Microwave Radio – Product Overview


Software Defined Radio 6-38GHz

Dantech Digital is offering a range of high performance microwave radios using licensed frequencies in the common 6-38GHz bands. Using advanced modulation techniques, mixed SDH, PDH and IP/Ethernet traffic up to 311Mbps capacity can be transmitted reliably. Microwave radio is an established technology used by telecommunication operators and organizations where quality of service is ensured through careful frequency and link planning. Dantech Microwave Radios are distinguished by high performance, advanced radio features and flexible reconfigurable network interfaces.

  • Resilience for Fibre links
  • Fast Roll-out & Temporary Deployment


Dantech Microwave radios are high performance, modern generation wireless networking platforms supporting mixed IP/Ethernet, SDH and PDH interfaces, operating from 3.5 to 38GHz frequency bands and payloads from 16 to 311Mbps. Software-Defined Radio enables in- service upgrades, remote configuration, low equipment costs. Dantech Microwave systems offer users maximum useful lifespan and minimal capital and operating expenditure (CAPEX and OPEX).
Advanced networking features in the Microwave IDU include scalable Ethernet capacities up to 311Mbps, SDH support and PDH switching to add/drop op to 160 E1 channels between “East”, “West” and “Front Panel” ports which radically reduces costs and increases flexibility in a modern cellular network operator network, with ring, star and mesh configurations. High availability configurations include 1+1 protection. Operating distances vary depending on local weather conditions, specifically link frequency and rain intensity. Planning for microwave wave spectrum use must take into account the propagation characteristics of radio signals at this frequency range. While signals at lower frequency bands can propagate for tens of miles, higher frequency microwave signals can travel only a few miles or less.
Higher frequency microwaves can permit more densely packed communications links, with very efficient spectrum utilization.



Flexible Modular System Configuration

Dantech Microwave radios feature a scalable, flexible Indoor Unit platform. Indoor units can be configured
with single or dual ODU uplinks for 1+1 resilient links or 2+0 repeater sites; Dual Redundant power
options; additional E1/T1 or SDH network modules. The modular design allows for future upgrade to
Gigabit Ethernet with the full 311Mbps available. The flexible “mix and match” choice of network
interfaces allows for any combination of:

  • 1-100 Mbps full duplex Ethernet (scalable to multiple rates)
  • 1-16 x E1/T1
  • 1-2 x STM-1 Electrical
  • 1-2 x STM-1 Optical / OC-3
  • Additional 1-16 x E1/T1 (for a total of 32x E1/T1)
  • STM1 to E1/T1 Mux/Demux integrated in a single 1RU SDIDU
  • Gigabit Ethernet (scaled)





Typical configuration examples include:

  • 100 Mbps full duplex Ethernet + 2 x E1/T1
  • 50 Mbps full duplex Ethernet + 16x E1/T1
  • 311Mbps full duplex Fractional Gigabit Ethernet + 2 x E1/T1
This flexibility is ideal in a modern service provider environment, handling mixed IP and TDM traffic, for
example GSM + 3G base stations, plus WiFi hotspot overlay.
The Dantech Microwave IDU works alongside a complete range of Outdoor Units (ODU) for various
frequency bands. The ODU determines the frequency band supported. Examples include:
