Don’t Get Burned with Half-Duplex Capacity Claims
It is finally time to uncover the mystery between FDD and TDD, specifically the importance of FDD as a key element in network performance.
FDD stands for Frequency Division Duplex, and TDD stands for Time Division Duplex. Both FDD and TDD are two spectrum usage techniques, both forms of duplex, used in mobile or fixed wireless broadband links. It is essential to these links that transmission can occur in both directions simultaneously so that data can flow downlink (DL) and uplink (UL) at the same time without any noticeable interruptions.

Most operators of WISP backhaul networks have had difficult experiences with Power over Ethernet (PoE) cabling solutions, affecting both the economics and operations of their networks. Today, Aviat Networks is recommending, with increasing frequency, a dual cable system: fiber to carry data at high speeds, and copper to carry DC power only. This solution offers significant advantages over CAT5 cabling, which carries both data and DC power over a single Ethernet cable.
For new entrants and smaller WISPs, cost is often the major factor in infrastructure procurement. However, many WISPs who used to be in those categories are today enjoying significant growth, prompting them to rethink infrastructure investments as part of their overall business plan.
