Private Mobile Office

Private GSM network solutions for in-building communications

Private Mobile Office (PMO) provides a complete, packaged, private GSM network solution for use within an office, warehouse or campus area to support communications between workers and to extend or replace the current PBX infrastructure, or to offer an effective alternative to Digital Enhanced Cordless Telecommunications (DECT) and Private Mobile Radio (PMR) installations.

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

The mobile handset has established itself as the device of choice with business users. However, in-building installations have, up till now, relied on DECT or PMR systems to achieve mobility.

The Private Mobile Office solution is both cost-effective and a sound technical alternative to DECT or PMR. The solution provides businesses with a competitive edge through cost effective utilisation of standard mobile phones and the improvement of in-building coverage through GSM technology. Mobile handsets operating on Private Mobile Office can, optionally, be integrated with the incumbent PBX infrastructure or directly to the carrier network for offsite calls.

Private Mobile Office has a number of powerful telephony applications available to overlay and integrate with both the private mobile network and the PBX infrastructure to add in-building and offsite flexible working support through intelligent call routing and advanced telephony capabilities.

Key Benefits

• Enables call cost savings; mobile services at no charge when in range of the private mobile network, and at landline rates when passed out through the local PBX.
• Automatic switch over to private network when in range ensures costs are optimised. Utilises standard mobile phones - existing business mobiles or ruggedised versions.
• Use of mobile phones ensures long battery life and extended handset choice compared with alternative solutions.
• An effective range of up to 350m omni directional ensures superior coverage. Operation is immune to interference from WiFi or video senders.
• A cost-effective alternative to DECT technology for in-building or campus use. Using mobile handsets extends the functionality of legacy equipment, which impacts positively on operational costs.
• Business-critical continuity is maintained on occasions when the macro network is not available.
• Remote workers can become more productive, more time-efficient and more capable of delivering benchmark customer service because they have access to their employer’s data network via GPRS services on their mobile handset.
• Ability to be deployed very quickly, making it an ideal solution in transient or temporary site situations.

How PMO Works

Using one or more base stations, strategically placed to ensure full network coverage, PMO registered mobile handsets are able to communicate with each other in a localised GSM ‘island’. Through an additional connection to a local PBX infrastructure or a PSTN gateway, the handsets can also communicate with internal PBX extensions and the outside world.

PMO handsets are standard mobile GSM phones and are used, for calls and SMS messaging, in exactly the same way they would be within a macro mobile network. To ensure that the network is secure from unwanted parties, PMO SIMs are pre-registered with the network and only handsets with registered SIMs can utilise network functionality. Pico cell base stations are placed to give maximum coverage and to act as an interface between the handset and the PMO network. Callers are able to roam anywhere within the PMO network with call control being seamlessly handed between base stations.

PMO handsets become extensions of the PBX, without the limitations of fixed lines but with all the benefits of a shared, extended network. As PMO can also connect to a carrier network or PSTN, it can be used to effectively replace a PBX to create a fully mobile workforce.
