Internet & Wi-Fi Coverage

We provide multi-path internet across Shenzhen and Hong Kong, and we are a full-service China Mobile agent and a China Unicom fixed-network agent, so dedicated access with redundant paths is core business rather than a sideline. We have designed and delivered dedicated internet and wireless coverage for several dozen hotels in Shenzhen.

Wireless coverage — with tablets, phones and laptops everywhere, Wi-Fi is no longer an amenity in a hotel but part of the service. A hotel deployment has to satisfy six requirements:

Full coverage of every guest room with no dead spots; reuse of the existing cabling with 86-type wall-plate access points rather than new trunking; headroom for future guest authentication methods such as web portal, SMS and WeChat login; seamless roaming so devices switch access points without dropping the session; discreet hardware that supports PoE so no additional power cabling is needed; and centralised management with live monitoring of every access point.

Design — an AC controller with fit access points is used throughout. In the lobby, where obstructions are few, a ceiling access point covers 20 to 30 metres in diameter, so a small or medium hotel needs two or three units and a large lobby proportionally more. Restaurants are treated the same way, with access points distributed evenly across the floor. Guest floors use one access point per room cluster, mounted in the existing wall box.

Why this design works: professional antennas with linear transmit power adjustment let each area be tuned rather than over-powered; fit access points sharing an SSID give fast layer-2 roaming within a VLAN; 802.11ac dual-band units deliver up to 1200 Mbps with more concurrent clients; MAC and portal authentication can be combined with external portal and RADIUS servers to support SMS and WeChat login; 86-type wall plates with 802.3af PoE replace existing network sockets without redecorating; and the AC controller discovers and manages every access point from one console.

We size routers, switches, PoE equipment, access points and controllers to the property, then hand over documentation covering cabling, SSID and VLAN design, IP plan and acceptance test results.
