Introduction
The Nikon WT-3/3A is an upcoming transmitter built for the Nikon D200 DSLR. Like its predecessor, the WT-3 uses IEEE 802.11g to automatically upload images to an FTP server as soon as images are shot. In addition to FTP support, it also provides support for the PTP/IP protocol to allow remote control capabilities. Unlike its predecessor, however, the WT-3 also has an Ethernet port for high-speed wired transmission of images.
When coupled with an FTP server such as Pixagent's ITP, the WT-3/3A will move images to a computer so that they can be processed/displayed in parallel with their shooting. This allows the photographer and their clients immediate access to their photographs in order to maximize the speed of their workflow.
PTP/IP Support
When used in this mode, the camera will behave as if it were teathered to the computer via a USB cable. As such, users can remotely control the camera (fire the shutter, change settings, etc.) over a wireless (or wired) network. It will also automatically retrieve images from the camera, although the user does lose some granularity over the way they are sent.
RF Characteristics
Using information filed with the FCC durring the licensure process, the following tables provide basic information about the RF characteristics of the Nikon WT-3A. Note that these tests were performed on the North American WT-3A variant and may be different than the WT-3 sold in other areas of the world.

Design
The WT-3/3A acts as an optional vertical grip for the Nikon D200. It provides the same basic functionality that the existing MB-D200 offers, except that it provides only one battery slot. It communicates with the camera using a USB 2.0 cable teathering it to the data port on the camera, and draws power from the onboard battery (which also feeds the camera). Three LEDs on the rear-left of the unit provide basic information about it's opperation, but most of the controls are performed via menus within the camera.
Compatibility
The WT-3/3A is supported by the Nikon D200 at this time and may support future compact DSLRs. Unlike the WT-1 and WT-2, the WT-3/3A will not function with the D2-series cameras.
Variants
The WT-3/3A is sold as two basic variants, the Nikon WT-3 and the WT-3A. The later is only sold in North American markets and only has access to channels 1 through 11 of the 2.4GHz WiFi band to comply with local regulations. The former variant is sold in other markets and covers all 13 available channels in the 2.4GHz WiFi band. Other than that, the two transmitters are identical in both functionality and form.
