I can see that some Mobile nodes have the name with Baseline, some nodes have SMS in their name, for example, 1. US New York Baseline 4G 2. US New York t-Mobile 4G 3. US New York t-Mobile 4G - SMS What is the difference between them?
The mobile location with the name "Baseline" means that it is using broad band connection, not wireless connection. Other locations with service provider name means that it is using wireless connection provided by the specific wireless service provider. The location with the name "SMS" means that it can be used to test SMS function.
