THE ENTERPRISE MARKET FROM WI-FI technology in China is expected to increase fourfold over the next three years, with a 45 percent annual growth rate for the market as a whole, according to a new white paper sponsored by the Wi-Fi Alliance.
When wireless sensors and detectors came on the market decades ago, the devices were known more for missing signals than capturing alarm activity. They were used in a “patch” type of approach, applied when hard-wired devices were impossible.
It is not a new cabling and wiring installation technique, but it has certainly come of age. Zone cabling is a little like the old multiplexed circuits of the early high-end burglar alarm systems (think New York jewelry stores) with a much more modern twist.
Combining technologies has allowed many systems to become part of the mainstream. One of the latest of these opportunities, is the conglomeration of power over Ethernet (PoE) with radio frequency identification (RFID).
Access control is a logical product to integrate. Technology continues to advance, especially in networked solutions, smart cards and biometrics, offering new capabilities and more application possibilities than ever before.
The debate Between wireless and wired networks continues, but the dialogue is changing. Though wireless has been an overly hyped technology, it is a significant service option to both consumers and businesses.
It has been predicted that the voice over Internet protocol (VoIP) market is in the early stages of dramatic growth, but VoIP needs a compelling reason for use if its proponents expect the technology to have a lasting effect. For the home, the major advantage appears to be reduced phone cost.
Some predict a totally wireless world, but that will probably never happen. There are so many other good media out there-including fiber optics, unshielded twisted pair, coaxial and other bundled wiring solutions-chances are there will always be room for both hardwired and wireless.
ZigBee-it sounds like a new toy or Disney character, but it is actually a technology that is helping to, once again, reshape wireless networking. ZigBee is a protocol known as the IEEE 802.15.4 Standard.
Just when those hungry for bandwidth thought they had struck gold with Wi-Fi, along comes something else to further the wireless revolution. WiMAX-Worldwide Interoperability for Microwave Access Forum-or WirelessMAN, is bound by the IEEE 802.16 standard.
Good old Bluetooth, the hot topic in regard to personal area networks (PANs). Though it goes into a sort of technology-remission every so often, it is still out there and has a loyal following. Attention is once again being focused in its direction, but this time for different reasons.
FOR SECURITY, COMMUNICATIONS, CONTROLS and other information technology functions, wireless is one of the fastest-emerging growth markets. In the business environment, wireless networking has to be safe and secure because sensitive data, personnel records and other information are at stake.
Yes, we've seen it before-at least the architecture. The Wireless Mesh Network looks a lot like the Public Switched Telephone Network (PSTN). Voice and data are converging and can be sent over wireless options.
‘Hotspots’ provide high return on investment In our connected world, seeing people frantically check their e-mail before boarding a plane has become commonplace. Instantaneous communications are par for the course, which is why public wireless LANs have come into their own.
Risks include hackers, jamming and more The popularity of wireless networking continues to grow for both businesses and individuals. Wireless networking allows people to obtain data and share information anywhere there is a wireless access point without being tethered to the wired network.
A quiet conversation in a noisy room The explosion of wireless applications in recent years has resulted in concern that the radio frequency (RF) spectrum is not broad enough to support future demands.
Wireless in 2004 and beyond is defined by innovative applications Wireless has gone beyond the realm of simple remote control. Now, wireless is always a part of the majority of the systems, services and products we use.
It’s an exciting year for ELECTRICAL CONTRACTOR magazine as we prepare to launch our survey for the next Contractor Profile. Two years ago, we published in-depth research that delivered some keen insight on how wireless technology and e-commerce were being embraced by the electrical contractor.
