The TD-HSDPA residential gateway for wireless broadband internet access is a product jointly promoted by the three parties. Amoi’s data card using Spreadtrum’s SC8800S is connected to Desay’s residential gateway device through a USB interface, offering TD-HSDPA wireless broadband internet access to the users. The SC8800S chip includes the same type of high integration as previous Spreadtrum baseband chipsets and also meets EDGE (EGPRS Class10) standard.
It is claimed that this residential gateway supports not only USB interface (for TD-HSDPA wireless access), but also Wi-Fi interface, fixed line interface RJ11 and LAN interface. Therefore, this product should facilitate the convergence of fixed and mobile communications with the internet.
TD-HSDPA is a new member in the HSDPA (high speed downlink packet access) family, which was announced by 3GPP (3rd Generation Partnership Project) to address the need of high-speed data transmission for multimedia service. TD-HSDPA is an extension of TD-SCDMA, supporting uplink synchronization, dynamic channel allocation and other features. As a result, TD-HSDPA provides better support for asymmetric data business.
Ping Wu, chairman and CEO of Spreadtrum, said: The TD-HSDPA residential gateway product uses Spreadtrum’s SC8800S chip solution. We believe that this cooperation not only provides residential customers with a product that supports both fixed line and mobile communication services, but also creates a new cooperation pattern to enhance the further development of TD-HSDPA business.
