Continued Growth of Connected Vehicle and M2M Highlighted at MWC

March 13, 2012By

The Mobile World Congress in Barcelona is getting bigger every year — so much that it’s almost a mini CES that is hard to navigate and find companies, much less big location-based services news. While there were no big jaw-dropping mergers and acquisitions, big product roll-outs and partnerships, this conference will continue to be the main showcase for location companies wishing to establish a presence in Europe. read more

Letters to the Editor: Antennas and the Human Body

March 1, 2012By

We have been reading with much interest the Innovation column, “GNSS Antennas and Humans” (Innovation, February issue). As the interaction with the human body is something many companies designing GPS into their products do not consider, it is great to see this topic being given some recent attention. We do feel, however, that we should comment on some issues we see in the article, especially as one of our antennas has been used as part of the testing. read more

Expert Advice: Thank Your Lucky Stars

March 1, 2012By

The industry’s destiny is somewhat controlled by a federal agency that is not very knowledgeable about how, when, and where GPS is used — although I’m sure they’ve learned a lot in the last 14 months. read more
