Proxim TSUNAMI CPN 65756B 用户手册

When you read about wireless outdoor products, you often encounter the terms output power of the radio 

and gain of the antenna equipment as measures for the strength of the transmitted signal. 

▪ 

Output power of radio equipment often depends on maximum limits as defined by local radio regulations; 

consequently, output power is, by definition, not the way to enhance wireless performance. 

▪ 

High gain antennas are larger in size than low gain antennas and are characterized by a narrow focus of 

the antenna beam.  These two characteristics make it more difficult to aim the antennas and adjust 

antenna alignment to optimize the performance of the wireless point-to-point link. 

The Tsunami outdoor solution is based upon the following principles: 

▪ 

An output power and antenna gain that comply with the maximum limits as defined by local governing 

bodies concerning radio transmissions. 

▪ 

Enhanced radio sensitivity for optimal receive quality of radio signals transmitted by remote antennas. 

The range of your outdoor antenna installation is closely related to a number of different factors. To let you 

determine the range of the Tsunami MP.11a antenna system in your situation, we have defined the following 

formula: 

where: 

Maximum Range 

Identifies the theoretical maximum that could be achieved under optimal 
circumstances using the available Tsunami MP.11a products according to their 
specifications and in compliance with local radio regulations. 

Cable Factor 

Identifies a correction value (percentage) that compensates for additional cable 
losses related to the type of cables used at both ends of the wireless link.  (See 
“Cable Factor” on page 17.) 

Clearance Factor 

Identifies a correction value (in percentage) that should be used in case the 
signal path of your wireless link does not provide the minimum clearance as 
listed in the Maximum Range table. (See “Clearance Factor” on page 18.)
