Closed user group network operated at LTE frequency bands
A private closed user group LTE network with an HSS (Home Subscriber Server) significantly enhances confidentiality and data protection for registered subscribers within a controlled group across specific indoor or outdoor areas. By default, the LTE segment is isolated from external cellular networks to minimize the risk of unauthorized intervention.

When registered with a private LTE network node, subscribers can use any commercially available cell phones that meet the following requirements:

• The handset can be tuned to operate in the required LTE band.
• It supports SIP-telephony, Skype, or other instant messengers that are not tied to MSISDN.
• It uses the Android or iOS operating system.
• It can access the public network through a private PBX.
• It can use a USIM card issued by the end user.
• It can operate in LTE-only mode.
• It has a SIP client installed to communicate with SIP PBX Key Services.
• Voice communications
• Data exchange
• Data channel between the server and subscriber equipment
• Support of own Home Subscriber Server to manage authentication and ciphering
• High speed Internet access using own communications channels
• Fully autonomous mode or integration with existing telecom networks
• Access to all known wireless messengers bypassing real operator’s network.
• Base stations subsystem
• Communications server
• USIM cards
• Internet access gateway
Base station subsystem is functioning according to 3GPP 36.101 recommendations and is set to operate at frequencies not used by other wireless carriers in the area, or when such channels demonstrate very weak signal strength. In order to use frequency resources more efficiently, Micronet-LTE employs TDD LTE mode.

The network can use 10 or 20 MHz spectrum. The more spectrum is used the higher the overall data throughput can be achieved. Implementation of own authentication mechanisms within private switching subsystem allows to fully control all communications sessions within private network. Number of simultaneous connections per base station is up to 96 (TDD) and 128 (FDD).

Starting configuration includes 8 base stations with possibility to expand at later stages. Micronet-LTE is operated at 2300-2400 MHz band, other bands (700, 850, 1800, 2100 or 2600 MHz) are optional but can be implemented as well. The system features up to 100 Mbps data throughput depending on frequency band.
Micronet-LTE is designed to ensure secure and reliable wireless communication for users with a group. Our solution supports two-factor authentication, as well as other access controls such as role-based and attribute-based access control, ensuring that only authorized users can access sensitive information and resources. The Micronet-LTE network node is equipped with encryption capabilities that protect data in transit and at rest, using advanced encryption algorithms to ensure confidentiality, integrity, and authenticity. We also offer regular updates and patches to prevent vulnerabilities from being exploited and to maintain the highest level of security possible. Our comprehensive training and support ensure that user is aware of network security and can take steps to prevent insider threats.
Micronet LTE cluster can be used as a backup communications network during emergency situations as well as highly protected private network serving thousands of registered users using dual SIM cellphones
Support for both voice and data allows the Micronet-LTE distributed network to be used within mines, power plants, and other industrial facilities. In this case, it is possible to provide high network security and take intra-facility communications to a new level by replacing portable LMR radios and leaky feeder setups
Micronet-LTE serving cell, operated at frequencies offset from the current frequency plan, can be installed in one of the VIP or military convoy vehicles. This enables vehicle-to-vehicle communications, independent internet access, and access to other public telephone networks.
