Increasing customer loyalty

Virtually everyone today has at least one wireless mobile device, like smartphones, tablets, and laptops computers. Yet, yesterday’s hotspot gateways can no longer handle the exploding amount of wireless mobile devices that need Wi-Fi access. To satisfy this fast-growing demand, hospitality businesses need a solution that can provide greater Wi-Fi bandwidth, capacity and performance.

The Zyxel UAG2100 is a next-generation wireless hotspot/access gateway that provides better performance, capacity, and service quality than other similar solutions. Its 802.11 a/b/g/n dual-radio(2.4 GHz and 5 GHz) design provides 2x the spectrum and 2x the bandwidth to accommodate a much larger amount of wireless devices. Its high performance hardware architecture can support 100 concurrent logins by default, and up to 200 concurrent logins via license upgrade. It also offers granular bandwidth management capabilities to enforce equal bandwidth sharing, avoid bandwidth abuse, and provide the service quality necessary to increase customer loyalty and attract new customers.

Generating revenue

The Zyxel Unified Access Gateway is designed with advanced billing, user authentication, and access control features that help hospitality businesses manage guest accounts, block unauthorized access, and generate revenue with their Internet services. It gives hospitality businesses the flexibility to offer Wi-Fi access as a free service, a tiered service (premium when a purchase is made), or a paid service, depending on the preferred business model.

  • Guest account management: Featuring a built-in account generator and a Web-based authentication portal, the UAG2100 helps hotspots provide controlled network access to guests with ease. Simply by entering the provided account information in the captive portal, guests can get secure wired or wireless access to the Internet in a matter of seconds. Additionally, the UAG2100 supports external RADIUS servers and external portal page redirection for added deployment flexibility.
  • Billing system: Hotspots can create up to 10 pre-paid billing plans with the UAG2100. Billing plans can be customized with varying bandwidth speeds, service duration, and level of payment.
  • SP350E Service Gateway Printer: The SP350E and UAG2100 combination is the perfect solution for Wi-Fi hotspot applications. The SP350E enables one-click billing and account generation, which offers easy operation for staff members and smooth services flows in hotel lobbies, conference rooms, waiting areas and busy restaurants and cafés.
  • SMS ticketing: The UAG2100 supports SMS ticketing with ViaNett* to provide improved convenience for both the business owner and the customer. With support for SMS ticketing, the UAG2100 allows business owners to send Internet account and billing information directly to the customer’s mobile phone, without needing to spend loads of money building an independent SMS ticketing system. This feature offers a cheaper and more environment-friendly ticketing solution compared to paper ticketing, and reduces the inconvenience related to customers loosing or forgetting paper tickets.
    *UAG2100 SMS ticketing support is by license

Meeting the challenges of future audit

To address information security concerns, hospitality businesses are sometimes required to retain Internet usage records for a certain amount time; and this can become a significant burden for the businesses without the right equipment. Designed with the hospitality industry in mind, the Zyxel UAG2100 helps the businesses resolving the challenges. With a syslog server built-in, the UAG2100 can automatically record user account information, MAC addresses, source and destination IPs, data volume and protocol types for future auditing requirements.
