1. What data options does
the Nokia 7250 have and what are the data speeds?
The Nokia 7250 supports CSD (Circuit Switched Data), HSCSD
(High-Speed Circuit Switched Data) and GPRS (General Packet
Radio Service). CSD (GSM data) works in conventional GSM
networks, and data transmission speeds range from 9.6
kbps to 14.4 kbps.
HSCSD speeds are up to 43.2 kbit/sec (3+1/ 2+2). The supported
connection methods are analog, ISDN v110 and ISDN v120.
The difference compared to GPRS is that the circuit connection
is left open and the throughput level is then stable in
the GSM network.
The peak bit rate of the Nokia 7250 GPRS phone is 40.2
kbps with three time slots, which is more than enough
for most of the current and near future WAP services.
There are four different Coding Schemes, and Nokia terminals
support CS1, CS2, CS3 and CS4. Transmission speed is also
affected by the available network resources. The Nokia
7250 supports multislot class 6, which enables 3+1 and
2+2 (receiving/sending) connection and is optimal for
browsing and downloading.
3. Why does the product name start
with a seven when all the previous Nokia Fashion products
have started with eight (8310, 8210, 8250)?
Product names give some guidance of the product positioning.
For Fashion phones, we have evaluated the 7000 series
as
being more adequate. It doesn't have any reference to
the earlier Nokia 7110 product.
6. What does ''World Phone,'' triple
band EGSM 900/GSM 1800/1900 actually mean?
The Nokia 7250 can operate in these three different GSM
networks, which essentially means that it can be used
on all five continents where these networks are supported
- EGSM 900 and GSM 1800 are supported in Europe & Africa,
APAC and Brazil, and GSM 1900 is supported in the Americas.
7. I hear people talk about SAR
figures. What does SAR mean?
SAR stands for Specific Absorption Rate, which is a measure
of the amount of radio wave energy absorbed by the body
when using a mobile phone. Scientifically based international
recommendations and standards are in force governing the
maximum levels of SAR. All Nokia products are designed
to comply with relevant recommendations and standards.
More information can be found in the User's Guide included
in the Nokia 7250 sales package and from www.nokia.com.
