各通訊電信業者的Wi-Fi漫遊服務:舊的方式和新的效果 Carrier Wi-Fi Roaming: Old Dog, New Tricks
出版日期: 2014年06月30日 內容資訊: 英文 12 Pages

漫遊與行動電話擁有同樣悠久的歷史,數次左右產業的興衰和變革。並且這次借助Wi-Fi的力量,再次引人注目。但,從10年前開始AT&T Wireless和Sprint互相的用戶已經可利用自家公司的熱點。Wi-Fi也以國際漫遊的方式而受關注。因為,LTE能使用的頻寬也剩得不多,實施國際漫遊不容易。由於近幾年EU的法規改革,容易不花成本提供漫遊服務,也對促進市場有所貢獻。由擁有多數的行動裝置使用者的企業用戶來看,使用Wi-Fi服務,可抑制通訊費並交換大量資料。還有Wi-Fi計劃,是使用者可比墊付通訊費日後和公司請款這樣的傳統方法更省錢的方法。

Roaming has been around almost as long as cellular, and more than once it has periodically disrupted the mobile industry, as well as rest of telecom. Case in point: AT&T's Digital One Rate, whose predictable pricing - a flat monthly fee instead of extra fees based on time, distance and place - was a milestone in convincing people to use their mobile phone as the primary or only phone. Landline hasn't been the same since.

Roaming is poised to shake up mobile and the rest of telecom again, this time with the aid of Wi-Fi. Wi-Fi roaming isn't new, nor is the role of mobile operators in facilitating it. For example, 10 years ago, AT&T Wireless and Sprint announced their first reciprocal Wi-Fi roaming agreement. AT&T customers could use their user IDs and passwords to log into five Sprint airport hotspots, while Sprint subscribers could do the same at two AT&T airport hotspots.

Wi-Fi is also evolving into a way to enable international roaming. One reason is because LTE's band fragmentation - 40-plus potential bands, roughly half of which are currently in use - makes international roaming a challenge for operators and customers alike. Another reason is because the EU's recently regulatory changes have reduced retail cellular roaming rates but not operators' cost of providing that service.

For MSOs, building a Wi-Fi network is cheaper than building a cellular network, if only because Wi-Fi doesn't require them to spend billions on spectrum licenses. But for MSOs and other owners of Wi-Fi networks, Wi-Fi also can be a money maker via inbound roaming revenue.these visions and eventually translate them into a practical, working system that can be produced and deployed profitably.

For enterprise customers, another reason for going with a paid Wi-Fi service is financial. Companies with a significant number of road warriors could contract with a Wi-Fi service to avoid big cellular data bills, especially when roaming abroad. Additional savings can come if the Wi-Fi plan has better rates than what employees could get on their own by paying with a credit card for an hour's or days' worth of service and then putting those charges on their expense report.

‘Carrier Wi-Fi Roaming: Old Dog, New Tricks’ identifies and analyzes key issues driving and inhibiting the market for carrier Wi-Fi roaming. The report is based on interviews with a representative sample of companies in the ecosystem.

Sample research data from the report is shown in the excerpts below:

Wi-Fi Offloading Increases as Cellular Gets Faster

                     Source: Cisco

For end users, Wi-Fi offload historically was attractive partly because it often was faster than 3G. So, in theory, Wi-Fi offload should seem like a step down compared to LTE, to the point that some users elect to stay on cellular. But in practice, that doesn't appear to be happening. One reason is because most operators don't offer LTE on a flat-rate, unlimited-use basis. And because LTE is so much faster than 3G, it's easier for customers to quickly burn through their bucket of megabytes or gigabytes. As a result, many mobile operators say LTE customers frequently take advantage of Wi-Fi when it's available so they'll have enough LTE data when Wi-Fi isn't available. The following excerpt shows how Wi-Fi offload will vary by cellular generation in 2018. For comparison, 54 percent of 4G traffic was offloaded in 2013.
