eDevice's BridgeD130 allows users to switch from PSTN to GPRS without any changes to their infrastructure.
eDevice has released BridgeD130, a PSTN2GPRS convertor that connects wired modems to wireless networks.
This product allows users to switch from PSTN to GPRS without any changes to their infrastructure.
eDevice will take part in the Metering 2007 trade show in Vienna from 2nd to 4th October 2007.
Devices that were previously plugged into the wired phone network can now benefit from the flexibility, mobility and rates of GSM/GPRS networks.
This saves the cost of a GPRS upgrade of the existing device, extending the lifetime of equipment.
Wireless carriers will be able to compete for market share that was previously reserved for landline connectivity.
Handset-like business models with monthly fees can be successfully applied by cellular carriers for device connectivity.
Migrating to GPRS allows users to benefit from cellular coverage area, mobility and adapted GPRS rates, as compared to PSTN monthly subscriptions.
It also dramatically simplifies the installation stage and the billing process, as well as enabling convenient incoming call support.
This migration also improves central servers' architecture, as racks of modems are replaced by high-bandwidth internet links.
The BridgeD130 has been engineered to eliminate the need for wired subscription without requiring any changes to either the device or the central server.
The cable that is usually connected to the wall socket just needs to be plugged into the BridgeD130 phone interface, while an eDevice software component can be installed on the remote central server to add TCP/IP support.
Devices that are usually connected to a PSTN/POTS network can connect to the BridgeD130, as it emulates the analogue phone network with an Foreign eXchange Station (FXS) interface.
The BridgeD130 not only generates rings, dial tones and power, but also extracts the data from the modem flow to transfer it over the GPRS link.
This M2M terminal is based on the eDevice TCP/IP stack, including a web server and remote firmware upgrade support.
The BridgeD130 integrates a quad-band GSM/GPRS module and can be battery powered.
