Wi-Fi and WiMAX are hot buzz words in wireless security technology. Integrators and dealers know the market is in love with mobile and remote access to security systems. For many, the way to provide that access is via Wi-Fi or WiMAX.
Thanks to its popularity in the consumer market, everyone who is technology-savvy knows the term Wi-Fi. Smart integrators and manufacturers are trumpeting their Wi-Fi credentials and promoting it as a way to monitor video systems or check at-home security settings from remote locations.
WiMAX (Worldwide Interoperability for Microwave Access) is another hot mobility protocol. It provides fixed and mobile Internet access. It is an IP-based, wireless broadband access technology that provides performance similar to 802.11/Wi-Fi networks with the coverage and QOS (quality of service) of cellular networks. A new, improved WiMAX-2 provides even higher speeds and better data rates.
"The key is higher data rates and ability to monitor the technology," said Dr. Mohammad Shakouri, vice president of the WiMAX Forum. "We will see a more integrated, distributed model for these technologies. Both inside buildings and outside the building we will see Wi-Fi, ZigBee, fiber and WiMAX integrated," he predicted. Consumers demand it.
WiFi and WiMAX hit their stride
When over 1,000 Americans were asked by Wakefield Research, Washington, D.C., what the best sign is that a new technology item is cutting edge, the two top answers (each with about 29 percent response) were: "It has Wi-Fi" and "It doesn't have wires." The survey, done in December 2010, showed how technology oriented Americans have become. More respondents said they check their e-mail before bed than kiss their spouse/significant others goodnight.
Security companies have sensed the public's affinity with Wi-Fi and wireless devices and many are hopping on board. The movers and shakers in the business all belong to the Wireless Ethernet Compatibility Alliance (WECA), a non-profit organization formed in 1999 to certify interoperability of Wi-Fi (IEEE 802.11) products and to promote Wi-Fi as the global wireless LAN standard across all market segments, including security.
As part of its role, WECA defined a test suite that defines how member products are tested to certify that they are interoperable with other vendor products. An independent test lab, The Silicon Valley Networking Lab, Inc. (www.svnl.com), conducts the testing. When a product successfully passes the test, the company will be granted the Wi-Fi seal of interoperability and may display the Wi-Fi logo on that product and its corresponding collateral material. Consumers are assured that any product bearing the Wi-Fi logo will work with other Wi-Fi products.
Many integrators are Cisco shops, so they are familiar with the basic wireless technology behind the Wi-Fi boom. It plays right into one of the hottest trends in security: allowing the customer to view video.
Wi-Fi will fill a niche in the video market, according to Vince Vittore, principal analyst with Yankee Group, Boston. "It makes perfect sense if you are a provider who wants to reach that fourth or fifth TV without having to drill through walls," he said. "Wi-Fi is a nice complement to what is out there."
"I know Verizon is using Z-Wave in their monitoring package that they launched at CES," Vittore said. He said that seemed to surprise some of the home networking companies he talked to at the show, especially the chip providers who did not expect a major US-based firm to use Z-Wave in a major offering.
Security remains a concern with Wi-Fi. About 17 percent of those responding to the Wakefield Research questions admitted that, in the past year they had tried to get on a Wi-Fi network that was not theirs—such as a neighbor's—in an attempt to save money.
