MDM6200 and MDM6600 Mobile Data Modem User Guide Introduction
1.3.2 Memory support
Dual-memory buses separate the high-speed memory subsystem (EBI1) from low-speed memory
and peripheral devices (EBI2). The example application supports 160 MHz DDR SDRAM
memory on EBI1, and adds NAND or OneNAND™ memory via EBI2 (1.8 V devices). EBI2
memory is used for system boot.
1.3.3 Air interfaces
Multimode phones
The MDM6x00 device supports CDMA (1X, 1xEV-DOr0, 1xEV-DOrA, 1xEV-DOrB), WCDMA
(Rel ‘99, HSDPA, HSUPA, HSPA+) and GSM (Rel ‘99, GPRS, and EDGE). These enable rich
wireless multimedia services, such as high-speed upload of multimedia files and attachments,
interactive gaming, and a variety of IP-based services such as voice over internet protocol (VoIP).
Real-time conversation services such as push-to-talk, video telephony, and instant multimedia (an
extension of push-to-talk that combines immediate voice with simultaneous delivery of video and
pictures) are also supported.
Very high peak data rates are supported: up to 14.7 Mbps on the CDMA forward link and
5.4 Mbps on the reverse link; up to 14.4 Mbps on the WCDMA downlink and 5.76 Mbps on the
uplink. Such high data rates enable network operators to provide an even broader range of wireless
multimedia and other data services for consumers and enterprise customers. Data-only (DO),
HSDPA, HSUPA, and HSPA+ are optimized for packet data service and provide some of the
lowest costs per bit when compared with other wireless wide area network (WWAN) technologies.
The MDM6x00 solution integrates powerful applications processors into the Qualcomm
market-proven wireless modem, offering increased processing capacity combined with lower
power consumption. With this solution, handset manufacturers can design sleek, converged
consumer wireless devices that boast the industry’s most advanced image quality and resolution to
provide enhanced 3D animation, gaming, streaming video, videoconferencing, broadcast
reception, and more.
GNSS position location and navigation systems
Gen8 (GPS L1 + GPS L1 wide + GLONASS) is supported.
A global navigation satellite system (GNSS) is a satellite navigation system that provides
autonomous geospatial positioning with global coverage. The integrated GNSS functionality
allows the handset to determine its location (longitude, latitude, and altitude) to within a few
meters using time signals transmitted along a line-of-sight by radio from satellites.
Two examples of a GNSS is the fully functional United States NAVSTAR global positioning
system (GPS) and the Russian GLONASS, which is in the process of being restored to full
operation. The MDM supports both systems.
GPS consists of up to 32 medium-earth-orbit satellites in six different orbital planes, with the exact
number of satellites varying as older satellites are retired and replaced. It is currently the world’s
most used satellite navigation system. GLObal'naya NAvigatsionnaya Sputnikovaya Sistema
(GLONASS) currently has gaps in coverage, but is on its way to full global availability.
