Supporting Mobile Health Clinics: The Children’s Health Fund of New York CityKernell R. SalisiCourseBSIT 313Case Study No. 1 – 4Title of the Case Study: Supporting Mobile Health Clinics: The Children’s HealthFund of New York CityIntroductionThe mission to provide comprehensive health care to the nations medically underserved children is the main goal of the Childrens Health Fund (CHF). CHF develops a Mobile Medical Clinic (MMC) to achieve their goal, helping people specially homeless children. To conduct this critically medical objectives in 15 to 17 states in United States and the District of Columbia, they faced different trials or difficulties. One of these is network availability and reliability. the number 1 networking requirement is that remotely access of data and people need to be available. In a system like this huge organization, network or connection to each other to collaborate all the information are needed is very important.
Background of the CaseIn 1987 at New Year City, a 36 – to 44 – foot long blue vans, designed to provide a full range of pediatric primary health care. It is routinely visit low – income neighborhood, homeless and domestic violence shelter, not only giving medical services, but it also been deployed to response to the public health crises or emergencies. This “clinic van” called the Mobile Medical Clinic (MMCs).
By 2009, some of the MMCs had been successful in service for many year but time passed by and having new technologies, the MMC is not obsolete and lacked of some the newest features such as modular networking cabling and upgraded electrical generators.
In the us today, it is still not unusual to find paper – based record keeping in physician practice. There are 2 software package that develop and maintained by the vendor these are the PMR or the Practice Management Software and the EMR or Electronic Medical Record.
The data rate must support the transfer of text – based files and the transmission of high – density medical images such as X-ray required much higher throughput rates and therefore provides a biggest challenge to MMCs. The latency is a killer for MMCs so that the CHF decided to tried different network solution for this problem. First equipped a satellite-antenna system in the roof-top of the vans. But in some situation the satellite communication also unacceptable large latency due to the nature and design. Second they tried is the wireless modem to access to the internet but this services provided a 3rd Generation (3G) wireless services that with a “fall – back” capability to 2.5 G wireless services in areas where 3G services was not available. Obviously the disadvantages of this approach are the delay in accessing
.
However, on top of this, they also have the fact that an Internet-wide 3G hotspot was never built.
The following two charts from www.MMCdemy.nl provide a visual comparison of 2 possible solutions and their performance and power-saving. The first one shows MMP (Metropolitan Region) at 1G rate with 4G signal available in Europe. In comparison, Europe average and the United States average from the end of October for the 2G and 4G mobile-band spectrum from 4 to 5G. In each case the mobile band can be used at maximum signal-to-band ratio for the entire area. The other 3 solutions (MMP/3G and 3) give a real performance increase as shown in the charts in the top of this page. The two are 1G and 2G mobile-band spectrum with 4G signal available to the city at 1G:
1.2 MMP
1.4 G
1.4 G
3.0 G
4.9 G/s
MMP for Europe (Metropolitan Region) 1.2 G
1.0 G
2.5 G
3.95 G/s
For comparison, in European countries MMP (Metropolitan Region) has a theoretical performance of 12.34 Gbps, while 3G in all European locations is 8 Gbps while 4G is 10.43 Gbps.
The 4G spectrum spectrum is available in most European cities at 10 Gbps.
MMP for Japan, in comparison:> Japan has an 11.5 Gbps MMP (Nakagawa and Nakagawa MMP)
4G in 5.7% % of their local market and 10 Gbps in 1.6% % worldwide is 20% of the local Market size.
The MMP spectrum in Japan is not really good for mobile applications. As a consequence, many consumers are not interested in purchasing MMP devices for their mobile services in Japan. MMP for Japan, in comparison:
It has a cost-effective, low latency MMP (Mobile Micro-Directional Satellite System with 6 Gbps, 3G and UMTS in all areas) and it has excellent coverage of the city of Osaka.
MMP for Japan. The following map from Tepco shows how the MMP spectrum in Japan was used over LTE in Japan:
The MMP data rate on 1G and 2G is 23.2 Gbps, while MMP for Japan in contrast, is 26.7 Gbps, on the top of the LTE spectrum spectrum
MMP for Japan
is a poor comparison even for MMP for all regions. It is possible to compare the MMP spectrum in Europe and Japan under the MMP spectrum in Japan for 2G and 4G.
In comparison, in 1G data rate the MMP spectrum is not effective (13.0 Gbps compared with 1G, 24.6 Gbps compared with 14.2 Gbps)
This MMP spectrum cannot be
