WaveRider Communications, the leader in non-line-of-sight wireless broadband technology and deployments, today announced that North West Net, an Internet service provider in Ohio, has deployed WaveRider’s 900 MHz systems to establish mobile broadband communications for police and other emergency personnel in the city of Van Wert, Ohio. When fully deployed, the system will support voice, video and data communications for police and other emergency workers in the field.
The wireless broadband connections are established via the MMT9000 mobile terminal, a part of WaveRider’s MobileWan network offering. Voice, video and data communications are transmitted to MMT9000s installed in police cars via multiple base stations located throughout the city.
The mobilized MMT9000 features:
- Over-the-air data rates of 2.75 Mbps and access speeds of 2 Mbps
- Supports voice, video and data communications
- Enables end-user mobility; suitable for in-vehicle installations
- Extended temperature range of -40 C to 50 C
- Superior 900MHz non-line-of-sight performance
- Compatible with WaveRider s LMS4000 900MHz systems
- Certified with WaveRider vehicle antenna 302-9000, various vehicle mounts available
North West Net also plans to expand its bright.net broadband wireless services to businesses and residents with WaveRider’s 900 MHz non-line-of-sight wireless systems. Connections will be established via end-user modems that can be easily installed indoors by the subscriber, or outdoors by bright.net.
Another municipality using the 900 Mhz band is SandyNet, in Sandy, Oregon. The Oregonian has a story on the city-run wireless alternative introduced a couple of years ago by the city of Sandy, Oregon (pop 5,385).
The $29.95 monthly fee requires a six-month commitment. Customers who choose to buy the modem and related equipment themselves rather than lease the city’s can get wireless service for $19.95 a month.
About 160 Sandy households or businesses have signed up for wireless service.
The city’s network administrator, Scott Brown, also runs Timberline Networks and helped install a new computer system in the school district.
Scott Brown, at Portland’s PersonalTelco meeting last month, explained how Waverider’s 900 Mhz system was able to penetrate foliage and deliver wireless services to his community. He lusted after Motorola’s 900 Mhz Canopy system with 6 sector nodes. Currently too pricey to pencil out.
The 900 Mhz band is often used to send telemetry and monitor operations because it often has better range. Synetcom SCADA Radios and OK Solar, for example, have wireless solutions such as solar powered cameras.
SCADA (Supervisory Control and Data Acquisition) radios are used in industrial and engineering applications. They monitor and control remote utilities from a master location.
SCADA wireless solutions can be spotted by their tell-tale yagi antennas and are often used in electric generation and distribution, oil and gas metering and control, traffic signals, water management, pump systems and mass transit.
As Wikipedia explains, an important part of SCADA are simple alarms. Emails and text messages are often sent along with an alarm activation allerting managers along with the SCADA operator.
MaxStream has a long range 900 MHz wireless bridge. The XPress Ethernet Bridge allows host and client Ethernet connections to communicate at a range of up to 15 miles (line-of-sight with high gain antennas) at speeds up to 1.5 Mbps in the unlicensed 900 MHz ISM band.
Maxstream recently introduced their XBee product family which provides ZigBee/802.15.4 modules that feature low power, low-cost solutions for integrating the ZigBee standard.
XBee OEM modules (right) operate in the 2.4 GHz frequency and have an output power of either 1 mW or 100 mW. The 100 mW XBee-PRO, for example, is said to perform up to 4000 (1200 m).
Other 900 Mhz gear includes AvaLAN s 900 MHz Ethernet bridges. Their 900MHz wireless kit includes: two (2) radios, two (2) power supplies, two (2) 2.5dBi antennas starting at $699 (indoor) and $999 (outdoor). Trango s 900 MHz client delivers multi-point, large-scale, residential and commercial wireless broadband access.
Airspan’s 700 MHz equipment requires a license but has an even longer NOS range. Vyyo’s Non-Line-of-Sight 700 Mhz modem, the V284 provides coverage inside homes more than three miles from the base station and more than 9 miles NLOS outdoors.
