The Alvarion Point-to-Point (PtP) Calculator helps simplify the bid process to make it even

easier to resell Alvarions robust and easy-to-deploy solution for PtP links. Quickly and easilycalculate the necessary components and specifications to create detailed quotes on completewireless broadband access deployments for your customers.

You will need to collect some information from your customer or prospective customer beforeusing the PTP Calculator. This information includes:

Global Positioning coordinates for Site A and Site B (the two sites they wish to connect). Height of the buildings or towers where the antennae will be located. Their preferred frequency or frequencies. The expected bandwidth usage. Whether they wish to use integrated, external or would like to consider both

antenna options.

Follow these steps to calculate a PTP link in less than two minutes:

Step 1: 10 SecondsStart here: https://airpartner.alvarion.com/index.php?content=ptp_estimator

Visit the online PTP Calculator that is part of the AIRpartner Web site and agree to the Disclaimer.

Step 2:30 secondsEnter the latitude and longitude for Site A, and Site B. You may rename the two sites forconvenience, clarity and professionalism, and to enable easy reference to the quote when needed.If the coordinates are provided in a different format, choose the appropriate one. Sites may beconnected anywhere within the US, Canada or the Caribbean.

NOTE: You can select DEFAULTS at any time to return all fields to their original values.

Step 3:40 SecondsEnter the height of the tower/building where the antennas will be located at each site. You maytype in the measurement value, either Imperial or metric, or slide the antenna icons up and downto match the specifications.

DisclaimerThe results provided by this tool are theoretical only and are not guarantee for link availability or

performance. The data is provided in order to assist initial link estimation and does not take intoconsideration the ambient noise floor. The throughput provided by this tool is the maximum achievableper rate and assumes ideal conditions. Interference, distance, obstructions and other factors can all

reduce the actual achievable throughput. The user is responsible to select the appropriate radio regulatorydomain and conform to all rules and regulations of the particular country.

Select Estimate to continue.

Step 4:55 SecondsThe PTP Calculator estimates the link range based on antennas heights and terrain.

The example below shows a graphic with the following information, automatically performing ananalysis on the link:

1. Link graphic

a. The black line of the link graphic shows the line-of-sight.

b. The green area of the link graphic shows the 60% Fresnel Zone of the optionalfrequencies (5.3, 5.4, 5.8 or 4.9 GHz) in the territory.

c. A red area would appear if a link could not be established and highlighted under theLimitations tab.

2. Site A and Site B are shown at each end of the link with suggested azimuth (Trueand Magnetic) direction for each antenna.

3. The height of each antenna is also shown. EXAMPLE - Site A:

a. Elevation 101 ft (Altitude + Antenna Height)

b. Altitude (Based on Terrain) 3 ft

c. Antenna Height 98 ft

4. Optional available frequencies are also shown for the specific location, taking

into account the different regulations and allowed power outputs.

a. Select the preferred frequency if specified by the customer.

b. If the frequency is not specified, use the expected modulation rate, capacity,bandwidth usage and the usage of integrated or external antennas to determinewhat frequency would be best suited.

5. Select the Limitations tab (previously mentioned in 1c) to view any knownlimitations for the specific coordinates of the link.

Step 5:60 SecondsChoose the desired link by clicking Select to receive full technical information about theproduct, antennas and budget.

Step 6:75 SecondsSelect Map View to see your link on a map, using Google Earth. A button to download andinstall the Google Earth software is also provided for your convenience.

Either save the file for later or open it to view your location. The file will be included along with

the final quote email for your customer to view. Once the .kmz file is opened, double-click on thesites to see the signals path through the landscape and the relative heights of the towers.

Step 7:115 Seconds

Create the quote by selecting Generate Quote. Enter your company information under From,including a billing Reference Number. You may also personalize the Subject Line. Enter thecustomer information under To. Use the Comments box to add notes.

Select Send. The customer and you will receive a copy of the quote by email, including all theinformation about the link and a .kmz map file that will open using Google Earth.

The customer can print and sign the quote, and fax it back to you as an order.

NOTE: When you enter a fax number under From, it will be referenced at the bottom of thequote so the customer can fax the signed quote and complete their order.

It is just that easy to quickly calculate a point-to-point link and create a professional quote.

Additional features:

1. If you have unique requirements for the landscape, climate or antenna preference youmay change these parameters. The PTP Calculator will recalculate the performance for thespecified area.

2. The standard fade margin is automatically calculated. You may enter a new value to adjustthe fade margin in order to compensate for an extra noisy environment, rain, foliage orother conditions by selecting the manual mode.

3. There is also space to add additional components or products with their quantities andprice.
