Superior In Environments with RF Interference

Automotive study on impact of Bluetooth and WiFi interference on ZigBee and Bluetooth low-energy signals.

Communication channels between parts of the car (e.g., from engine to cabin) were compared while the car was parked (parking lot) and in

motion (driving).

Lin, Jiun-Ren, Timothy Talty, and Ozan K. Tonguz. "An empirical performance study of intra-vehicular wireless sensor networks

under Wi-Fi and Bluetooth interference." 2013 IEEE Global Communications Conference (GLOBECOM). IEEE, 2013.

Y-axis is impact on “goodput” (amount of good data received) performance. Smaller is better.

Bluetooth, with its greater flexibility in channel selection, outperformed ZigBee in most conditions.

Example

10

Superior over Sub GHz Solutions

• Higher bandwidth for greater throughput and lower power

– Increased throughput decreases channel occupancy time, decreasing

collisions and interference, increasing “goodput” and decreasing transmit

power requirements (since standby power << xmit power)

• Less than half the antenna size reduces BOM and often product size

– Antenna size inversely proportional to wavelength

– Wavelength (WL) = Wave Speed / Frequency

• Range limitations offset by high performance capability

– Laws of physics dictate that for a given output power, the sub-GHz

frequencies provide longer range, BUT…

A Deeper Dive on the Bluetooth Radio

17

Understanding Transmission Differences

• 2400 – 2483.5 MHz: globally regulated and license free

– For non-telecom industrial, scientific, and medical (ISM) communication

– Shared by various protocols. Examples: 802.11 (b,g,n), classic Bluetooth, Bluetooth LE, and ZigBee

• Regulators limit RF transmit power for everything on this band to common ERP and EIRP levels

– Effective Radiated Power (ERP) and Equivalent Isotropically Radiated Power (EIRP)

– At the regulated limits (ie, 20 dBm or 100mW), the power transmission is concentrated in Bluetooth over a narrow frequency (2MHz)

– In 802.11, that same power limit is dispersed over a wider frequency (20-40MHz)

– Therefore Bluetooth goes farther (and thru more obstacles) than 802.11 b,g,n even at same regulated power level

Bluetooth Provides Better Support in Congested Networks

• Bluetooth frequency hopping allows it to avoid congestion

– Bluetooth hops between 37 channels when sending data

– Pseudo-random hopping limits collisions even with many Bluetooth devices on network

– Identifies congestion (eg, from 802.11) and avoids those frequencies (ie, Bluetooth plays nicely with 802.11)

• Also uses different modulation scheme, further reducing conflict

• 802.11 becomes slower and less reliable with more devices

– Effectively, only three mutually non-interfering channels available for all 802.11b,g,n traffic; 1 channel for 802.11n (within 2.4GHz range)

– With congestion, an exponentially increasing “backoff” time is used between transmission

– With more collisions, backoff increases, and Wi-Fi becomes slower and less reliable

2.4GHz WiFi Facing Increasing Congestion

“Today, [WiFi] congestion has gotten so bad in many regions that it has pretty much made the 2.4-GHz band unusable ….

… almost all smartphone makers, including Apple, no longer recommend using [WiFi on] their smartphones at 2.4 GHz.”

21

Bluetooth Has More Channels for More Traffic

• While both support 2MHz channels, Zigbee has fewer channels (16) vs Bluetooth (40) Increases contention with more devices

• 75% (12 of 16) of the Zigbee channels overlap with 802.11b/g networks

– Of the four non-interfering Zigbee channels, one operates at 2455MHz, where microwave ovens operate

– Bluetooth has 9 available channels in 802.11b/g environment vs Zigbee’s 4 channels

ZigBee Inability to Frequency Hop Impacts Reliability

• Once it finds a channel, ZigBee stays with that channel. Bad for ZigBee traffic.

– ZigBee will search (“ZigBee Frequency Agility”) for a clean frequency / channel and park itself there. Forever.

• Unlike Bluetooth, ZigBee has no mechanism to automatically change (“hop”) channels

– If congestion increases, ZigBee stays on the crowded channel

– If another radio (eg, 802.11) creates interference on that same frequency, ZigBee stays on the poor channel

– Crowded channels, poor channels ZigBee messages get delayed (if congestion) or are never sent (if interference)

• If ZigBee is using a channel that 802.11 wants, ZigBee won’t (can’t!) make room for it. Bad for WiFi traffic.

– ZigBee doesn’t change channels. The 802.11 radio must wait until ZigBee gives up the channel… if it ever does

ZigBee Impact on 802.11 Networks

• ZigBee can cause other problems with 802.11b/g networks

– If ZigBee doesn’t hear 802.11 transmission, ZigBee transmits

– Since 802.11 has lower peak TX power than ZigBee, 802.11 transmission may not be identified by ZigBee even though it’s there

– Conversely, 802.11 radio may detect ZigBee (but not vice versa), forcing the 802.11 radio to stop transmitting

• Requires careful planning and positioning of radios

– Bluetooth transmits more quickly, making it easier for 802.11 to recover

Bluetooth Frequency Hopping• What is Frequency Hopping

– Leverage all 37 2MHz Bluetooth data channels across the full 83.5MHz of available spectrum

– Identify good/bad channels based on signal strength (RSSI) or packet error rate (PER) or other methods

– Change frequency channels 1600x per second

• Limits time on bad channels

• Limits interference and impact on other communication protocols (0.625ms of interference)

– Send on good channels, avoid bad channels

– Pseudo-random hopping sequence limits ability for interception of complete message

• Benefits of Frequency Hopping (1)

– Decreases narrowband interference

– Can share a frequency band with many types of conventional transmissions with minimal interference

– Avoids interference and multi path fading (distortion)

– Increases signal capacity

– Improves the signal to noise ratio

– Efficiency of bandwidth is high

– Improves privacy

– Difficult to intercept this transmission

• Similar technique used in some military applications to avoid jamming (2)

(2) https://en.wikipedia.org/wiki/Frequency-hopping_spread_spectrum

26

Bluetooth Adaptive Frequency Hopping Learns and Avoids 802.11 Channels

• Signals are sent out on all 37 data channels (frequencies 2402 to 2480 MHz)

• Channels are changed pseudo-randomly over time

• As noise and interference is detected on channels, Bluetooth avoids these frequencies

– Right image

27

Bluetooth Radio (PHY) Strengths over Other 2.4 GHz Protocols

• Superior congestion management through frequency hopping

• Superior interference management through frequency hopping

• Superior transmit distance vs 802.11 networks

• Superior co-existence with 802.11 environments

LE Advertising Extensions

• Reduce the amount of duplicate advertising

– Host only gets the advertising reports of interest

• Filter advertisements for specific advertising data

– Discovery procedure with the purpose of finding specific service providers

– Example: find all Time servers

• Low duty-cycle directed advertising

– Add low-duty variant of directed advertising to the LE standard

• Extended scan response

– Scan Response packet increases 7x

• This allows scan response to occur without setting up a complete connection.

• Result: Lower power

33

Slot Availability Mask (SAM)

• Allows two Bluetooth devices to indicate to each other the availability of their time slots for

transmission and reception

• Benefits internal networks topology management

• Benefits external networks co-existence with mobile wireless services

34

High Duty Cycle Non-Connectable Advertising

• Non-connectable advertising can use Advertising Interval <100ms for limited periods of

time

– Current minimum is 100ms

– Improved user experience

– Improved battery life through faster connection
