The ﬂow of network installation routines Among the I&M routines used for RF wireless networks, four are especially important: • Conﬁguring the hardware elements and software algorithms in a base station • Testing the network interconnections of the hardware parts and their respective optimizations • Conducting initial drive tests whereby a vehicle travels into the ﬁeld to check the quality of received base station signals prior to authorization of network operation • Final optimization, troubleshooting and documentation for acceptance tests RF wireless networks are not the only emerging application requiring I&M procedures and each market segment (e.g., aerospace/defense, mobile and general purpose) is driven by its own unique set of needs (Figure 3). Therefore, all I&M procedures demand high levels of precision, reliability and timely execution to accommodate the emerging range of ﬁeld applications. Identifying suitable I&M solutions According to a recent study, the current worldwide market for 3- to 4-GHz handheld signal analyzers is estimated to be around US$100 million. As a handheld solution, these simple, general-purpose tools are well suited to address the needs of the large population of users in wireless I&M applications and, in particular, RF networks. A prime example is the LAN-remote controlled spectrum analyzer, which offers a fast and efﬁcient way to monitor key network parameters over long period. The data obtained from this instrument can later be recalled and analyzed using computer-assisted algorithms to provide an immediate and intuitive overview of the situation during installation of a network’s hardware components. Because such instruments can be used to ensure broadcasting service quality in the ﬁeld — during long periods of time and in critical situations — they are uniquely qualiﬁed to address the critical I&M routines previously detailed. 43 Agilent Measurement Journal
