Upgrading Dragonwave Microwave Links

Why consider upgrading Dragonwave Microwave Links ?

Many users consider upgrading existing Wireless Links such as Dragonwave to add greater capacity, or network coverage.  When considering a wireless vendor, factors generally include:

  • Vendor Track Record
  • Vendor Corporate Stability
  • Product Performance & Reliability
  • Product Support and Service
  • Manufacturing Leadtimes
  • Attractive Vendor Roadmap
  • Product Pricing including all required options

Generally, Microwave links are required to operate unattended for many years in challenging outdoor environments, and therefore reliable and stable products and vendors are paramount in the selection process.

Turbulence in Wireless Vendor Market Space

Amongst many ongoing changes in the market for Microwave Backhaul and Microwave Transmission vendors, there is ongoing consolidation, M&A, and other activities.  Recently, Packet Microwave Vendor Dragonwave recently underwent receivership and buy-out by Transform-X.

According to RCR Wireless article dated 3 August 2017,

Once a significant player in the microwave backhaul space, Ottawa, Canada-based company DragonWave has effectively shutdown, with the Ontario Superior Court of Justice placing a financial receiver in charge of the firm’s “property, assets and undertakings.”

With assets sold by the Receiver to Transform-X, and the Dragonwave business is no doubt being reshaped by the new owners of the business.

CableFree FOR3 Full Outdoor 1024QAM Microwave Link - Upgrade Dragonwave
Full Outdoor 1024QAM Microwave Link from CableFree

Upgrade to Latest Microwave Technology for Higher Capacities

Some vendors are fully shipping products today with 1024QAM, XPIC, and upgrades to 2048QAM, XPIC, 10Gbps MMW (Millimeter Wave), which are features above and beyond those achieved by many in the market today.  Customers can upgrade today and achieve higher capacity, longer range, reach and availability, at low Total Cost of Ownership compared to competing options.

Future Roadmap for Microwave Upgrades

In addition to today’s products, an impressive roadmap ensures access to higher speed links and features in future products also.   Consideration is worthwhile into:

  • Vendor roadmaps to higher capacity links with microwave up to 4Gbps or more per link existing today.
  • Upgrading to E-Band MMW for shorter links especially in congested city environments
  • Using E-band Millimeter Wave for short links to free-up existing microwave spectrum, relief of spectral congestion and re-using valuable microwave spectrum for longer links where required

Microwave Links power ISP backbones in the Middle East

Implementing Microwave for High Speed Internet ISP Backbones in the Middle East

CableFree FOR3 Microwave links are being installed by ISPs in Iraq for Internet Backbone Connectivity. These links offer 880Mbps full duplex capacity with easy upgrade capability to 2+0 for 1.76Gbps full duplex, and are typically installed on towers or buildings for clear Line of Sight between network node locations.

1024QAM Microwave Links

1024QAM Microwave Links for High Capacity Wireless Transmission

High Capacity Microwave Links from leading vendors use 1024QAM modulation to achieve high capacity, spectral density and efficiency without sacrificing reliability.  This technology sets a new benchmark for microwave transmission capacity for operators including 4G / LTE Backhaul links for mobile operators as well as last-mile links, backbone and other applications.

High Capacity Links require High Order QAM modulation

CableFree Microwave 1024QAM increase from 4QAMLeading long-haul microwave equipment vendors are now using dependable long-distance transmissions using 1024 QAM. Relative to the industry-standard 256 QAM, this represents a 25% increase in capacity (and up to double the capacity of legacy SDH links), with all other factors the same. Compared to older 4QAM modulation the increase to 1024QAM is five-fold. Operators of long-haul microwave links will certainly enjoy the boost to their capacity with 1024 QAM, especially when these upgrades are relatively painless and generally require only a minor and quick swap of equipment.

Adaptive Coding and Modulation (ACM)

ACM with 1024QAM ModulationLeading microwave equipment vendors are able to keep their long-haul transmission links operational even in transient fade and noisy conditions. The enabling technology is ACM: Adaptive Coding and Modulation. Microwave links with ACM technology automatically sense the quality of the transmission link and can automatically decrease the modulation technique in case of degraded signal quality due to interference or other microwave propagation problems such as weather. So, if a microwave transmission is operating at maximum capacity using 1024QAM and suddenly encounters interference or high rainfall, a system such as the CableFree microwave system automatically steps down the modulation to lower levels until the transmission network, although at lower capacity now, maintains the ultra high level of link reliability and availability. As the temporary weather effects disappear, the microwave system automatically re-applies more efficient higher-order modulation techniques to regain full capacity.

Overcoming Tradeoffs due to High Order QAM Modulation

CableFree 1024QAM modulation tradeoffsWith increasing modulation the receiver sensitivity is greatly reduced, and generally transmit power has to be reduced due to linearity constraints in the transmitter.  For fixed modulation speeds the result is either increase of antenna size or reduced distances, which may prevent an operator upgrading to higher capacity.  The use of ACM allows use of 1024QAM whilst avoiding sacrifice of distance or antenna sizes, by graceful step-down of modulation to lower rates during rare periods of high rainfall.

Use along with other bandwidth-enhancing technologies such as XPIC

1024QAM modulation is fully compatible with other methods to increase capacity such as XPIC (Cross Polar Interference Cancellation).  An advanced microwave modem featuring 1024QAM and XPIC can greatly increase capacity.  XPIC alone offers double the capacity compared to a single polarised non-XPIC solution.

1024QAM Microwave Summary

These latest advancements in advanced microwave modulation offer network operators an easy and inexpensive upgrade path to higher capacities to meet demand. Advanced modulation technology of 1024QAM is fully shipping and available today and offers a very cost-effective way to boost capacity in long-haul microwave applications.
