Polewall was founded in 2007 and is based in Kristiansand, Norway. Funded by The Research Council of Norway, Innovation Norway, and private seed capital, Polewall has developed a low cost point-to-point optical wireless link targeting the price sensitive residential, SME, and Small Cell Backhaul markets.
Unlike other Free Space Optical links, Polewall's design uses a low power laser which is aligned using robotic stepper motors and electromagnetically adjusted lens. The LH100 is encased in a standard surveillance camera housing and can be mounted on poles, walls and other street furniture.
The LH100 provides 100Mbps symmetric transmission over 250 meters, with low latency, low jitter, low power consumption and low cost. There are no spectrum charges, but free line-of-sight is essential.
Commissioning and alignment are managed through a smartphone and/or PC application, connected using Wi-Fi to both ends of the link.
Small cell backhaul is one of the principal target markets for this technology, but it also has applications in campus environments and other short range point-to-point links.
In 2013, the European Commission awarded R&D funding of 1.15 million Euros to a consortium to develop and enhance Polewall technology further, increasing link capacity up to 2Gbps.
