Canada’s DragonWave Inc., a global supplier of packet microwave radio systems for mobile and access networks, has released higher-modulation modes of as much as 2048 QAM on its Horizon packet microwave products.
“This higher modulation allows the radios to transport up to 37-percent more data through existing microwave channels, which significantly improves spectral efficiency and, correspondingly, lowers operators’ cost per bit,” the company says. “When DragonWave’s unique Bandwidth Accelerator feature — the industry’s only wire-speed bulk data compression technology — is enabled, spectral efficiency is further enhanced 25 percent to 100 percent, depending on traffic patterns.” ??
Additionally, all Horizon packet microwave radios support hitless adaptive modulation, bringing operators higher-capacity delivery with the new modes when link properties permit, even on existing links that have been designed for lower-modulation modes. ??With 2048 QAM, “customers can achieve greater than 500 Mbps of transport in a Horizon Compact+ all-outdoor system and up to a gigabit with DragonWave’s Bandwidth Accelerator,” the company adds. “Horizon Quantum can provide two carriers per radio, each capable of 1024 QAM, delivering up to 2 Gbps in a single radio with Bandwidth Accelerator.” ?
