Ceragon's Q1 Revenues Below Expectations

Citing delayed sales, Ceragon announced that its Q1 revenues will be in the range of $89 million to $91 million, below the company's guidance of $95 million to $105 million. GAAP EPS is now expected to be in the range of $(0.36) to $(0.39). EPS on a non-GAAP basis is expected to be in the range of $(0.15) to $(0.18).

"Our revenues will not reach the low end of our guidance for the first quarter of 2013 because it is taking longer than we expected to close certain deals," said Ira Palti, President and CEO of Ceragon: "We experienced a level of bookings in Q1 lower than we would have expected based on seasonal weakness, reflecting operators' cautious approach, despite the need for additional capacity.

"We expect the re-evaluation of some aspects of customers' business models, as well as continued intense budget scrutiny, to cause longer sales cycles to persist, even though Q2 bookings are likely to show some improvement for seasonal reasons. We will provide more color during our regularly scheduled quarterly call on May 6th."

DragonWave Debuts Compact, Sub-6 GHz Microwave Radio

DragonWave unveiled an all-outdoor, sub-6 GHz microwave radio for rural deployments, government and private networks, vertical industries, mobile and extended network backhaul.

The DragonWave Harmony Radio Lite offers a form factor of only 7.5 in square including integrated antenna.  Its point-to-point microwave radio supports both licensed and unlicensed spectrum and is ideally suited for non-line-of-sight (NLOS) scenarios. It includes standard Ethernet interfaces. Streamlined functionality is further complimented by low power consumption (under 15W), PoE compatibility, reduced cabling requirements and low delay. Synchronization through 1588v2 and SynchE eliminates the need for an external synchronization source.

Harmony Radio Lite links can be deployed using a tree topology, with macrocell traffic aggregation points on rooftops, or with tail, chain or small hub microsites at street level, which reduces interference and offers more flexible network connectivity, as well as simplifying network expansion and helping to ensure protected network architectures.

"Addressing vertical markets and a growing demand for rural and suburban backhaul has driven our product strategy with the introduction of the Harmony Radio Lite,” said Peter Allen, CEO. “The value proposition customers seek is Quality of Service assurance, affordability and ease of deployment and management of the network ­– we’re confident the Harmony Radio Lite raises the bar by bringing the lowest cost per bit with uncompromised performance."

Dell'Oro: Microwave Transmission Market Declined 12% in 2012

The point-to-point Microwave Transmission equipment market declined 12 percent worldwide in 2012 to $4.2 billion as radio transceiver shipments declined 6 percent to 1.5 million, according to a new report from Dell'Oro Group.

"The market for microwave backhaul was truly impacted by surprisingly low demand in the European region," said Jimmy Yu, Vice President of Microwave Transmission research at Dell'Oro Group.  "Although the market really took a step back this year, there were a couple of bright spots.  The first was the growth in sales in the North American region as operators expanded their Long Term Evolution (LTE) networks.  The second was the greater usage of ultra-high-capacity links using E-band frequencies to deliver a full gigabit of backhaul capacity to cell towers," Yu added.

Some highlights:

  • The North American region was the only region to achieve significant positive growth in 2012, growing 13 percent.  Alcatel-Lucent captured the majority of the North American market, garnering 44 percent market share.
  • Microwave sales in the European region pulled back sharply in 2012, declining 28 percent.  Ericsson held the highest share of the European market at 32 percent.
  • Ultra-high-capacity radio transceiver shipments grew nearly 60 percent in 2012.

Infonetics: Microwave Radio Market Declines

The global microwave equipment market totaled $1.2 billion in 4Q12, down 3% from 3Q12, and down 12% from the year-ago 4th quarter (4Q11), according to a new report from Infonetics Research.  Microwave equipment spending declined 10% worldwide for the full year 2012.

"The microwave equipment market ended 2012 tamely,” reports Richard Webb, directing analyst for microwave and carrier WiFi at Infonetics Research. “The expected year-end boost to quarterly revenues did not materialize, as price erosion and capex conservation combined to deliver a seasonally countertrend 4th quarter dip. We expect the market trough to hang around a little while longer before renewed growth begins in late 2013,” Webb continues. “And by 2017, Infonetics forecasts the microwave equipment market to reach $5.2 billion, powered by the continuing demand for backhaul capacity at macrocell sites."

Some other notes:

  • Ericsson, Huawei, and NEC held steady at the top of the microwave equipment revenue leaderboard in 4Q12, though #4 Alcatel-Lucent closed the gap on NEC significantly, pulling to within a hair’s breadth
  • Aviat Networks leapfrogged Ceragon to move into the #5 spot in 4Q12, cracking the top 5 for the 1st time
  • Alcatel-Lucent continues to lead the all-packet segment, accounting for half of all revenue.

Tarana's Wireless Backhaul Cleans Signals with Advanced DSPs

Tarana Wireless, a start-up based in Santa Clara, California, is showcasing its new "AbsoluteAir" wireless backhaul solution for supporting small cell deployments in both non–line of sight (NLoS) and line–of–sight (LoS) operation.

Tarana features a unique Concentrating Multipoint (CMP) architecture that delivers a full 75 Mbps backhaul capacity to each small cell and enables the number of links to scale as data demand grows, without degrading per–link capacity.  The AbsoluteAir product line consists of Concentrator Nodes (CNs), End Nodes (ENs), and an Element Management System (EMS). Each EN connects directly via Ethernet to a small cell providing it with a full 75 Mbps dedicated backhaul capacity. The CN aggregates links for up to four ENs providing 300 Mbps capacity in a single 10 MHz channel – delivering spectral efficiency of 30 bits per second per hertz. A CN may be co–located with a macro cell where direct access to high capacity connectivity to the carrier’s core network is readily available. By leveraging existing carrier sites for CN installations, significant ongoing operating cost benefits are realized.

Tarana leverages advanced signal processing algorithms to optimize link performance. The company says it is able to deliver the full data rate on every link even in dense small cell deployments at a range of 2–4km in NLoS, and practically unconstrained in LoS operation.

Each link utilizes the same 10 MHz channel while maintaining full link capacity. The company is supporting licensed and lightly licensed TDD bands from 2.5–3.7 GHz,

Tarana's AbsoluteAir antenna has a 100° aperture that dynamically aligns, eliminating time–consuming alignment during both setup and ongoing operation. The company says this enables deployment of individual nodes in just 15 minutes.

“AbsoluteAir was designed to meet requests from global carriers for a cost effective backhaul solution that could be easily and quickly deployed anywhere and everywhere across a metro area, without compromising on performance or scalability. I am happy to report that recent urban network tests confirm that our target specifications have been achieved” said Sergiu Nedevschi, executive vice president, chief product officer, and co–founder, Tarana Wireless.

Ceragon Says Mobile Operators Showing Extreme Caution in Spending

Ceragon Networks reported Q3 revenue of $118.0 million, up 2% from $116.1 million for the third quarter of 2011, and down 1% from $119.1 million in the second quarter of 2012.  Net loss (GAAP) was $(2.7) million or $(0.07) per basic share and diluted share, compared to net loss of $(6.7) million in the third quarter of 2011, or$(0.19) per basic share and diluted share.

"We are pleased to achieve a gross margin near our target and reach an operating profit margin of 4%," said Ira Palti, President and CEO of Ceragon. "We are making excellent progress toward our profitability goal. We remain optimistic about the business because we are well-positioned in an attractive sector that is likely to enjoy numerous growth drivers for years to come, but we are not immune to macroeconomic factors that are causing the second half of the year to be slower than originally expected.  After a dramatic pickup in bookings to record levels in Q2, we experienced a reversal in the order pattern in Q3. Although a portion of this change is accounted for by some large orders being delayed until Q4, due to the macroeconomic environment, we expect Q4 revenues to decline sequentially. With operators showing extreme caution regarding spending, sales cycles are lengthening and we are assuming no improvement from Q4 levels as we move into 2013."

DragonWave Cranks up Packet Microwave to 1.3 Gbps with 2048 QAM

DragonWave confirmed the functionality of higher modulation modes of up to 2048 QAM on its Horizon packet microwave products. 

In field tests conducted in Odessa, Ukraine, DragonWave's in-country partner UKRCOM and their customer, Intertelecom, demonstrated the radios’ ability to transport up to 37 percent more data through existing microwave channels. This testing was combined with dual channel operation and DragonWave’s unique Bandwidth Accelerator feature. 

DragonWave said the combination of these two features and the higher 2048 QAM modulation, offered an increase in capacity of greater than three times to more than 1.3 Gbps. This improves spectral efficiency and, correspondingly, lowers the operator’s cost per bit. 

DragonWave  noted that it has shipped over 800 Horizon links to Intertelecom through its local integration partner, UKRCOM to date.

“We explored other options for increasing link capacity such as XPIC, but we soon realized that DragonWave’s solution of coupling higher modulation modes with Hitless Automatic Adaptive Modulation allows us to meet the growing backhaul demands without needing to re-engineer existing links or purchase additional radios,” said Boris Akulov, CEO at Intertelecom.  “In effect, we have found a very cost efficient and streamlined means to triple our network capacity.”

“The successful field testing of 2048 QAM marks another milestone in DragonWave being first to market with technology and innovation that sets us apart from the competition,” said DragonWave CEO Peter Allen. “We congratulate our Ukrainian customers on their performance results and are encouraged to be expanding our market share in an important and growing region for microwave transport.”
