The LANDMARKA range now covers the 867MHz band as well as the 433MHz and 458MHz low power telemetry bands. Customer requests fuelled the need to accommodate these alternative frequencies due to the increasing use of temporary traffic lights.

Unfortunately poor design of traffic lights radio systems has resulted in increasing interference in the 458MHz band, often in a 3km radius. This is due to the constant carrier signal that is used - a technique much maligned throughout the earlier days of low power radio development. This current application would seem to be a step backwards.

However, for those users who find this a problem the alternative frequencies are directly compatible in every way - same functionality, same case sizing, same power supplies - so they are a true alternative implementation.
