1 Bradband Summit OPERATIONAL ISSUES AND CONCERNS WITH BROADBAND DATA Michael Weins Directr, RCC PSIS May 6, 2014

2 RCC Cnsultants Wrking with public safety and mbile data systems fr ver 30 years RCC has develped tls t design and analyze mbile data/lte systems with cnsideratin fr peratinal criteria including cverage, capacity, security, cst, number f users, and system management and cntrl.

3 Chke Pints infrmatin frm public t PSAP (ESINet capacity) PSAP t first respnder (Public Safety Bradband Netwrk) Human Intel Capacity (hw much data can an individual prcess?)

4 Data Surces

5 Capacity Issues Drive Functinal Capabilities Histrically, lw bandwidth limits applicatins and amunt f data being sent Higher bandwidth allws mre data intensive applicatins including streaming vide, pictures Passing mre data means mre data t prcess, bth at the PSAP and in the field Prcessing f data will take time and resurces, thus increasing the amunt f time t prcess each call (fr nn-traditinal calls)

6 PSAP Cnsideratins Hw d yu mange new types f data? Dedicate a psitin in the PSAP t handle Textt messages? Screen messages and filter data? Send everything t the field? Recent article summarizes cncerns: Public-safety representatives wary f tsunami f data frm text-t- 911 services, NG-911 (Urgent Cmmunicatins April 9, 2014)

7 Distance vs. Capacity The further a device is frm the center f an LTE cell site, the slwer the data speed is and the less capacity there is.* Distance frm Center f Cell Dwnlad Uplad 1.25 Miles 34 Mbps 16 Mbps 2.00 Miles 25 Mbps 12 Mbps 3.00 Miles (edge f cell) 768 Kbps 257 Kbps *APCO Technlgy Frum Public Safety Bradband 12/03/2013 by Andrew M. Seybld

8 Typical Data Per Applicatin Accrding t the Federal GAO reprt n data capacity and rates: HD reslutin vide will require 3.5 Mbps f data capacity Typical vide sent frm an incident will require 1.2 Mbps f ttal available capacity At the edge f the cell sectr, nly lwreslutin vide will be pssible

9 Field Cnsideratins Large incident may exceed bandwidth capacity and will require careful management Priritizatin f applicatins is critical (ensure high pririty messages g thrugh) Crdinatin between users and agencies becmes especially imprtant (manage bandwidth using NIMS type f apprach) Infrastructure may be damaged thus further limiting cverage and capacity

10 Recmmendatins Plan fr bandwidth verutilizatin during majr incidents (CONOPS, training, lessns learned) Discuss pririties with first respnders Priritize the types f infrmatin needed Priritize users (COML) Utilize existing resurces APCO Standards Develpment Cmmittee (standards, best practices, methdlgies) APCO Bradband Cmmittee NPSTSC 700 MHz Bradband Wrking Grup NENA PSAP Operatins Cmmittee

11 Recmmendatins (cnt.) APCO magazine April 2014, Reality f Bradband Standards fr First Respnders Marketing hype vs. reality Nt all respnders need t generate data Develp new CONOPS t: Manage uplad and dwnlad f data Determine wh generates, wh manages data Ensure nly timely infrmatin needed t manage the incident is transferred Dn t distract r add t first respnder wrkflw

12 Cnclusins NG9-1-1 and Public Safety Wireless Bradband/4G LTE will prvide the capability t prvide significantly mre infrmatin t the PSAP and the first respnder Managing the data will require increased time and resurces fr the PSAP Intelligent disseminatin f this data frm the PSAP will be critical t the first respnder in the field PLAN IN ADVANCE!
