COMPARATIVE ANALYSIS

It is useful but difficult to compare the research being done in different countries in the area of wireless communications. First, the panel visited only a handful of companies in each region. Second, these were generally the larger companies with more visibility. Third, proprietary research was not included as part of any discussion. Nevertheless, based on what the members of the panel saw, the WTEC panel has attempted to compare the research activities in various regions, as summarized in Table 2.1 below.
