Pseudo random Polarization Hopping ( PPH )
A novel narrowband modulation offering low probability of exploitation ( LPE, a measure of information security ) and anti jamming for high data rate transmissions. Unlike the conventional LPE and AJ modulation such as direct sequence spread spectrum or frequency hopping which occupy a very wide spectrum, PPH does the hopping in polarization domain, thus occupying a very narrow spectrum. This feature makes PPH the only choice for high data transmissions with LPE and AJ security feature over bandwidth constrained channels.

Polarized MIMO antennas
As the order of MIMO systems go beyond 2 in 2 out, co-location of the antennas become difficult due to the minimal spatial requirement for uncorrelated channels. This difficulty has been avoided by separating the antennas in Polarization domain. Polarizone has identified and generated the different states of Polarizations for 3 in 3 out, 4 in 4 out and other higher order MIMO systems.

4 in 4 out MIMO
This is the first time a fully integrated 4 in 4 out MIMO system was introduced in the market. This system has enormous computational capability and can offer MIMO implementation of WiFi, WiMAX and many other standards based or proprietary communication protocols
