What is Required for Wireless Data What is Required for Wireless Data Communication Interoperability?Communication Interoperability?

At a minimum, the physical and logical interface components are necessary for wireless data interoperability: – Wireless Data Infrastructure – Wireless Data Exchange

When used together, these two components enable users to interoperate and exchange data communications directly between units and across networks.

Types of StandardsTypes of Standards

De-jure Standards:– Are those defined and approved by a recognized

standardization body such as the TIA, ISO and IEEE.

– Are open standards and ensure compatibility between different vendor’s products.

De-facto Standards:– Are developed by one or several companies that have

established itself as the preponderant standard with the vast majority of users in the market place.

De-jure Wireless Data StandardDe-jure Wireless Data Standard

Project 25 Data Interface Standard:– Open standard developed by APCO.– Allows for data transport at 9.6 KBs using

digital technologies. – Enables different public safety agencies to

interact with one another and to exchange critical information in emergencies even though they may be out of their own primary coverage area.

De-facto Wireless Data StandardDe-facto Wireless Data Standard An assessment survey was sent out to various

wireless data communication vendors asking for:– Vendor Information– Public Safety Agency Information– Wireless Data Communication Interoperability

– Frequency Band of Operation– Over the Air Protocol– Number of Base Stations– Number of Mobile Units– Identify the Coverage Footprint

To determine a preponderant standard with the vast majority of users in the market place.

Identify the Standard to UseIdentify the Standard to Use

De-jure– Is the data throughput of 9.6 KBs too limited

for wireless data communications for public safety agencies?

De-facto– Is there a predominant presence of a particular

vendor to establish a De-facto Standard?

Working Group FindingsWorking Group Findings The Working Group believes the adoption of a De-jure

standard would be inadequate for the requirements of public safety wireless data applications.

The Working Group believes it is important to adopt a De-facto standard to improve wireless data interoperability in the Commonwealth.

The Working Group believes there is a De-facto standard established by one vendor due to the “preponderant and vast majority of public safety users” in the Commonwealth and recommends the De-facto IPMobileNet Wireless Data Specification Standard to be used for the Commonwealth’s Public Safety Wireless Data Communication Infrastructure operating in the 800 MHz Frequency Band.
