ExploreAir: Redefining the Licensed Backhaul Landscape

Delivering an Unmatched Combination of Speed, Distance, Cost and Time-to-Market
Starting at under US$10,000 per link, ExploreAir® all-outdoor licensed band systems include the highest capacity radios in the ExploreAir lineup, delivering higher per carrier throughput over greater distance than any radio in the world, providing far greater deployment flexibility than millimeter wave systems and far faster time-to-market than fiber. ExploreAir all-outdoor licensed systems offer:

  • Up to 740 Mbps full-duplex uncompressed Layer 1 throughput - the world's highest single-carrier, single channel capacity available in sub-60 GHz bands
  • Field-replaceable diplexers that allow single-unit sparing for an entire band, reducing the cost of spares by 50% to 90% compared to split-mount or other all-outdoor systems
  • The industry's highest system gain (ExploreAir HP, ExploreAir LR), enabling ultra-long links and dramatic antenna CAPEX and OPEX savings
  • XPIC readiness (ExploreAir LR) for quick and easy capacity doubling up to wire speed (1 Gbps) in a single channel

ExploreAir all-outdoor radios are currently available in the ANSI/FCC 6, and 11 GHz bands as well as the ITU/ETSI 11 GHz band.

ExploreAir systems support QPSK to 512QAM modulation in channel bandwidths of 10 to 80 MHz (FCC) and 7 to 56 MHz (ETSI). Multiple interface configurations are available to meet a wide range of deployment, application and migration scenarios:

  • ExploreAir LR rcXX150 models: 1x10/100/1000BaseT (PoE) + 1x1000BaseX (SFP)
  • ExploreAir / ExploreAir HP rcXX100 models: 1x10/100/1000BaseT (PoE)
  • ExploreAir / ExploreAir HP rcXX105 models: 1x10/100/1000BaseT (PoE) + 2x10/100/1000BaseT
  • ExploreAir / ExploreAir HP rcXX110 models: 1x10/100/1000BaseT (PoE) + 4xT1/E1

*XX denotes frequency, e.g. 11

Like all Exalt radio systems, ExploreAir all-outdoor radios are fully software defined and software configurable, easily scaling their capacity and dynamically allocating traffic between Ethernet and TDM (rcXX110 models). License key upgrades are used to augment base Ethernet capacity of 100 Mbps to 200, 300, 400, 500 or 600 Mbps and to enable TDM interfaces and other optional capabilities. ExploreAir all-outdoor licensed systems boast a wide variety of features:

FeatureDescription and Benefits
Field-replaceable diplexer
  • Enables a single ExploreAir unit to spare an entire band (e.g. 23 GHz), cutting the cost of spares by 50% to 90% versus other all-outdoor or split-mount systems
  • Can reduce radio lead times from weeks to days
Ultra-compact, zero footprint
  • At 8.2 lb / 3.6 kg, ExploreAir minimizes visual impact and tower loading and maximizes installer safety
  • Reduces deployment complexity
  • Cuts recurring lease expense
Ultra-high system gain (ExploreAir HP and LR)
  • Industry-leading system gain – at high modulation – ensures the lowest cost per Mbps mile
  • Dramatically reduces antenna-related capital and recurring costs
  • Can be adjusted by the user to optimize for longest range, smallest antennas or highest throughput
XPIC-ready (ExploreAir LR)
  • Addition of a second, connected terminal enables capacity doubling in a single channel
  • Allows for wire speed operation (1 Gbps) using a single antenna, minimizing deployment cost
  • Can be configured with two separate data streams for redundancy or a single Gbps stream using Exalt Layer 1 capacity aggregation technology
Hitless & jitterless adaptive modulation
  • Fully programmable adaptive modulation settings from QPSK to 512QAM
  • Ensures that the performance of any traffic stream will be unaffected during modulation shifting
  • Enables practical use of peak uncompressed throughput up to 740 Mbps
Data compression
  • Proprietary compression mechanisms can be applied to the data stream, improving throughput by as much as a factor of 2
  • Compression factor depends on mix of compressible and non-compressible traffic
Native Ethernet
  • Ensures that the radio adds no additional packet delay, unlike systems that encapsulate Ethernet over TDM
  • Allows ExploreAir to offer < 100 μsec latency over Gigabit Ethernet at full throughput
  • Allows sustained throughput independent of packet size or traffic loading conditions
Native TDM (rcXX110)
  • Users can migrate from TDM to IP/Ethernet at any time without new investment and without stranded capacity
  • Ensures low latency, circuit-switched performance for TDM connections
  • Maximizes radio channel efficiency by avoiding overhead associated with circuit emulation protocols
Fiber/SFP data interface (ExploreAir LR)
  • Supports cable runs > 100m
  • Eliminates need for separate power supply – accepts DC power over coaxial cable
  • Provides highest resistance to lightning and electromagnetic interference
Three Gigabit Ethernet ports (rcXX105)
  • Enables on-tower hub aggregation, in which a single ExploreAir can aggregate two last mile links without an external switch
  • Allows for direct switching of traffic from two IP devices or repeater configurations without the use of an external switch
  • Reduces hardware costs for cable runs, surge suppressors and switches (depending upon application requirements)
Advanced data networking
  • QoS (802.1p) featuring 8 priority levels and 8 individual queues provides a high degree of flexibility for traffic classification
  • Data ports can be assigned and managed using VLAN IDs (802.1q) with additional port-specific Ethernet rate limiting
  • Administrators can choose from a variety of classification mechanisms: 802.1p bits, IPv4 TOS or DiffServ, IPv6 traffic class, VLAN ID, source MAC address and destination MAC address
  • Up to three GbE ports and a built-in layer 2 switch support any network configuration and minimize the need for external devices
High security
  • Available 128-bit and 256-bit AES provide the highest level of data security available, meeting stringent NIST FIPS 197 standards
  • Hardware-based encryption ensures that latency and throughput are unaffected when data is running over an encrypted link
  • Management traffic security can be assured through use of encrypted SNMPv3 or secure socket layer (SSL/SSH)
Advanced spectrum diagnostics
  • A spectrum analyzer is built into every ExploreAir radio
  • Simplifies site surveys, aids in antenna alignment, installation and RSL optimization
  • Can be used for swift troubleshooting and recording of interfering signals
  • Useful tool for ongoing, remote system maintenance

ExploreAir All-Outdoor Licensed System Applications
ExploreAir is designed to serve a wide range of Ethernet/IP and TDM applications, including:

  • Mobile backhaul. The ExploreAir all-outdoor licensed systems are ideal for backhaul of high capacity edge RAN nodes that include any mix of 2G, 3G and LTE as well as for Ethernet aggregation points and ring sites common to 4G network architectures. The zero footprint design minimizes site costs while single-unit sparing keeps inventory costs to a minimum. As the only radio in the category that transports TDM natively (no protocol conversion required), ExploreAir can simultaneously support the latency requirements of 2G voice traffic and the growing capacity requirements from 3G and 4G data traffic.
  • IP backhaul. As wireless ISPs, WiMAX operators and private network operators grow and re-architect their networks to accommodate greater volumes of data traffic, ExploreAir is the most cost-effective means available of rapidly delivering high Ethernet capacity over backbone, ring and mesh networks. ExploreAir's zero footprint form factor minimizes site costs, while upgradeable capacity provides pay-as-you-grow CAPEX deferral. Field-replaceable diplexers dramatically reduce the number of spares required, further reducing overall deployment costs.
  • Campus connectivity. As WLANs migrate from 802.11g to 802.11n, capacity requirements for building-to-building and campus-to-campus traffic increase significantly. Point-to-point ExploreAir links deliver fiber-like performance using a familiar all-outdoor form factor and can be deployed far more inexpensively and rapidly than fiber. Support for native TDM ensures toll-quality voice while QoS, VLAN and rate limiting allow network policies to easily extend across the link, while ensuring the quality of latency-sensitive applications such as VoIP and video.
  • Video Surveillance. As video surveillance networks grow in scope and camera resolution increases, surveillance networks require higher capacity backhaul to carry traffic from cameras and, in some cases, mesh nodes back to a monitoring control center. ExploreAir is ideally suited for carrying these high traffic volumes while conforming to the all-outdoor paradigm common to these deployments.
