Hong Kong Container Port Wi-Fi Case Study
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. (Container ship capacity is measured in twenty-foot equivalent units (TEU).)
The traditional mesh 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. The WiFi signal was usually blocked by mobile cranes and containers.
The adoption of Altai wireless solution was divided into two phases. In this case we follow phase one installation which included 5 x Altai A8 WiFi base stations installed in berths no. 1, 2, 5 and 9 to cover the whole container terminal with wireless broadband network.
Long range technology was imperative here as there are limited sites for equipment installation.
- Providing stable port Wi-Fi signal.
- Multiple base station coverage to every client.
- Only limited sites were available for installation.
- Require high data transmission throughput and low latency.
- Need to support triple play WiFi including video streaming for other interactive applications.
- 5 x Altai A8 base stations were mounted on the 30 m high light towers to provide total coverage to berth no. 1, 2, 5, 9.
- 20 x 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.
Providing 7X increase in area coverage than the traditional mesh AP. One A8 base station 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, which helps to minimise the entire cost of deployment and maintenance.
AWMS not only provided performance and fault monitoring on the network, but also statistical information on mobile client management.
Competition: Cisco, Motorola
Over six months’ testing on stability and performance, the results proved that the Altai A8 WiFi system not only meets all the specifications but also exceeds our expectation. The same test was conducted for another AP at the same time, and all the test results of Altai outperform that of traditional AP.
