Lets start by taking a look at the signal chain we all know very well. In nearly any customer system, they are going to need some type of connectivity – or interface components. This interface could either be wired, as in the case of the Interface block here, or wireless, in the case of the Wireless Connectivity block here. As I just mentioned – is that TI has the broadest wireless portfolio in the industry. Through merging technologies from LPRF and ECS – TI can address a large breadth of applications to allow customers to wirelessly connect everywhere.

The key goal of this training is to familiarize you with this slide, so that you may present the entire Wireless Connectivity portfolio confidently to your customers. In the grey section near the top of the slide, you can see where we’ve grouped TI’s Wireless Portfolio based on the wireless frequency bands used by each technology, like sub 1GHz, 2.4GHz, 5GHz or Satellite. In the red section, you can find a list of either the actual technologies or protocols themselves. Starting with the <1GHz band, TI offers solutions for SimpliciTI, 6LoWPAN, and W-MBus. Note that TI also offers SimpliciTI and 6LoWPAN in the 2.4GHz band, along with PurePath Wireless Audio, Zigbee, RF4CE, Bluetooth, Bluetooth Low Energy, ANT, and WiFi. WiFi can also operate in the 5GHz band. GPS products are receivers rather than a transmitters like all the other technologies listed. Regulatory bodies are not concerned with receiver frequency, only transmitting. Thus, although GPS technically operates in the 1.5GHz range, we’ve simply listed it here as Satellite. Note that you can also find a distinction between proprietary solutions (marked with a black box) and industry standard-based products. In the section under “Applications”, you can find a non-exhaustive list of targeted end equipment best suited for each technology, and at the bottom of the slide you can find TI’s recommended devices to lead with for each technology. You may be wondering which technologies and products fall under LPRF and which ones under ECS. Here you will see that all the technologies below lie under LPRF. This includes single mode Bluetooth low energy and ANT devices. For ECS, the following technologies are included. The overlap as you see is with the Bluetooth technologies. ECS includes dual mode Bluetooth + Bluetooth Low Energy products, and Bluetooth + ANT products. This is the only technology that has overlap between the two groups.

Having the broadest portfolio in the industry allows us to provide the broadest coverage of applications – from smart phones to smart energy. As seen in the applications section of the key slide – these are markets where we are positioned well to win. Also note that many of the end-equipments mentioned on this slide are also a focus area of our processor groups – either from ASP or WBU-OMAP side. This is not a coincidence, since a big part of our value proposition comes from combining our wireless technology with a TI embedded processor.

6. When should you use TI Wireless?
Designing a portable, battery-powered device
Designing with a TI embedded processor wanting to add wireless connectivity
Want multi-function connectivity
Need fast time to market, while avoiding heavy engineering investment
MSP430
Stellaris
Sitara
OMAP
Bluetooth
Wi-Fi +
Zigbee
Who are the customers that we are targeting? First, those customers designing a portable, battery powered device – as we already mentioned, battery-powered products is an area where we are hard to beat! Second, as I just mentioned in the previous slide, a big part of our strategy relates to winning at customers in conjunction with a TI processor or microcontroller such as MSP430, Stellaris, Sitara or OMAP. We have optimized the way our wireless devices connect to these processors, making the customer’s design effort minimal, simple, and fast. Furthermore we excel when customers are looking to include multiple wireless technologies in their device – such as Bluetooth and WiFi or WiFi and Zigbee. Lastly, we spend a great deal of time and effort trying to find ways to help customers that want to get to market fast and for less find success with our products – as we offer modules, platforms, reference designs, and partners for simpler design.

5 GHz
Highest data rate
Least crowded
Less range
<1 GHz
Now that we have a better understanding of TI’s strengths in Wireless and how we ease RF design for customers – lets take a closer look at the Frequency bands we mentioned on the key slide. What are the pros and cons of each of these bands. Often customers don’t know which band they want to operate in and this can help them narrow down their technology selection. A key advantage of the 2.4GHz band is that this frequency will work worldwide, meaning a customer can deploy their product into any market. This band has a high data rate, and also allows constant transmit otherwise known as 100% duty cycle. To put this in comparison the 5GHz band allows radars to interrupt transmission and take priority over any other trafic in the band.. The downside of the 2.4GHz band however is that it is the most crowded of the bands. This is where most consumer electronics are operating – things like microwave ovens, or cordless phones or baby monitors. This traffic can clog up the band. 5GHz is very common for enterprise applications, or mission critical devices used in hospitals or for the military. It is also starting to gain some popularity from consumer devices since it offers the highest data rate and is the least crowded of the bands – for example, Apple’s iPad has 5GHz capability. Here the downside is that the higher the frequency, the lower the range. Sub 1GHz, which includes frequencies like 433MHz or 915MHz offers the best range (lower frequency equals higher range). It is less crowded than the 2.4GHz band. On the downside, this lower frequency offers the lowest data rate.

The next differentiator on our key slide is proprietary technologies vs industry standards. This is another decision a customer will make when determining the right technology for their application. You could start by asking a customer if they plan to deploy or control both sides of the link. Proprietary solutions are good when a customer will own both sides of the signal – both the transmitting device and the receiving device. Industry standards are good when a customer wants to make sure their transmitting device is able to talk to the receiving device made from another company (or their receiver talking to another’s transmitter). The benefits of going with a proprietary solution is that the software can be tailored to the customer’s specific application and included specialized functions. The software stack will be smaller than if using a standard. The device is simpler to deploy since it only has to work with devices in its own defined network. Also a customer can select which band makes the most sense for them to operate on. The downside of proprietary is that each customer’s design will likely be different, meaning devices can’t interoperate with other suppliers’ products. Customer can design proprietary devices in the sub 1GHz and 2.4GHz bands. Also, PurePath is a TI defined proprietary solution. Unlike proprietary solutions, the key benefit of a standard is to allow devices from different suppliers to interoperate with one another. This gives the end customer the choice when it comes to choosing devices. It also makes it easy to expand your network when you want to add more nodes to your system. While standard solutions offer the advantage of vendor-independent interoperable nodes, they normally will increase each node's cost and footprint. For example, a 2.4GHz ZigBee radio node will cost approximately $2.00 (USD) and the software stack will require about 128KB of embedded memory. Conversely, proprietary sub-GHz nodes generally target low-cost systems, with each node costing approximately 30-40% less and requiring 4KB memory for the stack. Zigbee, Bluetooth, BLE, ANT, 6LoWPAN, WiFi and RF4CE are defined by industry standards.

9. Signal Strength
The strength of a signal and resulting range is an outcome of transmit (output) power and receiver sensitivity
Transmitter Power
How loud can you yell?
Higher is better
Measured in dBm (for example +10dBm)
Receiver Sensitivity
In any wireless design, the topic of range, or how far your connection (or link) can extend, will likely come up. To understand the concept of range, two parameters are important – transmitter power and receiver sensitivity. Transmitter power is best described as, how loud can you yell? Here, the louder the better, as that will help your voice travel farther. This is measured in dBm. You may see a number like +10dBm for TI-based Bluetooth system. Receiver sensitivity on the other hand, is how well can you hear, or what is the quietest sound you can detect? For this case, the lower the better. This is also represented in dBm, but since lower is better, the parameter will be negative. For example, one of TI’s Bluetooth devices has a receive sensitivity of -93dBm.
How well can you hear?
Lower is better
Measured in dBm (for example -93dBm)

11. Why Sub-1GHz Proprietary?
Allows for the longest RF transmission range, up to several kilometers (“Wide Area Networks”) depending on the Output Power
Strict RF regulations in sub1-GHz bands enable high reliability and strong RF links. Limits are typically imposed by regulatory body on:
RF spectrum output (“don’t emit in other RF channels that you aren't supposed to”)
RF duty cycle in certain frequency bands (“you can’t occupy the RF channel too long”)
Very popular in Industrial applications
Why TI Sub-1GHz?
Both best-in class RF performance and value line RF parts are available
All TI parts have fast startup and lock times. This enables lower power consumption .TI’s parts meet the most stringent ETSI, FCC and ARIB RF regulations
Extensive development kits, reference designs and application notes available
Using sub-1GHz operating frequencies in your design can provide several benefits. The most obvious one is the range. As frequency doubles the range tends to be cut by half. So using a sub-1GHz frequency compared to 2.4GHz or 5GHz allows engineers to increase its range in a very substantial way. Depending on the output power (which is a factor of an external power amplifier), it’s possible to achieve a 1 mile range. One other benefits of using sub-1GHz is the fact that the spectrum is not crowded. The extended range comes along with a bigger form factor compare to 2.4GHz. 11

12. Why W-MBus? Why TI W-MBus?
European-only wireless protocol for remote reading of heating and energy meters
Only available in 868MHz band in Europe
Allows meters to be placed where future access is difficult/not required
Allows up to 250 devices on one bus which is a benefit for apartment complexes

It allows mesh network technology, and a key benefit of 6low pan is the IP connectivity capability of every node of the network. Like in a Zigbee environment information is routed even if a node is out of order. This protocol operates in sub-1GHz frequency as well as 2.4GHz. It is very attractive for applications such as smart metering, home/industrial automation

17. Why Zigbee?
Protocol chosen as standard for SE (Smart Energy) and Medical (Continua) networks
Scalable up to 1000’s of nodes
Helps achieve full mesh topology
Allows interoperability among different manufacturers
Low data rate (up to 250Kbps) targeted for battery applications (gas /water meters)

19. Why 2.4GHz Proprietary? Why TI 2.4GHz?
2.4GHz band can be used world-wide
RF protocol can be tailored to specific application needs
Allows 100% duty cycle applications
Very low-cost designs possible with “no-cost” PCB antennas
Small form factor compared to sub-1GHz
Very popular in the consumer segment
Why TI 2.4GHz?
TI has both transceiver, transmitter and system-on-chip RF parts with embedded microcontroller and USB
Excellent co-existence performance in noisy environments
Extensive development kits, reference designs and application notes available
TI offers free of charge SimpliciTI protocol for a fast and easy start to build networks”
The 2.4GHz band can be used world wide. When used in a proprietary system, it allows the engineer to tailor it to a specific application needs (Software overhead, current consumption etc…). It is important to note that products operating in the 2.4GHz band offer small form factor compare to the one operating in the sub-1GHz. The smaller form factor is explained by the shorter wave length. However 2.4GHz products needs special care to be able to operate without being jammed, as the 2.4GHz is a very saturated one with several systems such as Bluetooth, Microwave ovens and others systems operating in this band.
One advantage TI offers in the 2.4GHz is our Co-existence performance in noisy environments compared to competition. 19

20. Why PurePath Wireless? Why TI PurePath?
Wireless audio solutions tailored for headphones, headsets, speakers and home entertainment systems
Designed for wireless audio, no dropouts
Uncompressed, low latency CD-quality audio streaming enabled by 5Mbps RF data rate

21. Why Bluetooth®? Why TI Bluetooth?
Wireless data, audio or voice in industrial, consumer and medical applications
Replacement of serial cables
10-100m range personal ‘bubble’ (Personal Area Network)
Instant, secure, automatic connections
Low power consumption
(AAA battery power source)
Good data rates (~2Mbps throughput)
Install base of 3 billion units
Why TI Bluetooth?
Best in-class RF performance (Transmit and Receive)
Dual-mode options with ANT & Bluetooth
Available with Wi-Fi
Highly integrated, fully certified module available to reduce cost and time to market
When and why would it make sense to use Bluetooth?
First and foremost, Bluetooth allows you to replace traditional serial cables in order to send data, audio, or voice wirelessly. It is designed to operate a short range, typically 10 meters, which is about a room’s length. You can think of this range as a personal bubble or Personal Area Network. In some systems, Bluetooth can even range up to 100m.
Bluetooth connections are instant and automatic, but also have a high level of security.
Bluetooth is well suited towards applications that require low power, such as those running off a battery like a triple A. Bluetooth also has good data rates, in the range of 2Mbps throughput. Later in the presentation, I will compare this to other wireless technologies.
What makes TI’s Bluetooth solution unique? TI’s solution offers best in class RF performance, both for transmit and receive. This year we announced the CC2567 which is the first device to market and currently the only device offering ANT & Bluetooth in a single chip. We also have combo solutions available with WiFi which greatly eases customer’s multi-technology designs. Lastly, fully integrated and certified modules are available which greatly speeds a customer’s time to market while keeping engineering investment low.

22. Bluetooth Operation Devices form ad-hoc networks called piconets
Each piconet uses a different frequency hopping sequence
Piconets have 1 master and up to 7 slaves
Master determines hopping scheme and timing
Communicate in round-robin fashion
Devices can switch roles
Frequency (GHz)
Designed to avoid interference
Hop between 79 frequencies of 1MHz each ( GHz)
Pseudo-random pattern known to transmitter and receiver
Let’s now discuss how Bluetooth actually works. Bluetooth technology resides on the 2.4GHz unlicensed ISM band. ISM stands for Industrial, Scientific, and Medical, and was designed to allow products like microwaves, baby monitors, and cordless phones, to operate without requiring the user to have a license to use these devices. To be clear, unlicensed does not mean unregulated. We will discuss required regulations further in the presentation. As you can imagine, the 2.4GHz ISM band can get very crowded with several devices in a home using the same frequency band, in addition to Bluetooth, Zigbee and WiFi- enabled products.
In order to allow all of these devices to operate without interference, Bluetooth utilizes a method called frequency hopping spread spectrum. I mentioned Bluetooth sits on the 2.4GHz band, but to be more specific it resides between frequencies to As shown in the graph on the right, the signal will hop between this range of 79 frequencies, 1MHz each in order to avoid colliding with other signals. The signal is also able to recognize which frequencies may be trouble spots, and learn to avoid those spots. The hopping is carried out in a pseudo-random pattern which is known to both the transmitter and receiver.

23. Why ANT?
Ultra low power (ULP) enables coin cell operation for wireless sensors with battery lifetime of 1 year and longer
Main market in sports and fitness sensors, medical and healthcare devices
ANT is a proprietary protocol developed by Dynastream that operates in the 2.4-GHz ISM band
ANT+ defines a set of device profiles to ensure products from different manufacturers are interoperable; Established ANT+ ecosystem of over 14 million devices
Why TI ANT?
Only TI offers single-mode (CC2570/71) and dual-mode solutions (CC2567, WiLink)
Fully tested TI ANT ecosystem solution – for both sensor and mobile handheld devices
Best in class RF performance
Excellent coexistence with other 2.4GHz devices
ANT technology has been created by a company called Dynastream that brings ultra low power wireless to sensor applications. These sensors can operate off of a coin cell battery for more than a year without recharging. This is really beneficial to things like sports and fitness sensors as well as medical and healthcare devices. As seen here for example, he can use sensors to monitor his bike stats like cadence or speed, as well as his heart rate. ANT has been deployed in over 13 million low power devices. TI is unique in the ANT market in that we’re the first in the industry, and only supplier with Bluetooth and ANT in a single device. We also offer ANT only devices – so that we can be at both the sensor and the aggregator – for example a cell phone collecting all the sensor data. This is coupled with our best in class RF performance and coexistence.

24. ANT Applications
These are a subset of ANT profiles

25. Why Bluetooth Low Energy (BLE)?
Ultra low power consumption, similar to ANT battery lifetime of 1 year and longer
Fraction of the power of Bluetooth enabling non-rechargeable batteries (alkaline or coin cell) while addressing Bluetooth installed base through dual-mode chipsets
Target applications are consumer medical, sports and wellness, and mobile accessories
Why TI BLE?
TI provides both single mode and dual mode Bluetooth low energy solutions
Both sides of the link to create a fully tested Bluetooth low energy ecosystem - from smart sensors to smart phones
Leading RF performance up to -97dBm
Excellent coexistence with other 2.4GHz devices
CC2540 System on a chip integrated solution (host & controller) and certified modules available
Bluetooth low energy, or BLE is also enabling coin cell operation for wireless sensors, with operation over one year. BLE is Bluetooth technology with lower power consumption. Like ANT, BLE is well suited for health, medical, sports, fitness, and mobile accessory applications. TI provides both Bluetooth + BLE devices in a single chip as well as BLE only, with best in class RF performance and coexistence.

26. Why Wi-Fi?
Connect electronic devices to each other, to the Internet, and to wired networks – quickly and securely
Most prominent wireless connectivity technology for computers and internet
Real-world performance similar to wired networks
High data rates (>20Mbps throughput)
Over 2.5B Wi-Fi units deployed in the market today; ~1 billion units/year projected starting in 2011
Why TI Wi-Fi?
Best in class idle-connect current 0.72mA for deeply embedded applications
Single Antenna & on-chip coexistence when using the integrated Bluetooth
Highly integrated, fully certified modules available to reduce cost and time to market
Platforms offered that integrate system hardware and software
When and why would it make sense to use WiFi?
First and foremost, WiFi allows you to connect devices to each other, to the Internet and to wired networks, all in a fast and secure way. WiFi is the most widely used method of connecting computers to the Internet. WiFi can be considered as wireless Ethernet, as you get very similar performance as you would if you were using a wired connection like Ethernet. A key value of WiFi is the high data rates you can achieve, above 20Mbps for real-world applications. In a moment we’ll take a look at how that compares to other wireless technologies. WiFi has become increasingly popular and widespread, with over 2.5 billion units in the market, and 1 billion units to release in 2011 alone. In an interesting survey, 9 out of 10 Americans surveyed in a consumer poll said they would rather do without Starbucks for a year than give up their Wi-Fi connection!
Key highlights of TI’s WiFi solution is that it combines Bluetooth with best-in-class coexistence. As we mentioned at the beginning, TI excels in low power- we’ve optimized the device so that even high data rate WiFi, along with Bluetooth, can operate off of battery power. As with Bluetooth we offer integrated and certified modules, along with platforms that integrate system hardware and software for a host processor and radio. Note also that TI has more than 50% market share for WiFi in mobile handset – which speaks to the advantages our solution brings to mobile handheld products.

27. WLAN Infrastructure Mode Networks
Access Point (AP)
Networks are built to transfer data between stations
The hub to relay all network communications, translating frames between a wireless medium and a wired medium
Given a service set identifier (SSID), which becomes the network name for the users
Sends out beacons to let stations know there is an access point they can connect to
Stations
Computing devices with wireless network interfaces
Stations associate with an AP to join a network
Stations listen for beacons to understand if any traffic is available
Because stations know when the next beacon is coming, they can go to sleep during this wait period and wake up in time for the next beacon
Stations can access the Internet through the access point connected to a network
Access Point
Lets shift now to network configurations. The most common type of WLAN network is the WLAN Infrastructure mode network. This consists of an access point and stations. Stations are Wi-Fi enabled devices like tablets, laptops, or smartphones, just to name a few examples. Networks are created in order to allow stations to communicate with each other or connect to the Internet. Access points serve as the main hub in a network that routes all communications and translates between wired and wireless. In order to identify an access point, it is given a service set identifier - or SSID. This becomes the network name that all stations will use. An access point will send out a signal called a beacon that alerts stations that there is an access point that they may connect to. A station must first associate with an access point to join the network, and then it will listen for beacons to see if any traffic is available. The stations know at what interval the beacons will arrive – so they can save system power by going to sleep in between these beacons, and wake up in time for the next one.
Stations

28. Why GPS?
Space-based global navigation satellite system utilizing a constellation of 27 Earth-orbiting satellites
Provide reliable location, time, and velocity information to a receiver anywhere in the world
Widely deployed and useful tool for asset tracking, industrial automation, surveillance, banking, power grids
Why TI GPS?

Highly integrated, fully certified modules available to reduce cost and time to market
GPS is unique from the other technologies we discussed in that it is a space-based satellite system used to provide not only location, but also highly accurate timing and velocity data. Several application areas are emerging outside of the traditional personal navigation devices. GPS is being used in commerce for asset tracking, in security surveillance, in banking, broadcasting, and power grids for accurate timing applications. New areas like geo-tagging a camera image, child safety, and social networking are becoming increasingly popular.
With its upcoming product release, TI will allow customers to connect their GPS chipset to their host simply, quickly and easily. TI also provides aGPS which allows a quick startup time also known as Time to First Fix – meaning that it can more quickly determine its location, time, and velocity. As with WiFi and Bluetooth we discussed, integrated modules are also available – again speeding up customer development time and easing the expertise required.

Now that we have an introduction to each of TI’s wireless technologies, lets see how they compare to one another. There are three benchmarks a customer is likely looking for when determining the right wireless technology for their application. These are range, data rate or throughput, and power consumption. In this graph, we represent the Range of each technology. You can see that technologies like Bluetooth, Blueooth low energy and ANT are closer to 10 meters, which is about a room’s range. Zigbee, RF4CE, WiFi and 2.4GHz Proprietary have a typical range of 100m, which in a real-world situation, equals about the range of a house. The range of these technologies can be increased by adding a power amplifier. Sub 1GHz can achieve the furthest range around 10km or 6 miles. Note that a big factor in range will be whether a power amplifier is used with the radio. Regarding data rate–WiFi is the fastest with more than 20Mbps throughput possible using n. Bluetooth throughput is around 1.5Mbps, while the remainder of the technologies are limited to 1Mbps or less. What kind of power consumption are we looking at for each of these technologies? If we look at it terms of the power source required, BLE/ANT, Sub 1Ghz, and 2.4GHz Proprietary draw the least amount of power and can thus operate off of a small coin cell battery. Bluetooth, Zigbee and RF4CE would need a little more power, about the level of a AAA battery. While WiFi has the highest power consumption (which makes sense considering it has the highest data rate), it can still be battery powered, in this case by a li-ion.
