Hangzhou Clothing Wholesale Mall, a prominent commercial building, sought to upgrade its existing PSTN telephone system to a VoIP network telephony system. The primary objectives of this transformation were to significantly enhance communication efficiency and elevate user experience.
The customer had several initial concerns:
● Compatibility issues with network equipment.
● Poor audio and video quality.
● Lengthy construction periods and high associated costs.
After rigorous on-site testing by the quality inspection team and project engineers, the customer was convinced of the efficacy of Ourten's OT-PLC302-N two-wire transmission solution. This solution was selected for its ability to enhance the effectiveness of the network intercom system, resulting in substantial time and cost savings.
The customer's concerns included:
● Network Compatibility:
VoIP networks employ various protocols, creating potential incompatibilities such as unsynchronized audio and video streams, call latency, and lost control commands when using diverse transmission solutions.
● Audio-Video Quality:
Over long transmission distances, bandwidth limitations could cause interruptions in HD video streams, including frame freezing and reduced image quality.
● Construction and Cost:
Re-cabling with optical fibers or Ethernet cables would greatly extend the construction timeline, disrupt mall operations, and significantly increase cable procurement and labor costs. The mall management needed a highly feasible solution.
Based on a similar successful PSTN-to-VoIP upgrade project at Wanda Plaza in Nanjing, Ourten's OT-PLC302-N solution was recommended. Subsequently, joint testing was carried out on-site with technicians from all parties involved.
Through rigorous evaluation, the customer identified three major advantages of Ourten's solution:
● Transparent Transmission:
The network transmitter provides transparent TCP/IP compatibility, is plug-and-play, easy to install, and can be managed by non-technical staff.
● High-Quality Transmission:
Utilizing existing two-wire telephone cables, the OT-PLC302-N reliably transmits 100Mbps data over distances of up to 600 meters. It ensures minimal latency and maintains smooth audio-video streams.
● Reduced Construction Impact:
Eliminating the need for extensive re-cabling reduced construction times dramatically. Installation involved merely adding transmitters and minimal cable connections, cutting down cable and labor costs by 45%. Merchants continued operations uninterrupted, significantly simplifying project implementation.
By adopting Ourten's OT-PLC302-N network transmitter, Hangzhou Clothing Wholesale Mall achieved a notable cost reduction of 45%, while also generating 4 tons less waste compared to traditional methods. Mall operations remained unaffected throughout the upgrade, fully meeting the project's intended design and performance goals.
