Directional High-Gain antennaOmni-directional low-gain antennaFor use with blue2space products

Directional antenna

The directional antenna, developed in-house, is specially designed for longrange Bluetooth communication. Its higher gain extends the range of a

Bluetooth cell from the nominal 10-100 m to 250-1300 meters and even further(depending on the surrounding environment) without increasing the outputpower. With its 35 horizontal and 30 vertical transmissions, you can cover a

large area at a distance. Using a Class-2 Bluetooth radio, we achievedcommunication up to 1800 meters, using a Class-1 Bluetooth radio chip we

expect to reach even further.

Omni-directional antenna

The omni-directional antenna, also developed in-house, is specially designed

for medium range Bluetooth communication. Its 360-area coverage extends therange of a Bluetooth cell from the nominal 10meters to 48+ meters and even

further (depending on the surrounding environment) without increasing theoutput power. Using a Class-1 Bluetooth radio chip, we expect to reach well over

100 meters.

Antenna product combination

When a directional antenna is combined with a blue2link for long-range point-to-point or blue2access for long range LAN access, it retains all of theblue2links and blue2accesss capabilities, which means it can for example

constitute an extended-range Bluetooth link or Bluetooth LAN Access Point. This

configuration provides an extended kind of area coverage. A complete family ofsmart antennas, especially designed to support true mobile applications, ispresently under development.

KEY FEATURES AND BENEFITS

For more information about the blue2link or blue2access, we refer to the product sheets. Theinformation in this section mainly describes the added benefits of using a blue2link/blue2access

with directional antenna instead of just the omni-directional. The directional antenna providesextended-range network access for devices equipped with Bluetooth wireless technology. Different

versions (under development) of our antennas are suitable for different situations, which all have incommon that the physical shape and size of the Bluetooth cell is modified to suit the particularapplication. Connections over distances up to and beyond 1300 meters are now possible.

THE ANTENNAS

The blue2link with directional antenna is designed for point-to-point transmissions over long range.

It provides Bluetooth coverage within a relatively narrow angle (35 horizontal, 30 vertically). Thismakes the transmitted Bluetooth radio signals reach farther than they would if the standard version of

the blue2link was used. At the same time it makes it possible to receive weaker signals in thatdirection, such as the ones from Bluetooth units farther away than the normal Bluetooth cell size usuallyallows for. This is very suitable for, to mention a few examples, Bluetooth access in corridors, long-

range point-to-point connections (for example outdoors, or inside very large rooms, like warehouses),and public hotspots where the Bluetooth Access Point cannot be placed nearby.

The Blue2link with a high-gain antenna will also be available in a wide-area coverage version, whichwill provide Bluetooth access in a sector up to 180 wide. If this version is used as a Bluetooth Access

Point, the wide-area antenna with blue2access can be mounted on a building to give total coverage

in front of it or below. You could also mount the antenna on high buildings to create wide areacoverage for several other buildings.

USAGE SCENARIOS

Last Mile Solutions: The blue2link or blue2access with directional antenna could be used to

connect residential areas with a broadband base station and provide Internet connections withoutcables to every household. When extracting natural resources, control and monitoring of heavy

machinery and processes have until now been a matter of being at the site, or installing expensive

cable solutions to a control station far away. The Blue2Space product family offers an easy and low-cost solution. With directional antenna, blue2link, blue2access and blue2repeat, it is possible to

wirelessly control and monitor the extraction over 1300 meters and beyond. The same method can beused for other telemetry applications, such as remote reading of power, gas, and water meters.

Security: With the Blue2space product family, it is possible to build up the complete infrastructure ofa security system. No expensive cabling is needed, and therefore cannot be damaged or cut. The

Bluetooth wireless technology, with its encryption and frequency hopping techniques, provides for arobust and secure system. The products can of course be used to improve an already existing security

system. blue2access with directional antenna serve as an access points, and allow e.g. surveillancecameras, detectors and PDAs for security guards to interact wirelessly. They can also be used totransmit data, e.g. from a surveillance camera, wirelessly over long distances, if large outdoor areas

must be covered.

General Overview

The unit consists of a blue2link or blue2access with a high-gain antenna, instead of the standard internal omni-directional

antenna, you get a long-range beam point-to-point connection today, or point-to-multipoint with Bluetooth wireless technology

over large distances.

Several interfaces available today: Ethernet interface, RJ-45 connector. Serial interface (only blue2link), RS-232 (DTE/DCE) or RS-

422 connector interfaces. To be developed and under development: USB and Serial 485

With an embedded processor and operating system, which make the blue2link with directional antenna a true plug-and-play

device, no extra software is needed in the terminal or any other device connected to it.

All Operating environment, Bluetooth specifications, Hardware, Upgrade ability and configuration, Power supply and Ethernet

interface data are identical to the ones in the technical specifications for the blue2link, Ethernet version. For serial port

specifications, refer to the technical specifications for the serial version of the blue2link Directional antenna characteristics

Polarization: Vertical

Main lobe half power beam width: 35 horizontally, 30 vertically

Long-range capabilities, line of sight

A connection between two directional antennas, using Class-2 Bluetooth radio chip has a range of 1300. A connection between

one directional blue2link and one omni-directional blue2link both devices with Class 2 Bluetooth radio chip, has a range op to

150 meters.

Physical dimensions, weight and product code

Height: 345 mm

Width: 248 mm

Depth: 26 mm

Weight: 665 g (including blue2link)

Mounting restrictions

The directional antenna can be mounted a few centimeters from any wall, but conducting surfaces should be kept outside of a1-meter radius in front of the antenna, in order to preserve the radiation characteristics.Since the polarization is vertical, the antenna should be mounted with this in mind.
