Late last autumn, a manufacturer of automotive components in Xindu District, Chengdu approached us. Its workshop covers more than 8,000 square meters and its production lines run around the clock, with workers scanning codes on tablets to report their work. But the WiFi signal kept dropping in and out, and the scanners were forever “spinning.” Our engineers went on site to investigate and found that the root cause was not too few APs: placement had been decided entirely by gut feeling, channel interference was severe, and endpoint roaming policy was simply nonexistent. Once on site, we re-planned the locations of 23 APs, added channel isolation, and deployed industrial-grade roaming optimization. Two weeks later, the scan success rate reached 99.2%, and the workshop manager finally stopped fielding complaint calls every day. That project later became our opening story whenever we introduce wireless upgrades to manufacturing clients in Chengdu.
Why Chengdu enterprises choose Siwenlide for enterprise wireless WiFi deployment
Wireless networking is one of those things that is neither a big deal nor a small one. Once an enterprise reaches a certain scale, wireless becomes a production tool — employee devices, guest devices, IoT sensors, and industrial PDAs all depend on WiFi to function. Uneven coverage, roaming dropouts, exposed security issues: any one of them can give the IT department a headache for days. Siwenlide has been providing enterprise IT Operations Services since 2011, and we have paid plenty of “tuition” in the wireless space, watching far too many enterprises get burned by low-cost solutions and then come back to us for rework.
- Frontline experience is not just talk. 80% of our engineering team hold H3C or Huawei wireless certifications. Over the past three years alone, we have delivered 47 enterprise wireless projects in the Chengdu area, spanning manufacturing plants, hotel chains, and coworking spaces — and the pitfalls we have run into far outnumber anything written in a proposal.
- It is not just installing APs — it is end-to-end delivery. Many integrators sell the equipment and walk away, leaving behind a maintenance number nobody answers. We commit to a one-stop service covering site survey, solution design, deployment and implementation, and ongoing operations and maintenance, with free replacement of equipment during the manufacturer’s warranty period and a response time of 4 hours.
- Security and compliance are assured. Enterprise wireless is not just a matter of installing a router. Siwenlide’s delivery packages come standard with WPA3 enterprise-grade encryption, guest network isolation, and log auditing, meeting MLPS 2.0 (China’s Multi-Level Protection Scheme) and internal compliance requirements.
What we have done in Chengdu
An internet company with 200 employees in Jinjiang District, Chengdu occupies two floors. Its original wireless setup consisted of consumer-grade APs installed casually during a renovation three years earlier. Employees complained constantly about laggy video conferences, and three successive IT managers failed to solve it. The first thing we did after taking over was a heat-map survey — which revealed that AP density in the meeting rooms was far too high, while the open office area actually had three dead zones. After re-planning, we used 18 commercial-grade APs, carried out channel frequency planning, and deployed a unified management platform. Now the company’s IT manager tells us, “Our employees used to start every meeting with ‘wait, let me reconnect to the WiFi.’ That sentence is gone now.”
Another case is a hotel chain in Pidu District, Chengdu, with 320 rooms across guest rooms and public areas. Years earlier each floor had a single ceiling-mounted AP, so guests had full signal in the corridors but dropped to one or two bars once inside their rooms. Negative reviews mentioning poor WiFi accounted for 30% of the hotel’s OTA ratings. After our research, we proposed a split architecture: add wall-plate APs inside guest rooms, keep ceiling APs in public areas, enable seamless roaming across the entire network, and use portal + WeChat Mini Program authentication. Three months after the change, the hotel’s rating rose from 4.1 to 4.5 and WiFi-related complaints fell by 78%. That approach was later replicated at their branches in Mianyang and Deyang.
Core deliverables of enterprise wireless WiFi deployment
- On-site survey and wireless heat-map planning. This is not about glancing at a floor plan and placing an order on a hunch. We use professional instruments to measure signals, identify interference sources, and produce heat maps, so the position, angle, and channel of every AP are calculated.
- Commercial-grade equipment selection and supply. We choose the right AP for each scenario — dual-band ceiling units for offices, IP67-rated panels for industrial plants, wall-mounted units for hotel chains. Brands are mainly H3C, Huawei, and Ruijie, with models matched to project requirements: no inflated specs and no filler.
- SSID architecture and VLAN isolation design. Employee networks, guest networks, and IoT device networks run separately, each with its own security policy. This eliminates the sloppy practice of one password shared across the whole company.
- Seamless roaming optimization. Endpoint handover latency between APs is kept under 50ms, delivering a genuine “no disconnection while moving” experience. In factory workshops, hospital corridors, and hotel lobbies, this metric directly determines the user experience.
- Wireless security hardening. WPA3 enterprise-grade authentication, 802.1X access control, guest portal authentication, and 180-day log retention — meeting MLPS requirements and internal corporate security audit standards.
- Operations platform handover and training. We hand over a unified network management platform where AP status, connected endpoint counts, and traffic reports are all clearly visible. We also provide two hours of on-site training so your IT staff can handle basic operations and maintenance independently.
Pricing reference (Chengdu)
The cost of a wireless deployment is driven mainly by three things: area, endpoint density, and feature requirements. Below is a reference range for an entry-level tier; an accurate quote requires an on-site survey.
| Scale tier | Typical area | Reference AP count | Includes survey / deployment / one year of maintenance |
|---|---|---|---|
| 50 – 100-person office / plant | 800 – 2000 m² | 12 – 25 units | RMB 48,000 – RMB 85,000 |
| 100 – 300-person office / mixed-use site | 2000 – 5000 m² | 25 – 60 units | RMB 85,000 – RMB 180,000 |
| 300+ people / multi-floor / industrial environment | Over 5,000 m² | 60+ units | From RMB 180,000, quoted as needed |
The above are reference prices for the Chengdu area, tax included, excluding renovation or structural modification. All projects include a 3-year manufacturer’s warranty on equipment, with free replacement of failed parts during the contract term. If your scenario has special requirements — such as ceiling-mounted dust protection for a cleanroom, or interference-resistant industrial-grade APs for a factory — pricing will be adjusted accordingly. Feel free to call us to discuss your specific needs.
Frequently Asked Questions
Q: Our plant has a lot of metal equipment and WiFi signal attenuation is severe. Is there a way to solve this?
A: Metal environments are indeed the biggest obstacle for wireless signals. The standard approach is to increase AP density in areas with dense metal equipment and use industrial-grade high-gain antennas. If metal obstruction is too severe, you can also consider a cabling + feeder cable external antenna solution to extend coverage into signal dead zones. A steel structure factory in Qingbaijiang District, Chengdu did exactly this — after the upgrade, terminal speeds in the workshop went from 12 Mbps to 95 Mbps.
Q: How can guest WiFi be isolated from the internal network securely?
A: The standard practice is physical isolation — the guest SSID runs on a separate VLAN with its own egress, never touching the internal network’s Layer 3. If your company has MLPS 2.0 (China’s Multi-Level Protection Scheme) requirements, you can add 802.1X access authentication, forcing guest devices through portal authentication before joining the network, with logs retained for audit. Siwenlide’s solution follows this logic by default, at no extra cost.
Q: Will deployment disrupt normal office work?
A: Generally not. AP replacement can be done floor by floor or zone by zone, with new APs brought online and verified before old devices are shut down, and hot-switch windows scheduled outside working hours. If your company has special requirements, we can also work at night or on weekends — this would be quoted separately in advance.
Q: How fast is Siwenlide’s maintenance response? Do you have engineers locally in Chengdu?
A: We have resident engineers in Xindu District, Chengdu, with remote support and on-site arrival within 4 hours. Devices that fail during the maintenance period are replaced with new units — no repairs that leave customers waiting. If you have higher requirements for network security, you may also want to learn about our sTrust Zero Trust Security solution, which delivers wireless access and admission control as an integrated package.
