Note: Model number E8887 has been discontinued; however, the HSPA (High-Speed Packet Access) Wireless Library feature/capability is now included in the W2364 2G/3G Cellular Libraries Element.

The information below is provided for reference only.

High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) are both available in the current version of the E8887 High Speed Packet Access Wireless Library. The HSDPA content is based on 3GPP FDD enhanced downlink defined in Release 6 of the 3GPP specification.

Product Description:
The High Speed Uplink Packet Access (HSUPA) wireless library is based on 3GPP FDD enhanced uplink, defined in release 6 of 3GPP specification. This design library focuses on the physical layer aspects of HSDPA/HSUPA systems and is intended to be a baseline system for designers to get an idea of what nominal or ideal system performance would be.

With the High Speed Downlink Packet Access (HSDPA) wireless library, there is only high data rate downlink capability. There are a number of benefits to a balanced downlink/uplink in 3G Cell Phone applications. For example, there are user applications that transmit large amounts of data from mobile station, such as a user sending a video clip or a business user sending a large presentation file. It is also beneficial to balance the capacity of uplink with the capacity of downlink for future applications such as Voice over IP.

For HSDPA content in this library, new physical channels: HS-PDSCH, HS-SCCH and transport channels: HS-DSCH plus uplink physical channel HS-DPCCH are added.
