R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They
also have a 128-byte page programming function to make their write operation faster.
Note: Renesas Technology鈥檚 serial EEPROM are authorized for using consumer applications such as
Cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology鈥檚
sales office before using industrial applications such as automotive systems, embedded controllers,
and meters
General packet radio service (GPRS) is a packet oriented mobile data service available to users of the 2G Cellular communication systems global system for mobile communications (GSM), as well as in the 3G systems. In the 2G systems, GPRS provides data rates of 56-114 kbit/s.

In recent years, Cellular voice networks have transformed into powerful packet-switched
access networks for both voice communication and Internet access. Evolving Universal
Mobile Telecommunication System (UMTS) networks and first Long Term Evolution
(LTE) installations now deliver bandwidths of several megabits per second to individual
users, and mobile access to the Internet from handheld devices and notebooks is no
longer perceived as slower than a Digital Subscriber Line (DSL) or cable connection.
Bandwidth and capacity demands, however, keep rising because of the increasing number
of people using the networks and because of bandwidth-intensive applications such as
video streaming. Thus, network manufacturers and network operators need to find ways
to continuously increase the capacity and performance of their Cellular networks while
reducing the cost.
During the past years, there has been a quickly rising interest in radio access tech-
nologies for providing mobile as well as nomadic and fixed services for voice,
video, and data. The difference in design, implementation, and use between
telecom and datacom technologies is also getting more blurred. One example is
Cellular technologies from the telecom world being used for broadband data and
wireless LAN from the datacom world being used for voice over IP.
This book provides technical information about all aspects of 3GPP LTE. The areas
covered range from basic concepts to research-grade material, including future
directions. The book captures the current state of 3GPP LTE technology and serves
as a source of comprehensive reference material on this subject. It has a total of
12 chapters authored by 50 experts from around the world. The targeted audi-
ence includes professionals who are designers or planners for 3GPP LTE systems,
researchers (faculty members and graduate students), and those who would like to
learn about this field.
