repeater type deployments. These two radios can be used on 5 GHz frequencies with external antennas. The radio units can be configured independently. The key feature of the FlexNET link repeater is the support for scalability needs in wireless networks, where range and capacity improvements are needed. This product offers 2 x 54 Mbps capacity that can be configured for different types of repeater deployments. The FlexNET link repeater has also 2 Ethernet connections for network and capacity expansions. Main application for FlexNET link repeater is to enable building and deployment of extended link connections which allow combination of two point-to-point connections for longer range distances.

 

The FlexNET link repeater can also be used in areas where non-line-of-sight obstacle can be avoided by building a link connection which avoids the obstacle and round the link connection in more free space environment.

 

The FlexNET link products are configured via an easy-to-use web based user interface.
