Reliability
NEXEDGE® systems use the NXDN® digital air interface, a suite of digital communications protocols using 4-Level FSK (4LFSK) modulation capable of operating in 12.5 kHz and 6.25 kHz bandwidths. NEXEDGE® voice security enhances personnel safety, reduces risk
and thwarts possible information breaches by protecting sensitive communications for your facilities and operations.

Rock Solid Stability
NXDN® is capable of both 12.5 kHz and 6.25 kHz bandwidth channel operation to ensure rock-steady frequency stability, exceeding all regulatory and emissions mask requirements in all bands. NEXEDGE® systems do not drift and cause adjacent channel interference issues in properly coordinated spectrum.
Channelize
NXDN® equipment will program on any channel center or offset (2.5, 3.125, 5, 6.25, 7.5 kHz PLL channel steps) providing more potential to find frequencies which is important where narrower channel migration is being forced or there is a need to maximize use of geographical licenses and use split-channels where permitted.
Voice & Data Security
The NXDN® digital air interface offers inherent security against casual electronic eavesdropping, and subscriber units also include the NXDN® 15 bit key scrambling function for secure voice & data. IP links are further secured through VPN tunneling to authenticate and encrypt all inter-site communication. Kenwood offers AES & DES encryption option modules for government-grade security against more sophisticated adversaries. These modules have a unique embedded crypto-ESN which will erase its encryption keys (zero-ize) if an attempt is made to place it in any other radio unit. In addition, if greater than 15 radio-password attempts are made, the module’s encryption keys are also erased, preserving the fleet’s current secure voice integrity.

All NEXEDGE® system configurations validate unit and group IDs for subscriber access. Commercial and private operators can easily activate & deactivate subscriber units via remote programming or system management software. This is ideal for organizations with frequent personnel changes, so radios can be used by contractors, vendors and seasonal/temp workers.
ESN Radio Validation
Each NEXEDGE® subscriber radio has a unique and unchangeable factory embedded Electronic Serial Number (ESN) that can be validated for trunked system access. In the event a radio is lost, stolen or compromised, disabling the ESN will deny access while all other radios continue to communicate in their talk groups without disruption. The operator’s original ID numbering system is preserved because only one subscriber unit is disabled and not one or more talk groups shared by many users.
Radio Password Protection
Each radio can have a required password to authorize operation, thus adding an extra level of security against unsanctioned radio use.
