ExtremeAir: True Gigabit Microwave

Delivering Fiber Speed for Miles
Starting at under US$18,000 per link, ExtremeAir™ all-outdoor licensed band systems include the highest capacity radios in the ExtremeAir lineup, delivering higher per channel 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. ExtremeAir all-outdoor licensed systems offer:

  • Up to 1000 Mbps full-duplex guaranteed Layer 2 throughput - the world's highest single channel capacity available in sub-60 GHz bands
  • Hitless and jitterless adaptive modulation, fully configurable from QPSK to 256QAM
  • Built-in XPIC, enabling dual-carrier, single channel operation with a single antenna

ExtremeAir all-outdoor radios are currently available in the ANSI/FCC 11, 18 and 23 GHz bands. For immediate or future requirements in other bands, including LMDS and DEMS, please contact Exalt.

ExtremeAir systems support QPSK to 256QAM modulation in channel bandwidths of 30 to 80 MHz (FCC) and 14 to 56 MHz (ETSI). Three interface configurations are initially available to meet a wide range of deployment, application and migration scenarios:

  • ExtremeAir rcXX200 models: 1x10/100/1000BaseT (PoE)
  • ExtremeAir rcXX205 models: 1x10/100/1000BaseT (PoE) + 3x10/100/1000BaseT
  • ExtremeAir rcXX220 models: 1xDC + 2x10/100/1000BaseT + 1x1000BaseX(SFP)

        *XX denotes frequency, e.g. 11, 18, 23

Like all Exalt radio systems, ExtremeAir all-outdoor radios are fully software defined and software configurable, easily scaling their capacity. License key upgrades are used to augment base Ethernet capacity of 400 Mbps to 600, 800 or 1000 Mbps and to enable other optional capabilities. ExtremeAir all-outdoor licensed systems boast a wide variety of features:

FeatureDescription and Benefits
Built-in XPIC 
  • Enables dual-carrier operation in a single RF channel 
  • Simplifies licensing compared to other microwave systems requiring multiple channels
zero footprint 
  • At 17 lb / 7.7 kg, ExtremeAir minimizes visual impact and tower loading and maximizes installer safetyReduces deployment complexity
  • Cuts recurring lease expense
Hitless & jitterless
adaptive modulation
  • Fully programmable adaptive modulation settings
  • Ensures that the performance of any  traffic stream will be unaffected during modulation shifting
  • Enables sustained Layer 2 throughput up to 1 Gbps at 20+ miles
Native Ethernet
  • Ensures that the radio adds no additional packet delay, unlike systems that map 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
Four Gigabit Ethernet
ports (rcXX205)
  • 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
  • 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 four 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
  • 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

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

  • Mobile backhaul. The ExtremeAir all-outdoor licensed systems are ideal for backhaul aggregation nodes and high speed rings in LTE networks. The zero footprint, single mounting point design minimizes site capital and lease costs. ExtremeAir can simultaneously support the latency requirements of 2G voice traffic and the growing capacity requirements from 3G and 4G data traffic.
  • IP backhaul. As service providers and private network operators build, grow and re-architect their networks to accommodate greater volumes of data traffic, ExtremeAir is the most cost-effective means available of rapidly delivering the gigabit Ethernet capacities now often required ring, aggregation and backbone sites. ExtremeAir's zero footprint form factor minimizes site costs, while upgradeable capacity provides pay-as-you-grow CAPEX deferral.
  • Fiber extension. Many enterprise campus and critical infrastructure networks require fiber speed connectivity. Point-to-point ExtremeAir links deliver fiber performance using a familiar all-outdoor form factor and can be deployed far more inexpensively and rapidly than fiber. 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.
