Hytera TETRA Radio System Ready for Take-off at Luanda Airport in Angola

Hytera TETRA Radio System Ready for Take-off at Luanda Airport in Angola

SGA is the operator of the main international airport in Luanda, the capital of Angola. However, its old analog radio system was no longer adequate for SGA’s requirements. It needed a modern digital radio system with wider coverage, more radio channels, and one able to support more applications. Hytera supplied its latest TETRA two-way radio solution with a Smart Dispatch system and PT580H Plus handheld terminals. SGA can now manage airport operations much more effectively to ensure a more efficient operational environment for its airline customers and passengers.

Challenge

The existing out-of-date analog radio system was not fit for purpose. Most of the SGA airport staff did not have access to a radio, which made it challenging to coordinate airport operations in an efficient and safe way. 

The airport environment itself has a high noise and signal-to-interference ratio, resulting in poor voice quality for those that did have a radio. Another major difficulty was the lack of channel resources of the analog network. This meant that even though there were only 50 users, communications were constantly hampered by having too few radio channels, forcing callers to queue. Again, this impacted operational efficiency.

SGA needed a radio solution with the necessary coverage and capacity, good sound quality, lightweight equipment, and one that enhanced safety and reliability, but which was also cost-effective.

The project also faced the challenge of a lack of local expertise in implementing radio projects. The local radio channel dealers did not have the required delivery capabilities, so it was necessary for the radio manufacturer to send experts to help deploy the equipment, train the users, and help deliver the overall project for the customer.

Solutions

SGA implemented a Hytera TETRA two-way radio network featuring the latest ACCESSNET-T IP Smart system, marking its first deployment at an airport. The solution included a DIB-R5 outdoor base station, a dispatch system, and PT580H Plus handheld radios. The TDMA-based system increased channel capacity while the DIB-R5, built for extreme temperatures and IP65-rated, ensured reliable performance with low power consumption and support for solar or DC power.

Hytera's scalable, cost-effective solution minimized CAPEX and OPEX with reduced infrastructure needs, remote configuration, and Linux-based SMART software for easy maintenance and upgrades. This robust system delivered advanced, secure, and efficient communication tailored to SGA’s needs.

About SGA

The National Airports Company (Sociedade Gestora de Aeroportos - SGA) is the current operator of the 4th of February International Airport in Luanda, the capital of Angola. The 4th of February International Airport is the current main international airport of Angola, which is located 5 km to the south of the centre of the capital. SGA was restructured in 2019 from its predecessor, the National Airlines (Enana).

Benefits

Full Coverage

The TETRA solution meets the needs of SGA’s airport and control tower staff as it provides full coverage across the whole of the airport to ensure smooth and reliable communications.

Cost-effective Solution

The Hytera ACCESSNET T-IP SMART TETRA system delivers a lightweight solution that saves users money while creating value. It combines the latest Hytera hardware and software innovations to help reduce both CAPEX and OPEX costs, including ongoing operational and maintenance costs.

Additional Capacity and Ease of Use

The TETRA system provides more radio channels to easily support the 50-plus users. The additional channels means specic talk groups can be created to separate out different job roles. This avoids clogging up the radio system with calls having to queue for a free channel.

Smart Dispatch and NMS

The web-based Network Management System and Smart Dispatch system with its easy to use interface makes it simple to support a variety of applications, including dispatch of workers with just one click. It also enables efficient radio fleet management, maintenance and software upgrading via OTAP (over the air programming).

Loud, Clear Audio

The PT580H Plus features an advanced audio chip with the latest noise cancelling capability, which means users working in noisy environments still get excellent audio quality. The 3W transmit power improves coverage and makes communications easier to hear.

Rugged Handsets

The terminal is IP68 certied, which provides a very high level of protection against dust and water ingress. It also meets the MIL-STD-810G standard for drop, shock and vibration resistance.
