Long-term evolution (LTE) and WiMAX technology do not qualify as 4G technology, a leading telecoms body has ruled.
The International Telecommunication Union (ITU) has reiterated its initial findings and confirmed that UK broadband providers should refer to both technologies as 3G.
In order for a network to be 4G, it must be able deliver a peak download speed of up to approximately 100Mb in a high mobility environment, and up to 1Gb in a low mobility equivalent.
Since neither LTE or WiMAX meet this criteria, they cannot be classified as fourth-generation communications, reports ISPreview.co.uk.
The news provider has forecast that 4G innovations will be seen in both fields over the coming years, however, regulation will prevent LTE broadband from asserting its presence for the next two to three years.
WiMAX, which stands for Worldwide Interoperability for Microwave Access, currently has the potential to provide fixed broadband speeds of up to 40Mb.
