2G / 3G / 4G LTE 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
• Options available for 2G / 3G / 4G LTE

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.
Design and consultancy – Technical support – Sensors – Data – Airtime – Transfer / share – WirelessData
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.

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 Bluetooth-
enabled 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® connectivity solutions
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.
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 mid-
to 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.

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
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.
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

mandates the use of an on-board antenna. These antennas can
be chip, patch or PIFA antennas, or embedded into the PCB itself.
Many factors affect the performance of these types of antenna
including ground planes, position of other components,
orientation of the unit, materials used in the outer casing, and
proximity to the outer casing.
A poorly optimised or tuned antenna will have adverse effect on
the wireless range and power consumption.
Acal BFi, through our antenna suppliers, have access to the latest
RF antenna modelling tools to help you determine the optimum
antenna for your system.

alternatives. Typically MEMS-based oscillators offer the following
benefits over their quartz-based equivalents.
• Better frequency stability over temperature
• Lower phase noise and jitter
• Lower power consumption
• Superior resilience
• Superior vibration sensitivity
• Superior shock sensitivity
• Wide range of package types with ultra-small footprints
• Commercial, industrial, automotive and military temperature

Improve systems performance with a wide
portfolio of product solutions
In medium- and high-volume applications it is often more economical
to move away from a module-based solution towards a chip-set-based
solution. These solutions require good, affordable and stable frequency-
control solutions.
We have over 30 years of experience in working with frequency
control products from some of the world’s leading manufacturers. Our
engineers are available to help you identify the most cost-effective
products from our range, whatever your application.
Frequency control
Our extensive range includes:
• Ceramic resonators
• Crystal oscillators
• MEMS-programmable oscillators
• OCXOs, TCXOs, VCTCXOs, VCXOs
• Oscillators
• Real time clocks

RF solutions for IoT applications
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
Comprehensive range of RF components
We have over 30 years of experience in supporting RF design engineers on some of
the most innovative radio designs in Europe. We believe our technical expertise is
second to none, supporting our customers with expert advice, evaluation boards,
samples, data sheets and, where necessary, S-parameters.
Our RF product portfolio covers frequencies from as low as 100 MHz to as high as
30 GHz, and offers a broad product offering from world leaders in RF component
design.
The range covers:
• RF amplifiers, including general purpose, power and LNAs
