C A S E S T U D Y Warehousing Unifying Wireless Across Remote Operations with Smarter 802.11n Opens a Sea of Productivity For Pacific Seafood, one of the nation’s most successful independently-owned seafood processing company supplying fresh fish to restaurants and stores across the U.S., wireless connectivity was hit or miss. And with the average person in the U.S. consuming approximately 16.8 lbs of seafood a year, any glitch in their production was not a welcome taste. Depending on the time of day, Wi-Fi connections could be strong and fast or weak or slow. The question was, why? With only a handful of IT staff, mostly located in its Clackamas, Oregon headquarters, to support a wide range of computer and networking responsibilities, Pacific Seafood needed better connectivity everywhere it operated. This included more than 30 processing plants, warehouses, distribution centers, fish farms, and sales offices spanning from Alaska to Texas. Founded in 1941, Pacific Seafood is a leading seafood company, operating state-of-the-art processing and distribution facilities throughout the Western United States. Pacific Seafood operates 30 remote sites and employs between 2,000 and 3,000 workers. Headquartered in Clackamas, Oregon, Pacific Seafood is one of the most successful vertically-integrated, independently-owned seafood company in North America. REQUIREMENTS Breakfast, Lunch, and Wi-Fi Operating in three shifts over 24-hours at its corporate headquarters, workers on break would head for a bank of microwave ovens, firing them up for lunches and snacks and in the process saturate the 2.4GHz spectrum, rendering the existing Wi-Fi network useless. For sales people in the building conducting millions of dollars in trades each day, this was simply unacceptable. OVERVIEW Pacific Seafood relies on Wi-Fi to support its entire business from plant processing to inventory management across vast operations. “We have a very diverse set of businesses, applications, users, and devices - all of which require robust wireless to maintain operational efficiency,” said Nathan Wiegand, network technician at Pacific Seafood. “We have created a Wi-Fi network over time with Teklogic, Cisco, Linksys, Proxim and Sonic Wall gear. But the system just didn’t cut it. We needed to address indoor interference issues, outdoor warehousing applications and long-range point-to-point and point-to-multipoint needs. And, we didn’t want to deploy a bunch of disparate products from different vendors and then have to act as a systems integrator to make it all work. With only 4 IT staff that just wasn’t an option.” Wiegand noted that the biggest problem, early on, was at the Pacific Seafood headquarters where they were seeing an increasing number of dropped connections, especially during certain times of the day. “We had to figure it out and fix it,” said Weigand. “It was really interfering with users’ work.” Adding to its Wi-Fi woes, poor coverage and unstable connectivity throughout its warehouse and processing plants, where workers on forklifts and pallet jacks track inventory using Motorola and Symbol MC9060 and MC9090 LEFT Frank Dulcich, president and CEO of Pacific Seafood, a leader in the worldwide seafood industry, took a more strategic view of Wi-Fi given the inherent mobility built into its business. • Centrally- and remotely-managed wireless system for 30+ remote sites • Complete coverage, high-performance at the lowest possible cost • Extended signal range with the smallest number of APs • Simplified administration and deployment • Stable connectivity • Interference avoidance • Ability to operate in extreme cold • Seamless integration with existing backend • Standard 802.3af PoE support • Multiple SSIDs • Simple guest networking SOLUTION • ZoneFlex 7962 dual-band indoor 802.11n Smart Wi-Fi APs • ZoneFlex 7762 dual-band outdoor 802.11n Smart Wi-FI APs • ZoneFlex 7731 point-to-point 802.11n Smart Wi-Fi bridge • ZoneDirector 1000 Smart WLAN controllers BENEFITS • 40% fewer APs, four-fold performance increase • Half the cost of Aruba/Cisco WLAN systems • Eliminated coverage holes and performance problems caused by interference • Entire enterprise-wide system managed and monitored at a single point • APs deployed with or without controller C A S E S T U D Y Warehousing “We take seafood all the way from the boat to the throat and rely on Wi-Fi throughout the entire production process. With such a diverse set of operations, users, applications and devices, wireless reliability was nonnegotiable. The Ruckus ZoneFlex was the only system we could find that combined unique RF layer advances with ease of use and flexible deployment options at a fraction of the cost of anything else.” Nathan Wiegand Wi-Fi-enabled handheld barcode scanners slowed business down as well. Workers use these devices to access the company’s inventory management system. Extremely latency-sensitive, Pacific Seafood’s inventory management system, HS4, is an essential application used to track fish and other inventory housed in large warehouses. Creating TELNET sessions between users and this application, if the system experiences delays, sessions are disconnected causing users to wait and establish new connections. Reliable wireless connectivity to this application wasn’t an option, it was a necessity. But given the harsh environmental conditions, obstructions and vast space, Pacific Seafood found it challenging to find a stable Wi-Fi solution. In several of its sites, Pacific Seafood had a number of buildings located several blocks apart. At its Westport site in southern Washington coast, for example, the company has a central plant with an office four blocks away in one direction. In the opposite direction of the plant, nearly a mile away, they have a loading dock where product is brought in. To reduce recurring monthly broadband costs to all of these buildings, Pacific Seafood was interested in highspeed 802.11n point-to-point/multipoint bridges to extend broadband connectivity to these sites. Pacific Seafood also needed extended coverage and more stable wireless connectivity to support dozens of computer “robot” units used to support the company’s in-house automated production control (APC) tracking system. Pacific Seafood’s APC tracks fish from dock to delivery with an integrated labeling and fish ticket function. The system isolates product and quickly provides Pacific Seafood specific information such as: on what boat the product arrived, where/when it was unloaded, when the product went into production, and where the product was shipped. Used on the loading docs, these four-wheeled, stainless framed carts are surrounded by a waterproofed box. Designed to operate in moist environments, each unit houses a PC, touch-screen display, barcode scanner, and printer used in the inventory tracking process. Specific Needs, Flexible Solutions While the company wanted more consistent Wi-Fi performance everywhere, the IT team needed Wi-Fi to be simple to deploy and easy to remotely manage. A tall order for a dispersed company that also needs a wireless system that has centralized management, support for a large number of concurrent users in a specific area, extended signal range and interference mitigation. In addition, Pacific Seafood wanted the flexibility to deploy APs in standalone mode at select sites with local controllers Network Technician Pacific Seafood RIGHT Results from an RF spectrum analysis show that the 2.4 GHz band was effectively saturated and unusable when workers fired up a bank of microwave ovens throughout the day. Dual-band 802.11n APs with interference mitigation and band steering solved this problem. 100% saturation of 2.4GHz RF spectrum, across all 802.11 C A S E S T U D Y Warehousing “When we installed the 802.11n pointto-point/multipoint bridges we saw an astounding increase, nearly 10x, and throughput to the point where users were coming to us saying ‘what happened?’ Today, these longrange point-to-point connections scream, performing and behaving just like a wired network but without recurring monthly DSL or fixed-line costs.” Nathan Wiegand Network Technician Pacific Seafood managing APs at other sites. Forcing all traffic through a single controller simply would not be cost-effective. “The wireless alternatives from Cisco, Aruba, and others could deliver coverage if you deployed a lot of APs, but were costly and complex to manage,” said Wiegand. “Even then, if we had gone with their proposals, they didn’t address some of the fundamental physical layer problems that were disrupting our Wi-Fi network.” Less is More After evaluating alternatives, Pacific Seafood standardized on the Ruckus ZoneFlex dual-band 802.11n system for both its indoor and outdoor applications. At its headquarters, Pacific Seafood deployed 40% fewer Ruckus APs than competitive suppliers suggested, and are realizing better coverage and more stable client connections. “Our warehouse staff has reported much better and stronger signal coverage, even with a fewer number of access points,” said Wiegand. Pacific Seafood has deployed the ZoneFlex dual-band 802.11n APs in its corporate offices and uses the integrated adaptive antenna technology and band steering to avoid interference. In its warehouse operations, Pacific Seafood has also deployed the outdoor dual-band 802.11n ZoneFlex 7762. This device integrates a heater so it can be used in extreme cold conditions such as in Pacific Seafood’s freezers. For long-range Wi-Fi extension, the ZoneFlex 7731 802.11n point-to-point/multipoint system is being used. “The point-to-point and multipoint bridges have been exceptional as far as throughput and ease of setup were concerned,” said Wiegand. “With our Proxim bridges we were seeing 5 to 10 Mbps. But with the ZoneFlex bridges we’ve seen an order of magnitude increase - they are literally as fast as a wire over nearly half a mile.” Enter Ruckus Wireless Each Ruckus ZoneFlex AP integrates a patented smart antenna array that focuses and directs Wi-Fi signals only where needed, continually steering signals around obstacles and interference that degrade performance. In addition, the product’s band-steering capabilities direct clients to less congested RF channels. “The combination of these features solves both the interference and high capacity problems we were seeing,” said Wiegand. “The real beauty of this is that it all happens automatically. We don’t have to worry about it or get involved.” IT administrators have the option to specify which APs broadcast which SSID to support the warehouse, office computers and guest services, with different parameters assigned for each virtual WLAN. Today, the IT staff uses the Ruckus FlexMaster system to perform wireless diagnostics at remote sites, gather stats, configure ZoneFlex APs and tap into ZoneDirector controllers. With a reliable wireless infrastructure now in place, they are exploring the possibility of using Wi-Fi to support voice or IP video cameras to troubleshoot plant problems in real-time. RIGHT Pacific Seafood operators 30 remote processing and distribution sites across the Pacific Northwest spanning from Alaska to Texas. “The combination of 802.11n and dynamic beamforming eliminates flaky coverage and reliability issues that have plagued Wi-Fi in the past. Ruckus Wireless is opening the door to an entirely new world of applications that, until now, just haven’t been possible,” said Wiegand.
