Entegrity wind systems was interested in a solution to provide remote real-time data acquisition and control to wind turbines across the country. Working in close partnership with Apterra Technologies, LLC a leading provider of software and systems for remote windfarm management, RfWeL developed various solutions to backhaul RTU data and allow remote access to turbines reliably and cost-effectively.

Menlo Park Fire Protection district was interested in replacing their aging T1's and create a high performance link between existing site and a newly acquired site. The cost of laying a new fiber optic link was prohibitive.

To obtain the high performance - high reliability, high full duplex throughput and high security we used unlicensed 60GHz radios which offered exceptional physical security (narrow beamwidth) and data security (AES encryption). For redundancy we used an OFDM-based high performance 5GHz PtP link and bonded the two links for failover & load-balancing using an industry-leading multiWAN router.

The City of Mesa in partnership with Arizona's Valley Metro needed to integrate a remote wireless communication system for a dynamic messaging system for the newly construction Main Street Bus Rapid Transport system.

System includes 3G WWAN systems for remote dynamic messaging system monitoring/control and Point-to-Point (PtP) links as alternative for copper/fiber for cross-link communication.

Gray Construction a leader in providing engineering, design and construction services to customers in the U.S. and around the world required a high performance PTZ camera to monitor construction sites before power and DSL/Cable/T1 drops were available. Due to the the large coverage zone we required a reliable and high datarate wireless radio link to backhaul live video for remote viewing in construction trailer and remotely at main office. We also required reliable 24x7 off-grid solar to power the system and backup batteries for 72hours of autonomy.

Rfwel's multidisciplinary teams were able to quickly come up with an effective solution that included correctly sizing solar grids per geography & loads and specifying sufficient battery capacity to address the high load demands of high performance Axis PTZ cameras. We also succesfully designed a near-line-of-sight (nLOS) unlicensed point-to-multipoint wireless radio link to backhaul the live video for offsite viewing and storage as well as to send power system status telemetry information.

For this project for EPA Region 9, Rfwel was tasked with outfitting Emergency Communication Trailers with mobile/nomadic wireless network for use inside the trailer and to provide a wireless hotspot to cover several hundred feet outside the trailer. We needed to utilize 3G/4G public carrier networks in such a way that we had reliable redundancy (since geography-specific signal coverage was not known apriori) as well as sufficient link-aggregation (load-balancing) to allow a good user experience for multiple concurrent users.

We used Peplink load-balancing routers, Cellular/WiMax 3G/4G modems, high gain Cellular/PCS/WiMax/LTE antennas, cellular RF bidirectional amplifiers and multiband diplexers to distribute multiple frequency band antennas using less cables and to same multiband modems.

A major oil drilling company needed a solution to remotely view activity in a remote oil rig. This system needed to be rugged to withstand the harsh environment in the rig, good quality and low cost to justify replication in other sites.

They required equipment that was to be used to send two video feeds from an oil drilling rig cabin to the clients office trailer approximately 300 feet apart. Each video feed was to supply the client with numerous views of equipment throughout the drilling rig. The original video was fed into the drilling cabin from eight cameras located throughout the rig which displayed via two monitors in the drilling cabin for the driller to view equipment they normally could not see from their view. Required equipment that could withstand the very rugged environment & potential RF interference from numerous other radios.

Statefarm the leading home and auto insurer in N. America was in need of a solution to improve the efficiency of its claim adjusters. They turned to Rfwel for a solution to outfit their fleet vehicles with mobile cellular routers and fixed cellular terminals which provided both data and voice connectivity while on the road. For agents in remote locations we added mobile cellular amplifiers and vehicle mount antennas to provide a reliable EVDO/HSDPA data connection at all times.

These systems provided Statefarm the ability to share a single cellular data connection between different incident responders which meant Statefarm could reduce their monthly data usage costs while providing a uniform usage experience across teams in diverse locations.

Up North Productions Inc. was interested to obtain an economical, reliable and high performance temporary WiFi hotspot and LAN network for their upcoming production. The WiFi hotspot was to cover various zones in the sprawling 5 acre fairground and campsite and to enable Internet connectivity of various ATM, Ticket Scanners, vendor booths & box offices at several venue entrances as well office equipment. The three day music and arts festival approximately was expected to attract five thousand attendees.

The two main challenges that RfWeL faced were how to economically & reliably backhaul the wireless network with enough speed for a good Internet experience and seamless gate & box office operations and how to cover such a large area with a reliable temporary setup with zero downtime and little management from the single on-site technician stationed at the event ...

East Valley Business Expo, a partnership of Chandler, Gilbert, Mesa & Tempe Arizona chamber of commerce was interested to setup a reliable complimentary WiFi hotspot for their annual expos. The temporary wireless network was to cover entire Mesa convention center and was to be free for attendees with authentication. From our success and learning in 2007's expo RfWeL made significant modifications to 2008's system.

Celebrity theatre one of Phoenix Arizonas most intriguing historing landmarks is a full-service 2,665 people capacity entertainment facility. They needed to provide a secure & isolated WiFi network at various entrances and regions within the facility to allow for portable hand-held ticket scanners. Since the scanners utilized an embedded 802.11a/b/g WLAN radio with no external antenna connections it was important to create a strong WiFi signal to reach the designated points where they needed to be used but without unduly interfering with other AP's & other WLAN's in the same 2.4GHz unlicensed band.

When the Radisson Poco Diablo Hotel in beautiful Sedona Arizona were in the process of renovating their 138 room hotel to include quality resort amenities they turned to RfWeL to provide self-controlled wireless thermostats and receivers to guarantee that guest comfort level was extremely pleasant. With careful equipment selection & RF sub-channel selection their chief engineer was able to economically and rapidly implement a feature that provides their Hotel a key differentiating amenity.

CPI Corp is the leading portrait studio operator in North America offering photography services in more than 3100 locations principally in Sears and Wal-Mart stores.

There was a need to separate the LAN Internet network of the portrait studios from that of the host retail establishment. Rfwel provided the cellular 3G WWAN routers to create a reliable isolated LAN network. In stores without a sufficiently strong or reliable cellular 3g signal we provided cellular bi-directional amplifiers/repeaters and high gain cellular band antennas.

A large privately held non-bank owned Mortgage Company approached us early one Friday afternoon to provide remote wireless Internet solutions to several new branches under construction in rural markets across the U.S. Many of these locations were well past their grand opening and for many the deadlines were rapidly approaching. T1 roll outs were in weeks to months! By monday afternoon RfWeL had enabled basic Internet in 5 locations and with a few tweaks had VPN and advanced networking features available end of day monday. By the end of week all locations within several miles of a cellular tower offering 3G data service were lit up. By the careful selection of cellular carrier, antenna, antenna orientation, amplifiers and enterprise-class multi-wan routers we were able to create a highly redundant, highly scaleable and high speed network that clearly wowed and eased the worry of edgy management.
