The P-N31 represents the next generation of portable full-band interference technology. Built as the advanced successor to the P-N28 platform, this model integrates 31 independent frequency channels, expanded antenna architecture, and a high-capacity lithium battery into a compact, field-ready aluminum chassis.
Designed for modern wireless environments, P-N31 delivers reliable suppression across 5G Sub-6 GHz networks, Wi-Fi 6E/7E, satellite positioning bands, LoRa, FM broadcast, and legacy cellular standards — making it one of the most comprehensive portable solutions available as of 2026.
Unlike conventional portable units that focus only on mobile networks, P-N31 extends coverage into newly deployed spectrum ranges such as n77/n78/n79 5G bands, 6 GHz Wi-Fi, extended GPS frequencies, and long-range IoT communication channels.
Key Advantages
