Wireless Communications Questions and Answers
-
Antennas Brief tutorial
Antennas are simply lengths of conductive metal that radiate
radio signals into the air. Most common antennas are designed to
be one-quarter, sometimes one-half, the wavelength of the radio
signal they are to transmit/receive.
-
A two-way wireless system
is one in which the flow of information can go in two
directions. A transceiver at Point A can
send analog and discrete updates to Point B as well as receive
them from Point B. Likewise, a transceiver at Point B can both
send and receive updates.
-
Point-to-point transmission
involves only two wireless devices. Information travels between
Point A and Point B with no intermediary or other receiver.
-
One-way
wireless system
is one in which the flow of information can only go in one
direction. A transmitter at Point A can send analog and discrete
updates, but cannot receive any. Likewise, a receiver at Point B
can receive information, but cannot send any.
-
One-way signal duplication
is also referred to as point-to-multipoint transmission. Analog
and discrete updates are sent from Point A, any combination of
outputs can be received at Points B and C.
-
Frequency-hopping"
Frequency-hopping, spread spectrum (FHSS) radio is the method by which we
move our GENERALCOMMUNICAIONS.COM radio control signals from transmitter
to receiver. The other two types of radios available on the market today
are fixed frequency and direct sequence. Fixed-frequency radios require
a government-issued license in order to operate and have a fixed
bandwidth in which to send their signals.
-
Reliability of
Radio for Monitoring and Control in Industrial Environments
The Wireless radio technology has long been used in the form of fixed
frequency radio in our homes and cars and to transmit data in industrial
applications. Operation requires a government license that theoretically
prevents other broadcast signals inside the "bandwidth" and territory
covered by that license.

Antennas Tutorial: Antennas are simply lengths of
conductive metal that radiate radio signals into the air.
Most common antennas are designed to be one-quarter,
sometimes one-half, the wavelength of the radio signal they
are to transmit/receive. Wavelength is calculated with the
formula: Wavelength (meters) = 300/frequency (MHz).
Case Study:
The SPDC/AC unit was designed to be easily expanded:
power units can range from 2,000 Watts to 10,000 Watts. Its flexible platform
design allows it to be easily customized for use with area lighting, remote
communications, security systems, and surveillance equipment, to name a few
applications. Charge power alone can be doubled or tripled with the addition of
simple, cost-effective photovoltaic capture equipment.

Battery Backup Systems for LED Traffic Signs Increase
the public safety and reduced traffic congestion by allowing traffic lights to
function even during a power failure. A typical traffic signal intersection
experiences eight to ten local power outages annually. With IQUPS battery backup
power, some or all the traffic control signals can continue to operate. This
seamless switchover to battery power increases public safety and eliminates the
need to dispatch police or other service personnel to direct traffic. If all
traffic signals were converted to LEDs, the battery backup system would allow
full operation of the traffic signals during a power outage, thus alleviating
traffic congestion.
Important feature is the battery backup system’s ability to maintain the memory
of the traffic signal controller. The controller is responsible for sequencing
the on and off times of the various signals. With a battery backup system, the
controller’s memory can be maintained and return to normal operation once the
outage has ended. This feature has eliminated the time spent to reprogram
controllers after a power outage
Traffic IQUPS It is designed to provide backup power for critical LED traffic
light intersections. With 1,000 watts of true sinewave power available, IQFuel
Cell and maintenance free Deep cycle batteries.
Traffic IQUPS will drive most large LED systems. Its pure sinewave output is
cleaner than utility power, making it ideal for all loads.
Total distortion is typically less than 1.5%. Manufactured in the USA to the
highest standards possible, Traffic IQUPS system is the best choice for critical
load protection. power outage knocked out traffic lights, backup generators,

Depending on the consumers needs, the IQFuelCell automatically charges the
battery with up to 100 Ah per day. As independent power supply or in combination
with other systems, the IQFuelCell runs self-sufficiently for months.
The circuit is fully protected via breakers and fuses on the AC input,
connection to the batteries, and DC loads. Outdoor, lockable, aluminum enclosure
includes tamper-proof hardware suitable for pole or wall mounting. DC.

IQUPS, the generator assumes the full load in seven seconds. When utility power
is restored, the generator shuts off and signal operation is automatically
returned to the normal power source. "The IQUPS1800 will completely run the
intersection stoplights," said general manager for the DOT. "Other backup
systems will put the lights to flashing red. When the generator kicks in on the
IQUPS1800, the lights will fully function for 25 to 40 hours, depending on the
load at the intersection. When power is restored, the system returns to utility
power and the traffic signals do not need to be reset." Battery Backups Prevent
