Spectrum24® High-performance Wireless LAN Technology that transforms data into strategic advantage. Symbol's high-performance, wireless LAN bridges the workplace Portable terminals and laser scanners, laptop and fixed-mount computers...these tools capture and compute the information that drives operations, increases productivity, and creates competitive advantage. Imagine sending data-intensive files- sales information, transaction records, progress reports-quickly, accurately and wirelessly to your host computer. Then imagine your host computer dispatching instructions, updates, work orders and more, quickly, accurately and wirelessly back out to your workforce.
Spectrum24®, the high-performance, wireless LAN from Symbol Technologies, places information where it needs to be, in real time: on the retail or shop floor, in the warehouse or distribution hub, the manufacturing line or back room. With a commitment to open standards at every software and hardware interface, Spectrum24® is compatible with your current network technology, while ensuring seamless integration of future application tools. Plus, Spectrum24® supports the IEEE 802.11 standard for wireless LANs.
Spectrum24® is a strategic technology that empowers you to lead in industries as diverse as retail, transportation and logistics, healthcare, education, manufacturing, and many others. And it's from Symbol Technologies, global innovator in wireless LAN and data capture technology. Symbol understands how important your strategic vision is to the future of your enterprise in today's demanding business environment. All too often, however, what you see lies beyond the reach of ordinary information technology. Symbol's innovative products, industry systems expertise and global support overcome those boundaries... and transform your vision into a vision without boundaries.
Wherever there's data, Spectrum24® can transmit it in real time
Spectrum24® wireless LAN communications technology from Symbol Technologies keeps information and industries on the move. From factory floor to trading floor, Spectrum24® is the high-performance choice for data-intensive applications like these:
The Spectrum24® wireless LAN consists of hardware and software components that integrate seamlessly with wired environments. A complete solution, Spectrum24® includes access points, connectivity software, LAN adapters and management tools. One-piece PCMCIA and Industry Standard Architecture bus cards install in terminals, laptops, point-of-sale and other devices for quick, easy and seamless connection to the Spectrum24® wireless LAN.
Spectrum24®: High-performance, high-throughput wireless LAN technology for today and tomorrow
At one time, wireless LANs were largely proprietary. Today, however, users are moving rapidly to embrace open standards for all types of applications. Symbol's support of the IEEE 802.11 standard for wireless LANs "futureproofs" your wireless LAN investment and enables your organization to maximize, integrate and expand its technology investment: Diverse application tools and equipment can communicate over Symbol's high-performance wireless LAN, Spectrum24®.
A spectrum of benefits
Spectrum24® features ease of installation, seamless roaming, high throughput, expandable capacity and superior interference immunity. Symbol's commitment to open standards at every software and hardware interface makes Spectrum24® ideal for applications where mobile communications and real-time data access are essential:
Using frequency hopping spread spectrum cellular technology, Spectrum24® is designed to operate within the 2.4 to 2.5 GHz frequency range set aside by many governments for data communications in the U.S., Europe and Japan.
Communications architecture
Based on a simple bridge architecture, Spectrum24® provides transparent wireless connection to an Ethernet LAN through multiple access points. The full cellular network supports seamless, instantaneous roaming with load balancing. Remote stations communicate through either a one-piece PCMCIA adapter with attached antenna or through Industry Standard Architecture (ISA) bus cards. Each adapter is equipped with industry standard Network Driver Independent Specification (NDIS) and Open DataLink Interface (ODI) drivers, and access points are compatible with the Simple Network Management Protocol (SNMP).
Spectrum24®supports the IEEE 802.11 standard for wireless LANs, and supports both line-powered and battery-operated terminals. In Power Save Polling mode, the PCMCIA adapter draws less than 30 mA, maintaining full battery life of the host laptop or hand-held computer.
Integrates seamlessly
Spectrum24®'s commitment to open standards at every hardware and software interface allows seamless integration into existing wired networks. Just replace the NIC in a laptop, desktop or hand-held computer with Symbol's Wireless LAN PC Card or adapter and update the drivers. Mobile units communicate to high-throughput access points, providing a "wireless Ethernet" connection to your wired LAN. Plus, seamless roaming among network cells translates into virtually unlimited flexibility, making it easy to serve hard-to-wire locations and enables workstation relocation.
Advantages of frequency hopping
Frequency hopping is a modulation technique that offers a high-capacity network by using multiple access points within large or small environments. Each access point, which connects to the wired LAN backbone, executes a unique hopping pattern across 78 non-overlapping frequencies. The table of 66 hopping patterns specified in the IEEE 802.11 standard minimizes the probability that one cell operates on the same frequency at the same time as another cell. The result is access points operating at 2 Mbps without interruption-even when in close proximity to one another. Plus, access points can be added to expand capacity in the same geographic area as well as to extend range. Spectrum24®: More Features, More Benefits

The
wireless store-it's redefining retailing. With Spectrum24®,
scanning and portable computing go wherever required to capture data and
communicate it-allowing today's Just-In-Time, Quick Response and
Efficient Consumer Response philosophies to be implemented effectively.
Using wireless communications, today's leading retailers don't just
answer customer demand-they anticipate it. 
Transportation
companies needing flexibility, dependability and mobility for everything
from tracking shipments to capturing signatures will find that
Spectrum24® wireless communications provides the freedom and
the information to go wherever the goods go. Wireless communications
also supports the needs of weigh stations, loading docks, garages and
other remote locations. 
From
receiving to picking, packing and shipping, wireless communications is
revolutionizing the warehouse. It's dramatically increasing mobility,
accuracy, speed and overall productivity. Rugged, durable wireless
devices go to where tethered devices can't - to the point-of-activity.
With Spectrum24® paper-based systems are obsolete in an
environment where a PC calculates orders and downloads picking and
packing assignments in real time to warehouse personnel. 
In
manufacturing environments as diverse as a steel mill, auto assembly
plant and packaged goods processor, wireless communications via
Spectrum24® is tracking WIP and finished goods inventory,
forging a link between warehouse and assembly in JIT applications, and
providing links to higher level systems, including Manufacturing
Requirements Planning and Warehouse Management Systems. 
Performance
counts on Wall Street and on Wall Street they count on Spectrum24®
performance. The American Stock Exchange chose Spectrum24®
and Symbol hand-held terminals for real-time information exchange on the
trading floor and instant access to back office information. Spectrum24®'s
high throughput and interference immunity within crowded confines were
key, along with its ability to increase capacity. 
Spectrum24®
