Communications

System Overview • Wi. Fi Communications - Connectivity is highest priority - Critical to get Gas detector data back to Location Manager server - Can still get a rough location based on which Access Point the device is using for communicating w Typical “operators” have a very detailed knowledge of activities in a unit and the “permitting process” provides additional information - System provide a “bounding box” for the estimated location - Devices have sufficient internal storage to buffer up to 8 hours worth of data for operation in areas with little or no coverage w Data availability is still faster than waiting for a device to be “docked” • Requires an IEEE 802. 11 b/g network for the Gas detectors to communicate back to the Location Manager • Location Anchors do not provide any communications services and are for improving the location resolution 18 HONEYWELL - CONFIDENTIAL

Location Reference • Location is independent of Communication • The number of Location Anchors is determined by the Location Resolution and there is no relationship to the number of access points - Using Access Points for location reference can reduce the number of Location Anchors required • Devices will collect RSSI information from any reference that has an SSID matching the VLAN or the Location Anchors • The actual location estimate is done by the Location Engine component in the Location Manager server and not by the device 20 HONEYWELL - CONFIDENTIAL

Detailed Communications requirements • IEEE 802. 11 b/g WLAN network, IEEE 802 wired or 802. 11 -g to Location Manager Server/Clients. Maximum of 1 second network latency. • Single SSID (preferably a dedicated VLAN with a unique SSID). The VLAN must span the networks without client device IP address updates. The SSID can be either broadcast or hidden. • Separate SSID for Location Anchors communications (Loca. Xion_Anchor) • At least -72 d. Bm at all locations where the wireless devices will be used. • Access points to be used for location must be 30' (10 m) above the grade and have a known, fixed transmit power level between 10 d. Bm and 26 d. Bm +/- 2 d. Bm conducted into the antenna. The antenna should provide 5 -6 d. Bi gain and have a nominally omnidirectional transmit antenna pattern. Gain values for the antenna should include all losses through cabling, connectors or other devices such as lightening arrestors etc. • Access Point transmit beam-steering or beam-forming must be disabled for all Access Point MAC addresses that will be used by the Location Manager for location. Use of transmit beam-forming for other VLANs whose MAC addresses are not configured in the Location Manager is acceptable. Use of receive path beam forming to improve reverse link reliability from client devices on the Safety. Ne. X VLAN is also acceptable. • All access points within the WLAN network must have a unique, known radio MAC addresses on the VLAN that will be used by Safety. Ne. X • WLAN signal repeaters and range extending devices are not usable for location. 25 HONEYWELL - CONFIDENTIAL

Detailed Communications requirements • The IEEE 802. 11 b/g WLAN network security will be WPA 2 with PSK and AES encryption. Note: WPA-Enterprise security and authentication (e. g. RADIUS server) is not currently supported by Safety. Ne. X client devices. • Static IPs and/or DHCP for the devices (Management of static IP addresses and/or a DHCP server is a customer responsibility). The DHCP server must be able to respond within 1 second. • The LM server and clients use static IPs. • Any routing or firewalling within the network must be configured to allow bidirectional UDP/IP communications between devices and LM server. • The default configuration for the LM and the devices is UDP communication over port numbers 50009 & 50010. These port numbers can be updated to different ports on LM and the devices (devices are configured using Fleet Manager). LM Server & Client communication use TCP & FTP communications with default port numbers are 5000 & 5001. These port numbers can be updated to different numbers in the Client and server. It is the responsibility of the Customer/Integrator to configure the system so that the ports are open and available for the Safety. Ne. X communications. • Connection of the OPC server to Experion or other systems will be via the Tunneller. It is the responsibility of the Customer/Integrator to configure the network for communications between the Tunneller and the other systems or applications. 26 HONEYWELL - CONFIDENTIAL

Location Theory and Practice

Key Requirements • Location Methodology - RSSI based multi-lateration location using RSSI information from the existing Wi. Fi network Access Points (APs) and optional Location Anchors for lower cost - Works in areas of heavy structure where most other location technologies have reduced or no location capability. “Accuracy” needs to be achievable in a refinery process unit - The system objective for the RSSI based location is to achieve accuracy down to 10 m (site or area wide average, at 50% CEP) using a combination of APs and LAs with an average spacing of 2 times the desired location accuracy and a relatively uniform distribution across the "area of interest“ such that at least 3 APs/LAs are in range of the gas detectors. - Support optional GPS location for open areas like tank farms (higher accuracy if good GPS satellite visibility) 28 HONEYWELL - CONFIDENTIAL

Loca. Xion Anchor – Wi. Fi Beacon Device • Provides additional location reference information for better resolution • Does not provide any communication functionality • Responds to “probes” to produce an RSSI reading like an AP • Improves location resolution at a lower cost than Access Point • Network access not required • Physically smaller • Lower cost • Low powered • Temporary use for maintaince and turn around 29 Cost Effective Location Enhancer HONEYWELL - CONFIDENTIAL

RF Location Technology Approaches • Portable RF location products generally determine location by measuring distance from 3 or more known locations (multi-lateration) • Distance can be measured by: 1. Signal Strength – strength of RF signal degrades over distance traveled, measure signal degradation to calculate distance. (Honeywell, Ekahau, Aero. Scout, Cisco) AND/OR 2. Time of Flight – measure time RF signal takes to go from transmitter to receiver. Measure round trip time or use precisely synchronized anchors to measure difference in arrival time (Zebra, Purelink, Time. Domain, GPS) 30 HONEYWELL - CONFIDENTIAL

Bm) Use the fact that the strength of an RF signal degrades over distance traveled and measure signal degradation to calculate distance. -30 -40 -50 -60 -70 -80 -90 Distance (m) Signal Strength measurement capability existing in RF devices can be used without additional hardware 31 HONEYWELL - CONFIDENTIAL 60

Weighted RSSI Multi-lateration (Honeywell Approach) • Signal strength is only an approximate measure of the distance. • Even though the exact mapping of signal strength as a function of distance cannot be found an upper bound (and uncertainty) can be established. • The uncertainty in the distance measure is inversely proportional to the signal strength received: Distance uncertainty - The louder you hear some one the more - confident you are of their distance estimate. The farther away you are, the less certain is your estimated distance from them • Honeywell approach takes the upper bound and the signal strength into account while calculating the position. - More weight is placed on distance measures - derived from stronger RSSI signals The Position estimation is confined within a bounding box derived from the overlapping set of all upper bounds. Robust algorithms for maximum accuracy under uncertainty 32 HONEYWELL - CONFIDENTIAL

Why Honeywell RSSI Technology? • No additional Infrastructure required (Time of Flight solutions require additional infrastructure e. g. GPS chips, satellites, UWB receivers, special Access Points) • Works both indoors and out (GPS does not work indoors or with obstructed view of sky) • Does not require extensive site surveys (unlike RSSI fingerprinting) • Client-based RSSI collection allows communication back to the device TOF and AP-based RSSI solutions cannot communicate back to the device. Not all APs can be used in AP-based RSSI collection • Scalable accuracy with low cost beaconing anchors ( TOF methods suffer with high anchor density; AP-based RSSI and TOF methods require much higher cost to scale) • Better algorithm – Weighted, Constrained Multi-lateration. An estimated position and a bounding box representing error in estimate are generated. (multi-lateration methods that do not use weights and/or bounding boxes and fingerprinting methods cannot produce bounding boxes of the estimated uncertainty) • Location accuracy topology mapping for cost optimized installation • Real-time position error estimation and monitoring Honeywell provides best value with a low cost , scalable accuracy solution 33 HONEYWELL - CONFIDENTIAL

3 Classes of Variation: - What can be controlled Best by RF Planning/System Design: w w w w AP and Location Anchor Density (improves overall site performance, but high cost to scale) Local improvements (addition or relocation of anchors to solve a specific cold spot) Correct AP and LA Transmit power and mapping location datafill in Location Engine Uniform AP & LA Antenna Heights (reduces ‘pull’ from far reaching AP’s or Anchors) Accounting for structure (mitigated by site visit / RF survey work ahead of site RF design) Controlling RF Configuration Settings (e. g.
