Our All-IP wireless network products enable wireless operators to deploy revenue generating services supported by 2G and/or 4G technologies. All our products combine industry standard protocols and interfaces and leverage a distributed network architecture to deliver cost-effective infrastructure solutions over IP networks.The products are divided into three categories:

Core Network – These systems such as the MSC or EPC provide the management and control over services deployed in mobile networks. Our HSS/HLR manage subscribers.
Radio Access Network – RK Telesystem provides an array of unique 2.5G and 4G RAN products including billing and other network infrastructure
System Products – For unique applications, we have integrated RAN and core specific products for multiple industries for easy deployment and operation. These Network-in-a-Box are rapidly deployable solutions during emergency/disaster scenarios.

Our GSM radio access network solution replaces the traditional components of the GSM network(BTS and BSC) with a single product, the BTS.

  • Low backhaul requirements for the RAN
    local transcoders in the BTS
    local media routing
    BTS unit to BTS unit operations using the SIP call control protocols
  • Reduced power consumption
    65-80 Watts power consumption/ BTS unit
    works with solar panels
  • Small, lightweight piece of equipment for the radio access network
    measures 31cm x 20cm x 10cm
    weights 5 Kg
  • Affordable solution for GSM access network
    based on Linux OS
    IP connection to the core network the UCN – which is also Linux-based
    GTP and SIP protocols replace the costly SS7 MAP-A interface
    no base station controllers needed; BTS units communicate with each other directly using the SIP protocol
    reduced costs for technical staff and operations management
    software configurable from 1 to 4 transceivers
  • Upgradable to LTE
    The BTS units are software upgradable to LTE

Our base station is a complete 4G LTE eNodeB, containing both the radio and baseband functions. It can also be configured via software to operate as a 2.5G GSM/GPRS BTS+BSC.It has a maximum output power of 20 Watts RMS for LTE or GSM operation.

BTS is a software implementation of a GSM/GPRS radio access network based on BTS and is compatible with both 2.5G and 4G core networks comprised in our unified core network server. Resiliency, customization and technology independence are the main attributes of BTS.

Our BTS takes a GSM signal from your cell-phone or any other machine, and sends it through a VoIP connection anywhere in the world.

How BTS Works?

When you use your cell in a BTS network, the GSM signal reaches the antenna of the BTS. Afterwards, the signal passes up to Layers 1 and 2 where the GSM signal is processed and is fed through the socket to BTS. BTS renders the received connection with the protocol needed (SIP or another) to communicate with the outside server of the VoIP provider, for example, that links you to the person or machine that you want to communicate with.

BTS has been created with the purpose of delivering an enhanced and combined solution between L1 PHY, L2 Link Layer and L3 Radio Resource Manager, also know as MBTS, and Yate’s multiple features, such as the IAX over satellite, SS7 and Diameter, USSD, RManager, roaming or local phone switch.

BTS is a fundamental element in the UCN ,a single core solution for both LTE and 2/2.5 G networks.

It is is usually configured to operate in one of two modes:

  • Network in a Box (NIB) mode – In this mode,BTS acts as a self-contained GMS/GPRS network, connecting to the outside world over VoIP and/or ISDN protocols.
  • Radio Access Network (RAN) mode – In this mode, BTS acts as an element of a larger, multi-site GSM/GPRS network. Core network functions are provided by an outside server. This outside server can be either of:
    • UCN for for 2G SS7/MAP or 4G IMS/VoLTE mobile operate networks or
    • another BTS installation in NIB mode for multi-site private networks.

How the (UCN) Unified Core Network Works?

BTS transmits call traffic from the 2.5G mobile stations, as SIP, to OpenVoLTE. OpenVoLTE is our’s open license solution for Voice over LTE. In a 2.5G network, OpenVoLTE acts as a MSC/VLR. OpenVoLTE then communicates through SS7/MAP to OpenHSS, which is both an HSS and an HLR. The same SS7/MAP interface is used to perform roaming with outside partners.

For the transmission of data, through GPRS, the BTS base station communicates with OpenSAE, which acts as a typical 2.5G GGSN element, over a GTP interface, thus routing traffic to and from the Internet.

BTS covers all frequencies between 70 Mhz up to 3 GHZ.

Features and benefits

  • Software configurable as 4G LTE or 2.5G GSM/GPRS.
  • Software upgradable to future LTE and LTE-A Releases.
  • Can be used with any IP backhaul.
  • Local break-out of GPRS and LTE IP traffic for edge computing.
  • Local media routing for GSM speech calls.
  • GSM backhaul loading as little as 8 kbit/sec/call.
  • Can be powered from solar panels in most parts of the world.
  • Linux-based OS means lower management costs.
