At AvaLAN Wireless, we have done our best to design our products in such a way as to push the limits of possibility, sometimes even venturing into the realms of the unfathomable. However, the Laws of Physics and the Universe still govern much of what we can and cannot do. We still have limits. The trick to making the most of our products is to know those limits. Knowing your limitations is not just beneficial to your project, it is crucial to its success. Knowing your limitations will save you time, money, effort, and especially frustration.
Wireless tube housing is a necessary component for keeping an eye on your remote installations, and also to keep your transmission secure. Such housings can use FHSS technology. FHSS means Frequency-hopping spread spectrum technology. As the name implies, while transmitting data, the systems hops frequency in a definite sequence which can be de-codified by the receiver to make a meaning of the data streamed. As per definition, FHSS is a method of transmitting a radio signal by rapidly switching the carrier wave in many frequency channels. The nature of switching is random, rather pseudorandom, and the sequence is known to the transmitter and the receiver (the system of coding and decoding is not that simple and there are lots of tricks). This saves the data from interference (from background noise) and eavesdropping (hacking). However, it is not a completely watertight security; an algorithm can discover the sequence and your armor get cracked and vulnerable, so for all sensitive installations another layer of security is deployed to eliminate the possibility of data jamming (a necessary evil of electronic war game). All such wireless tube housing gadgets are available in:
Point-to-Point (PTP) communication and Point-to-Multipoint (PTMP) communication may be lesser known terms to common users, but they hold great significance in the field of telecommunications. Two-way radio is a classic example of PTP communication. On the other hand, radio and television broadcasting are examples of PTMP communication. Both the communication systems have their distinct capabilities and a few limitations as well. The following section introduces you with the two and their applications.
What is wireless Ethernet? Wireless Ethernet is the use of unlicensed or licensed spectrum radios uniquely designed with Ethernet interfaces, for reliable industrial M2M Ethernet cable replacement.
Proprietary industrial wireless technologies offer a number of very compelling advantages over other standardized wireless technologies. If you ever wanted to have a more reliable Ethernet connection that could guarantee every single data packet getting through your network then proprietary networking could be your answer. Wireless standards are typically developed by multiple companies and suffer due to compromises that are made to accommodate all parties involved in the standards process. The right answer is to maintain your focus and create solutions that address your networking issues and concerns. Industrial wireless networks have very different requirements due to the robustness, reliability and continuous operation that is typically required. Through customization of over the air communications and through manipulations of Ethernet packet definitions, a proprietary solution can provide the exact solution your industrial network needs. This “top 10” list shows a number of the advantages proprietary wireless technologies has over more common standards based technologies.
Buying the right kind of wireless device requires an efficient knowledge of the frequencies they will be operated at. Now, the big question is – are 5.8 GHz radios better than 2.4 GHz and 900 MHz models. This would require a certain degree of information gathering before you make the final decision.
You can see Video Surveillance Systems at all places. Whether you are having lunch at a restaurant, doing shopping in a mall or entering your neighbor’s mansion, you are likely to witness a Video Surveillance Systems everywhere. Because of increasing thefts, attacks and other kinds of crimes, Video Surveillance Systems are installed at all public places, as well as in private houses, apartments and bungalows. For security purposes, Video Surveillance Systems have become very popular and extensively used. The technology used in making them is quite affordable, and thus they are economical. Read further to know the benefits of Video Surveillance Systems and the reasons for their extreme popularity.
When designing any system, engineers and system architects usually want to know how well the various components of the system will perform. In a microprocessor, logic or other digital system these questions usually are answered in terms of clock speeds, instructions per second or data throughput. With wireless communication, the most common performance questions involve range.
The Basics Of Spectrum Analyzer Science has always been about the observation of the existing phenomena and the discovery of new things from the same. Talking about the analysis and observation, one of the major scientific equipment meant for this purpose is the Spectrum Analyzer. The basic function of a Spectrum Analyzer is to measure the magnitude of input signals (both known & unknown). Though the input signal in a spectrum analyzer is generally electrical, other signals like - sound waves, light waves, etc. can also be measured. For this, however, a suitable transducer needs to be used along with the Spectrum Analyzer. The Spectrum Analyzer can be used to monitor the incoming signals on various parameters like dominant frequency, bandwidth, distortion, etc. Such analysis proves helpful in the characterization of Wireless Transmitters & other such electronic devices.
