Thu 11/1/2012 3:15 PM

Good afternoon.

Attached please find Spacenet’s response to the “Notice of Intent” from the First Responder Network Authority (FirstNet) and the NTIA  regarding implementation of a nationwide Interoperable Public Safety Broadband Network. 

As one of the nation’s leading Satellite Service Providers, Spacenet has a long and rich history in supporting the communications needs of the first responder community.  Spacenet feels very strongly that satellite communications must play an integral role in the network infrastructure for this nationwide broadband network.  During times of catastrophic events such as hurricanes, earthquakes and tornado’s, satellite communications may be the only communications infrastructure still operational and can be deployed very rapidly.

Please forward any questions or comments to me.

Best regards and good luck.

The City of Eau Claire is participating in the CCI portion of a recent BTOP grant to provide broadband services to the Chippewa Valley.  Part of the project is a WiMax pilot to be used for public safety, education, medicine, and municipal operations.

We are currently using WiMax for our deployment but plan to upgrade to LTE once an open standard is established.  The 700 MHz freq. will be also be considered once the open standard is accepted and equipment is available.

Our coverage area includes a majority of Eau Claire and Chippewa County and a portion of Dunn and Clark Counties.  We are utilizing 14 tower sites and the pilot involves 20 different organizations.  We are also looking at connecting our system with the Wausau area 70 miles to the east to share the controlling systems to provide interoperability between the two wireless networks.

This pilot has proven to be a tremendous improvement in delivering connectivity to applications both mobile and point–to-point,  when and where it is needed.   However, it is just a pilot, and further funding is required to expand coverage to the rest of our frequency area.

With our communities current budget challenges it may be years before expansion of this interoperable network could take place.  Please consider Western Wisconsin for future grant funding to expand our network to other communities that would value from it.

If you are interested, and want more details on what we are doing, feel free to contact me.

Good morning, I received a email on welcome comments on the WISCOM system. Just a explanation of who we are, we are a non profit volenteer ems group that has 28 members. Our county is Kewaunee county and we just started to change over to the wiscom system. I do believe this is a good route to our radio situation however the cost of the system will determine the ability of our group to continue. We purchase all new radios 2 years ago and are told the grant money is already used up. It would be very helpful if there was more grant funds or no interest funding to allow groups like ours to make the switch over to these radios and pay them off over a time period. We simply can not afford to supply 28 new radios at $1800 per radio.

Dear FirstNet:

Attached is a white paper from Lemko Corporation that offers a different network architecture than the traditional centralized core architecture. It is revolutionary and game changing. It can be deployed at less than half the cost (considering Cap Ex and Op Ex expenses) as a centralized core network. It eliminates single point of failure issues and is the most redundant and robust approach available. The paper discusses disasters of the past and compares the failures of the networks versus what could happen with a Lemko based network. Thank you for your consideration.

Development of the Nationwide Interoperable Public Safety Broadband Network

Rex Buddenberg

To whom it may concern,

I have been one of the main system engineers on the UK Airwave Tetra system (2000-2005) and the now defunct New York Statewide Wireless System (SWN: 2005 – 2008) and I have some comments, lessons learned, and observations that I would like to provide:

·        I agree: It is wise to work with the cell phone operators especially with respect to digital data. The data feeds available through the trunked radio are very limited ( a few Kbits/sec) and will never provide the bandwidths that are required for some of the nice-to-have applications. In the UK packet data (GPRS) from commercial cell phones was encrypted and “tunneled” into a secure subnet within the IP network. Within this subnet there were servers available that would permit warrant, CAD, and other types of direct searches. Access to these servers systems is available only if the user can be sufficiently authenticated. The authentication and the access to nation databases will likely be an issue that needs to be worked on from the beginning, since many older rules still apply from mainframe days. Encryption standards were equivalent to FIPS II in the UK. The ground rules for the trunked native classified voice and data also enter into the equation here since secure access by federal services will likely be required at some point. Will voice and data be rated at a secret level or potentially higher? The UK wanted military access at the secret level, and hence radio basestations had their own keys that reported to encryption servers. Will there be similar requirements on FirstNet? Voice and data integrity needs some deep though for this new system, and will likely require packet switching, labeling, and prioritization. In the UK data from the police/fire radios also tunneled into the same subnet within the system. This IP data from the radios could also access the national databases via a reduced graphic interface. The suggestion is that the radios have the ability to roam to the data network with the most available bandwidth. This would include the tunked radio bands, the commercial data networks, and WIFI networks. For example fire may need to download maps  of building. This might be done at lease partially by WIFI before the crew leaves the building and might be able to require WIFI at the local destination. Police cars might have a WIFI link that broadcases locally in the vicinity of their car so that a portable table can be taken into the house or locality to do reporting and requests searches. The car then uploads the buffered results into the network. Bottom line: the basic bandwidth is sufficient for voice and very limited data, the future data expansion needs to come from the radios roaming to other networks when they are available. One of the major benefits of central application infrastructure is that CAD systems and access to national, state, and local resources can be cost shared.

·         Caution: one of the reasons that SWN failed was that the radios attempted to download user talk groups and other local site information before the radio could effectively be used. This resulted in some radios not being “on-line” for  a few minutes while this data became available in low signal areas.  This was totally unacceptable since officers going to a bank robbery, for example, were unacceptably delayed. The Tetra radios on the other hand had a built in chip that supplied user talk group, encryption, and personal information.  The problem with the tetra radios was that the radios became user or user group specific and the chip was too fragile to be put in and out on a daily basis by specific user. Good radio requirements make a difference here.

·        The major issue with a large police radio networks is availability and reliability. It’s very hard to take down individual radio system that are scattered around a very diverse area. A national system must have multiple redundancies: multiple trunking lines, multiple redundant servers, switches, and server sites. The big issue with the associated commercial vendors is going to deal with the details of how reliability is implemented during normal and emergency situations. Who gets the bandwidth when something important is happening? How will the basestations implement emergency level priorities on the sites switching? How will the firenet developers know that sufficient testing of these emergency protocols is implemented correctly in a network that is shared? What is to stop them making a change in the basestation and network code after the testing is complete? Who will approve code changes? How will an industry that is known for its speed to deploy new features deal with the need for increased security, availability, and reliability? …which takes much more time. The main argument is that police and fire radio systems must be always up and always available because people’s lives are at stake. I am not saying that such a shared system cannot be deployed but the system engineering and operational concepts are going to be very important and everyone is going to have to buy into the agreed concepts. They need to be written down (see my bullet on requirements below).

·        Systems and applications need to be tested before being deployed with a new change. That is, applications for radios or tables and the radio code itself must be tested before it is upgraded or patched in a separate independent facility. Changes to servers or other part of the infrastructure need to also be tested before going live – too many lives at stake.  This is done in the UK and it is effective.

·        UK tetra provided coverage via satellite feeds in areas where it was difficult to connect a basestation into the voice and data backbone. The users suffer from a ½ second delay due to the radio propagation times to the satellites. Communication was still possible within these limitations.

·        The requirements and political will for the UK tetra system took on the order of 10 years to manifest and agree. Requirement generation is the first step for the RFP process.  Similarly the requirements for the SWN project took over 8 years to create. Much of this time can be saved by getting a copy of these system requirements and updating them, using the best parts of both, and adapting old requirement to reflect the firstNet network. What is important is the categories and the types of requirements that are contained within the existing requirements specifications, that formed the basis for the RFP. The same type of functionality must be provided and does not need to be redone from scratch. Other states can also contribute their requirement sets: Ohio, Pennsylvania, Oregon, etc. There is always something that is forgotten and could be made better. SWN lacked a complete Network Operating Specification and its reliability requirements had a few flaws that caused problems in the RFP process. UK forgot to include details on how aircraft were integrated into the ground network, and the coverage plan requirements poor such that  airwave took over coverage planning from the vendor. Hence a very major lesson is that a system engineering framework for the billion dollar system is important. Consider the DOD Compreshensive system framework or something similar: http://dodcio.defense.gov/dodaf20/dodaf20_models.aspx

Use some subset of the above that is doable in the time frame permitted (taylor the types of upfront documentation that will be required).

§  Create an operational concept document

§  Design reviews at the system level, state, and local dispatch center level are very important

§  Test plans and procedures must be formal and complete. Every test must be executed and formal. The SWN vendor did not test every requirement on the basestations before they were deployed at 100k+ per site. This caused very significant issues when they were fielded with issues that were unknown by SWN and by the vendor.

§  Specify who does the integration

§  Specify how training is accomplished

§  Specify how coverage will be automatically tested. This is important and caused no end of issues for SWM and for the UK.

§  Make sure that all technical details are available about the vendor implementation of the radio. SWN could not get the subsystem details and system models of the radio system from the vendor so we did not know the lowest acceptable radio signal level, and therefore we did not know if their coverage models were accurate (they did have problems). There were also interference issues that only because apparent in NYC because the technical analysis did not have enough details.

§  Make sure that CPI/SPI for the detailed schedules are available from everyone playing a part in the design and implementation. SWN knew there were CPI/SPI issues and that the project was understaffed significantly but it was difficult/impossible to understand how bad the situation was getting. There was insufficient reporting on a project / business level for a project of this magnitude. The DOD knows how to ask for this type of information when writing an RFP.

Last point: SWN developed very good coverage planning software that the state of NY owns. It was developed through NYSTEC and SRC (mainly SRC). It was capable of optimizing thousands of frequencies across the state, and across state lines through a special automatic optimization algorithms. This software will save you years of work that really can’t be matched by anything on the market. It is a fantastic tool that you are going to want to get or need to redevelop the capability.

I could probably go on but this is all for today. I wish you all the best. You can call or write to me via the details shown below.

On the radio side a technology that is robust in the presence of multipath (and can take advantage of it) and has a high spectrum-reuse should be used. CDMA technologies fulfill that. OFDM does not.

CDMA technologies also currently have the push-to-talk capability, perfect for law enforcement use. Site-teaming allows for multiple antennas at different "masts" to be
"bonded" for higher throughput.

Thank you!
