Hytera Communications, the world’s second largest solution provider of professional mobile radio communications  has launched a new distributed trunking technology at the International Wireless Communications Expo (IWCE) this week. This new technology, known as XPT (Extended Pseudo Trunk) was developed exclusively by Hytera and enables two-way radio users to proficiently use limited spectrum resources to double their channel capacity without using a dedicated control channel.

Trunked radio systems are two-way radio systems that allow for the sharing of a few radio frequency channels among a large group of users – a form of communication critical for public safety, crowd and traffic control, rescue and relief work, manufacturing and transport operations, and other communications. Centralised trunking, however, requires all activities to be coordinated via a dedicated control channel, which is difficult to obtain under the Federal Communications Commission (FCC). XPT solves this problem by using an innovative distributed digital trunking technology.

XPT enables customers to trunk without using a dedicated control channel, enabling them to double their capacity while leveraging their current spectrum resource, in ways that are simpler and much less expensive than other market options,” said Dr. Ke Lu, vice president, marketing and strategy, Hytera. “Airport staff can now have more user groups to increase operation efficiency; facility managers can better coordinate with security guards and maintenance; factory managers can play back voice recordings even against a background of loud machinery; and hotel customers can use the room telephone to call housekeepers’ radios directly.”

Hytera XPT Digital Trunking

XPT equipment can set up eight 12.5kHz FCC channels and support 16 voice channels. Specifically within a single Hytera XPT system, the repeaters broadcast the system’s status information in each frequency via a beacon signal which informs the radio of available channel resource. The radio can then switch to an available channel and slot to communicate. The result enables multiple users across various departments to quickly and easily handle critical communications and requests. There is no dedicated control channel required by a XPT system.

Benefits of XPT Digital Trunking  

• No dedicated control channel. XPT employs a distributed trunking protocol which does not require a dedicated control channel, which is hard to obtain, providing greater flexibility to many end users who are now able to build a trunking system in a shared channel environment.

• Higher capacity. A single XPT system can support up to eight repeaters at one site and provide up to 16 traffic channels, supporting up to 1,200 users. Each traffic channel can be customised to transmit voice or data.

• Easy migration from DMR Tier 2 Conventional to XPT digital trunking.  XPT can be enabled by upgrading the firmware version of current conventional Hytera digital radios and RD98xS’ series repeaters. XPT also supports the digital functions of conventional systems, providing key digital mobile radio (DMR) benefits yet using entry level digital repeater configuration.

• Extremely cost effective. XPT is a simple solution that enables customers to migrate many aged analog Logic Trunked Radio (LTR) systems to digital, leveraging their existing infrastructure without significant capital investment. The solution is easily installed, maintained and operated, and is more cost-effective than other market options.

Hytera X1p an RD965- Philippines Deployment

Disaster Tech Lab use WiFi to reconnect disconnected communities in disaster zones.They operate from a bottom-up, grass roots perspective driven by the needs of those who they help. Prior to deployment of Hytera radios to aid typhoon Haiyan in Philippines, Disaster Tech Lab faced a challenge. There were no communication channels available for their team in the areas they were operating in; any pre existing communication services were disrupted due to the typhoon.

Working in remote locations, Disaster Tech Lab were looking for a handheld solution which would allow their teams as well as individual team members to communicate over short to medium distances. The criteria for the ideal radio was simple: the radio had to be portable, durable and easy to use (requiring
minimum of training). It also had to be rugged and able to withstand high temperature variations. A team from Disaster Tech Lab were equipped with 5 Hytera X1p radios, an RD625 and a MCA10 multi charger.

Hytera X1p

Small, compact, lightweight and easy to use, X1p handsets were proven to be the ideal radios for the job at hand. These radios provided clear and interference free communication over the various distances despite being used on top of hills and with vegetation in the way. High humidity levels and rain had no affect the radios performance as there were no reported signal degradation. Having efficient wireless communication enhanced the team efficiency and bought down the overall time required to install and test the equipment which Hytera had supplied.

Hytera RD965

The RD965 is Hytera’s first digital/analog portable repeater built to DMR standard. The powerful integrated features such as the analogue and digital call support, the ability to guarantee uninterrupted communication during an emergency, the high level encryption two concurrent calls through the same base and IP connectivity as well as its IP67 protection made this the product reliable in the hostile environment the Disaster Tech Lab team were working in.

Hytera MCA10

This was installed in a vehicle and powered using a Goal Zero battery and two solar panels. The combination of such power supply was more than effective keeping the handsets powered up any time they were required.

Hytera Communications; world’s leading professional communication solution provider have officially signed a sponsorship contract with Mark Wood; The Polar Explorer for 2015. Hyteras TC-610 radios will be taking part in an arduous journey climbing mountains and sailing off off into the sunset visiting countries such as Norway, Iceland, Himalayas and Oman.

Mark Wood is focusing on raising awareness for climate change and the challenge for this Mountain Expedition is to persuade individuals and businesses to cut carbon emissions. Whilst on this expedition it is important for Mark Wood to be able to communicate effectively with his team on the group and also his partner who will be accompanying Mark on this voyage.
