​Get involved with GWTCA.

The new administration in Washington, DC, may bring changes in wireless policy and staff assignments at the FCC. It is vital for those engaged in Public Service and Public Transit telecommunications to take an active role and ensure you are well represented and your collective voices are heard. This is important for you and your organization since policy issues that could impact your ability to deploy wireless technology and communications are already on our “radar” for 2017.

As a member driven association, our goal is for a significant number of board members to come from Public Service and Public Transit agencies. You can help us form advocacy positons that will impact Public Service and Public Transit wireless policy for years to come by providing your nominations of member candidates (self-nominations are fine too).

If you have a candidate in mind, or if you are interested yourself, let us know and we will send you a member package.

Our Technologies

The demand for wireless technology and communications within the public-transit and public-services sector is increasing rapidly.

Legacy Technologies

LMR is with us for a long time. There is a new realization of the inescapable co-existence of LMR and Long Term Evolution (LTE) systems for many years to come. It’s probably the result of push back from thousands of agencies operating LMR systems. The objective now is to protect your investment through the intersection of technologies. Extend the life of your existing system while beginning to build the new.

Systems interface bridge the key to LMR-LTE interoperability. Industry is being encouraged to develop LMR-LTE system interface devices and encouraging standards development organizations (SDOs) to develop LMR-LTE interface standards. 

The mission-critical push-to-talk (MC PTT) legacy interworking interface, being created by the Third Generation Partnership Project (3GPP), will make one “spigot” available for all other technologies. They will not create interfaces for Project 25 (P25), TETRA, analog or others.

MC PTT faces many challenges. The 3GPP TS 22.179 specification has established stage one requirements for MC PTT over LTE. Release 14 will include mission-critical communications interworking between LTE and non-LTE systems. Key elements to develop are MC PTT, which includes caller ID, emergency alerting, group call, and direct mode or proximity services (ProSe). Direct mode has significant engineering, operational and product design challenges because of the nature of the LTE network. Device-to-device (D2D) operation will take place on the uplink frequency. This may require two receivers within each device to enable continued operation on the network while switching to and from D2D operation.

Emerging Technologies

The top three areas of interest are  said to be, vehicle to “X” communications, internet of things (IoT) and wearables. Here some others:

Dedicated short-range communications (DSRC) - one-way or two-way communication specifically designed for intelligent transportation systems.

Smart Cities” Initiative - new technology collaborations to help local communities tackle key challenges such as reducing traffic congestion, fighting crime, fostering economic growth, managing the effects of a changing climate, and improving the delivery of city services.

FirstNet – interoperability with Public Services and Transit systems.

High-speed railway (HSR) - one of the most sustainable developments for ground transportation. Wireless communications play a key role in the transmission of train control data and wireless communications between the HSR operation scenarios and the conventional public land mobile scenarios.

Transit Wireless Systems - As transit systems gain sophisticated wireless infrastructure for commercial services, transit authorities are starting to utilize these private, reliable and highly secure digital networks for the operation of key transit applications i.e. fare payment systems

4.9 GHz Spectrum – Non-public safety entities, such as utilities, commercial entities, and the Federal Government may enter into sharing arrangements public safety entities to use the 4.9 GHz band in support of their missions.

GWTCA has the experience, expertise and focus on both legacy and emerging wireless technology and communications.

Typical Government Members

Public Service Streets, Roads, Highways, Bridges, Prisons, Parks, Education, Forestry, Works, Justice

Transportation -  Public transit, Commuter Rail, Bus, Subway, Airports, Ports

Special Districts -  PUD’s, irrigation, hospitals, natural resources, drainage, flood control, soil and water conservation, sewerage

School Districts-  Campus Administration, Maintenance, Student Transportation, and Campus Police 

Individual Government Employees

Federal Government Agencies


Government agencies have unique needs for wireless technology and communications to complete their missions. More than LMR, they want new emerging technologies. More than Public Safety, they include Public Transit and other Public Services.

Their unique needs are best met by GWTCA with expertise in these technologies and focus on these users. 

Both First Responders and Commercial Users have trade and industry association "champions." GWTCA will focus on Public Transit and other Public Service wireless technology and communications users, to be their "voice" and focus on solutions for their unique needs.
