Of the multiple outdoor wireless solutions, Micronet SP915NLOS-7 and SP915NLOS-9
wireless products can apply for the deployment in Non-Line-Of-Sight (NLOS) arena, where
the landscape of the areas could be with hilly terrain, or the areas may be much like
suburban communities that are surrounding with many of trees or foliages nearby, or the
areas are very close to the forest or in the mountain areas or maybe just in the center of
forest, as the purpose for a fire-alarm observatory. In some wireless communication area,
there could be some obstructions, buildings or blocks which may obscure Line-Of-Sight
(LOS) between the wireless access points and the backhaul infrastructure (e.g., of Wireless
Internet Service Provider or so-called WISP). The SP915NLOS-7 and SP915NLOS-9
operate on frequency band 700MHz and 900MHz, respectively.
Most of people may have one question - In contrast, Non-Line-Of-Sight (NLOS)
What are the major differences between wireless environment can avoid most of
the normal outdoor products and NLOS obstacles such as trees, building, hills,
outdoor products? To explain of this, most mountains, walls or any other blocked

works under the environment of Visual- the receiving antenna. The signals arriving
Line-Of-Sight (VLOS) or Radio-Line-Of- at the receiver may consist of components
