A new device from Motorola has passed through the FCC, and it is surrounded with questions. The device isn't described as a smartphone, but rather as a "touch computer", although everything else seems to point to it being a mobile device of some sort. The only answer we have looks like an announcement from Motorola planned for September 17th.
The FCC filing is for the Motorola TC55AH. It is a phone-sized device at 138mm by 77mm (5.4-inches by 3-inches), which would put it a bit bigger than the Moto X. More specifically, it puts the device at about the same height as the LG G2 and the same width as the Samsung Galaxy Note 3. The device also includes an LTE radio as well as the WiFi, Bluetooth, and NFC connections you would expect in a smartphone; and, it runs Android 4.1.2.
The strange thing is that if you Google "Motorola TC55", the first result is a forum post of someone working with a developer-only smartphone under that name. And, there is mention on the Motorola Enterprise website which mentions the TC55 is planned for launch on September 17th. The only description is that the device is "built for business with a personal touch".
None of this helps us figure out what the device could be. There have been theories floated that it could be a point-of-sale device, but we just don't know. Of course, we should find out next week.
