Semi-retired since 1999 when Vodafone acquired AirTouch, aka Verizon. Currently looking for the right position not just any position. In the meantime I've been analyzing 5G, LTE, UMTS, HSDPA, EvDo, CDMA, MIMO, Maxwell's equations, DAS and antennas. Calculated LTE, HSDPA, EvDo capacity, link budgets, codes, acquisition signals, code rates, etc... Currently looking for a permanent/consulting position in the Denver metro area. Will consider other locations based upon rate and benefits.
