Basement Signal Improvement Enhancing Signal Coverage in Dead Zones

Solution

What can you do when you have no signal in the basement, elevators, or high-rise buildings? Are there any recommended alternatives aside from expensive signal boosters? Due to the concrete structures and metal obstacles in parking garage basements, and the enclosed spaces in elevators, most network signals are blocked. In certain urban areas, buildings that are 20 stories or higher, or in areas where telecommunication providers have weaker signals in non-metropolitan regions, reception can be poor even on floors above the 15th.

Wi-Fi signal has become weaker, possibly due to uneven coverage, resulting in some areas experiencing slow internet speeds and disconnections. As the scale expands, extending the Wi-Fi network can become troublesome, requiring additional equipment and configurations. In multi-level underground parking lots like this one, management and maintenance can become complex, necessitating appropriate management tools and dedicated personnel.

This case is located in the basement levels B1 and B2 of an office building, where the Wi-Fi signal is weak, making it difficult to make phone calls, and mobile signals may be blocked. This directly impacts users, making it impossible to use mobile phones, tablets, and other devices for internet access, access online services, and emergency contact features. It also hinders remote monitoring of electric vehicles. To address this issue, Z-COM assists in resolving indoor signal coverage problems in parking garages by using enterprise-grade wireless controllers to manage wireless access points, meeting the demand for high bandwidth and low latency, thus resolving the issue of weak wireless network signals in such unique environments.

Features

Access Points: Enterprise-grade wireless network equipment, all of which have obtained NCC certification.

Deployment

Once the enterprise decided to buy in Z-COM’s solution, Z-COM will start on-site measurements to understand the basement's structure, area, existing signals, and the situation of the community telecommunications room to ensure the stability and speed of the wireless network. Whether it's a large, medium, or small community building, or a commercial office, luxury residential facility, network planning can be carried out based on the on-site situation and requirements. In this case, the existing network was extended using the existing pipeline wiring configuration, with internal data protected by a firewall. 

Achievement

After connecting to the internet, Wi-Fi Calling was tested for voice calls throughout the entire B1 basement area. Clear calls could be made when walking around, whether it was for landline or mobile phone calls. The flexible, seamless network roaming environment allows you to enjoy the same network speed in every corner of the community. It features seamless roaming, no packet loss, and no stuttering, with the ability to switch to the best signal at any time. Even under limited user bandwidth conditions, the network speed complies with traffic control. Z-COM helps you establish a stable Wi-Fi network in various environments, achieving extensive indoor signal coverage. Please feel free to inquire for more information!
