LongSpan 900-MHz Wireless Ethernet Tube Housing Kit
Other technologies, such as Wi-Fi
®
, don’t support the long-range distance
capability of the 900-MHz system. Wi-Fi delivers a large amount of data over short
distances and is great for real-time applications. Since it’s a broad-spectrum
technology that relies on a licensed band of wireless transmission, Wi-Fi is frequency
stagnant. Your grandparents or great-grandparents might have had a party-line
phone back in the 1930s. Similar to a party-line phone, Wi-Fi shares a broad-range
frequency spectrum between several users.
In contrast, the Long-Span 900-MHz Wireless Ethernet System operates over an
unlicensed wireless radio band. Several advantages for using the 900-MHz frequency
exist. First, this narrow-band frequency is ideal for low-speed, long-distance Ethernet
data transmission. Next, it’s thermally sustainable at high temperatures. And since it’s
a virtual Ethernet connection, you don’t have the hassle of installing a large wiring
infrastructure.
A LongSpan wireless Ethernet uplink runs at a speed of up to 1 Mbps. If you don’t
think that is fast enough for low-data rate applications, just consider that the uplink
speed on a typical DSL line is 38.4 kbps, well within the 1-Mbps limit for LongSpan.
The LongSpan system works in applications where the data rate requirement is
low. For example, it can be used in docking stations for a fleet of buses. At the
docking station, data can be transmitted to a media player in a digital signage
system. The data is stored in a buffer, then narrowcasted to digital screens on buses.
Other applications include providing links for an audio paging system at a golf
course, campground, campus, or mall.
The LongSpan system features:
• long-range reach (up to 40+ miles)
• robust operation
• industrial grade (operates at -40 to 160° F)
• easy installation
• fast enough speed (up to 1 Mbps)
• affordability (costs less than $2000)
