Private Mobile Networks Supports Macro GSM for Connecting Between Networks

Private Mobile Networks, the UK provider of private GSM network technology, has announced support for GSM operator networks as an interconnect between distributed Private Mobile Network sites. Private Mobile Network traffic can now be distributed between locations over satellite or IP, or break out and pass over a national Macro GSM network.

"The use of PMN, whether from an office, in a vehicle, or as a rapid deployment unit, will usually require some form of backhaul of network traffic to a network operations centre or head office infrastructure," explained Chris Moore, sales director for Private Mobile Networks. "As far as PMN is concerned, as long as IP is supported, then the type of backhaul becomes almost irrelevant. Being able to connect over mobile, through the mobile interfaces at our UK data centres, extends the options available to our customers," adds Moore.

Network or bandwidth considerations will, typically, determine the services and functionality that will be delivered over backhaul, but the actual delivery of signalling will be exactly the same as over a standard wired Ethernet network.

The PMN Ethernet connectivity allows it to be connected through external communication devices such as satellite, microwave or wireless in remote locations, or a fixed IP Backhaul such as IP Broadband or a VPN where available. PMN delivers Private GSM. To extend the Private GSM network into a multi-site network or give it connectivity to the outside world requires an interconnect that provides a secure service.

Satellite is a global method of backhauling IP traffic and is the preferred method for many PMN deployments due to its flexibility, ease of setup and relative cost. Terminals can range from large-scale fixed installations to notebook-sized BGAN terminals with varying levels of frequencies and bandwidth available. The military, for instance, have dedicated frequency bands and satellites to route their secure traffic.

Private Mobile eXchange (PMX) is a mobile network switching subsystem, implemented in software, with all the components for switching mobile calls, switching short message service calls, storing and transmitting SMS and providing Packet Data (GPRS and EDGE) in software, complete with translation and routing tables to act as a replacement PBX and/or MSC. PMX is a GSM product - 2G and 2.5G (with packet data optional). The GSM voice calls and SMS are compatible with both 3G and 2G phones and terminals.

PMN solutions are deployed in the UK under the TeleWare low power GSM spectrum licence. Overseas, local low or high power spectrum licences are required.

Private Mobile Networks-Private GSM and IP Solutions

Private Mobile Networks (PMN) provide the ability to access voice services using mobile handsets over a private GSM network. With PMN, the mobile phone can be the handset of choice for financial and practical reasons by replicating a cellular network in software and inter-operating with IP/SIP devices and applications.

PMN can be deployed into areas where network integration and infrastructure costs would otherwise be prohibitive or into areas of high mobile usage with poor or no GSM network coverage, such as warehouses or in-building areas with signal disruption. The solution is ideal at temporary locations, such as in the construction and outdoor events industries. In areas where voice privacy is an issue, PMN can be implemented as localised islands of communication with the inherent security of GSM.

At the heart of the Private Mobile Network is the Private Mobile eXchange. PMX creates a self contained, privately owned and managed mobile network based on standard GSM protocols. The solution comprises both hardware and software components. The components are:

Base transceiver station (BTS) mobile phone access pointsBase station controller (BSC) to manage the BTSsPMX software run on industry standard servers

A Pico cell (BTS) connected to a local IP network delivers signal over low powered GSM. PMN can be deployed using a local server or as a hosted service delivering a Private Mobile Extension.

Increase in-building coverage using mobile handsets operating as PBX extensions also increases the ability to contact employees, reduces time to respond to customer and colleague queries, and provides a platform for quicker decision-making. A PMN also gives enterprises the ability to control and monitor and the potential to decrease mobile spend selectively.

PMN enables mobile phones to become part of the internal telephony infrastructure while near the workplace. Users are able to access the same services and features using a fixed extension on the corporate PBX or on their mobile phone. PMN can be implemented either by replacement of the PBX or by integration with the existing PBX infrastructure.

Use of applications on the mobile phone can be simplified using Mobile Office software which provides a menu-based interface to conferencing, call recording and call transfer and delivers this functionality to mobile handsets even when roaming.

Features and benefits:

Allows mobile phones to operate as PBX extensions while on-siteCorporate phone bills are reducedEase of use of devicesConsistent telephony user interface, irrespective of device, network or locationHigh level of customer service from improved staff contactBusiness continuity as the PMN continues to operate when the macro network is unavailableFixed Mobile Convergence with 2G and 2.5G handsetsPMX is built on industry standards, protecting investment with its ability to accommodate future developments

Many organisations benefit from a mobile, yet fully contactable, workforce and PMO has been designed to fulfil this requirement, providing in-building/on-campus communications.

PMO can extend or replace the current PBX infrastructure, providing an effective alternative to cumbersome Digital Enhanced Cordless Telecommunications (DECT) and Private Mobile Radio (PMR) installations used today.

Standard GSM mobile phones, including ruggedized handsets, connect users together on a secure, private network without incurring mobile phone call charges. Voice quality is high, as expected, on an industry standard-based GSM network, and support for PTT, SMS and GPRS is available.

Using one or more base stations PMO registered mobile handsets are able to communicate with each other in a localised GSM ‘island’. PMO provides cost effective utilisation of standard mobile phones and the improvement of in-building coverage.

To ensure network security only registered handsets can be connected. Pico cell base stations provide the interface between the handset and the private network. Callers roam anywhere within the coverage area with call control being seamlessly handled between base stations. The PMO can integrate alarm and notification systems.

Brazilian Operators Introduce Fourth-Generation Mobile Communication Standard

The mobile communication standard of the fourth generation is being introduced by all leading operators in Brazil.

In June 2012 Telecom regulator ANATEL conducted a frequency auction for the 2,500MHz and 450MHz frequencies to be used for the 4G networks. Besides the established mobile network operators Vivo, Claro, Tim and Oi, pay TV providers Sky and Sunrise were also able to secure licences for some attractive local markets.

Driven by the increased data hunger of mobile devices as a result of broadband applications such as social networks, video-streaming and also mobile TV, the network rollout is now rapidly getting underway after the auction. In urban areas, licences came with requirements for preferred coverage of venues for the Confed Cup 2013 and World Cup 2014. There are also requirements to provide service in rural areas.

Besides frequency allocation, ANATEL in Brazil is responsible for approving the products and vendors of the networks. Due to the fact that low-grade and cheap components led to problems with network quality (call drops, static, low data rate) in the past, ANATEL is placing large emphasis on the use of high-quality technology.

This is the value add that SPINNER offers: high-quality and high-performance components and passive RF solutions. For the infrastructure of outdoor base stations SPINNER provides connectors, jumper cables and accessories with outstanding RF properties so you get the best connections with a minimum of installation effort. For in-building and network combining, SPINNER offers its extensive and high-performance MNCS® portfolio.

As a result of the introduction of LTE, the need is increasing to be able to combine a sharply increasing number of networks with low levels of loss and without interruptions and to distribute these signals within buildings and structures of all kinds. In order to achieve this most effectively, the MNCS® solution offers the best credentials having already proven itself worldwide, and is also the best option for the Brazilian market.

SPINNER not only sells hardware, but is also a top service partner: Together with our costumers we create the best suitable solution for a very diverse spectrum of applications. The modularity is future-proof. SPINNER can allow its experience to speak for itself both in classical installations as well as with MIMO solutions. We have already been able to delight and enthuse our customers on the strength of a large number of our reference projects.

MNCS® is ideally suited to meet the increased quality requirements of ANATEL and Latin American customers. The focus of all SPINNER products is on low PIM (passive intermodulation), low levels of insertion loss and high isolation of the different carrier signals - between the bands, as well as within the bands.

SPINNER has already adapted its components to the increased power requirements. Together these features improve speech quality, result in less call drops and provide high data rates. Please visit our website or contact our local colleagues. We would be happy to explain our products and our solutions to our customers in a personal conversation.

SPINNER-RF Components for Mobile Communications Networks and Broadcasting Sites

SPINNER is one of the largest manufacturers of RF components for mobile communication networks and broadcasting sites. We can supply coaxial connectors and adaptors, coaxial cable assemblies, low-intermodulation jumper cables and surge protectors.

Our current product range includes coaxial connectors from 3.5mm through 230mm (SMA through 9in and the respective coupling elements). The main applications are mobile communication, broadcasting and radio links as well as radar and medical technology. Our connector series complies with the applicable DIN, CECC or IEC standards.

Our range of coaxial measuring devices includes all coaxial loads from 2W through to 50,000W, such as bridge resistors or power absorbers with convection or water cooling. In addition, you will find symmetrical and asymmetrical dry attenuators (5W through 2,000W) as well as directional couplers and filters.

SPINNER specialises in producing coaxial cable assemblies. We offer our customers a broad range of ready-for-use cable assemblies at favourable prices. Our product range includes cables of all sizes with various connector types that can also be made to customer-specifications at short notice. Besides mechanical requirements, the specifications can also include high-frequency related parameters such as reflection factor, insertion loss, electrical length, etc.

SPINNER has more than 12 years of experience in manufacturing low-intermodulation jumper cables. Special connectors and soldered conductors guarantee superior loss and outstanding long-term intermodulation performance even under adverse environmental conditions. All jumpers are automatically tested by highly sensitive measurement equipment to ensure SPINNER delivers the finest products on the market.

For Tetra systems SPINNER offers surge protectors with a quarter wavelength stub featuring low reflection and excellent protection properties, as well as very compact design. Surge protectors become increasingly important against overvoltage in coaxial transmission systems. It is mainly exposed antennas and masts of mobile communication base stations that are threatened by lightning damage.

Quarter wavelength stubs have proven to be very effective because they divert high currents to ground. Another advantage is the low residual pulse energy lead to the protected side. In addition to the well-known product range for the mobile communication networks GSM900, GSM1800, UMTS and WLAN, SPINNER can now offer a surge protector with a quarter wavelength stub for the Tetra network, too.

The well-designed combination of transformer elements allows us to cut the length of the stub, which would usually have to be about 20cm for the Tetra network frequencies, to one third. The resulting compact shape opens up possibilities of using the protector in locations where low weight is an advantage and where only limited installation space is available.

Smartphones and tablets have triggered a boom on the mobile communications market. The need for area wide network coverage and large bandwidths is still increasing. Classic telephony and internet applications are being replaced by mobile devices. Use is at the same time increasingly shifting indoors and buildings must be equipped with their own antenna systems.

For in-building coverage, SPINNER has been offering solutions under the trademark MNCS® for the sharing of different networks, frequencies and bands. Complex multi-operator systems are our strength as well as components for signal distribution.

The SPINNER group is headquartered in Munich, and with production facilities in Germany, Hungary, the US, China and Brazil, we now have over 1,300 employees worldwide.

Our subsidiaries and representatives are present in over 40 countries and provide our customers with an international network of support. Quality, flexibility and service have made the group internationally successful, especially in mobile communication and broadcasting.

The quality assurance (QA) system at SPINNER has been certified according to DIN EN ISO 9001. The results of our endeavours are documented in our DIN EN ISO 14001 certified environmental management system.
