Wireless Transmitter WT-4 The WT-4 is a high-performance wireless transmitter that offers diversified image transfer capabilities when connected with the Nikon D3 or D300 via USB cable. It supports wireless LAN conforming to IEEE 802.11b/g, IEEE 802.11a, and wired LAN conforming to IEEE 802.3u (100BASE-TX) and IEEE 802.3 (10BASE-T). Transmission range when wireless LAN is used is approx. 180 m (IEEE 802.11b/g) or 260 m (IEEE 802.11a). (Varies according to transmission conditions.)
Easy-to-use cable connection type
External dimensions are approx. 125 (W) x 65 (H) x 35 (D) mm, and weight is 131 g (body only). In order to maintain operability of a camera, the WT-4 is not directly mounted on the camera bottom, but is connected via a cable.
A soft case that can be attached to a belt and a neck-strap are supplied as standard accessories.
With wireless LAN, IEEE 802.11b/g and 11a are supported. With wired LAN, IEEE 802.3u (100BASE-TX) and IEEE 802.3 (10BASE-T) are supported.
With wireless LAN, transmission range is approx. 180 m (IEEE 802.11b/g) and 260 m (IEEE 802.11a). (The range varies according to obstacles and radio wave conditions.)
Ad-hoc mode enables peer-to-peer connection of a WT-4 and a computer or FTP server. Infrastructure mode enables connection via an access point.
When the Nikon D3 or D300 is connected with the WT-4 via USB cable, several cameras can be wirelessly connected with a computer.
This mode permits thumbnail display of images taken with up to five wirelessly connected cameras on a computer display. Images selected by confirming the thumbnail can be downloaded and saved on the computer. With this mode, both photographer and computer operator can concentrate on their own assignment.
