“How can I improve

communications and extend

resources?”

“How do I further my civic

agenda?”

“How can I demonstrate effective

leadership and communicate with

my constituents while keeping

costs low?”

“How can I maximize my

workforce and demonstrate

effective leadership?”

“How do I deliver my mandate as

quickly and efficiently as possible?”

“I want my voice to be heard,

What is Bluetooth Low Energy? Bluetooth Low Energy (BLE) is a subset of the Bluetooth 4.0 spec

- Ultra-low power consumption – run for years on a coin battery

- Low-cost system-on-chip solutions – proliferate in small devices

- Simplified communication protocol – easy to implement & extend

Operates on the 2.4GHz ISM band (2400-2483.5MHz)

- 40 channels in-between & overlapping WiFi Ch 1,6,11

- 1Mbps GFSK, frequency-hopping

- Reliable signalling up to 100m

Devices identify themselves with UUIDs

- Like a MAC address, but also encodes a “profile”

- Sensors, health monitors, alarms, etc.

Assortment of RF Beacon vendors;

both proprietary & iBeacon



Once you have deployed your BLE tags, you need to configure and maintain them…

Where did you get your tags from?

Hundreds of tag makers today (Accent systems, trubeacon, miipharos, sticknfind, lassotag, Aircable, bluecats, BlueSense, Estimote, Footmarks, Gelo…)

BLE Management Challenges Replacement? Batteries? Lost? Stolen? Rogue Tags?

Which batteries need to be

replaced?

Has a tag been stolen?

Need to update info on all tags

in cafeteria…

How do I find Rogue Tags?

Multi-User MIMO (MU-MIMO) How does it work? Why is it an advantage?

17

Clients are able to benefit in the downstream link for higher aggregate throughput by essentially “tuning out”

(nulling) portions of the RF to better decode their traffic.

Antenna Selection: Decide which antenna is right for the job.

Antenna Placement: Where will this antenna provide the best throughput and most reliable service?

Consider:

• Line of sight

• Isolation from ambient RF

• Angle of incidence to client devices

Consider:

• Density of clients to be served

• Available mounting assets

• Within ~20m of furthest client

Maximize the Spectrum Avoid Excessive Management Traffic

45

Always aim for 1 SSID – Especially in dense areas

More SSID’s = Worse Performance

Why? – Each SSID requires a separate Beacon

– Each SSID will beacon at the minimum mandatory data rate

Each broadcast SSID will respond to null probe requests – Exponential amounts of airtime wasted

For Your Reference


Probe Requests & Responses

Often #1 frame types observed in HD packet captures

Especially in smaller enclosed venues

Why? – Venue is packed with omni-antenna

equipped smartphones probing at 1mbps

– Result: we hear probe requests from client devices far outside our own cell

46

For Your Reference


Maximize the Spectrum PHY Rate Tuning: Why PHY Rates Matter

47

How fast can we talk?

–Signal (RSSI) and Noise are key factors

As client moves further from AP or as noise worsens, client rate-shifts downward

Lower rate, more airtime consumed

Position AP’s and antennas to allow elimination of low rates (i.e., <18mbps)

Eliminate 802.11b rates
