3GPP Standards

IPWireless equipment is built on and complies with the 3G Project Partnership (3GPP) UMTS TD-CDMA standard.

3GPP is the international standards body that develops, publishes and maintains standards for third generation wireless. It is made up of the standards bodies in each of the major countries - T1 (US), ETSI (Europe), ARIB (Japan), ETRI (Korea) and CWTS (China). As well as the standards bodies, 3GPP is attended by all of the major technology companies.

The 3GPP family of standards consists on 3 alternative air-interface (physical layer) standards, which all share higher layer protocol stack and core network / back office architecture. These air-interface standards are FDD W-CDMA, High Chip Rate UMTS TD-CDMA, and low chip rate TD-SCDMA.

IPWireless has chosen to implement the UMTS TD-CDMA branch of standard, for the following compelling reasons:

It is the branch of the 3GPP standard specifically intended for high data rate services
The burst structures defined in the standard are designed to support advanced signal processing, which IPWireless implements to achieve exceptionally high performance (joint detection / advanced multi-user-detection)
Wide channels (5 and 10 MHz are supported), permitting higher data rates
"Shared channels" are supported in the standard. This is essential for achieving high throughputs with broadband packet data, through efficient on-demand assignment of resources

The standard permits interoperability between UE and network infrastructure from multiple vendors, providing the competitive market that will drive down costs and increase innovation, particularly on UE. Furthermore, standard interfaces between network elements are defined, permitting interoperability of different vendors.

A key benefit of using an international standard is the economies of scale resulting from the huge international market for the 3GPP standards, and from the fact that IPWireless has a high volume international market through the regulatory acceptance of 3GPP standards in virtually all major countries.
