Knowing Wireless Transceiver Modules
Before the birth of wireless transceiver modules, a designer may choose to use RF integrated circuits (chips or chipsets). He can dictate how these chips will work in line with the software he will create. This could take months or even years of a cycle of rejection and reworking until the product passed is approved.
Wireless transceiver (transmitter/receiver) modules are a quicker time-to-market alternate to chip or chipsets that permit designers at all levels of RF experiece to add a comprehensive wireless system into their products. A lot of these transceiver modules are made as a drop-in solution where designers formulate a fitting pin-out on their processor board and provide serial data to the appropriate pins. There are also modules that provide the simplest integration which permit the designer to transmit raw UART information into the module and assume the same information out on the receiving end of the wireless network.
Since wireless transceiver modules are approved by FCC and other regulatory agencies, designers using FCC approved modules bypass further testing for their wireless products, allowing quickest time-to-market alternative. Pre-approved modules by ETSI and other regulatory bodies allow the designers to deploy their products around the world with minimal additional approvals. In this fast-paced world of wireless data, this makes transceiver modules a popular option for designers.
There are several fiber optic providers that offer a line of wireless transceiver modules that meet many of the performance and ease of use specifications of FCC. integrating these wireless data communicatioin solutions is as simple as transmitting data from a common port, communicating at a short or long range while consuming low power and maintaining high levels of interference rejection over numerous kinds of networks.
Wireless transceiver modules are made for varied purposes. One kind is a frequency-hopping spread spectrum transceiver module that uses a simple UART interface to communicate with the host system. Some utilize a proprietary filtering technology to provide interference immunity, including 70 dB of cell phone and pager rejection.
There are still different kinds of transceiver modules that support more port types and meet the standard industry requirements specified by FCC and other regulatory bodies. Along with the different kinds are different brands like Cisco XENPAK and HP SFP to suit your preference. The bottom line is wireless transceiver modules offer a reliable, robust wireless method to transmit serial data, whatever kind or brand of transceiver module it may be.
Need help with RF transmitter/receiver?
I need to build a simple, small, radio transmitter to transmit a constant signal. (for radio tracking applications) And also a receiver to pick up the signal and tell me the signal strength. I do not know much about this and was wondering if anyone has some advice or a website that could help me. Thanks!
The best thing is to use something like a baby monitor,because it has audio capability
or an automobile toy remote control
These can be found in thrifty stores near you and have the advantage of being legal!
You can't transmit just at any frequency! or any power level!
And it is too complex to explain why on this forum
What I suggest is that you find an audio source, something that produces a constant tone, like the beep in the microwave oven but continuous.
that you set-it up in a room and you walk around
you will receive the signal with your ears and it will be much easier to understand all the reflections phenomenon
The higher the pitch the easier to understand

Lenovo IdeaPad S2 7 with integrated WHDI mirroring hands-on (video) (Engadget Mobile)
With inconvenient HDMI cables and half-baked wireless solutions, HD streaming
from a tablet or laptop to an HDTV has been clunky, at best. And while WHDI
has improved the experience drastically by minimizing lag and providing a
standard platform, dongles went out of style long before the first slim tablet
made its debut several years ago. A near-perfect solution may be on the
horizon, however. Amimon has teamed up with Lenovo to integrate WHDI
technology in the new IdeaPad S2 7, enabling wireless streaming without the
need for an external transmitter -- you'll still need to attach a receiver to
your TV for now. We had a chance to go hands-on with the tablet and TV at the
company's suite at CES, and were quite impressed with how it performed.
Because all of the necessary hardware is integrated, there's not much to speak
of on that front, though it's worth noting that adding WHDI functionality
doesn't translate into a larger footprint. It's also very efficient, using "a
few hundred milliwatts" of power to mirror the tablet's display to an HDTV,
according to the company. There was no noticeable lag, and the picture
appeared very sharp ...
