2G / 3G / 4G LTE connectivity Connect your product anywhere in the world When considering connectivity options, it is important to consider when, where, what and how long devices will need to communicate. Those which are deployed worldwide can leverage the benefits offered by the global cellular mobile phone network. There are multiple options with this approach, including the use of a modem, gateway or embedded module. Modem options offer the easiest connectivity solution for a product with an existing serial port; similarly, a gateway approach can provide the same ease of access to IoT for products with an ethernet port or WiFi connectivity. Embedded solutions are also desirable for many customers and modules provide the most viable option to achieve this method of connectivity.

Modems and gateways – the simplest way for IoT cellular connectivity Modems and gateways offer the most convenient way for remote devices to connect to the internet via the cellular mobile phone network. Typically these modems offer ethernet-to-cellular connectivity or serial-to-cellular tunnelling with I/O capabilities. Fully standalone and ready to deploy, modems are designed for enterprise-class quality and reliability. Key features of our range of modems and gateways •

What you need for a successful cellular connectivity In order to have successful cellular connectivity the system designer should consider the three core elements concurrently, as all are required to work together for a successful cellular-based IoT implementation. Hardware – this is the electronics that gives your product or system the capability to connect to the cellular network. You will need to know the network variant (2G, 3G, 4G LTE) that you plan to use and the geographic region you plan to operate it in. Air-time services – these are the services provided by a network operator that will allow you to use the cellular network. Typically this relates to SIMs and air-time contracts. Cloud connectivity – this is the services provided by a hosting company to allow you to host data in the cloud.

Bluetooth® connectivity solutions Short-range wireless for cable replacement When looking for a simple wireless cable replacement, one of the best solutions is Bluetooth because of the light-weight stack and the proliferation of Bluetoothenabled products. With the arrival of Bluetooth 4.1 (also known as Bluetooth LE or Bluetooth Low Energy) it is now also suited to very low-power applications, such as connecting remote sensors to intelligent peripherals such as smartphones and tablets. We offer a range of Bluetooth modules with embedded Bluetooth software stacks from Fujitsu, Skyworks and USI. For more details on Bluetooth beacons see page 17.

Bluetooth 4.1 modules These ready-to-use modules are perfect for quickly adding Bluetooth 4.1 functionality to any product with a serial port (UART, SPI, USB). The module is pre-configured with Fujitsu’s data communication (FDC) profile. This is an SPP (serial port profile), ideally suited for sensing, monitoring and wearable applications.

Chip-based SIP modules For applications requiring a higher degree of flexibility and customisation Acal BFi offer a range of Bluetooth 4.1 modules from USI. These modules use the latest WICED™ chipsets and support application specific code developed using the WICED™ development platform. With a compact form-factor and built-in antenna these modules are ideal for midto high-volume applications that require customised functionality and low power consumption. Modules are available as Bluetooth only or dual Bluetooth / WiFi.

Front-end modules Designed with cost and space savings in mind, Skyworks Front-End Modules combine the company’s industry-leading power amplifier (PA), low noise amplifiers (LNA) and switch functions into single low-cost, laminate-based multi-chip modules (MCM). Furthermore, the new module requires no external matching components, accelerating time to market. Manufactured using Skyworks’ proprietary heterojunction bipolar transistor (HBT) power amplifier process and low-loss pseudomorphic high electron mobility transistor (PHEMT) switch technologies.

Bluetooth 4.1 explained The popularity of Bluetooth technology continues to grow aggressively year on year, but it’s the recent evolution and release of Bluetooth 4.1 that has captured the imagination of IoT developers around the world. Bluetooth 4.1 allows for short transmissions of data rather than a continuous data stream. This key change reduces power consumption and improves efficiency, a necessary quality for IoT applications such as wearable technology. Embedded into all of Apple’s operating systems as well as Windows 8.1 and Android 4.3, this low-energy, short-range wireless technology is set to continue as one of the most popular wireless connection methods the world over.

ISM modules Our off-the-shelf modular ISM solutions cover the following standards: •

Wireless MBus (169 MHz and 868 MHz)

Zigbee / 802.15.4 ready modules (868 MHz, 915 MHz and 2.4 GHz)

LoRa® / LoRaWAN™-ready modules

SIGFOX-ready modules

Low-power, wide-area networks (LPWAN) explained Many existing M2M and IoT applications only require low bandwidth as they are transferring small amounts of data. With low bandwidth and small data packets comes the opportunity to look at alternatives to cellular based networks, including SIGFOX and LoRa®. These technologies and networks operate on frequencies in the ISM band and use ultra-narrow band (UNB) technology. Typically these networks operate in a star format where client devices connect via the UNB technology to gateways, which then connect to the cloud. Whilst the technology is restricted to geographies with installed networks capable of using these protocols, the advantage for client devices is simpler hardware and software, and much lower power consumption than traditional cellular networks. This makes it ideally suited to remote monitoring applications with low bandwidths and small data requirements.

Beacons Bluetooth® beacons for IoT solutions Driven by the popularity of smartphones, beacons provide marketing messages and indoor location information to any Bluetooth-enabled smartphone. Inside every beacon is a Bluetooth LE transmitter. We offer two products to enable rapid development of beacons.

Smart sensor beacon FWM8BLZ02-109047 A complete, production-ready beacon with the following unique features: •

Possible to set arbitrary advertising data / scan response data

Easy beacon setting / maintenance by text-based command

Remote updating and configuration

Three operating modes selectable: Broadcast mode – sending advertise data one way Peripheral mode – sending and receiving data bi-directionally Recovery mode – initialise beacon setting

Bluetooth LE module MBH7BLZ02 The ideal embedded module for use inside a beacon with all the features required to support beacon functionality.

Beacons explained Beacon technology allows mobile apps running on a smartphone to listen for signals from beacons in the vicinity and then react accordingly. Based on Bluetooth LE, the system effectively allows the mobile app to understand its position on a micro-local scale and then receive hyper-contextual information, based on the location. Using a standardised format for Bluetooth LE advertising, the beacon broadcasts an advertising packet at frequent intervals, typically 100ms. The advertising broadcast contains a unique ID (UUID), which is identified by an app running on a smartphone which then triggers push messages, app actions or prompts. Bluetooth LE-enabled devices typically have ranges of 100m, making the technology ideal for indoor location tracking and awareness. The powerful nature of the beacons is that any app running on the smartphone will be able to understand exactly where the customer is in a given physical environment and then deliver a highly contextual, hyper-local and meaningful message.

FEMs simplify product design and manufacture Front-end modules (FEMs) is the name that is increasingly being adopted by manufacturers of RF sub-systems. These sub-systems are generally application-specific and designed to support one or more specific frequency bands or base-band chip sets, particularly in the ISM, ZigBee and WiFi space. These modules are the ideal complement to the chip sets as they are complete, fully tested and matched radio sub-systems, which generally offer power and space savings over discrete designs. Typical features include: •

Complete RF sub-system including LNA, filters and switches

Pre-configured, matched and aligned reduces final test time

Low current consumption extends battery life

Small, low-profile packages reduce footprint

Available for all common RF technologies including Bluetooth, ZigBee and WiFi
