Wireless communications


COPPERNIC offers a wide range of the most recent and efficient wireless communication technologies. They will be individually or simultaneously integrated into its mobile solutions to fit the specific needs of its customers.

Bluetooth technology

Bluetooth is a short-range radio technology dedicated to make connexions between electronic devices easy. The 1.0 version of this standard has been published in 1999 by the « Bluetooth Standard Interest Group » (SIG). The Bluetooth technology reaches its maturity in 2006 when the 2.0 specifications have been published. This new generation offers a throughput that will be up to 100 times better than the previous one…. It’s still evolving over the years and its 3.0 version that has been published in 2009 addresses some new multimedia applications for consumers.

Targeted applications

For the professional mobile market, the Bluetooth technology is mostly dedicated to connect external peripherals such as printers, data capture readers (barcode, RFID...) or to connect a batch device to WiFi or WWAN networks through a Smartphone.


  • The Bluetooth range depends on the class of the two connected equipments: Around 300 feet (100 meters) for class 1, 30 feet to 65 feet (10 meters to 20 meters) for class 2, up to 10 feet (3 meters) for class 3
  • The theoretical output is 1 Mb/s for the 1.0 version and about 3 Mb/s for the 2.0 version
  • The frequency hopping modulation method on 79 channels guarantees a good immunity to WiFi networks which are using the same 2400 to 2483,5 MHz frequency range but a direct sequence modulation type.
  • Each Bluetooth interface has a unique MAC address that is used for the pairing with the other equipments.

WiFi technology

WiFi is a radio technology that is dedicated to connect different computing equipments within an area covered with a LAN (Local Area Network). These connections are managed through routers called access points or directly in a peer-to-peer mode. The WiFi technology is governed by the IEEE 802.11 official standard. 

Targeted applications

For professional applications, WiFi technology is dedicated to permanently connect mobile devices to the IT network of the Company, or to punctually synchronize these devices for updating their data and applications. It may sometimes be used to connect peripherals such as mobile portable printers in peer-to-peer mode.


  • The range and the throughput depend on the standard: up to 11 Mb/s (6 Mb/s actual) for 802.11b, up to 54 Mb/s for 802.11g or 802.11 a (25 Mb/s actual)
  • 802.11b and 802.11g are both using the 2400 to 2483,5 MHz frequency range when 802.11a uses the 5150 to 5725 MHz frequency range.
  • The emission power being limited to 100 mW, the throughput automatically drops when the distance between the transmitter and the receiver goes up. The maximal range is about 300 feet (100 meters) in an industrial environment.


GSM is a radio technology that allows voice and SMS communication between cellular phones and through networks of antennas, called base stations and that are largely deployed by the major carriers in each Country. They work on 900 MHz and 1800 MHz frequencies in Europe, 850 MHz and 1900 MHz in North America.

GPRS allows data communication through the same GSM infrastructure. The users will easily be connected to Internet and to the IT System of their Company.

EDGE technology is an evolution/improvement of GPRS that increases the actual throughput.

Targeted applications

GPRS et EDGE technologies, respectively called 2G and 2,5G, allow nomadic users to synchronize their data with the Information System of their Company.


  • GRPS offers a 171.2 kb/s theoretical throughput but its maximum actual throughput is around 50 kb/s
  • EDGE offers a 473 kb/s theoretical throughput but its maximum actual throughput is around 384 kb/s.


UMTS and HSDPA technologies have higher throughput that allow multimedia communications (MMS, online video, etc...). Frequencies are 2100 MHz in Europe, 850 MHz and 1900 MHz in North America.

Targeted applications

UMTS and HSDPA technologies, respectively called 3G and 3G+, are more and more required for professional mobile applications as their performance allow real time data communication between the mobile worker and the IT System of the Company.


  • UMTS offers a theoretical 1920 kb/s throughput but its maximum actual throughput is around 1 Mb/s
  • The HSDPA offers a theoretical 14.4 Mb/s throughput but its maximum actual throughput is around 3.6 Mb/s
