3GPP Scout / Specifications
3GPP specifications: what each TS and TR covers and its newest versions
One short page per 3GPP specification: what it covers, quoted from its scope, its newest version in each release, and the change requests behind the newest one.
How these pages work
Each page has a facts box taken from the 3GPP archive and one short paragraph. Every quote is copied from the specification, checked word for word and linked to the original. A second AI model reviews every paragraph before it is published.
