evaluation board allows for maximum flexibility in accessing and 
controlling connections into and out of the modem. Wavenet also 
provides various software utilities that can help in performing 
development tests. See “Testing” on page 73.  
Supplementing the test environment, the network operator sometimes 
provides a live development network, one separate from the production 
network on which you can develop and test your application. 
Develop Supporting Applications Software 
To develop supporting applications software, perform the following 
steps: 
 
Select a communications model 
 
Develop end-to-end applications software 
Select a Communications Model 
Select a communications model. Most vertical market applications use 
fleet (SCR) connections to a single Enterprise Server Application, 
whereas horizontal applications typically use a gateway to allow 
connection to the Internet or other external networks. See “Air 
Interface Protocols” on page 25. 
Develop End-to-End Applications Software 
In addition to coding the product-specific features for your application, 
you are urged to incorporate RF-specific reporting and monitoring 
features, such as received signal strength (RSSI), channel quality, and 
in-range/out-of-range conditions. Many applications track the number 
of packets sent and received and the various events and status 
indicators available from the modem. The Boomer II modem uses a 
packetised serial interface (Native Control Language 1.2) to allow the 
application to simultaneously monitor RF-related information and 
application-specific data.  
Test and Approve the Product 
To test and approve the product, perform the following steps: 
 
Perform EMI and desense testing 
 
Set up a final test environment 
 
Install and field test the product 
Perform EMI and Desense Testing 
Proper modem operation requires that you minimize EMI 
(electromagnetic interference) radiated from your product’s platform. 
Excess noise significantly reduces the wireless modem’s ability to 
receive, making the network less likely to be heard.
