Thanks Eric for joining our SP Mobility Community and for your comments.
CPEs have historically followed the price/volume curve. Somewhat high during the formative days of a technology/solution and then, driven by tighter integration, greater interoperability, and higher volume, CPEs have offered more for less. Multi-vendor nteroperability between CPE and BTS (including interoperability for innovations such as beamforming, power management, etc.), and between base stations, will bootstrap this process, with some help from consortia such as WiMAX Forum (or LSTI for LTE solutions).
Are you aware of our USB CPEs for WiMAX? I also suggest you take a look at new revenue sources and business models and sources of revenue such as targeted advertising, parental control, fair usage, etc., to increase the ARPU.
