Telecommunications
Telecommunications refer to the transmission of information over distances for the purpose of communication. In the modern age of electronics and electricity, telecommunication includes the use of electrical devices, radio and microwave communications, fiber optics, orbiting satellites and the Internet.

How do microwaves disperse during path loss between communication towers?
Because of the wave nature of electromagnetic waves, it's impossible to radiate
them from a 'launching structure' that has finite dimensions, and expect them
not to spread wider as they proceed over a great distance. So we must picture
any electromagnetic transmission ... whether it's light, radio, radar, microwave,
X-ray, etc. ... as a cone of energy as it proceeds from the transmitter, beginning
with a small cross-section as it leaves the launcher, and growing wider and wider
as it proceeds.
Realizing this, we now have a constant, fixed amount of power, propagating
across a surface area that gets bigger and bigger as we move farther and
farther from the source. So for a receiving antenna of any given size, it makes
sense that the farther the receiver is from the source, the less signal power
it's able to intercept, since that power is spread over a progressively larger
area as the distance increases.
People will also hasten to mention that there are many things all around in
the natural environment that absorb power from the signal, such as trees,
buildings, atmosphere, rain, clouds, soil, etc. They are correct, but these losses
are only a very small part of the weakening of microwave signals with distance.
By far the greatest factor is the geometric spreading with distance, described
above.
Naked DSL is a digital subscriber line that does not include analogue telephone service. The line does not have a dial tone for land line calling. The Naked DSL is a considered a standalone line or service.
Does a faster adsl router give faster download speed?
In most cases, ADSL speed is capped (fixed) by the ISP (Internet Service Provider).
So the would be no, it does NOT give faster download speed!
However, a faster ADSL router CAN improve speed on a local network (i.e. from laptop to desktop, transfers).
A BPO call center can help in centralizing your business operations and processes. A BPO services provider can be the hub for all processing activities which reduces the headache of having to deal with different service heads and employees. A BPO call center has one contact point for its client who will be project manager, who communicates and reports on a daily basis. Lesser the number of people to handle greater is the peace of mind. This will give ample time for a business to concentrate, develop and succeed in its field of expertise.
ISON Xperiences is the leading call center and BPO service provider in 14 countries of Afrcia covering South Africa, Nigeria, Kenya, Egypt with a strong focus in sub-saharan Africa having over 10,000 employees.
It's a convenient way to talk to people without having to see them personally.
How many 12v batteries could be use to power 500kva ups?
Well unless you mistyped something 500kva is 500,000 watts. That would be 41,666 12 volt batteries!

During the DESIGN PHASE of the SDLC or "System Development Life Cycle" is where a detailed plan for programmers to follow is developed.
What is the effect of frequency change on transmission losses?
Higher the frequency, higher the losses.
Who was the man who thought of dots and dashes to convey messages across telegraph wires?
Samuel Morse.
How laser improve telecommunication?
When a conversation occurs over a telephone system that uses optical fibers, the vibrations of your voice are converted to the pattern of the laser.
