3. C Q R Best Practices – Existing (Wireline) - -Battery = 8 hours for OSP (sufficient?) - -Generator - -Fixed Generators (typical 72 hours fuel) - -Portable Generators (DOT limits to ~200 gal transport w/o fuel trailer) Best Practices – Existing Technologies (Wireless) - -Battery = 2-4 hours (up to 8 hours) is cell site norm - -Generator (not at every sites) - -Fixed Generator at Critical Sites - -not typical at most Cell Sites - -Local Factors determine fuel storage (3 days fuel would be desired – not always doable) Best Practices – Data Centers (IDCs, Multi-tenant/Co-locations) -More typical AC environments with large UPSs -Dual commercial power sources is common - Generators: minimum is n+1, n+2, … Best Practices – Existing (Wireline) - -Battery = 8 hours for OSP (sufficient?) - -Generator - -Fixed Generators (typical 72 hours fuel) - -Portable Generators (DOT limits to ~200 gal transport w/o fuel trailer) Best Practices – Existing Technologies (Wireless) - -Battery = 2-4 hours (up to 8 hours) is cell site norm - -Generator (not at every sites) - -Fixed Generator at Critical Sites - -not typical at most Cell Sites - -Local Factors determine fuel storage (3 days fuel would be desired – not always doable) Best Practices – Data Centers (IDCs, Multi-tenant/Co-locations) -More typical AC environments with large UPSs -Dual commercial power sources is common - Generators: minimum is n+1, n+2, … IEEE COMMUNICATIONS SOCIETY List of Sources Session 3: Best Practice Combinations of Alternate Power Sources to Provide Optimum Duration
