Documents filed by Nikon with the U.S. Federal Communications Commission (FCC) about its upcoming Wireless Transmitter WT-3/WT-3A reveal that it will do more than just send photos over a Wi-Fi wireless link.
The accessory for the D200 incorporates all of the functionality of the Multi-Power Battery Pack MB-D200 (though it will accept only one EN-EL3e battery rather than two), has a 10/100 Ethernet port for the transmission of photos over a wired network connection (in addition to 802.11b/g wireless networks), it allows the D200 to be controlled via a wireless or wired link and it will also make it possible to print direct from the camera to a networked printer or wirelessly to a PictBridge printer (the latter requires a Nikon PD-10 Wireless Print Adapter be connected to the printer).
In addition, the radio inside the WT-3/WT-3A appears to be more powerful than that of the current Wireless Transmitter WT-2/WT-2A, which may translate into greater range. The single EN-EL3e battery will power both the camera and the transmitter for a Nikon-specified 1600 JPEG Basic frames with the transmitter off, 1100 frames when the Ethernet port is used and 1000 frames when the wireless link is active.
The submission date on the various documents put forth by Nikon is August 4, 2006. Among the documents, which are in PDF format, is the user's manual in four parts, plus photos of both the Wireless Transmitter WT-3/WT-3A and its internal circuitry.
Nikon USA Senior Technical Manager Steve Heiner indicates that a precise ship date for the WT-3/WT-3A as not been set, though earlier this summer Nikon announced it would hit the streets in the fall of 2006.
Previous FCC filings for the Nikon Wireless Transmitter WT-2/WT-2A and Canon Wireless File Transmitter WFT-E1 are also on the FCC site.
Thanks to Doug Urner for bringing the WT-3/WT-3A information to our attention, and to Thomas Sapiano's new DPWiki site for bringing it to Urner's attention.
