PoE and n WLAN
802.11n AP needs more power !
802.11n AP needs Gigabit !
Since 802.3af power-over-Ethernet is not sufficient for many new n APs (assuming at least 2 antennas and RF chains at 5 GHz, a dual-radio AP will draw at least 15W*), at PoE is needed to support n installations
*Some AP offer 802.3af powering option but usually with reduced functionality

3. PoE landscape – When to use a Switch vs a Midspan
Outdoor installations
Require full-power per port
Require triple redundancy
PowerDsine 802.3af Midspans
Desire plug ‘n play installation
Need more ports over time – adaptable network
Looking for lowest TCO
PowerDsine single or multiport 802.3af
Need Management for remote reboot or device scheduling

5. Power Savings with Scheduling
Enterprise/Campus WLAN
Working hours:
7: :00 Monday to Friday
AP Consumption: 12.5W (load agnostic)
Yearly power consumption no scheduling:
12.5W x 24 hours x 365 days = 110 KWh
Yearly power consumption w/scheduling:
12.5W x 13 hours x 250 days = 41 KWh
Savings: 138KWh/year
€0.1/KWh* = €7.9/year per WLAN AP
* Source: Europe’s Energy Portal
Business case example:
240 AP’s = €1,656/year savings
ROI in 1/year
Midspan life-cycle: 10-years (lifetime-warranty)
Midspan return: 9x€1,656 = €14,904
