Precautions/Specifica
tions
Router
A device that bridges networks,
converting the protocols and
addresses of each network. Recently,
dial-up routers for connecting to
ISDN lines and broadband routers
for ADSL and CATV networks have
been introduced. The term “router”
by itself may refer to any of these
devices.
S-IWS
S-IWS is an abbreviation of Sony
Instant Wireless Audio Setup. Instant
(S-IWS) connection allows you to set
up a wireless network easily.
SSID
Abbreviation of Service Set
IDentifier. It is a name that identifies
a particular access point within
an IEEE 802.11 wireless LAN. To
connect with an access point, a
client device must be set with the
same SSID. SSIDs can be up to 32
characters long. For higher security,
a network key is normally also used.
In this case, connection cannot
occur unless the SSID matches the
network key.
USB storage
In this manual, USB storage refers
to a mass storage device that
supports the USB Mass Storage Class
standard. These devices, such as a
USB audio player, can be connected
to the USB jack on the unit or a
computer and used as a removable
mass storage device.
WEP
Abbreviation of Wired Equivalent
Privacy. An encryption key used
in wireless LAN networks. As an
IEEE standard based on the RC4
algorithm cryptography, WEP is
used to secure IEEE 802.11b wireless
networks. During the transmission
of a message between a wireless LAN
access point and a client device,
the sending side encrypts the data
and the receiving side decrypts it.
For communication to occur, both
devices must use a common code
key, which is called the “WEP key”.
The encryption level is indicated by
the bit count of the key; e.g., 64 bits
or 128 bits. The higher the bit count,
the higher the security level.
WMA
Abbreviation of Windows Media
Audio. WMA is the audio
compression technology developed
by Microsoft Corporation that allows
audio files to be compressed to about
1/22 of the data size of a standard
compact disc.
WPA
Abbreviation of Wi-Fi Protected
Access. An encryption standard
for wireless LAN networks created
by the Wi-Fi Alliance to remedy
a number of serious security
problems in the WEP system. In
addition to the network name (SSID)
and encryption key (WEP), this
protocol uses a user authentication
framework called “EAP” (Extensible
Authentication Protocol) and a
protocol called “TKIP” (Temporal
Key Integrity Protocol) which
automatically updates the encryption
code at regular intervals for higher
security.
WPA2
Abbreviation of Wi-Fi Protected
Access 2. An encryption standard
for wireless LAN networks. As an
upgraded version of WPA created
by the Wi-Fi Alliance, this standard
uses AES (Advanced Encryption
Standard) cryptography to provide
stronger security than WPA.
DAB (Digital Audio
Broadcasting)-related
terms (UK model only)
Dynamic label segment
The text data transmitted for each
channel or service.
Ensemble label
In DAB, multiple digital radio
channels are transmitted using
a single radio transmission or
frequency. A group of channels sent
this way is called an “ensemble” and
“ensemble label” is the name of such
a group.
Service label
The name of an individual digital
radio channel or service.
