As the simple PAN topologies ANT first created expanded, it was found to be necessary to connect to external data structures like PCs, fitness hardware, access points, etc. to deposit the collected data for review by the user/system. Therefore, it became necessary for ANT to make that connection easy for the ANT developer. Like most ANT developments, this solution was created first for ourselves and then supported once proven and robust in ANT-FS. ANT-FS (File Share) is a comprehensive state machine that allows a battery worn collection unit the ability to be discovered, authenticate its pedigree and contents and subsequently transfer them; all while the user is uninvolved with the process. Applications in the health space require a secondary level of security for personal data, so an AES128 engine and process were added to ANT-FS. ANT-FS uses a burst channel for data transfer so most files are transferred in less time than it takes to take the device off the body, allowing quick and reliable access to the data. This speed also supports a pass-by download, for example in corporate wellness data retrieval systems at work. To help consolidate, compress and extend the data files created by these collection units, the FIT file system was created. Both ANT-FS and FIT are supported by their own downloadable SDKs.
