Industry’s first quad and dual stacked sub-carriers, now being deployed, are enabled by software licenses to support unprecedented actual throughput of 1.6Gbps on single transceiver (ST) and 3.2Gbps on dual transceiver (DT) Navigator radios

San Diego, California, Sept. 5, 2019BridgeWave Communications, a market leader in 5G wireless backhaul systems, today announced the availability of Navigator’s game-changing dual and quad stacked sub-carriers. Enabled by software licenses, Navigator’s stacked sub-carriers double radio capacity without compression or the need for any additional equipment. The Navigator ST single transceiver radio can now deliver up to 1.6Gbps per radio by carrying two stacked sub-carriers across a single transceiver, with bandwidth up to 112MHz per channel (2x112MHz). The Navigator DT dual transceiver radio can now deliver up to 3.2Gbps per radio by carrying four stacked sub-carriers across dual transceivers, with bandwidth up to 112MHz per channel (4×112 MHz). The Navigator DT radio system takes capacity even further, supporting XPIC with quad sub-carriers to provide 2 x (2+0 XPIC) operation in a single radio without requiring any additional hardware or external components and saving valuable spectrum. BridgeWave has already deployed in the US a Navigator DT stacked sub-carrier radio system carrying 2.25Gbps live traffic using 2×80 MHz channels in XPIC mode in a single radio, and is shipping quad carrier single radio systems to customers around the world, including to a Tier1 carrier. All new orders for Navigator systems support stacked sub-carriers.

The unique sub-carrier feature allows customers to purchase Navigator at the lower price single carrier per transceiver configuration, with the ability to upgrade to the dual carrier Navigator ST or quad carrier Navigator DT, and it eliminates the need for additional radio hardware and accessory products such as couplers and antennas, reducing tower leasing and installation costs. With Navigator systems, network operators have unprecedented flexibility to support multiple network configurations and applications, optimize networks for the highest capacity and range, upgrade legacy networks, and speed up deployments.

“We promised our customers that we would double their microwave link capacity at a fraction of the cost, significantly improving their ROI compared to traditional microwave solutions, and we have delivered on that promise,” said Sanjay Nagpal, senior vice president, global sales and marketing, REMEC Broadband Wireless Networks. “With Navigator stacked sub-carriers, our customers can dramatically increase network performance and ARPU, lower upfront capital investments, and reduce ongoing operating costs as they expand their backhaul networks to support their business goals and outdistance their competitors.”

Navigator’s other unique features include:

modulations up to 4096QAM with ultra-wide channel bandwidths up to 112MHz (ETSI) and 160MHz (ANSI) to maximize capacity and range;
customer-replaceable diplexers to minimize product lead times and inventory stocking costs;
the ability to support different frequencies in single dual transceiver radio (e.g. 6GHz and 11GHz);
flexibility to use each radio as a high band or low band unit, minimizing the need for sparing;
internal branching assemblies to allow for low cost single chassis XPIC, multi-channel, repeater, and protected radio configurations;
a dual 10GbE interface with radio link aggregation that enables simplified networking of multi-gigabit traffic and  single fiber connectivity to the customer site networking equipment;
integrated software features like ACM and QoS, eliminating the costs of additional software licenses, and simplifying radio configuration, installation, and support;
advanced Carrier Ethernet features including timing and synchronization, header and payload compression and several additional networking features, all enabled with a single software key;
adaptable antenna interface that allows operators to upgrade legacy networks with minimum investment and service disruption.

The demand for Navigator continues to escalate because the radio system minimizes upfront investment costs and the ongoing costs to modify, maintain, and service networks. Customer replaceable diplexers in Navigator simplify deployments whether or not customers know their desired frequency assignments at the time of planning and ordering. Navigator ST and DT can be ordered fully configured, or without diplexers installed and then equipped with diplexers as they are fielded. This greatly simplifies logistics for customers deploying modern multi-transceiver radios like Navigator that can carry up to four channels per radio; customers are no longer locked to a fixed radio configuration like traditional radio architectures.

BridgeWave backhaul systems increase backhaul network capacity without the hassles and costs of new or leased fiber. In addition to Navigator microwave systems supporting the 6-42GHz frequency bands, BridgeWave offers systems supporting the 70-80GHz frequency bands, including our flagship 80GHz system, the Flex4G-10000 delivering up to 10Gbps; Flex4G‑LITE, delivering up to 3Gbps; and the entry-level Flex4G-1000, delivering up to 1Gbps.
