Ad-hoc: Devices in an ad-hoc wireless network communicate directly (“peer to peer”), without a wireless access point.

AES (Advanced Encryption Standard): An encryption standard developed for use by the American government. AES has been praised for combining strong encryption with rapid processing.

Auto IP (APIPA—Automatic Private IP Addressing): Allows devices in a network to automatically assign themselves unique IP addresses if no DHCP server is found on the network. Auto IP uses addresses from 169.254.1.0 to 169.254.254.255 and a sub-net mask of 255.255.0.0. These addresses are neither global nor private but are reserved for Auto IP.

BSS-ID (Basic Service Set ID): All wireless devices on an ad-hoc wireless network share the same BSS-ID. The BSS-ID may be up to thirty-two characters long and is case sensitive. See also Ad-hoc.

Channel: When multiple wireless LANs with different ESS-IDs are operating on a single frequency within a given area, transmission speeds will drop. Specifying a separate channel (frequency) for each network can prevent interference and increase transmission speeds (note that all devices in the same network must be set to the same channel). In the IEEE 802.11a standard, the 5 GHz band is divided into 19 channels, each separated by 20 MHz. In the IEEE 802.11b/g standard, the 2.4 GHz band is divided into 14 channels, each separated by 4 MHz.

DHCP (Dynamic Host Configuration Protocol) Server: Each device in a TCP/IP network requires an IP address. If a DHCP server is present on the network, IP addresses will be assigned automatically.

DNS (Domain Name Server): A server that contains a database of IP addresses and host names for the machines it administers and that converts host names to IP addresses in response to queries from clients. Each DNS can also query other Domain Name Servers for addresses not listed in its database.

ESS-ID (Extended Service Set ID): Multiple BSSs can be configured to form an ESS, allowing users to roam between wireless access points. Only devices with the same ESS-ID as a given access point can communicate with that access point. The ESS-ID may be up to thirty-two characters long and is case sensitive.

Ethernet: The name given to the IEEE 802.3 LAN standard. Devices in an Ethernet network are connected via UTP cables for transmission speeds of up to 10 Mbps (10 base-T) or 100 Mbps (100 base-TX).

Gateway: A network node that acts as an entrance to another network, for example between a company network and the Internet.

WT-4 specifications

The Nikon WT-4 is a powerful wireless transmitter designed specifically for use with Nikon professional DSLRs. It provides photographers with enhanced connectivity options, allowing them to transfer images quickly and efficiently, making it an essential tool for photographers who require seamless communication and robust performance.

The WT-4 supports both wireless and wired transfer capabilities, allowing users to tailor their setup to suit various shooting environments. With support for IEEE 802.11b/g wireless standards, the WT-4 can connect to standard Wi-Fi networks, enabling easy image transfer to a computer or directly to the internet. This feature is particularly useful for event photographers and those working in remote locations who need to deliver images promptly.

One of the standout features of the WT-4 is its ability to connect multiple cameras simultaneously. Users can set up a network of cameras, which can be useful for multi-camera shoots or events where images need to be captured from various angles. This capability enhances workflow efficiency and allows for a more synchronized photography experience.

The transmitter also features a USB port for direct wired connection to a computer. This provides an alternative transfer method, ensuring versatility depending on the photographer's needs. The WT-4 includes a built-in web server, allowing users to control the camera remotely via a web browser, which can be particularly helpful for capturing wildlife or candid moments without being present.

With its robust design, the WT-4 is built to withstand the rigors of professional use. It is constructed to provide durability while remaining lightweight, ensuring it does not add unnecessary bulk to the camera setup. The device is compatible with various Nikon cameras, making it a valuable addition for photographers who rely on Nikon's ecosystem.

In terms of power, the WT-4 is equipped with an internal rechargeable battery, providing a convenient solution for extended shooting sessions. The battery life is optimized to ensure that photographers can focus on their work without worrying about frequent recharges.

Overall, the Nikon WT-4 is an essential accessory for professional photographers looking for reliable wireless connectivity. Its combination of ease of use, dual transfer methods, and advanced features make it an indispensable tool for capturing and sharing high-quality images in real-time. Whether you're shooting a wedding, a wildlife documentary, or an art project, the WT-4 enhances your ability to streamline the photography process.
