It is well known that interference reduces cell phone coverage areas, network capacity and data rates available to the consumer. TensorComm's ICAT detects the sources of interference on the network, identifies the power of voice and data traffic channels for each source and estimates channel conditions, which in turn enables TensorComm to demonstrate ICT's ability to cancel interference and improve signal quality.
Recent analyses indicate that the most probable condition, occurring in more than half of all calls, consists of interference that ICT can identify and cancel over 90% of the time. In these conditions, ICT-enabled devices increase data throughput by up to 60%.
In addition, TensorComm announced the launch of its program to work cooperatively with wireless operators in analyzing and enhancing existing networks to improve service levels and spectral efficiency for end-users.
"As this activity illustrates, our momentum has never been greater," said John Thomas, TensorComm's founder and CEO. "We continue to add new capabilities to address the interference issues which are prevalent in wireless networks. Our engineering teams continue to innovate and implement receiver technologies for interference cancellation."
In a recent MIT Technology Review article, "Clearer Signals for Faster Phone Downloads", Sergio Verdu, professor of electrical engineering at Princeton University said, "CDMA signals interfere with each other because they are transmitted at the same time and at the same frequency." The article highlights the challenges posed by interference in networks based on code-division multiple access techniques to overcome interference produced as a result of the shared frequency. "It's similar to having a conversation in the midst of a noisy cocktail party," said John Thomas. "Pretty soon you notice that your friend has to speak a little louder as more people join in. Then you end up having to shout at each other in order to communicate. That's exactly what happens on CDMA and WCDMA networks."
Having recently announced its 75th patent filing in the area of interference cancellation, TensorComm continues to drive performance by assisting the wireless industry in providing consumers with higher data rates, while improving efficiency and lowering network costs. No other company offers the depth and breadth of technology that TensorComm has for this increasingly important area.
"Interference cancellation is the most advanced technology for improving data rates and voice quality in interference-limited wireless networks," said Dr. Louis Scharf, Chief Scientist of TensorComm, Inc. "Moreover, the technology applies to single- and multiple-antenna receivers, on the up- or down-link. It extends to LTE where MIMO and advanced transmitters force receivers to implement complex algorithms for demodulating and decoding high- rate transmissions."
TensorComm's technology will be embedded into the chips of mobile phones, significantly improving the performance of a network. Since wireless operators need not install any infrastructure to implement the solution, they benefit from this technology as each ICT-enabled mobile device is added to the network. The solution allows wireless operators to increase network efficiency for consumers who increasingly depend on reliable network connections for both voice and data.
