NTT
DoCoMo to Launch Flat-Rate Internet Access Service "@FreeD"
for PHS
NTT DoCoMo, Inc., one of the largest mobile communication
companies in Japan, launched an always-on internet access service,
dubbed "@FreeD™", for use with compatible Personal
Handyphone System (PHS) terminals from April 1, 2003.
The new service, which offers @FreeD subscribers unlimited internet
usage, will be available in two packages. Users can pay a flat
monthly
fee of 4,880 yen or make an advance 48,000 yen payment for a one-year
subscription.
In this service NTT DoCoMo adopted "dormat mode" for the connection.
In this mode the connection goes into a "sleep" or "dormant" state
if no data is transmitted after a certain period of time or if
the
connection is weak. While in "dormant" state, the connection is
maintained without actively using a traffic channel on the network.
When the user needs to send or receive data, the connection is
automatically reactivated. Not only does this function help save
PC and PDA battery
life, data will continue being transmitted even if the user is
briefly out of the network area or will continue downloading from
the point
communication was disrupted. The transmission speed is 32kbps or
64kbps depending on the communication condition. (refer to "ARIB

new @FreeD compatible Compact Flash card-type PHS terminals, "P-in
Free™ 1P" and "P-in Free 1S," from April 1. The following
