Requirements

• Complex and Challenging Environment

  • Urban cities are characterized as a forest of concrete, creating a non-line-of-sight environment for Wi-Fi deployment. Buildings can greatly obstruct wireless signals, limiting the effective coverage. The Wi-Fi networks must be strategically designed and planned to optimize the coverage.

• High Density of Smart Devices and Users

  • Wi-Fi networks must cater to both human users and an extensive array of smart devices. The access points (APs) and backend infrastructure are required to accommodate this high volume of connections.

• Seamless Roaming

  • With APs distributed across the city, seamless roaming is essential, especially for mobile applications such as pedestrians and vehicles.

• Security and Privacy

  • Given the multitude of devices connected to the network, safeguarding data from malicious users is important. Wi-Fi transmissions must be encrypted in compliance with the latest industry standards to ensure user privacy and prevent data leakage.

• Noise and Interference Handling

  • Interference from other Wi-Fi access points or non-Wi-Fi radio systems operating on overlapping frequency bands can adversely affect access point performance. Therefore, it is essential to conduct a thorough site survey and implement careful channel planning across the sites.

• Centralized Management

  • To effectively manage a network comprising a large number of APs deployed across the city, a centralized WLAN controller is necessary. This will facilitate streamlined administration, monitoring, and maintenance of the network.

Why Choose Altai

• Super Wi-Fi Coverage by Altai Smart Antenna Technology

  • Thanks to Altai’s patented antenna design and advanced signal processing algorithms, the Altai solution effectively addresses significant Wi-Fi bottlenecks and enhances uplink performance in non-line-of-sight (NLOS) environments. This optimization reduces the number of access points required, thereby lowering both capital and operational expenditures.

• Long Range Wireless Bridge

  • The Altai Super Wi-Fi solution enables access points (APs) to connect over distances of hundreds or even thousands of meters. This stable and robust wireless link supports high traffic volumes while minimizing the number of AP nodes, resulting in decreased capital and operational costs.

• Secured Wi-Fi

  • Altai’s solution ensures security for both wireless and wired links. Wi-Fi traffic data is secured using WPA2/WPA3 encryption. These data traffic is guarded by sophisticated CheckPoint Next-Generation Firewall (NGFW) embedded in a network controller. It automatically identifies and blocks malicious users or applications.

• Made for Industrial Grade Solutions

  • Altai’s access points are built with durable hardware designed to withstand outdoor weather conditions, ensuring uninterrupted 24/7 operation.

Application – 1) Public Wi-Fi

The complex layout of urban environments, characterized by numerous streets and alleys, corridors. Such a non-line-of-sight environment poses challenges in providing comprehensive Wi-Fi coverage as radio frequency signals experience significant loss during propagation. As a result, the deployment of public Wi-Fi will primarily occur in hotspot modes in high internet traffic areas such as parks, town squares, and tourist attractions.

It is recommended to install Altai access points (APs) on high ground like building rooftops, lamp posts, with adjustable down-tilt antenna to shoot to the target coverage areas. The APs can be interconnected via wired or wireless backhauls to incorporate into a MAN for Internet access. To provide coverage within public transport, Customer Premises Equipment (CPE) can be installed as a wireless anchor with 5GHz wireless backhaul to the network infrastructure, and at the same time providing Wi-Fi connectivity onboard for passengers.
