Wireless network systems that support video, voice and data applications are becoming reliable and economical alternatives to their hardwired counterparts. Here is a sampling of the latest wireless network devices — and turnkey wireless systems — to hit the market.

Wireless Video Surveillance System

FOR BROADBAND WIRELESS NETWORKS

The system enables the delivery of IP video surveillance over wireless/WiFi mesh networks in a single product package. It integrates the supplier's Access/One Edge, Virtual/One, Priority/One and Manager/One hardware components and software platforms with Dotworkz's D2 vandal- and weatherproof enclosures to enable IP-ready pan/tilt/zoom (PTZ) cameras. Access/One Edge helps the system achieve continuous high throughput and low latency via the supplier's intelligent radio algorithms. Virtual/One and Priority/One provide packet prioritization and Quality of Service throughout the network for a reliable, uninterrupted stream of high-quality video. Manager/One manages the self-configuring network processes.

Wireless LAN Components

FOR SECURE, INDOOR/OUTDOOR MOBILE VOICE, VIDEO AND DATA APPLICATIONS

The WLAN (wireless local area network) product suite includes thin and thick mode access points, wireless LAN switches and a switch manager network administrator management system. WLAN switches support wireless Quality of Service and feature standards-based encryption, end-user authentication, advanced rogue detection/suppression and wireless intrusion prevention functions. The access points, available in five models, enable secure wireless mobility and support existing L2/L3 networking equipment. The switch manager allows network administrators to control configuration, permission and security options for the WLAN switch and access point infrastructure.

Wireless Ethernet Bridge

CREATES IP-COMPATIBLE NETWORKS FOR A VARIETY OF APPLICATIONS

The point-to-point wireless Ethernet bridge is designed for security, public safety and video surveillance applications. The wireless link creates an IP-compatible connection. The unit can operate on license-free 2.4-, 5.4-and 5.8-GHz frequency bands or on the public safety 4.9-GHz band. Users can select their preferred frequency via a Web-based interface during installation. The interface also allows users to align and monitor the wireless link. System features include an integrated planar antenna, a proprietary Power-over-Ethernet injector and a sleek design for discreet deployments in urban areas.

Wireless Mesh Nodes

SUPPORT TWO RADIO MODES TO SUIT APPLICATION

The mesh nodes provide reliable Ethernet connectivity over a self-forming wireless mesh backbone for indoor, outdoor and moving vehicle applications. They feature multiple Ethernet ports for connecting network devices and other networks to the mesh configuration. The nodes provide up to 70 Mbps throughput and operate at 2.4 GHz, 4.9 GHz (U.S. public safety licensed band) or 5 GHz. They are equipped with either single or dual radios operating at 400 mW. Two radio modes, bonded and linear, are supported. HotPort 6000 Wireless Mesh Nodes, Firetide Inc. (firetide.com) Circle No. 4 or visit securitysolutions.com/productinfo.

Point-to-Multipoint Wireless Transceiver

PROVIDES LONG-RANGE WIRELESS TRANSMISSION FOR IP ACCESS CONTROL SYSTEMS

The non-line-of-site wireless Ethernet system includes a 900-MHz point-to-multipoint, 1.54-Mbps Ethernet radio transceiver. The unit is capable of transmitting 128-bit Ethernet access control authorization requests through 10 typical building walls and four floors, or through a grove of trees outdoors at a distance of 1,500 ft. Up to 12 subscriber units can be mated to the 900-MHz unit. The supplier also offers the 900-MHz transceiver and a 5.8-GHz line-of-sight transceiver (AV5800) in module form. The FCC-certified modules are flexible, simple to operate and require only 1.25 watts of power in full-transit mode.

Wireless Ethernet Point-to-Point System

SUPPORTS IP CAMERAS, DVRS, ENCODERS, DECODERS AND WEB SERVERS

The dual-band wireless transmission system operates on a license-free 5.8-GHz band. It consists of dual 802.11a RF modules that transmit bi-directional data at 20 Mbps in standard mode and 50 Mbps in super mode. The system enables a variety of IP cameras, DVRs, encoders, decoders and Web servers to be used across wireless line-of-site links at ranges of 2,500 ft. to 30 miles. It is designed as a plug-and-play Ethernet/Cat-5 cable replacement device. Simple installation requires users to mount the RF modules, point them at each other and connect the power and Ethernet/Cat-5 cables. MiniLink Wireless Ethernet system, MicroTek Electronics Inc.
