Samsung Official Says LTE ProSe Available But Still in Early Stages
Tuesday, September 29, 2020 | Comments

A Samsung official said that LTE ProSe capabilities — the LTE equivalent of LMR direct mode — is available but still in its early stages.

“ProSe is at the early stages, and there has to be a lot of developments as we go along to handle off-net kind of solutions,” Samsung Senior Sales Manager Timothy Paul said during the International Wireless Communications Expo (IWCE) Virtual Event last month.

“LTE coverage is essential, and that is a challenge today, so off-net solutions are really critical, and ProSe needs a lot of iterations to get there,” Paul said.

Paul noted that the technology works now, but it has not been fully tested. The possible range of ProSe is currently very dependent on a user’s surroundings and what kind of buildings they are in or next to, Paul said.

Paul estimated that ProSe communications could reach up to a half mile right now but that range would be further limited by the type of environment a user is in and the power of the LTE devices.

“I would not say it’s ready,” Paul said. “It’s maybe half mile, but if you’re in a building, that gets significantly reduced. It’s not a high-power device, so those aspects need to be considered.”

Paul also noted that mission-critical push-to-talk (MCPTT) capabilities are available over Wi-Fi networks and for now that could be a better option for communications when main networks are down.

“Wi-Fi is kind of more universal, and MCPTT can run over Wi-Fi, and ProSe is an addition to it,” Paul said.

Vendors and public-safety officials, such as former Federal Emergency Management Administration (FEMA) Craig Fugate, have advocated using Wi-Fi to create mesh networks that can sustain emergency communications when networks are down.
