ZLO package

ZLO is a series of technical solutions to diminish the interference caused by other RF signals.

There is a need for secure, reliable and economic wireless communications. Wired technologies require costly and labor intensive infrastructure, and do not suit for retrofit practical environments. Wireless technologies are cost effective: there is no cabling and requires minimum labor. Current wireless technologies suffer from interference and security problems. Wireless equipment transfers information by sending RF signals. However, whenever two different devices send RF signals at the same frequency simultaneously, the two signals do compete in the air. These radio signals interfere with each other in the 315MHz or 433MHZ band where both operate. In most cases, the result is merely reduced data throughput that users might not even notice. Sometimes, though, the problem is worse. In some situations, it can even render the two signals completely inoperable. The worst scenario is when two implementations are "colocated." Then, they're so close that you have RF front-end saturation of the two radios' receivers. In essence, each radio receives such a strong input signal that it can't tease out the signal variations that represent the data. Interference between difference some RF devices, such as wireless fire alarms and infrared sensors, is not yet a common occurrence, fortunately, but the potential for widespread airwave squabbling is very real. Thus, HA system sending RF signals faced a dilemma – it is convenient to install and maintain, but under some special circumstance, its reliability maybe partly weakened by this flaw. Although adaptive hopping could, however, at least in theory, diminish some of the advantages of frequency hopping, the expensive cost prevents its usage in low date rate Home Automation systems. On the other hand, FCC approval for adaptive frequency hopping still has not occurred.

To avoid dueling radio waves and perhaps dueling users, Cuneatic developers worked hard to ensure harmony between every two RF signal senders. Among the many technical methods that they were considering, there was a main one, known as ZLO, that is likely to be widely accepted and applied to RF senders, the newer of other RF HA devices. The new mathematical solution appeared in Cuneatic chipsets and will likely lead to changes in other specification. Consumer products incorporating the new spec will probably start appearing in significant numbers.

As an excellent technical package, ZLO considered expandability while emphasizing solution of interruption. By using ZLO, RF senders have greatly diminished the interference caused by each other. For example, under the typical circumstance (ten signals sent by every sender/per day), ZLO reduce the interference rate between two senders to 1/1800 of their former standard.

ZLO make RF wireless systems increase the reliability while keeping their convenience.
