* RTC = Real Time Clock. The product knows the time and is able to send positions on specific time/day instructions as opposed to sending by predetermined cycles. While Cobblestone is able to send on a predetermined cycle, e.g., 'once every ~24 hours, approximate time', Gemstone is able to send on a given specific time, e.g., 'Tuesdays at 5:43 AM and Fridays at 3:40 PM'.
**OTA = Over The Air, wireless. This allows for future firmware and feature upgrades of the products even if the product is in the field."
