Terminology
802.11 AdHoc (Peer to Peer) mode
This mode performs communication directly between the projector and a computer
with a built-in wireless LAN or a computer with a wireless LAN card mounted. The
SSID must be set.
Access point
A wireless station used to connect a wired LAN and a wireless LAN.
AdHoc mode
This mode performs communication directly between the projector and a computer
using built-in wireless LAN or a computer with a wireless LAN card mounted. The
projector and computer channel settings must be the same. Some cards do not
support this mode.
Channel
When multiple access points that use the same frequency band during communication
are installed near each other, radio wave interference may cause the communication
speed to drop. The frequency band can be divided into 14 channels for communication
to reduce this interference in a wireless LAN. (The number of channels differs
according to the country of use.) However, there is still some interference between
adjacent channels, so communication channels should be separated by 2 or 3
channels during actual use.
DHCP
Abbreviation for Dynamic Host Configuration Protocol. This function automatically
assigns IP addresses to the connected equipment. If a device with the DHCP server
function is present within a LAN, it automatically assigns IP addresses to the
connected equipment. This is not supported on the projector side.
Gateway
This is a relay point for connecting different networks.
This refers to the hardware and software used when connecting a network with a
network that uses a different protocol, etc. It adjusts the protocol and other differences
between networks to allow connection with other networks.
Infrastructure mode
This mode performs communication via an access point connected to a wireds LAN.
This makes it possible to transfer images to the projector through an access point even
from a computer without a wireless LAN card mounted.
IP address
Internet Protocol (IP) is a protocol for distributing data, and the address corresponding
to the data distribution destination is called the IP address. The same IP address
cannot be used within the same LAN.
