Dolphin Telecom continued to stake its claim as a key player in the corporate telecoms market. Besides offering network provision solely for businesses, Dolphin provides telephone/two-way radio handsets which give push-button one-to-one or one-to-many digital radio contact nationally.
Text messaging and instant callback is also offered with one-to-many. Unmetered virtual private mobile networks can be supplied in vertical sectors and individual companies.
SmartCall International was showcasing its Cellu-Link system which offers businesses a dedicated wireless link to employees' mobile devices.
Installed hardware routes telephone calls directly to the cellular network via an array of 30cm rooftop aerials, missing out the landline part of the call.
The company claims savings of up to 50% on telecoms bills are possible this way across the Vodafone, Cellnet, Orange and One2One networks.
Mobile data is the specialism of Newbury-based Cognito, which announced the release of its C21 data terminal in the UK.
The device allows data to be transmitted to field sites at GSM speeds allowing, for example, on-site engineering personnel to call up systems diagrams or to make amendments to customer data, as well as providing access to e-mail and text messaging services.
The company has recently been testing a GSM over Internet protocol version, the G21, but it has yet to finalise a release date.
