Hong Kong Modern Terminals Deploys Altai Super WiFi

Overview

Hong Kong Modern Terminals is one of the busiest container ports in the world. Modern Terminals currently operates 7.5 berths with total handling capacity of 7 million TEUs.

The traditional mash AP network was not ideal for daily logistic operation due to the complexity and high interference signal at the berths as well as the constraints of site facilities. Besides, the WiFi signal is usually blocked by mobile cranes and containers.

The adoption of Altai wireless solution is divided into two phases. In phase one, 5 Altai A8 WiFi base stations have installed in berth no. 1, 2, 5 and 9 to cover the whole container terminal with wireless broadband network.

In the container port, long range technology is required as there are limited sites for equipment installation.

The Challenge

  • Have to provide stable WiFi signal.
  • Require multiple base station coverage to every client.
  • Only limited sites are available for installation.
  • Require high data transmission throughput and low latency.
  • Need to support triple play WiFi including video streaming and for other interactive applications.

The Solution

  • Five Altai A8 base stations have mounted on the 30 m high light towers to provide total coverage to berth no. 1, 2, 5 and 9.
  • 20 A8 installed for full multiple coverage (7 BTS/km2 vs. original 60 AP/km2)
  • Altai Network Management System (AWMS) is used for monitoring the network performance.

The Result

Providing 7X increase in area coverage than the traditional mesh AP. One A8 covers more than 600 m over cranes and 300 m NLOS over container stacks.

Each base station provides 3X in data transmission throughput that is 20 Mbps access throughput to users without the need of hopping.

Altai wireless broadband solution provides backhaul protection and interference mitigation.

Reducing the number of mounting locations, these help minimizing the entire cost of deployment and maintenance.

The AWMS not only provide performance and fault monitoring on network, but it also provides a lot of statistical information on mobile client management.
