Table 1 Advantages and disadvantages of the first- and second-generation real-time stations

From: Real-time nodes permit adaptive management of endangered species of fishes

Environet Biotelemetry Autonomous and Real-Time Database (BARD)
Detection times stamped by node GPS (m/d/y hh:mm) Detection times stamped by receivers (m/d/y hh:mm:ss:ms)
If offline, all detections are stamped with time of next successful polling If offline, all detections get original time stamp from receiver at time of detection
Polling limited to minute polling rate due to cellular node time stamping Greater temporal resolution, since time is independent of cellular node
Netronix server space limited SQL space permits 4 tBytes; “unlimited” space with Amazon cloud
Limited to 20 detections per minute Unlimited detections per polling interval; 196 kByte limit, which equals about 2000 detections per polling
Web interface not adaptable Web interface with SQL database is adaptable to visualize any query
Displays single monitor location Displays multiple locations for comparison
Unable to input a list of unique IDs Can provide list of specific IDs
  Current database, 101 gBytes with 52.7 million detections
