Femtocells (MicroBTS) in support of Emergency Communications
| Image http://tinyurl.com/oxkclcd |
A small deployment, in a disaster affected area, could serve the public in small batches allowing them to reach their loved one. The Federal Communication Commission of USA has discussed the use of Femtocells as a Public Safety Tech. US telcom operator AT&T supports some mini systems that they use for their own emergency deployments and also offer to emergency management teams. The suitcase size, bigger than Femtocells, AT&T solutions can support 500-1500 users simultaneously. Depending on the bandwidth available they do a decent job, at least with voice.

Pasquale Pace and Valeria Loscri published on the architecture of OpenBTS as another step forward towards establishing cost-effective Micro BTS solutions. Range Networks has primarily customized the openBTS platform for a Network in a box kind of offering. They have a handful of implementations in various parts of the world: Antarctica, Indonesia, and Zambia. Folks at Daes and Orangee have discussed their practical experience of implementing a OpenBTS-enabled Microcell.

Of cause there are legalities with frequency reuse by an unlicensed service provider. There must be roaming agreements between providers to use the same frequencies in the same area; i.e. multi-carrier compatibility to allow for a femtocell to communicate with handsets from different carriers. It doesn't affect or matter who's at the other end of the line. Government agencies have the authority to overpower those licensing barriers. A Micro BTS setup by a Government emergency service can certainly override those licensing issues. Another option is to offer a set of emergency frequency bands that any authorized service operator can use to operationalize a Micro BTS in the time of an emergency.
The back-haul can simply be a broadband (internet) link to pipe the cellular signal. For example, a VSAT connection can serve as back-haul in a cellular dark area caused by a disaster . However, one must be cautious of the latency that comes along with satellites back-haul. Moreover, it has to have some form of authentication to interface and establish routing of the call in both directions. Establishing a satellite link in between would likely fail because of latency and technical routing problems. Mobile phones require specific performance characteristics that are not one size fits all that can be accommodated by one system.
While Femtocells have certain challenges with operationalizing that are mainly due to policy and regulatory issues, it still is a promising technology for serving the gaps of filling the dark cellular coverage holes in support of crisis response and management.

Embarking on a study of ICT use in Indian Emergency Communications
| Image is from DownToEarth: http://tinyurl.com/l6tqhpa |
Realizing the shortcomings in the robustness of telecommunications in serving crises the Department of Telecommunications (DOT) of the Government of India and the International of Telecommunication Union are committed to intervene. I am honoured to be granted the opportunity to lead the study in determining the gaps and then recommending best-practices that can be leveraged in improving the Indian emergency communications.
The objectives are:
- Evaluate the current situation of ICT use in Emergency Telecommunications; specifically in the preparedness and response components of a Disaster Management cycle.
- Suggest optimal use of satellite and terrestrial systems to developed redundant stream-less communications by first assessing available ICT resources and processes to effectively meet the challenges.
- Create ecosystems where investments made for deploying telecommunications infrastructures for economic development are also used for disaster response for public safety.
- Challenges to bring in coordinated approach from different government departments, Service providers, private sector, intergovernmental organizations for effectiveness and quick response.
- Recommend any areas that require capacity building, systems development, and procedures for resilience. Thereafter, provide best practices that would support those recommendations.

APT Manila meeting leading to Sahana Center of Excellence at AIT
The panel was Chaired by: Dr. Eun-Ju Kim (Regional Director, ITU Regional Office for AP), Mr. Wisit Atipayakoon (ITU Regional Officer for AP), D. Manluz Hazarika (AIT Geoinformatics Center Assistant Director), and myself. The panel topic termed as the "ITU Session".
A noteworthy historic event was meeting Manzul who is affiliated with the Asian Institute of Technology (AIT) Goeinformatics Centre. His presentation was on: Applications of Geoinformatics and Space Technologies for Disaster Risk Reduction (DRR). Besides speaking of CAP, I also spoke about the Sahana Disaster Management Software, specifically the developments of the Sahana CAP Broker. Then we got to talking about ongoing and possible future projects. Our conversation continued at the Ninoy Aquino International Airport, Manila.
The propositions were on combining the AIT Goeinformatics remote sensing and risk mapping technologies with the Sahana Software. The pre-disaster risk mapping exercises would complement the alerting and post-disaster incident reporting. The integrated technologies would offer solutions for Regional Governments and In-line Organizations. That is when I brought up the idea of a Sahana Centre of Excellence at AIT.
The intent of the Sahana COE@AIT would be to foster research and development capacity at the Goeinformatics Centre to provide the essential information management systems and the know how. Manzul and I agreed that we would set sail with this idea and fine resources to make it happen.

Closing the voice-enabled disaster communication project but looking to do more
-->
Summary of the VoiceICT4D project outcomes
- LIRNEasia, through a stakeholder forum, advocated the Sri Lanka Disaster Management Center (DMC) to move towards a multi-agency situational-awareness platform by creating a register of alerting authorities and then sharing it's call center and Interactive Voice Response (IVR) system resources for emergency communication.
- The “Do you Hear Me” video, communicating the need for voice-enabled Information Communication Technologies (ICTs), to empower community-based emergency coordination, was visited by 496 viewers, of which 48 or them shared their knowledge on the subject. UNISDR debut film festival on DRR, selected our video as as one of the best three in the category of “best human interest story”
- Peer-reviewed scientific articles presented the realization study evidence emphasizing the practical technical instabilities and deficits in those technologies. The message was news to most researchers and practitioners. IVR-based solutions are gradually gaining momentum.
What next?
- a radio station would manage a missing persons registry comforting concerned citizens of who are missing and who were found
- citizen journalists would share risk information of incident reports to effectively coordinate and respond to those troubled situations
- community-based disaster management organizations would coordinate their rescue and relief efforts using interactive voice.

Beyond Tsunami Warning in a Vocal Society
The Government of Sri Lanka failed to warn the fishermen of the deadly mini cyclone that lead to 29 deaths. Detection theorist may label this incident as a missed alarm but essentially it is a true alarm with failed actions. There was a lot of finger pointing between agencies for one denying the responsibility over the other. Such a tragic situation could have been over come if a register of alerting authorities with a profile and procedures and a multi-agency situational awareness technology platform had been in place. The DMC held a stakeholder workshop to discuss a way forward.
With respect to incident 2), the tsunami evacuations continued even after the threat was called off, which insinuates a lack of competence. Decision theorist, from the eyes of a Policy-maker's loss function (i.e. government bureaucrats and politicians prospective), would consider this as a success; thus, the ability to warn of any tsunamigenic earthquake. However, from the eyes of Stakeholder's loss function, such as fishermen not going out to sea anticipating a tsunami, the false warning deprive them of a days house hold income.
The Public Lecture was partially funded by the Humanitarian Innovation Fund (HIF) through the VoiceICT4D project. The aim of this action was to strategically address the public at a right time when the message was sure to be heard by those who should hear it. The lecture presented the formula for removing the aforementioned uncertainties. The Director General of the Sri Lanka DMC, himself, was present at this lecture and was appointed the task of moderating this event. His words following the main presentation was “thank you Nuwan this is an eye-opener.”
The public lecture message intended for the Director General and the audience to hear was that the inter-agency rivalry and reduction of false warnings can be achieved through the adoption of interoperable emergency standards along with the policies and procedures that wrap around those standards. The VoiceICT4D project was designed to educate society of the power of voice-enabled technologies and interoperable data standards. A summary of the Public Lecture talks, on LIRNEasia's blog, outlines the key points.
Sri Lankan's, like most other Eastern societies are accustomed to talking to one another over the phone whether it be personal, business, or informing each other of a crisis, more so than text-ing. The video “do you hear me?”, which was produced through the HIF grant, was screened to remind the public and the DMC of the local requirement. Coincidently, the DMC had invested in a call center and an IVR for emergency information collection and dissemination. LIRNEasia has offered to share the lessons learned from it's voice-enabled ICT for Disaster pilot.

Making Emergency Communication Effective

CAP Text not allowed to Speak in USA
Excerpt from the article – Many of those in my community have a hard time understanding the current version of text to speech. In other words, us old folks can’t hear what the computer is saying. There’s also the issue of geographical differences in words. For example, is “soda” and “pop” the same as “soda pop” or “Coke”. If one were to write “I’d like a Coke and fries”, the computer will read that hearer may need more information, ex. “We don’t serve Coke, is Royal Crown Cola OK?”
Here's what I had to say in the LIRNEasia blog relating it to the Freedom Fone and Sahana project.

A nifty way to test Speech-To-Text uncertainties with ITU's Difficulty Percentage measure
Emulating Speech-To-Text Reliability with ITU Difficulty Scores
"The results show that with a speaker dependent system 95% of the information could be clearly deciphered opposed a speaker independent system that was only 70% clear (blue areas in Figure 1 and Figure 2). It is not surprising, the outcomes are intuitive. In our study reliability had two components, one was efficiency and the other was voice quality. The voice quality also took in to consideration the Mean Opinion Score and the Comparison Categorical Rating. The researchers wish to acknowledge that their may be disagreements in the sample sizes and number of Evaluators. These results are not ideal for drawing a ‘for-all” kind of conclusion. However, at this realize stage of the research it provides a quick and easy method to draw initial conclusions." ...Click to read full article

I was thinking addressable satellite radios but they are not two-way communication devices. HF radios for data transmission may be another way to bridge the last-mile?
These observations were made during the "ITU Asia-Pacific Regional Multi-stakeholder Forum on Emergency Telecommunications", which was held at Chinggis Kaan Hotel, Ulaanbaatar, Mongolia, 08-11 July, 2011. I presented on our experiences with the Common Alerting Protocol and also submitted a supplement brief that recommends member states to register alerting authorities.

Now a member of Sahana Project Management Committee
The first Sahana conference took place in Colombo, Sri Lanka during the last week of March, 2009. I made two presentations (biosurveillance and common alerting protocol) and Prof. Samarajiva one (public warning), which stated our (LIRNEasia's) commitment to Sahana.
Sahana has divested from the original parent Lanka Software Foundation and has been incorporated as a foundation in the state of California, USA. Work is still in progress in establishing the foundation.

SMS Transport for GSoC 2009
One of my initial ideas had been to develop a SMS transport that mimics IP where data can be exchanged between a mobile client and a server (database). This is to address the problem faced by emergency coordinators in communicating field data to central levels and receiving information during the response stage of a crisis. Network congestion is a fact during the peak or initial stages of a crisis. Hence, voice channels are the first to shut down. Other means such as GPRS signals are not always up to par and in most cases would be weak in covering remote location that are in the periphery of the footprint of cellular towers. However, SMS that works on weak signal strength, a store-and-forward communication technology, even though may not send the information in real time, would eventually get the data across to the terminal devices.
Presently Sahana, a web browser application, reliant on Internet connectivity for data exchange, is developing a class of mobile phone and personal data assistant hand-held device applications to operate in the field. These hand-held devices are handy effective tools in data collection and reception. Although GPRS exists as means for providing connectivity, given the question on reliability, it is important that a redundant or alternate channel for transferring information is in place, if Sahana applications are to be effective across available communication network platforms.
The problem that this project promises to solve is to develop an SMS transport layer that can communicate with the Sahana applications during times of need. This proposal outlines the goals and design of the envisaged software object that will work as a general protocol to support all Sahana modules for networking with hand-held terminal device applications.
The Sahana community has definitely selected the student who has provided some original ideas and proven skills to develop the client and server side components. Some aspects that the developer must keep in mind are compressing the strings to minimze on SMS tariffs are multifold relative to GPRS, sequencing the SMS pages to ensure they are chained back at both server and client sides. Some thoughts such as use of binary XML has been suggested to structure the server calls or client requests and data exchange between the Sahana clients and Sahana servers.
I'm excited to mentor the student in developing this component as part of GSoC2009 for Sahana.
