Google Highlights Challenges in Sharing Unlicensed Spectrum for LTE and Wi-Fi

FREMONT, CA: Google puts its observations on their blog where it elaborates the challenges in conducive co-existence of Long Term Evolution (LTE) and Wi-Fi in the unlicensed 5GHZ spectrum. The LTE technology reportedly has the tendency to crowd out the Wi-Fi implementations in this particular spectrum.

When compared with previous generations like 3G, deploying LTE networks enables the delivery of data traffic faster and more efficiently. Innovations are being made by the carriers in licensed spectrum in order to test its level of possibilities. By developing a spectrum policy that balances licensed and unlicensed opportunities, the platform has elevated the limits of the wireless economy, benefiting consumers, innovators, and investors.

“Although all players in the wireless ecosystem should have the ability to utilize unlicensed spectrum within the FCC’s rules, LTE over unlicensed has the potential to crowd out unlicensed services. Holders of licensed spectrum shouldn’t be able to convert the unlicensed 5 GHz band into a de-facto licensed spectrum band, and certainly they should not have the ability to drive out other unlicensed users,” points out Nihar Jindal, Google Hardware Engineer in his blog spot.

He also adds that a potential solution that would avoid coexistence problems in the 5 GHz band is for carriers instead to utilize newly available spectrum in the 3.5 GHz band for additional capacity. The Federal Communications Commission (FCC) recently identified the now-underutilized 3.5 GHz band spectrum as ideal for this kind of use.

By making the optimum use of all available spectrums one can develop workable coexistence and coordination mechanisms without hindering innovations of each other thereby encouraging a widespread access to unlicensed spectrum.
