Exalt: 1 Gbps Backhaul

Posted by Sam Churchill on

Exalt Communications today unveiled its newest microwave backhaul platform, ExploreAir. The new platform delivers 500 megabits per-second full-duplex Ethernet plus native TDM, and supports world bands from 2 GHz to 40 GHz.

Exalt claims ExploreAir delivers the industry’s highest throughput and longest range in the microwave and millimeter wave spectrum. The first ExploreAir systems, available now, come in compact, lightweight all-outdoor configurations. They feature adaptive modulation and integrated QoS, said to extend link distance, reduce antenna size, and dynamically allocate TDM and IP traffic on the same link.

Exalt’s product line includes the low cost ExtendAir, the mid-range ExploreAir and carrier-grade EX Platforms. ExploreAir systems are optimized for LTE and WiMAX backhaul, supporting bandwidth-hungry devices.

Exalt says ExploreAir delivers the highest value with the lowest cost per megabit-mile. The software defined front-end enables one unit to work in different bands with the field-replaceable diplexer reducing the cost of spares.

“To support 3G and 4G services, cell sites will need up to 300 megabits per-second of backhaul capacity to support subscriber demand, ” said Michael Howard, principal analyst and co-founder of Infonetics. The only way to deliver the promised 10+ megabits per-second of bandwidth to each user is to split the RAN infrastructure into much smaller cells, and each of these will need a new high capacity backhaul connection.”

Exalt microwave systems use the 18 GHz, 23 GHz, and 5 GHz frequencies to deliver Ethernet traffic over distances exceeding 20 miles. Exalt’s capacity aggregation is said to enable a full duplex, 1 gigabit per-second (Gbps) Ethernet transport. It drives Cruzio’s wireless Internet access business on both sides of the Santa Cruz Mountains.

Other wireless backhaul providers in the Gigabit/second space include Bridgewave, Ceragon, E-Band Communications, Gigabeam, Loea, Proxim’s GigaLink and Proxim Wireless, Alvarion, and Trango. They provide a wide range of licensed and unlicensed microwave solutions in a variety of bands for cellular, 4G or industrial backhaul.

The top 3 packet microwave vendors during the fourth quarter of 2009 were Dragonwave (37 percent), Alcatel-Lucent (30 percent), and Bridgewave (9 percent), according to market researcher Dell’Oro Group.
