Best Police Scanner for Louisiana: Frequencies, Systems & Recommendations

A buyer's guide to LWIN, parish encryption, and the right scanner for where you live

Most of Louisiana listens on one statewide digital radio system. The biggest parishes in the state do not. That split matters more here than in most places, because it decides whether the scanner you buy needs to track one system or come ready to switch between two or three depending on where you are standing. Add in hurricane season, when mutual aid traffic surges across parish lines, and Louisiana rewards a bit of homework before you buy.

Louisiana's Statewide System: LWIN

The backbone of Louisiana public safety radio is LWIN, the Louisiana Wireless Information Network. It is an IP networked, P25 compliant trunked system running on 700 and 800 MHz, built and maintained through the Governor's Office of Homeland Security and Emergency Preparedness. Louisiana State Police troopers, most parish sheriff's offices, and a large share of fire and EMS agencies carry their dispatch and tactical traffic over LWIN talkgroups.

LWIN was originally rolled out under the name LATIE before the state renamed it, so you may still see the old name in older forum threads. During hurricanes and other large scale incidents, LWIN also carries the statewide mutual aid and interoperability talkgroups that let agencies from different parishes coordinate, which is part of why it is worth having programmed even outside your home parish.

Where Louisiana Breaks From the Pattern

Two parts of the state do not run on standard LWIN for local law enforcement. Caddo Parish, home to Shreveport, operates its own independent P25 Phase II trunked system with dedicated control channels in the 851 to 853 MHz range, separate from the statewide network.

The New Orleans metro area is its own case as well. Orleans, Jefferson, St. Bernard, and Plaquemines parishes share a simulcast system built from the former Jefferson Parish Sheriff's 800 MHz network combined with LSP's LWIN infrastructure, run under the Region 1 Urban Area Security Initiative. Several transmitter sites broadcast together so the system behaves like one wide coverage area, which is exactly the kind of setup that trips up scanners without true simulcast handling.

Encryption in Louisiana

Statewide, Louisiana lands somewhere in the middle on encryption, but that average hides a clear pattern. The New Orleans metro parishes and East Baton Rouge Parish, the two largest population centers in the state, have moved most or all law enforcement talkgroups behind encryption. Shreveport, Lake Charles, St. Tammany, and the bulk of rural LWIN parishes still run open, so a standard trunk tracking scanner will follow dispatch there without issue. Lafayette sits in between, with some talkgroups encrypted and useful traffic still audible on the rest.

Fire and EMS dispatch tends to stay open even in encrypted parishes, since that traffic is less often restricted than law enforcement tactical channels. If you live in or near New Orleans or Baton Rouge, set expectations accordingly before you buy.

Which Scanner to Buy for Louisiana

Between LWIN, the New Orleans Region 1 simulcast system, and Caddo Parish's independent network, Louisiana asks a scanner to do a lot of different jobs depending on where you point it. We recommend the Uniden SDS150 or SDS100 for exactly that reason. Both use Uniden's True I/Q platform, which was built to pull a clean signal out of simulcast environments like the New Orleans metro, and both track P25 Phase I and Phase II out of the box, so they cover LWIN and Caddo's independent system without extra configuration.

The SDS150 adds built in GPS, so it can automatically load the right system as you cross parish lines, along with a charging cradle and the Waterfall display for spotting activity fast. The SDS100 is the lighter, lower cost option with the same core P25 decoding performance, a solid pick if GPS auto switching and the extra hardware are not priorities for you.

Would rather skip the setup entirely? Zip Scanners' programming service loads your scanner with the correct system and talkgroups for your parish before it ships.
