Confused by conversions? Overwhelmed by Power Budget? Frazzled by the Fresnel Zone?

 

Site planning for a wireless network installation can be a daunting task.  There are multiple variables to consider and you must have a good understanding of the equipment required.

 

Lucky for you, we just simplified your life by adding a few more tools to your tool belt. L-com’s wireless calculators take the guess work out of planning a wireless network and make installation much easier. We offer five wireless calculators to help you, no matter what site planning challenges you’re facing. 

 

Power Budget Wireless Calculator

  • ·    Use this wireless calculator to determine your Power Budget
  • ·    The Power Budget is the total power being output from the wireless system in dBm

Free-Space Loss Wireless Calculator

  • ·    Free-space Loss is the loss of power over distance (assuming there is no Fresnel Effect and nothing in the way)
  • ·    This will give you a reasonable approximation of the actual loss over distance

Fresnel Zones Wireless Calculator

  • ·    Determine how high your antenna should be or how much more than Line-of-Sight (LOS)
  • ·     This calculator defines how much clearance you need and for longer links, greater than 3 Km or 2 miles, whether you may have a ground clearance problem

System Performance Wireless Calculator

  • ·    Can be used determine 3 different calculations:
    •   - Operating Margin
    •   - Maximum distance of margin operation
    •   - Required antenna power

Power Conversion Wireless Calculator

  • ·  Converts milliWatts to dBm and vice versa

Are you doing an installation, looking to understand a particular network conversion, or trying to determine what equipment to use for your wireless network?

 

Give our wireless calculators a try! L-com can help you plan your wireless network installations. These handy tools provide detailed information such as Power Budget, Free Space Loss, Fresnel Zone and more. By using these free tools you can better understand the equipment required to accomplish your wireless link.

 

Here are some examples of Wireless Calculators:


 

Power Budget Wireless Calculator

 

Use this wireless calculator to determine your Power Budget. The 'Power Budget' is the total power being output from the wireless system, or the total system gain. The FCC regulates 36 dBm as the maximum output for 2.4 GHz ISM band applications, so use this calculator to make sure you aren’t exceeding the legal limit and to determine the right antenna and radio to use for your application.

 

The total power is the sum of:

  • PLUS Radio Transmit Power 
  • MINUS cables and connectors losses 
  • PLUS antenna gain 

 

Note that in order to enter your amount of cable loss you’ll need to know what type of cable you are using.

 

 

 

 

Free Space Loss Wireless Calculator


Free Space Loss is the loss of power over distance (assuming there’s noFresnel Effect and nothing is in the way). In practice, everything interferes with the signal but this will give you a reasonable approximation of the signal loss over distance.

 

 

 

 

Fresnel Zones Wireless Calculator


This calculator defines how much clearance you need (you will require more than simple Line-of-Sight). For longer links > 3 Km (2 miles), you can determine whether you may have a ground clearance problem.

One thing to note however is that due to the nature of radio frequency propagation and the numerous factors that can affect operating range, we do not guarantee that you will achieve any specific range for your application. These wireless calculators are for estimation purposes only.
