- | The physical (PHY) layer transmission technology of IEEE 802.3bz is based on 10GBASE-T, but operates at a lower signaling rate. By reducing the original signal rate to 1⁄4 or 1⁄2, the transfer rate drops to 2.5 or 5 Gbit/s, respectively.[4] The spectral bandwidth of the signal is reduced accordingly, | + | |

- | Power over Ethernet[edit] | + | |
- | Unlike the preceding 10GBASE-T standard, equipment manufacturers have indicated their intention to implement 802.3at type Power over Ethernet on certain types of NBASE-T switches. This implementation is intended to support high-bandwidth wireless access points (802.11ac | + | |

- | May 2015 was a landmark date for campus networks everywhere because that is when the Aruba 5400R Switch Series became the first switch to deliver multi-gigabit Ethernet technology. The HPE Smart Rate multi-gig modules brought higher speeds and PoE+ using existing wiring, simplifying migration by eliminating the need to rip and replace cabling. No longer are customers faced with the costs and complexity of upgrading wiring to achieve above 1GbE speeds because this innovative technology runs on widely used, existing CAT 5e cabling. Deploying these wired multi-gigabit ports today protects infrastructure investment because they support 1, 2.5, 5 and 10GbE speeds that mean that as new, faster devices such as APs become available, the wired infrastructure is ready to support with the fastest connection. This exciting technology, which brings more performance, | + | |
