Huawei WLAN over CATV Solution for Hotels Issue V1.0 Date 2013-01-08 Huawei Technologies Co., Ltd.
Huawei WLAN over CATV Solution for Hotels Background Smart mobile terminals have developed very fast in recent years. Users, therefore, are demanding more mobile Internet services including mobile offices, forums, micro-blogs, and e-commerce applications. Therefore, when choosing the hotels, many people prefer the ones provide wireless access. To meet this demand, the hotel industry is undergoing changes in the way it provides Wi-Fi connection to attract customers. However, many hotels encounter the following difficulties deploying wireless (WLAN) service. Large signal attenuation and poor indoor signals Access Points (APs) are usually distributed along hotel corridors. Signals have to pass through walls to reach inside guest rooms which decreases signal strength by 15 db to a very weak 25 db. Therefore, signals inside guest rooms are weak and unstable, degrading user experience. Difficulty in cable deployment and high cost of remodeling Wall drilling and recabling are necessary regardless of whether an indoor settled AP or a distributed AP is installed. Some old hotels even require renovation which is costly and affects business operations. Costly deployment Signal coverage may be improved if each room has an AP installed but APs greatly interfere with each other and occupy limited bandwidths. Moreover, complexities in indoor installation increase the capital expenditure (CAPEX). So, the WOC (WLAN Over CATV) solution which exploits existing CATV cable resources is developed to provide Wi-Fi service in the hotels. Combined with WOC products and advanced WLAN systems, the Huawei WLAN Over CATV solution provides high-quality wireless networks for hotels.
Solution This WLAN Over CATV solution is implemented in the following way: 1. 2.4 GHz signals of APs and cable TV signals are transmitted to a combiner deployed on the corridor or in the equipment room. Mixed WLAN/CATV signals are generated. 2. These mixed WLAN/CATV signals are then forwarded to a WOC panel in each guest room through existing TV cables. 3. Inside each room, the mixed signals are separated using a WOC panel. 4. WLAN signals are then transmitted through small antennas on the panel to mobile terminals, while the CTAV signals are transmitted to televisions. In this way, hotels can provide both Internet services and TV programs.
Benefits to Customers Strong wireless signals and wide signal coverage The WOC solution uses existing TV cables to transmit signals, causing no wall penetration signal loss. Signals are evenly distributed without coverage holes. Tests have shown that the WOC solution provides higher quality indoor signals than a common wireless deployment solution. Ease of implementation and low deployment cost No wall drilling or extra cabling is required. Working with WOC devices, a single AP can extend signal coverage to up to eight rooms. Stable signals and zero interference When signals are combined, CATV signals work at the 860 MHz frequency band and do not interfere with WLAN signals. And each AP manages signals in several rooms without interference from neighboring APs.
