Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
FilterSolutions™ and QuickFilter™ synthesis programs from Nuhertz Technologies introduce enhanced techniques for designing Hairpin Resonator or Ring Resonator filters. In conjunction with electromagnetic simulation tools from AWR Corp. and Sonnet Software, optimized cross-coupled circuits are used to minimize the use of circuit board space and narrow the passband.
TDK company EPCOS, a leading manufacturer of electronic components, modules and systems, and Pulse Electronics, a leading antenna manufacturer, used AWR’s Microwave Office to design indie, a breakthrough technology that answers the challenge from carriers in the Next Generation Mobile Networks (NGMN) Alliance to develop a single, operator-independent RF platform supporting all NGMN operator frequency bands.
A level of software synergy is essential when designing circuits for use in today’s wireless systems (third- and fourth-generation) that employ higher-order modulation techniques together with advanced technologies, such as orthogonal frequency division multiplexing (OFDM), multiple-input multiple-output (MIMO) and digital predistortion (DPD) circuits, to name a few.
