The document discusses strategies mobile operators can take to develop mobile broadband (MBB) networks. It outlines challenges like managing the optimization curve of ARPU, bandwidth, and costs. It proposes using LTE to reduce costs per bit and hosting new services. It also recommends an end-to-end solution to protect margins through single-RAN architecture, refarming spectrum, and improving spectrum efficiency.
