Ruckus ZoneFlex 7762 Wireless Access Point Teardown

17 May 2012
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

IHS Insight Perspective

As data traffic on wireless access networks continues to grow at exponential rates, carriers are looking to public Wi-Fi hotspots to offload data traffic from their cellular networks. The Wi-Fi access point from Ruckus is deisgned to be a ruggedized device that can exists in harsh external environment and supports high data rates with 802.11n 3x3 MIMO implenetations.

Ruckus is a US based tier one vendor in the enterprise and carrier grade Wi-Fi access market. We define the top tier players in the space as Cisco, Motorola, Aruba Networks and Ruckus Wireless and collectively represent roughly 80% of this market.'

Overall Significance

The Ruckus ZoneFlex 7762 is an enterprise grade mesh supported outdoor concurrent dual-band (2.4/5GHz) 802.11n 3x3 MIMO wireless access point. According to the company, the device is capable to achieve '150-200Mbps (300Mbps bursts) sustainable throughput for a 5000 sq. foot area for each radio' with up to 20 concurrent voice calls, 100 simultaneous data users or 600Mbps capacity per access point. This device is also equipped with 2 auto MDX, auto sensing 10/100/1000 Mbps RJ-45 ports with 802.3at PoE (Power over Ethernet) compliant input and 802.3af PoE compliant output.

Feature Significance

This device is embedded with a so-called Beamflex smart antenna. According to the company, 'BeamFlex is MIMO smart antenna technology ... it combines a compact internal antenna array with expert system control software...constantly reconfiguring itself in real-time as interference is encountered... steers RF signals around interference to eliminate Wi-Fi dead spots while increasing the range and performance of the Wi-Fi network.'

Volume Estimations

10,000 Annual # of Units
2 Total Years

For the purposes of this teardown analysis, we have assumed an Annual Production Volume of 10000 units and a Product Lifetime Volume of 2 year(s).

Teardown volume and production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

Market Performance

Per IHS's IMS Research forecast, 802.11n will remain the dominant technology in 2012 to 2016. Despite shipments of 802.11n increasing over the forecast period, the overall market share of 802.11n is predicted to be eroded by the launch of 802.11ac in 2012.

Cost Notes

At the kind of volumes Ruckus is building at (10K units per year for two years), and given their 'niche' that is relatively low volume, they are probably either a) working through distributors (such as Avnet and Arrow), or b) working directly with some OEMs that are 'price protecting' their distribution partners (charging a price that makes it of equal interest for the client to actually use the distributors). Our analysis accounts for low volumes in pricing, however, keep in mind that in low volumes, pricing disparities from one customer to the next, for the same parts, can be huge, and make the job of estimating such purchases prices much harder,

Not Included in Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

As with most electronic hardware, this equipment may be built for Ruckus by an outside contract manufacturer, but may also be built in-house, as is often the case for OEM/ODM type companies which are common in Taiwan. For the purposes of our analysis, our cost structures in manufacturing represent the cost to the manufacturer, without markup. If an EMS is involved, one would have to add a fair margin for the EMS provider, on top of our cost assessment, in order to provide a 'fair price' to the manufacturer. EMS providers often operate in the low single digits on margins, but tend to make up for such low margins when working with low volume products such as this.

Country of Origin

For the purposes of this analysis, we are assuming the following country(ies) of origin for each level of assembly, based on a combination of 'Made In' markings, and/or assumptions based on our knowledge of such equipment.

Antenna Assembly - Taiwan
Box Contents - Taiwan
Main PCB - Taiwan
Other - Enclosures / Final Assembly - Taiwan
PoE Injector Module - Taiwan

Labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ?Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design Complexity

Component counts by assembly and the number of assembly are indicators of design complexity and efficeincy.

Component Qty: 1342 - Main PCB
Component Qty: 65 - Other - Enclosures / Final Assembly
Component Qty: 76 - Box Contents
Component Qty: 471 - Antenna Assembly
Component Qty: 27 - PoE Injector Module
Component Qty: 1981 - Grand Total

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.

Design Notes

At its core - the Ruckus ZoneFlex 7762 access point is essentially two sets of Qualcomm Atheros Baseband (AR9160) + RF IC (AR9103 & AR9106, respectively for 2.4 & 5GHz band) tied together by a core processor. The processor is a Qualcomm Atheros (AR7161-BC1A) - Wireless Network Processor - 32-Bit MIPS 24K Processor Core, 680MHz, Dual Gigabit Ethernet MACs, Dual USB 2.0 MAC/PHY, DDR & SPI Serial Flash Interface.

This chip represents the bulk of functionality of the device and requires little else to perform its functions, though the device does also have an Altera (EPM240M100I5N) Complex Programmable Logic Device, which is probably added for the smart antenna functionality, along with a number of discrete I/O components such as 2 Marvell (88E1118-NNC1) ethernet transceivers, and a ST Microelectronics (LIS302DL) MEMS accelerometer.

This device also features 2 Nanya DDR SDRAM (256Mb each) and Micron serial NOR Flash (128Mb).
