         Experimental License for GPS Radiator for System Testing and Lab Use



On-Ramp Wireless designs and manufactures the Ultra-Link Processing™ (ULP) wide area
wireless networking system. ULP operates in the unlicensed 2.4 GHz ISM band and enables
wireless sensor communications for Smart Grid, Energy Efficiency, Industrial Condition Based
maintenance, and security and location tracking applications. Deployments of a ULP network
can be inside a factory or building enabling tracking of critical sensors for predictive
maintenance or in a metro or regional type network for wide area coverage.

In the wide area deployments the ULP Access Points use GPS timing (1 PPS signal) to
maintain a common time reference between the Access Points on the network.

The experimental license is requested for a GPS signal repeater to be used only in On-Ramp
Wireless’s system test lab. This will provide On-Ramp’s engineers the GPS L1 timing signal for
use in design and testing of our products.

The following are additional details used in the submittal:

   1) On-Ramp Lab




                                                                            GPS
                                                                            Repeater in
                                                                            corner of lab



       The On-Ramp lab is 40 feet by 40 feet. The diagonal for the lab is 57 feet. For the NTIA
       regulations the calculation of 57 ft + 100 ft = 157 ft was used to ensure the signal was
       less than the required power 100 feet from the building.


2) The cable run from the lab to the top of the building is 150 feet. The cable is LMR400
   and the associated cable loss is 9.3 dB




3) The cable loss and distance from the GPS radiator was included in the spreadsheet
   below to ensure that the Repeated Signal Power was <-140 dBm 100 feet from building.
