modem . The ability to turn on and off the various circuits in the 
host/terminal allows for the identification and analysis of the 
host/terminal components that are responsible for desense. This 
approach to desense troubleshooting can greatly speed up the OEM 
integration effort. 
For more detailed information about desense, refer to “Guide to 
Desense” on page 132. 
Regulatory Compliance 
Most countries where the final product will be sold generally require 
approval from the local government regulatory body. In the US, the 
FCC requires that two individual requirements be met before the final 
product can be certified. The first test, the FCC Part 15 qualification, 
requires you to prove that the product electronics hardware does not 
yield local radiation capable of affecting other equipment, such as TVs, 
computer monitors, and so on. 
The second test (FCC Part 90) requires you to prove when the modem 
transmits, it remains properly in its allocated channel spacing, and does 
not produce spikes or splatter in other frequencies. Wavenet undergoes 
FCC testing with the modem stand-alone to ensure compatibility with 
these requirements. But since the eventual transmit capability of the 
modem is highly integrated with the power supply and antenna system 
of the host/terminal, the fully integrated product must be submitted for 
final regulatory approval. 
In addition, regulatory bodies can require the wireless modem to 
transmit random data patterns on specific frequencies while 
incorporated in the host/terminal. The Boomer-II OEM modem 
incorporates special debug modes to allow this kind of testing, 
provided the host/terminal application can issue the required 
commands to the modem. 
The entire regulatory process can take many months to complete and 
should start early in the development cycle. The exact regulatory 
requirements of each country change from time to time. For efficient 
regulatory processing, it is recommend to use the services of 
specialized regulatory consultants to determine the specific 
requirements at the time of manufacture. 
To prepare for regulatory testing, you need to integrate the pass-
through mode into the product design (see “Enabler Functions” on page 
73). Wavenet provides the ability to key and dekey the radio at the 
required frequencies and modulation levels from an external PC via the 
pass-through mode. 
For further information about regulatory compliance, refer to 
“Regulatory Requirements” on page 21.
