Technical Architecture Breakdown: Retail Malls & Shopping Outlets

Indoor 5G Offloading vs WiFi

Indoor 5G (C-band/mmWave) suffers ~28 dB attenuation loss through commercial concrete and Low-E glass. Enterprise WiFi handles over 70% of indoor mobile data, making seamless offloading via OpenRoaming mandatory for uninterrupted customer connectivity.

Hardware Integration: Cisco Meraki (MR Series)

Native cloud RADIUS & Hotspot 2.0 profile push via Dashboard API. Purple overlays with your existing access points in approximately 20 minutes without replacing firmware or deploying on-premise controllers.

无摩擦连接的基石

Purple 的使命是改善人们在现实世界中的连接方式。13 年来,我们一直朝着一个终极愿景努力:公共 WiFi 应该安全、无缝且无处不在。

创立这家公司的初衷是源于大众对繁琐的 Captive Portal 的普遍反感 - 也就是每个人在尝试连接 WiFi 时都讨厌填写的那些表单。Captive Portal 会带来阻碍,但它们仍然是行业标准。我们的新解决方案在提高安全性的同时,直接解决了这一阻碍,并保留了场馆价值。让我们来破除一些围绕无缝 WiFi 的迷思。

移动数据 误区:“移动数据 (4G/5G) 会让公共 WiFi 走向淘汰。”

事实:对 WiFi 的需求正在增加而非减少,这表明公共 WiFi 依然必不可少。

数据限制与成本:

认为“每个人都有无限流量”的看法往往局限于信息茧房。在英国,只有 13% 的移动套餐是无限流量的。许多电信运营商已经更改了他们的套餐,实施了公平使用政策,即使贴有“无限”标签,在达到设定的使用阈值后也会限制网速。

消费者的高需求

过去一年中,“免费 WiFi”和“我附近的 WiFi”的搜索量增长了 60%。80% 的人表示,他们会选择在提供高品质 WiFi 的场所就餐、消费或住宿。像 Booking.com 这样的网站甚至将 WiFi 质量列为专门的评分项。

5G 无法穿透室内

为了达到更快的速度,5G 使用了更高的频段。高频电磁波的波长较短,更容易被物理障碍物吸收或阻挡,这意味着室内用户很可能需要借助 WiFi 才能访问互联网。

高密度覆盖失效

在体育场馆或市中心等人员密集的喧闹环境中,移动网络覆盖通常较差,这使得公共 WiFi 变得至关重要。

安全与隐私误区:“无缝 WiFi 听起来像是一个开放网络;安全有保障吗?”

事实:通过证书实现企业级保护。

基于证书的安全防护

Purple 应用程序通过基于证书的安全机制提供军工级安全保障。与相当于开放网络且存在安全挑战的 WPA 共享密钥不同,Purple 解决方案是基于证书的。这涉及用户设备与 Purple 服务器之间的握手,以建立安全连接。

数据保护

为了确保数据保护,所有访客数据均在我们的服务器上进行加密,并根据不同国家的要求存储在不同的区域。我们符合全球所有主要的个人信息保护法规,包括 GDPR 和 CCPA。

场所数据误区:如果我们取消 Captive Portal,场所就会失去收集联系方式、向客户开展营销以及保持合规的能力。”

事实:我们可以通过选择和合规性来最大化获取高质量的数据。

数据最小化

我们遵循“数据最小化”原则,这是世界上几乎所有数据保护法案的核心基础。我们确保人们是自愿分享这些数据的。

无摩擦数据共享

这种基于应用程序的新方法消除了阻碍,从而获得了更高质量的数据。用户可以无缝连接到安全网络,然后会收到一条微小的通知,询问“您愿意分享您的数据以获取特别优惠和奖励吗?”。这种基于选择的方法使共享的数据量显著增加(超过20%),因为整个过程中的阻碍已被完全消除。

场所分析

场馆可以全面了解物理世界,这与用于数字资产的指标相当。分析数据包括:谁来过、频次如何、停留多长时间、新近度、频次、流失率和路径。

部署安装误区:“部署很复杂,会拖慢现有网络,并会让用户饱受弹窗折磨。”

事实:快速且毫不费力的部署

速度

设置极其简单。如果场馆拥有现有的企业级设备(Cisco, Meraki, Ruckus, Aruba),使用现有的指南,部署最快只需 30 分钟。该平台还可以部署在第三方 WiFi 设置之后,例如 Ubiquiti 接入点。

即插即用

对于没有接入点的人群,可以将 Purple Hub 插入路由器。Purple Hub 不会影响现有网速,因为它的功能是作为现有宽带提供商之外的网关。事实上,如果场馆使用 Purple 的 DNS 服务器,终端用户感受到的网速通常会提升,因为这些服务器比公共 DNS 服务器快得多。

弹窗

用户不会仅仅因为路过场馆就收到铺天盖地的弹窗。我们采用了一种延迟机制(因场馆类型而异),这意味着用户通常在某个位置停留5分钟、10分钟或15分钟后才会看到通知。在全市范围的部署中,用户在后台无缝连接,极少会看到弹窗,因为 Purple 非常清楚有必要尽量减少弹窗并保持弹窗的实际意义。

准备好体验无缝连接了吗?

Purple 专注于安全、无缝的 WiFi,消除了 Captive Portal 普遍存在的阻碍,同时增强了所有用户的安全性和无缝体验,并将 WiFi 作为一项公共事业提供给所有人。对于场馆而言,我们通过更强的客户意向帮助获取更高质量的数据。

常见问题

Why doesn't 5G replace the need for indoor public WiFi?

Indoor 5G cellular frequencies (particularly mid-band C-band and high-band mmWave) suffer severe attenuation losses of 25 dB to 35 dB when penetrating concrete walls, structural steel, and Low-E metallized glass. Enterprise WiFi handles over 70% of indoor mobile device data traffic, providing consistent coverage, high throughput, and localized digital engagement where cellular networks cannot reliably reach.

How is seamless Passpoint and OpenRoaming more secure than an open captive portal?

Legacy captive portals operate on unencrypted open SSIDs where client communications are vulnerable to Layer 2 eavesdropping and man-in-the-middle packet capture. Passpoint (Hotspot 2.0) and OpenRoaming utilize IEEE 802.11u and WPA3-Enterprise 802.1X certificate-based encryption (EAP-TLS), establishing an authenticated, cryptographically isolated tunnel for every connected visitor device.

How can venues capture marketing data without a traditional captive portal splash form?

Instead of forcing visitors through high-friction splash pages before granting internet access, seamless WiFi connects devices instantly in the background. Once safely connected, venues deliver a non-intrusive, choice-based prompt or push notification inviting guests to opt into rewards, VIP offers, and loyalty programs. This choice-based opt-in model increases verified marketing CRM capture rates by over 20% compared to forced forms.

Does transitioning to seamless Passpoint WiFi require replacing existing access point hardware?

No. Passpoint (Hotspot 2.0 Release 2) and OpenRoaming are open industry standards supported natively by enterprise wireless hardware from Cisco Meraki, HPE Aruba Networking, Ruckus Wireless, Juniper Mist, Extreme Networks, and Ubiquiti UniFi. Purple integrates via standard RADIUS, RadSec, and vendor cloud APIs, enabling automated profile provisioning in under 30 minutes without hardware upgrades.

How does seamless WiFi eliminate Apple CNA and Android captive portal pop-up timeouts?

Mobile operating systems run automated HTTP probes (like captive.apple.com or connectivitycheck.gstatic.com) when connecting to open networks, often resulting in stuck mini-browsers and failed redirects. With Passpoint, the device recognizes the network as secure 802.1X, bypassing the Captive Network Assistant entirely and connecting silently with zero user intervention.

How does seamless WiFi improve footfall analytics accuracy for retail and hospitality venues?

Because seamless WiFi automatically authenticates returning visitors upon entry without requiring manual logins, venues capture 100% of returning customer journeys. Systems like Purple correlate presence telemetry, dwell times, visit frequency, and zone transitions to deliver real-time physical space analytics comparable to Google Analytics for physical venues.
