Fortress LTE 20W eNodeB (RN2420)

Connectivity with Certainty

The Fortress® 20W eNodeB (RN2420) is a member of the Fortress LTE family of high performance Evolved Node B (eNodeB) base stations. The RN2420 is a Size, Weight and Power (SWaP) optimized, single carrier LTE base station that houses digital baseband and Radio Frequency (RF) circuits in a compact, environmentally hardened enclosure. The small size of the RN2420 makes it ideal for public safety, tactical cellular and private network deployments worldwide.

Product Details

About General Dynamics Fortress LTE

Ideal for small to large specialized private wireless deployments, Fortress LTE delivers an end-to-end solution providing ‘always on’ high speed network access to vital information including voice, video, data, text and chat using any 3GPP compliant LTE enabled device. Fortress LTE solutions are frequency agile, customizable for specific applications and designed for harsh, permanent or temporary deployments where network access may not be available. Fortress LTE is a cost-effective, single vendor end-to-end solution consisting of:

  • 4G Core Network
  • Radio Access Network (Base Station)
  • User Equipment (UE)


  • SWaP Optimized - Reduces overall system size, resulting in decreased deployment time and cost
  • Ideal for public safety, tactical cellular and private network deployments worldwide
  • Available in a broad range of frequencies
  • Waveform Hardening - Enables operation in the presence of deliberate jamming attempts

What Sets Us Apart

  • Compact Design – The RN2420 eNodeB combines digital baseband processing and radio circuits into a compact rugged, water and dust resistant enclosure. The Size Weight and Power (SWaP) optimized design and high performance enable the RN2420 to meet operational requirements using the minimal amount of eNodeB’s, reducing system size, setup time and cost.
  • High Performance – The combination of the high performance and compact size of the RN2420 eNodeB allow it to meet any operational requirement using the minimal amount of eNodeBs. This optimization minimizes the system size, reduces deployment and training time and saves cost.
  • Standards Compliant – The RN2420 eNodeB complies with the global 3GPP LTE standards to ensure interoperability with 3GPP compliant User Equipment over the LTE air interface protocols. The RN2420 eNodeB implements the standard S1 interface to the Mobility Management Entity and Serving Gateway in a 3GPP Evolved Packet Core.
  • Interference Mitigation - The RN2420 eNodeB implements sophisticated real-time algorithm to detect and avoid external interference. This agility allows the RN2420 to coexist with other systems or to respond to deliberate interference or jamming attempts.
