If you have not heard about 4G yet, it is here now. Verizon has already paid earlier this year $9.4B for an open access to the new spectrum. It'll be using the spectrum as the core of their high-speed 4G LTE network - see below.
I predict, you will see many new designs (mobile, Wimax and base stations) addressing the new 4G standard. Every time, this is happening, companies need to develop new library of IPs, new platforms and therefore invest in design and verification. This is music to the ears of EDA companies and new fabless semiconductor companies.
Cadence and and Rohde & Schwarz announced last week a combined solution to enable early validation of next-gen 4G/LTE wireless design.
