Push to Talk over Cellular (PoC) – The future of Push to Talk Communication?

What is Push to Talk over Cellular (PoC)?

Push to talk over cellular; as the name suggests, is an emerging technology that combines the well-known ‘Push to talk’ capability commonly used in two way radios with 4G cellular coverage. Due to utilising 4G the devices have very wide coverage being able to communicate with any device that has 4G coverage.

What are the advantages of PoC?

Aside from the aforementioned wide are coverage there are many other advantages to PoC compared with a traditional two-way radio system. Some of the key advantages are listed below:
• No infrastructure costs – compared with traditional wide area systems which have very expensive set-up costs.
• GPS tracking – Push to talk over cellular allows users to track individuals in real time with the Dispatch feature.
• Versatile Contracts – You can easily manage data, with no lengthy contracts to sign up to.
• Compatible with Multiple devices – SFL’s PTTOC platform works on a wide range of devices that we supply. It is also compatible with Android and ios devices and we can supply a licence only package if you would like to use your own device.
• Features – PTTOC devices have the ability to support a wide range of features including man down and lone worker.
• Flexible payments – The devices are available both for hire and purchase and packages can be tailored to meet your requirements.

Is PoC the future of Push to Talk Communication for Businesses?

In today’s fast paced work environment flexibility and adaptability are key. Whilst undoubtable there is still a place for a traditional two-way radio system, particularly in areas where 4G signal is not available or in high risk industries such as construction, PoC offers a great alternative for many potential users.

PoC is particularly useful for those working across multiple sites and SFL have customers already benefitting from such as system. With ever increasing areas of 4G coverage and development of new technologies such as 5G the reliability and performance of Push to Talk over cellular is only set to improve and as such its viability as an alternative to two-way radios is going to become appropriate for more users.
