A precision structural parts factory in Shenzhen, after deploying 80 APs…
An enterprise in Fuyong, Bao’an District, that makes metal components for consumer electronics expanded by two buildings last year, bringing its workshops and offices to nearly 12,000 square meters. IT manager Zhang initially had the construction crew follow the old approach of running ceiling-mounted APs along the ceiling. On day one, workers in the workshop downstairs could not open the MES barcode-scanning tool at their stations, video conferences in the second-floor office area stuttered constantly, and a remote factory audit by an international client turned thoroughly embarrassing. Zhang later came to us. We have heard plenty about “14 years focused on enterprise IT,” but what truly convinced him was a line in the site survey report: signal overlap in the original design exceeded 37%, co-channel interference caused clients to switch and roam constantly, and actual throughput was only 1/4 of the nominal value. After re-planning channels, adjusting AP locations, and adding 26 wall-plate APs, the factory’s WiFi packet loss rate dropped from 8.6% to under 0.3%. This story is a true microcosm of WiFi deployments at many manufacturing enterprises in Shenzhen.
Why Shenzhen Enterprises Choose Siwenlide for Enterprise Wireless WiFi Deployment
Siwenlide was founded in Beijing in 2011 and now operates from Beijing’s Airport Economic Core Area, serving more than 300 enterprise clients across manufacturing, technology companies, hotel chains, and industrial parks. Serving Shenzhen clients remotely is not a side business we picked up on a whim; it is a standardized service backed by a complete delivery system. Before signing a contract, we send engineers on site to conduct a wireless environment survey, produce heat maps, mark interference sources, and then issue a formal AP quantity and channel plan — rather than quoting a number off the top of our heads.
- On-site surveys come first; we reject the crude logic of “pricing by square meter.” Wall materials, equipment room locations, and the density of nearby WiFi and Bluetooth devices differ from building to building; placing an AP one spot off can collapse signal quality across an entire workshop. We must provide a formal heat map document before delivery.
- Transparent equipment selection, with a list of partner brands. We primarily recommend Huawei, Ruijie, and TP-Link commercial lines, combined flexibly according to budget and performance requirements. Free replacement for non-human damage during the contract period is a standard commitment of our Network Equipment Package service.
- One deployment, long-term stability. After deployment we provide wireless optimization services, including channel adjustment, power calibration, and client roaming policy configuration. Subsequent network changes (new workstations, added floors) enjoy existing-customer pricing.
What We Have Done in Shenzhen
Case 1: A software company in Nanshan Science Park, 150-person office area. A two-story loft layout mixing open workstations and private offices; the original 8 APs had such chaotic channel planning that the 5GHz band was nearly unusable. We surveyed signals across every floor with Ekahau and re-planned a reuse strategy for channels 1/6/11, steering 2.4GHz and 5GHz separately — phones and IoT devices on 2.4GHz, office laptops and video conferencing equipment locked to 5GHz. After optimization, concurrent clients in the same area went from stuttering at 60 devices to running stably at 180. The client had planned to spend RMB 80,000 on new APs; we solved the problem with a redesign plus 3 additional devices, for less than RMB 23,000.
Case 2: A chain business hotel in Longhua, 180 guest rooms plus public areas. Hotel WiFi is a hotspot for bad reviews, and guest complaints centered on full signal in the corridor but a dropped connection once inside the room. The root cause was not too few APs, but transmit power set too high on the wall-plate APs at each guest room door, which kept devices in neighboring rooms connected to the corridor AP and made signal plummet after the guest entered the room. We lowered the transmit power of the wall-plate APs from 100mW to 20mW, enabled client roaming steering, and added 2 high-density ceiling APs in the corridors to carry public-area traffic. After the fix, the WiFi rating on Ctrip rose from 3.8 to 4.5, and guest complaint tickets fell 78%.
Core Deliverables of Enterprise Wireless WiFi Deployment
What we deliver is not a construction job that ends once the cables are run and the APs connected; it is a complete wireless network solution. Every item below comes with corresponding documentation and acceptance criteria:
- On-site wireless environment survey report: signal heat maps over building floor plans, an interference source inventory (microwave ovens / Bluetooth / ZigBee devices), client density assessment, and recommended AP quantities.
- Wireless network architecture design: channel planning (2.4GHz and 5GHz allocation strategy), SSID segmentation (separate employee / guest / IoT networks), VLAN isolation plan, and wired backbone recommendations.
- Equipment installation and commissioning: precise AP placement (accounting for ceiling height and metal duct obstruction), fine channel tuning, transmit power calibration, and PoE switch port planning.
- Roaming optimization configuration: deployment of 802.11k/v/r, tuning of inter-AP handover thresholds to ensure video conferences stay connected while moving and barcode scanners do not lose orders.
- Security hardening: Portal authentication or 802.1X access control, WPA3 enterprise-grade encryption, physical isolation of the guest network, and retention of network access behavior logs.
- Acceptance testing and documentation handover: speed tests with iPerf, roaming entry/exit tests with WiFi Magic Box, and complete as-built documentation including equipment lists, IP planning tables, and follow-up maintenance contacts.
Pricing Reference (Shenzhen)
The pricing below includes equipment costs, installation and commissioning, and first-year after-sales support, but excludes structured cabling (please request a separate assessment if cabling is required). Prices are based on mainstream Huawei / Ruijie / TP-Link commercial lines; the final selection is confirmed according to the scenario and budget. All projects support installment payments or can be included in an IT Operations Outsourcing contract. For details, contact the Siwenlide Shenzhen business contact.

Frequently Asked Questions
Q: Many buildings in Shenzhen already have property-managed WiFi. Do we still need to build our own network?
A: Public WiFi offered by property management is usually a shared uplink, with dozens of businesses on a single broadband line and no security guarantees. The core value of an enterprise-owned WiFi network lies in smooth access to internal systems (ERP/MES/file sharing) and in isolating guest traffic from the internal network. With your own network, uplink bandwidth can be planned independently and is not affected by neighboring tenants.
Q: Factory workshops contain a lot of metal equipment and WiFi signals attenuate badly. What can be done?
A: Metal environments are indeed the natural enemy of WiFi. There are several approaches: first, increase AP density while lowering the power of each unit so signals need to penetrate less distance; second, prioritize the 5 GHz band (shorter wavelength, relatively lower penetration loss); third, use wall-plate APs installed flush to reduce diffuse reflection of signals in the air. The specific plan must be determined after an on-site survey.
Q: After deployment, can we manage the network ourselves?
A: Yes. Mainstream AC controllers support management through a web interface and a mobile app. Siwenlide provides basic training at handover, teaching your IT staff to handle routine monitoring, password changes, and simple troubleshooting. If you would prefer a hands-off approach later, you can also place your network equipment under our managed service as part of the Network Equipment Package, with free maintenance during the contract term.
Q: Our existing APs have poor signal. Can we optimize them without purchasing new equipment?
A: Yes. We begin with a survey and assessment. If the existing equipment still performs adequately (no severe aging), optimization mainly involves channel adjustment, power calibration, and roaming policy configuration. In some cases, adding a few wall-plate APs is enough, and a full replacement is not necessarily required. After an on-site diagnosis we will give you clear recommendations.
