3 Agenda- next 50 minutes Quick snapshot of wireless in enterprise space- and where we are going Technologies explored: -WIFI Bluetooth -ZigBee NFC -NFC licensed spectrum (cell) -public safety other, other Drivers for tomorrow: IoT and other

4 What I WON T say today insatiable demand for bandwidth OR ubiquitous wireless OR continued massive growth in the number of devices all connected by parallel

5 What I will focus on in the next 49 minutes What I care about as designer/ engineer What I care about as an installer What I care about as I give advice What is truth versus hype What is the real world BICSI environment

6 What are the facts? *90% of the world s population over age 6 will have mobile by 2020 (7.2 of 8 billion people) *It takes, on average, 13 years to reallocate and deploy spectrum for wireless systems *Global mobile data growing by 61% CAGR per year *Estimates of IoT (internet of things) speak to 50 billion connected devices by 2020

7 What we need to consider for wireless How far does it go (range)? How well does it transmit (propagation characteristics)? How much does it cost? How much data? How much power does it consume? Licensed or unlicensed spectrum? How complex?

8 Signal propagation ranges Transmission range communication possible low error rate Detection range detection of the signal possible no communication possible Interference range signal may not be detected signal adds to the background noise sender transmission detection interference distance CS

$Receiving power additionally influenced by fading (frequency dependent) shadowing reflection at large obstacles refraction depending on the density of a medium scattering at small obstacles$

9 Signal propagation Propagation in free space always like light (straight line) Receiving power proportional to 1/d² in vacuum much more in real environments (d = distance between sender and receiver) Receiving power additionally influenced by fading (frequency dependent) shadowing reflection at large obstacles refraction depending on the density of a medium scattering at small obstacles diffraction at edges refraction shadowing reflection scattering diffraction CS

10 Multipath propagation Signal can take many different paths to reflection, scattering, diffraction between sender and receiver due LOS pulses multipath pulses signal at sender signal at receiver Time dispersion: signal is dispersed over time Îinterference with neighbor symbols, Inter Symbol Interference (ISI) The signal reaches a receiver directly and phase shifted Îdistorted signal depending on the phases of the different parts CS

11 Range and loss Cellular Wi Fi Free space path loss: exponent of 2 Terrestrial path loss: exponent of 3+ Even with exponent of 2: Wi Fi. 100m to 200m: signal at 25% strength Cell. 1.0km to 1.1 km: signal at 83% strength Difficult to propagate short range network (Wi Fi) signal) Distance

12 IEEE PAN- personal area networks ZigBee Zwave WirelessHART WiSUN Low power, low speed, low cost

13 ZigBee Short distances ( meters), low power Suitable for devices like power meter, light switch- low data, lower cost and complexity than other technologies

15 Bluetooth Ericcson, to 2483 MHz Short range, low power Packet based, and master-slave structure Version 4.2 slated for IoT-

17 NFC(near field communication) Designed for phones and other devices to establish link, 10 cm or less Unlicensed MHz spectrum Used in conjunction with RFID chips

19 Implications for buildings (low) These do not relay on infrastructureinstead, device to device communication Be aware of their limitations Be aware of the problems they solve for clients

20 ALOHA Net: 1971 WaveLAN: 1991, joint effort IBM+NCR, for cash registers protocol: 1997, 2 meg Pervasive, ubiquitous, familiar

21 802.11a b n 2009, intro of MIMO ac 5 GHz

22 802.11ad GHz (V band) 1-7 Gbps meter range Beamforming

23 From 4 billion today to 7 billion by 2018 One hot spot for every 20 people From secondary to primary for enterprise office

24 Wi Fi Calling Wi Fi in M2M Wi Fi over Power (WiPO)

25 Implications for buildings (high) ISO/IEC TR TIA TSB-162-A Honeycomb grid, each cell covers 12M radius Square grid, each square 18 meters wide

26 Implications for buildings (high) -most recommend Cat-6A (multiple drops per WAP) for Wi Fi today -more WAPs and closer to the user mean more infrastructure, more space, more pathway -are clients reducing 6A drops in office and giving them to Wi Fi?

27 Spectrum licensed for public use

28 What will 5G look like? A cellular system that supports: 1000 times higher mobile volume per area 10 to 100 times the number of connected devices 10 to 100 times higher typical user data rate 10 times longer battery life 5 times reduced end-to-end latency

29 How will we get there and what does it mean to designers and installers? LTE- what does this term mean? Spectrum for 5G- what is millimeter wave technology?

30 LTE: long term evolution LTE is quickly becoming global standard for next step beyond 4G LTE benefits users with greater capabilities

31 Existing Cell Bands LTE for extended period Eventually 5G radio 3 GHz 10 GHz New 5G Bands Wide radion bands 5G radio methods Core 5G Network integrates Existing LTE in Cell Bands with 5G Radio in New Bands 300 GHz Courtesy Rysavy Research

32 Where are characteristics of 5G?

33 Millimeter wave technology 60 GHz and 70/80 GHz Subject to rain fade High data rate (Gbps or fiber like speeds) Short range

34 FCC direction on 5G in US US has decided on proposing the following ranges to be studied: to 29.5 GHz to 40.5 GHz to 50.2 GHz to 52.6 GHz to 71.0 GHz

35 Massive MIMO More antennas- up to hundreds of antennas at base station Possibly 5x the spectral efficiency

36 What the heck is beamforming?

37 Beamforming, or spatial filtering Technique used for directional signal transmission Combination of elements in a phased array in such a way that signals at particular angles experience constructive interference and others experience destructive interference Can be at both transmit and receive Used to improve gain over omnidirectional

38 What about public safety wireless? New building codes (IBC) that mandate in-building wireless coverage drive DAS in most significant buildings Building designers must design, or at least accommodate these systems 38

City of Marlborough FIRE DEPARTMENT 215 MAPLE STREET MARLBOROUGH MASSACHUSETTS Emergency communications have been proven to be the lifeline for firefighters, police officers and EMS personnel inside

39 City of Marlborough FIRE DEPARTMENT 215 MAPLE STREET MARLBOROUGH MASSACHUSETTS Emergency communications have been proven to be the lifeline for firefighters, police officers and EMS personnel inside of large structures. Research and investigations into Line of Duty Deaths (LODDs) and injuries to Fire, Police and EMS personnel show that the loss of reliable communications inside of such buildings is a contributing factor in death and injuries to emergency personnel.

40 What will the public safety network look like tomorrow? New, federal government public safety 700/800 MHz network ($7 billion) the law gives FirstNet the mission to build, operate and maintain the first high-speed, nationwide wireless broadband network dedicated to public safety. FirstNet will provide a single interoperable platform for emergency and daily public safety communications.

41 What will the public safety network look like tomorrow? Get a shared operational view of an incident with high quality, streaming video, hardwareaccelerated graphics and ultrabright display that you can view in direct sunlight (Motorola Solutions) FUTURE enhancements: Multi-media Location data Mobile video Content acceleration and management

42 Implications for buildings (high) -people want to use their 5G device in the building where they work -we continue to be very aggressive with building energy policy (block RF) -we are moving from 50 ohm coax to Cat- 6A as transport for in-building wireless/ DAS

43 Internet How big is IoT? Things

45 Drivers for tomorrow -sensors -apps -their economic and human impacts

46 Sensors --economic factors drive deployment and use -value of transaction + low cost of sensor= widespread use -sense light, energy, movement (accelerometers), biomedical functions of user, temp, environment, etc. -sensors connected wirelessly (always) to other devices and the network

47 Sensor example 1 -UBI: Usage Based Insurance- sensors on vehicle report when and where and how fast and how safe -potentially massive economic impact

48 Sensor example 2 -wearable sensors in hazardous environment: workers in chemical plant or refinery equipped with canary in cage to measure toxic gas, temps, and activity and movement of worker -potentially massive life impact -large economic impact (reduced premiums?)

49 Sensor example 3 -SCADA: supervisory control and data acquisition- utilities embed sensors in infrastructure- continuous control and knowledge- without a truck roll or human operator -massive economic impact 49
