If a hotel WiFi solution is only from the perspective of an equipment supplier, the content usually stays at the level of “which APs were used, which areas were covered, and how high the specifications are.”
However, anyone who has actually delivered hotel wireless projects knows that the hardest part is never simply installing the devices. The real challenge is to build a wireless network system that can operate stably for the long term in a hotel that remains open for business, without disrupting operations, damaging the decoration, or leaving hidden risks behind.
The project we are delivering this time is the WiFi coverage project for Bangkok Chao Phraya Courtyard Hotel.
We are the local implementation team for this project, responsible for site survey, detailed design, AP placement planning, construction coordination, device installation, network optimization, testing, acceptance, and maintenance recommendations after handover.
1. Bangkok Hotel WiFi Project Overview and On-Site Implementation Background

Project Goals
The hotel owner did not simply ask us to “install WiFi.”
They made several practical project goals very clear from the beginning:
First: the guest room network had to work well inside the room, not just show a strong signal in the corridor.
Second: key public areas such as the lobby, restaurant, and meeting rooms had to remain stable during peak usage periods.
Third: the construction process could not heavily interfere with normal hotel operations, especially front desk service and room sales.
Fourth: the front desk, billing, office, and CCTV networks had to be separated from the guest internet network.
Fifth: the project had to be easy to maintain after handover so that the hotel’s own maintenance staff could understand and manage it efficiently.
From the moment we accepted this project, we knew this was not just a “hotel with a few APs installed.” It had to be delivered as a true commercial-grade hotel wireless network project.
2. Real Hotel Network Problems We Identified After Entering the Site
Before the hotel appointed us, there had already been some complaints about the network experience.
These were not “the WiFi is completely down” type problems. They were the more difficult kind of issues that damage guest satisfaction, are easy to ignore by non-engineers, and are very common in hotel WiFi projects.
2.1. Inconsistent Guest Room Experience
On the same floor, some rooms were considered acceptable by guests, while others frequently received complaints about slow video loading and unstable video calls.
From an engineering point of view, this immediately suggested that the previous coverage logic was not based on a consistent, controllable in-room design. It was more likely relying on extended signal from shared areas.
2.2. Unstable Experience in the Lobby and Front Desk During Peak Hours
At check-in peaks, the front desk area sees many smartphones connecting at the same time. Guests open booking emails, refresh maps, upload passport information, and contact travel companions.
If wireless resources around the front desk are not properly planned, users may still appear connected but actual internet access becomes noticeably less smooth. Even worse, if the front desk business systems are not isolated from guest traffic, the operational systems can also slow down.
2.3. The Restaurant and Meeting Areas Were Typical “Fine When Empty, Problematic When Busy” Zones
The biggest challenge in dining areas is not continuous heavy traffic all day long. It is short bursts of dense simultaneous access.
The same is true for meeting rooms. When empty, everything may look fine. But once a training session, presentation, or small meeting starts, dozens of devices may connect within minutes.
2.4. Roaming Gaps Existed in Transition Areas
When guests left their room, walked to the elevator lobby, and moved down to the lobby or restaurant, the connection was not always smooth.
Typical symptoms included:
Devices hesitating to roam at the room entrance
Short service drops near the elevator lobby
Signal still appearing present, but application performance getting worse
2.5. Outdoor Areas Had Barely Been Properly Planned
The pool and terrace area had previously been in a “borrow a little indoor signal if possible” state.
This may seem acceptable at first glance, but once guests actually spend time outdoors, the experience becomes inconsistent, and indoor-to-outdoor roaming behavior becomes problematic.
2.6. No Clear Mapping Between Devices, Room Numbers, and Ports
For us as an engineering contractor, this is a classic maintenance risk.
If the hotel reports that “Room 608 has poor WiFi,” but the AP names, switch ports, and room number records do not correspond clearly, later troubleshooting becomes slow and costly.
3. Why This Hotel WiFi Project Required a Full Engineering Approach
One of the biggest misunderstandings in hotel WiFi projects is this:
If the property does not look very large, people assume it does not need a serious design.
In reality, medium-sized hotels like this one are exactly the kind of project where problems appear most easily. The reasons are simple:
There are many rooms, but the budget is usually not as generous as in a large luxury hotel
The hotel remains in operation during construction, so installation windows are fragmented
The property serves both independent travelers and meeting groups, so traffic patterns change significantly
The decoration is already complete, so rough construction is not acceptable
The hotel does not have a full-time IT team, so post-project maintenance must be simple
In other words, this kind of project cannot be handled like a large luxury hotel with over-engineered redundancy, but it also absolutely cannot be treated like a small guesthouse with a few random APs.
It requires a design that is structurally clear, cost-conscious, and truly deliverable.
That is why the principles we set were very clear:
Every guest room must have its own AP
Public areas must distinguish between main coverage and supplementary coverage
Outdoor areas must be designed independently
A centralized management core is required
PoE centralized power supply is required
Network isolation must be implemented
The project must be handed over with a complete maintenance framework
4. COMFAST Device Selection Based on Real Hotel Deployment Requirements
Why we used a specific device in a specific area, instead of another one.
4.1. Core Management Device
COMFAST CF-AC100, 1 unit
In this project, this device is not simply “what gets the internet working.”
It serves as the unified wireless management core for the entire hotel network.
We needed it for:
Centralized AP management
Device status monitoring
Unified wireless policy deployment
Group-based management
Rapid identification of problem devices during maintenance
Without this layer, 68 room APs, more than ten public area APs, outdoor APs, and transition APs would all operate separately, making future maintenance far more difficult.
4.2. PoE Switching Layer
COMFAST CF-SG181P, 4 units
We used 4 PoE switches not to make the equipment list look larger, but because centralized power and segmented access make the most sense in a hotel scenario.
The benefits are straightforward:
One cable handles both power and data
No scattered power adapters in rooms and public areas
Cleaner construction
Faster port-level troubleshooting
Easier area-based switch management
4.3. Main Public Area Coverage Devices
COMFAST CF-E393AX (AX3000 / WiFi 6 Dual-Band Ceiling AP), 9 units
These devices are the backbone of the public area network.
We deployed them in:
Main lobby seating area
Front desk waiting area
Breakfast area / restaurant
Meeting rooms
Multi-function hall
These areas share one common characteristic:
They are not just “open spaces,” but zones with concentrated users, bursty traffic, and high expectations for user experience.
That is exactly where a WiFi 6 dual-band ceiling AP makes sense.
4.4. Transition and Supplementary Coverage Devices
COMFAST CF-E385AC (AC1200 / WiFi 5 Ceiling AP), 2 units
We did not place these two APs in the core public areas. Instead, we specifically deployed them in:
Lower-floor elevator lobby / transition corridor
Upper-floor elevator lobby / transition corridor
These devices are best suited not for primary coverage, but for boundary fill-in and roaming transition.
If this layer is omitted, the user experience between the guest room and public area will often suffer.
4.5. Standard Guest Room Coverage Devices
COMFAST CF-E535N, 65 units
All 65 units were allocated to standard guest rooms.
The reason is simple: the largest number of rooms need stable, consistent, easy-to-install, and easy-to-maintain coverage, not unnecessarily high specifications.
4.6. Upgraded Devices for Higher-Level Room Types
COMFAST CF-E538AC V2, 3 units
Used for:
Executive Suite
Family Suite
VIP Room
These room types are larger, support more devices, and host guests who are more sensitive to WiFi quality.
If they were configured exactly like standard rooms, we would likely receive repeated complaints from these premium room types after opening.
4.7. Outdoor Coverage Devices
COMFAST CF-EW74 V2, 2 units
Used for:
Poolside area
Courtyard / terrace area
We deliberately avoided relying on indoor APs to “spill over” into outdoor areas.
In real projects, that shortcut always causes trouble later.
5. Hotel WiFi Network Topology Design for Stable Wireless Coverage
A hotel WiFi project cannot rely on AP deployment alone. A stable wireless system must start with a clear topology structure. In this project, our topology design follows a layered approach built around centralized management, segmented PoE access, room-by-room coverage, dedicated public-area coverage, transition-area optimization, and independent outdoor extension. The biggest advantage of this topology is that it keeps the whole hotel network organized, scalable, and easy to maintain. Guest room APs, public area APs, transition APs, and outdoor APs all connect back through structured PoE switching, while the CF-AC100 provides unified wireless management at the core. This makes it easier to control SSIDs, isolate traffic, optimize roaming, identify faults by area, and expand the network later without disrupting the original design. From an engineering perspective, this topology is far more reliable than a flat structure, because it reduces troubleshooting time, improves power and access management, and ensures that every functional area in the hotel can be managed as part of one complete hotel wireless system.
6. Guest Room WiFi Coverage Design for Better In-Room User Experience
6.1. Guest Room Areas
Guest rooms are the most critical part of the entire project.
We ultimately adopted a one-room, one-AP design, and not simply because “that is what the industry says,” but because the on-site conditions made it necessary.
Why Corridor APs Could Not Be Used as the Main Guest Room Coverage
During the site survey, we found that the room structure in this hotel was far from simple:
Room doors caused noticeable signal attenuation
Bathrooms contained mirrors and metal fittings
TV walls and wardrobes created shadowing
In some room types, the work desk was far away from the entrance
If we had used corridor ceiling APs to penetrate walls and cover multiple rooms, guests might still have been able to see the SSID. But the actual experience at the bedside and desk area would have been unstable.
This kind of solution may pass superficial testing, but once the hotel is fully operating, complaints would quickly begin.
How We Assigned Devices in Guest Rooms
65 standard rooms: CF-E535N
3 higher-grade room types: CF-E538AC V2
What We Focused on During Room Installation
The first point was wall box adaptation.
Many old wall boxes were not deep enough. If installed by force, the result would be long-term contact instability.
The second point was old cable screening.
We did not stop at “the link light turns on.” We identified and corrected unstable cable runs before installation.
The third point was AP-to-room mapping.
Every room AP was named according to the room number and recorded against the switch port in the project documentation.
The fourth point was room restoration.
After installation, the housekeeping team had to be able to return the room directly to service, with no obvious signs of engineering work left behind.
6.2. Lobby and Front Desk Areas
The lobby and front desk are the areas where WiFi problems are least acceptable.
Guests usually form their first impression of a hotel’s network right here.
Why We Used CF-E393AX
Because what this area needs is not just coverage, but peak-time carrying capacity.
During check-in peaks, the number of devices rises sharply in a short period. If the AP capability is not sufficient, the user experience degrades immediately.
Key Problems We Solved in This Area
Isolation between front desk business systems and guest traffic
Separate coverage for the front desk waiting zone and the lobby seating zone
Roaming optimization at the entrance and indoor boundary
A lightweight portal flow so guests do not confuse a slow page with a broken network
6.3. Restaurant and Breakfast Area
The breakfast area is one of the most typical short-term high-density zones in a hotel.
A stable experience during low traffic does not guarantee a stable experience during breakfast peaks.
What We Did in This Area
Used 2 CF-E393AX APs for segmented coverage
Avoided relying on a single AP to carry the entire restaurant
Avoided installation points near heavy electrical boundaries and unsuitable ceiling positions
Re-tested during actual breakfast hours instead of relying on empty-room speed tests
We particularly emphasize this point:
If the restaurant network only passes a speed test during a quiet afternoon, that result has very little practical value.
6.4. Meeting Rooms and Multi-Function Hall
Meeting areas are among the most underestimated zones in hotel WiFi projects.
That is because the behavior pattern of meeting users is very different from that of ordinary guests.
Common Scenarios in These Areas
Concentrated QR-code sign-in
Many devices connecting simultaneously
File downloads and synchronization
Wireless screen sharing
Video conferencing
Event live streaming and image uploads
Our Device Allocation for Meeting Areas
Meeting Room A: CF-E393AX
Meeting Room B: CF-E393AX
Multi-Function Hall: 2 × CF-E393AX
What We Specifically Addressed
We considered speaker zones and audience zones separately
We performed dedicated testing before events
We reserved policy space for a meeting-specific network
We prevented meeting traffic and ordinary guest traffic from being mixed together
6.5. Corridors, Elevator Lobbies, and Transition Areas
These are the most commonly neglected areas, but they are also the places where guests most easily feel that “the WiFi is not smooth.”
Why We Used 2 Dedicated CF-E385AC Units
Because these areas do not require high-density primary coverage, but they do require:
Smooth transition from room to public area
Elevator lobby coverage fill-in
Continuous floor transition coverage
If these zones are left untreated, the problems tend to appear exactly “when the guest leaves the room.”
Our Experience Here
Devices in transition areas should not aim for the widest possible coverage.
The real goal is to create a smooth boundary.
If the signal is too strong, these APs will start competing with room APs and public area APs for client connections.
6.6. Pool and Terrace Areas
For this area, we firmly refused to extend indoor APs and hope for the best.
Why CF-EW74 V2 Had to Be Used Independently
Because outdoor conditions are truly different:
High humidity
Direct sunlight
Rain exposure
Frequent indoor-to-outdoor roaming
What We Mainly Handled On Site
Outdoor mounting method
Waterproof sealing
Cable protection
Indoor/outdoor boundary optimization
Rainy-season follow-up recommendations
If people try to save time in this part during early installation, the future repair rate becomes very high.
7. Lobby and Restaurant WiFi Deployment for High-Density Guest Traffic
A hotel network must not only provide physical wireless coverage. It also has to be logically segmented.
This was one of the points we insisted on most strongly as the engineering contractor.
We ultimately planned the following network logic:
Guest WiFi: for hotel guests and visitors
Staff WiFi: for hotel employees
Front Desk / POS / PMS: dedicated business network
CCTV / IoT: surveillance and smart device network
Conference Network: temporary network for meetings and events
The reason is very practical:
Guest traffic must not affect front desk operations
Guest devices must not share the same environment as internal devices
Meetings and events must not compete directly with normal guest internet usage
Later troubleshooting becomes much easier when the fault domain is clearly separated
8. Meeting Room and Hall WiFi Design for Event Connectivity
One of the biggest challenges in hotel projects is that the building usually remains in operation during the work.
This hotel was no exception.
Our Construction Coordination Method
Scheduled work by floor and room status
Prioritized check-out / check-in gaps for room installation
Avoided check-in peaks and breakfast peaks for public-area work
Scheduled core switching during low-impact time windows
Cleaned and confirmed each work area with hotel management at the end of every day
Why This Matters
Because hotel engineering is not just about technology. It is also about service continuity.
If construction coordination becomes chaotic, the project will not be considered successful by the hotel, no matter how good the technical result is.
9. Corridor and Transition Area WiFi Coverage for Smooth Roaming
We do not use “the phone shows full bars” as an acceptance standard.
A real hotel WiFi project must be tested according to actual usage scenarios.
Our Optimization Focus
Bedside, desk, and inside door positions in guest rooms
Lobby check-in peak simulation
Breakfast peak testing in the restaurant
Multi-device access testing in meeting areas
Transition testing from room to corridor and elevator lobby to lobby
Indoor-to-poolside boundary testing
Our Acceptance Focus
Whether all APs were online and identifiable
Whether room numbers matched device naming
Whether switch ports and APs were traceable
Whether Guest and internal business networks were effectively isolated
Whether real application experience in critical areas was stable
10. Outdoor Hotel WiFi Coverage Design for Pool and Terrace Areas
At handover, we did not simply give the hotel the equipment.
We handed over a complete maintenance logic as well.
Documents We Required for Delivery
Equipment list
Room-to-AP mapping table
Public area AP location table
Switch port mapping table
Network logic allocation table
Management account table
Construction change log
Outdoor maintenance notes
What We Recommended for Ongoing Maintenance
Check AP online rate once every week
Spot-check key room types once every month
Perform dedicated checks before every meeting or event
Inspect outdoor APs before and after the rainy season
Troubleshoot in the order of “room number / area → AP → switch port → link status”
The value of this method is that hotel staff no longer have to rely on guesswork.
There is a clear troubleshooting path.
11. Network Isolation and Construction Management for Reliable Hotel Operations
If I had to summarize only the most important lessons from this project, I would highlight the following points.
First, hotel guest rooms must use one AP per room. Corridor APs cannot be treated as the main room coverage layer.
Second, public areas must distinguish between main coverage and supplementary coverage. One AP type cannot do everything.
Third, outdoor areas must always be designed independently. Do not force indoor APs to serve outdoor spaces.
Fourth, centralized management and a PoE switching layer are not optional extras. They are the foundation of long-term maintainability.
Fifth, network isolation must be designed from the start. Do not wait until problems appear.
Sixth, what should be handed over is not just the network, but also the records, mapping tables, maintenance logic, and fault-handling workflow.
12. Hotel WiFi Project Acceptance Testing and Long-Term Maintenance Planning
As the local WiFi engineering contractor for this project, our biggest concern was never simply “how many devices were used,” but whether this network could truly support hotel operations and guest experience in the long run.
COMFAST, in this project, was the equipment supplier.
Our responsibility as the implementation team was to turn those devices into a Hotel WiFi Coverage Solution that could actually be deployed, accepted, and maintained.
In the end, this project used:
With this equipment system, we completed full coverage across guest rooms, public areas, transition zones, and outdoor spaces, while also putting construction coordination, network isolation, optimization, acceptance, and maintenance workflow in place.
