A modular device for providing network access in accordance with at least two radio access technologies is described. The device includes a first hardware module comprising a first hardware accelerator adapted to perform at least layer (1) processing in accordance with a first radio technology, software-controlled processing resources adapted to perform at least layer (2) processing for the first radio access technology and for a second radio access technology, and a first interface adapted to couple the software-controlled processing resources to a second hardware module providing at least layer (1) processing capabilities in accordance with the second radio access technology. The second hardware module may comprise a second hardware accelerator adapted to perform at least layer (1) processing in accordance with the second radio access technology and a second interface adapted to couple the second hardware accelerator to the first interface of the first hardware module.
