PC300 Communications Summary
Your Sony Ericsson PC300 Mobile Broadband PC Card keeps you in touch, enabling you to use the
best available mobile service wherever you are. It supports tri-band UMTS and quad-band GSM:
Your PC300 supports the following communications services:
Where UMTS service with HSDPA is available, your PC300 can connect at speeds up to 3.6Mbps.
Your PC300 provides automatic fallback to to UMTS where HSDPA is not available and to EDGE
or GPRS service where UMTS is not available (network support required). This section describes
the services that the PC300 supports:
• High Speed Downlink Packet Access (HSDPA)
HSDPA is an enhancement to UMTS networks which enables the downlink speed to
be dramatically increased; up to 3.6Mbps using the PC300. File downloads will be faster,
whilst applications such as video streaming may operate at higher quality and greater
reliability. The maximum speed available depends on the configuration of the mobile
network and local conditions such as distance to the base station.
• Universal Mobile Telecommunications System (UMTS)
UMTS is a 3G technology standard for wide-area wireless data communication that is based
on the GSM standard. The UMTS standard uses advanced network operator mobile Internet
services to achieve data transfer rates up to 384 kbps, which are ideal for media streaming,
video MMS, instant shopping, and banking.
