Seven leading global mobile phone operators said on Thursday they had formed an organization to examine how broadband wireless technology might evolve beyond current 3G standards.

Leading mobile operators including China Mobile, KPN, NTT DoCoMo, Orange, Sprint Nextel, T-Mobile and Vodafone have joined forces to develop a common vision for mobile networks and technology that will take the industry beyond the HSPA and EV-DO roadmaps.

The Next Generation Mobile Networks (NGMN) initiative, which has this week become a limited UK company, has created a set of requirements for a future wide area mobile broadband network that is designed to offer enhanced customer benefits by delivering competitive broadband performance alongside high levels of interoperability.

The initiative, which will work alongside existing standards bodies, will seek to shape the development and standardisation of the next generation of mobile technologies. With a strong emphasis on practicality, the group has specified that the evolutionary path should focus on existing infrastructure and spectrum allocation, in order to develop a platform for creating new and innovative services.

Under its recommendations, the NGMN initiative has outlined a series of features that will help to guide mobile networks beyond current HSPA and EV-DO technologies while delivering competitive services in line with customer demand. The guiding principles include but are not limited to:

- High levels of data throughput alongside low levels of latency
- Low operation and maintenance costs
- Compatibility with legacy networks
- Support of high levels of authentication and security, and differentiated quality of service
- Improved terminal certification schemes
