DragonWave Inc., a supplier of packet microwave radio systems for mobile and access networks, on Tuesday at CTIA Wireless announced the availability of higher modulation modes of up to 2048 Quadrature amplitude modulation(QAM) on its Horizon packet microwave products. This higher modulation allows the radios to transport up to 37% more data through existing microwave channels, which improves spectral efficiency and, correspondingly, lowers operators' cost per bit.
When DragonWave (Ottawa, Canada) enables its Bandwidth Accelerator feature-a wire-speed bulk data compression technology- spectral efficiency is further enhanced 25% to 100% depending on traffic patterns.
Additionally, all Horizon packet microwave radios also support hitless adaptive modulation, allowing higher capacity delivery by the new modes when link properties permit-even on existing links that have been designed for lower modulation modes, says DragonWave.
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. Horizon Quantum can provide 2 carriers per radio each capable of 1024 QAM, delivering up to 2 Gbps in a single radio with Bandwidth Accelerator, says the company.
