: Some humanitarian and medical units in Iraq are using this self-organizing IP network to communicate in the field. The radios have a 40-mile radius and are typically mounted in humvees. "The Enhanced Position Location Reporting System (EPLRS) provides Marine Forces with a critical command and control tactical data distribution network. EPLRS links the dynamic Marine Air-Ground Task Force (MAGTF) Command, Control, Communications, Computers, and Intelligence (C4I) tactical data system architecture with a robust, user-transparent, automatic relaying, and automatic rerouting communications network." 6:06:22 PM
Low power windows terminals
: This study and another from wyse,
both in 3Q 2001, provide some info:
- winterm unit only: 8 watts
- add lcd screen: add 18 watts, 26 watts total
- CRT is 85 watts instead of 18 (the first study has 85 vs 29)
- PC is 85 watts instead of 8 (the first study has 70 vs 10)
- A terminal server PC is 100-140 watts, perhaps 5-10 users.
Certainly 3x-4x lower consumption with an LCD instead of CRT (no surpise there), and 7x-10x less for winterm versus PC assuming some server is needed anyway(again, no surprise for smaller power supply and no fan or disk). With one server per 8 users, the advantage of winterm vs standalone PC is about 3x. 12:03:26 AM
