If your enclosure’s metal coverage is only partial, careful antenna location will still be critical, and it may still need to be external, depending on the exact geometry. The manufacturing industry needs digital and innovative solutions to facilitate flexible and transparent production… When adding multiple remote adapters to increase range or available connection slots, separate them enough to avoid interference with each other. Our collection of webinar recordings covers a wide range of topics presented by technical experts from Laird Connectivity. Learn about all things wireless - From industry insight to deep dive discussions on IoT gateways, Bluetooth modules, and more.
The Bluetooth integration supports receiving advertisement data from external adapters for devices and sensors that do not need an active connection, as well as establishing active connections. The number of remote scanners is limited only by the performance of the host system. Also, you need to do more than just adding the FL connector, just adding it, and an antenna will NOT work, as it was never meant to be an antenna connector.Despite these performance benefits, few new device launches feature external antenna. It's unlikely a product brief for a consumer solution would allow for one. Seamless connectivity, like they get in their smartphones, is something consumers now expect. They are also prone to damage and create large deformations, unsuitable for some applications. 4. Mount a multilayer antenna to the enclosure The Service Discovery Protocol (SDP) allows a device to discover services offered by other devices, and their associated parameters. For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them. Each service is identified by a Universally Unique Identifier (UUID), with official services (Bluetooth profiles) assigned a short form UUID (16 bits rather than the full 128).
But nothing comes for free: a loaded antenna means reduced bandwidth and reduced antenna efficiency. In some cases, that’s ok because: To answer that question, you need to consider how the manufacturers can shrink those tiny chips below 31 mm and sell them as 2.4GHz antennas. Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost. Laird Connectivity also provides a range of other solutions that utilize earlier iterations of the Bluetooth standard, including Bluetooth 4.0 and 4.2 and Bluetooth 2.0, 2.1 and 3.0. A full range of solutions that combine the capabilities of Bluetooth with other wireless technologies such as Wi-Fi and LoRa are also available from Laird Connectivity.
Please note:
The matching network is designed to optimize the antenna impedance to match 50 Ohms. For an acceptable S11/VSWR of the antenna, some antennas will be required to have a matching circuit. This is normally specified in the application guide. The application guide also references many other guides to achieve optimized antenna performance. The Bluetooth SIG released the Bluetooth Core Specification Version 5.4 on 7 February 2023. This new version adds the following features: [128] Manufacturer guidelines on ground plane length, width, clearance and matching components are usually defined to extract as much performance and signal out of your antenna as possible, but small antennas simply limit your efficiency and therefore your range.
