Coexistence of different technologies using the same frequencies is an important part of implementing a healthy ecosystem in spectrum sharing. This paper shows Ofinno’s commitment to quality and detailed technical analysis on complex technological issues.

Ofinno Technologies, LLC, a wireless communications research company, announced today their research into whether Wi-Fi and LTE-Unlicensed can peacefully coexist.
LTE networks are currently overburdened with data. More spectrum is needed to offload part of the data traffic. One approach involves the use of unlicensed spectrum alongside licensed bands.
3GPP and other industry alliances have been considering the possibility of extending LTE into the unlicensed spectrum in an effort to stem LTE data traffic. When compared to data offload using Wi-Fi, this approach has the advantage of seamless integration into the existing LTE evolved packet core (EPC) architecture.
There has been a lot of dispute in the telecommunications industry as to whether Wi-Fi and LTE-Unlicensed can coexist without negative ramifications. Ofinno’s research aims to find out how Wi-Fi performs in the presence of duty cycle based LTE-U transmission on the same channel.
“A simple static airtime sharing between unlicensed LTE and Wi-Fi is generally not sufficient to ensure fair coexistence between these systems,” said Alireza Babaei, Senior Technical Staff at Ofinno Technologies, LLC. “However, other mechanisms that have been incorporated in the 3GPP version of unlicensed LTE, such as listen-before-talk, are well studied and enhance coexistence performance. Alternatively, adaptive airtime sharing where the duty cycle of LTE transmission dynamically changes considering Wi-Fi traffic, improves the coexistence performance.”
Ofinno’s research paper details how Wi-Fi and LTE-U coexist under a variety of circumstances. Depending on the interference noise ratio (INR), Ofinno classifies LTE-U interference as strong or weak and mathematical models are established accordingly.
“Coexistence of different technologies using the same frequencies is an important part of implementing a healthy ecosystem in spectrum sharing,” added Esmael Dinan, CEO of Ofinno Technologies, LLC. “This paper shows Ofinno’s commitment to quality and detailed technical analysis on complex technological issues facing the industry today.”
In the paper, the average throughput and service of Wi-Fi are formulated as functions of Wi-Fi and LTE-U system parameters are determined using probability theory. The Monte Carlo analysis is used to demonstrate the frames of Wi-Fi and LTE-U airtime sharing.
In order to overcome observed unfairness, Ofinno’s research discovered that other technologies must be developed for LTE networks. Ofinno’s full analysis and conclusions can be viewed at http://www.ofinno.com.
