伦敦学院发现Aruba网络Wi-Fi易于部署，安装插头
对于大学而言，如此许多其他组织，为用户自己的设备提供良好的Wi-Fi覆盖（Byod）现在是必须的。没有它，学生可以在其他地方的费用和学习中投票。但为现有建筑物添加Wi-Fi - 特别是学生居所 - 可能是一个艰巨的任务，需要建设许可，并对居民造成广泛的破坏。
Yet at historic University College London (UCL), the task of covering some 4000 student rooms in halls scattered across the city was achieved in just a few weeks and with minimal disturbance. That’s all thanks to the right choice of hardware: the AP93H access point from Aruba Networks – a compact multifunction device which combines dual-band Wi-Fi with Ethernet sockets and a small network switch, all in something the size of a smoke alarm.
Mike Turpin，UCL的网络服务负责人表示，该项目即将到来，但一旦它终于发生了，Aruba的支持和创新硬件使他的团队能够将三年的项目崩溃到一个夏天。“许多学生设备现在只有无线，如平板电脑和手机，以及他们与其他大学的大厅和服务进行比较，”他解释道。“所以我们已经意识到我们需要在一段时间内去无线，问题是资金不在 - 这是一笔公布的金额。”

然后通过幸福的巧合，三个重要的事情发生在一起相当靠近。首先是新普罗斯特或大学董事的到来，他们认识到大厅里的Wi-Fi的迫切需要，特别是因为UCL在国家学生调查中获得了IT服务的差，而且粪犬指出，“that’s a competitive point these days.”
The second was the opening of one new hall of residence and the refurbishment of another, both of which therefore needed modern Internet coverage in a hurry. And the third was meeting Aruba at a conference, shortly after learning about the AP93H, which enabled Turpin to start building a relationship with the company and get the project moving fast.
The challenge that Turpin’s team faced was that while the halls of residence had been flood-wired years ago with Ethernet, so students could plug in their PCs, the sockets were only in the rooms. After all, why would anyone need an Ethernet socket in the hallway? Yet the hallway was exactly where they would need a socket if they were to provide Wi-Fi the same way they provided it in the teaching and office areas, with traditional large access points (APs).
The AP93H was ideal because it avoided all the cabling and installation that the big AP route would have taken. “These are faceplate access points – they are a straight swap for the existing socket, plus as well as the Wi-Fi radios they have a four-port switch and a pass-through Ethernet socket,” Turpin explains. They are also Power-over-Ethernet devices, so with the right switches they do not need a separate power supply.
“最初我们只是在看选择，但我们意识到这一点faceplate APswere a way to avoid doing any building work, with all the paperwork that building work entails today. The physical size was the big win, but having the four-port switch as well meant all the bases were covered. We’ve seen no problems from the AP density – instead, having an AP in every room means guaranteed coverage including the hallways, plus if you lose one AP there’s adjacent coverage.”
他补充道，“我们与阿鲁巴建造了一个非常良好的关系，这一切都变得非常顺利。我们使用我们自己的布线承包商进行安装，因为他们已经知道该网站等。他们所要做的就是在RJ45上削减电线，压接，并插入。
“在表面上它不是最便宜的路线 - 你可能会覆盖相同的区域，远远较小的大接入点 - 但它削减了很多角落，并节省了很多偶然的工作，所以它的整体可能更便宜。此外，我们的居住大厅绝不是空 - 在大学假期期间有会议等等，但五到10分钟更换面板我们可以逃脱。“
UCL also needed to replace the existing network switches in its halls of residence – Turpin says some of these were over 10 years old, and of course they did not support Power-over-Ethernet. “We opted to use Aruba switches too, and then we have Aruba controllers in our data centre,” he says. This does mean having separate management interfaces for the residential Wi-Fi and the office Wi-Fi, but he says this isn’t a problem, given the high quality of the Aruba tools.
Turpin对AP93h有一个小小的遗憾，但他说他计划将其转变为他的优势。问题是，UCL具有稍微旧的接入点版本，每个版本只能在802.11A的时间一次使用一个Wi-Fi频带 - 与802.11a的802.11bg或5ghz - 不同于较新版本。他解释说：“这些APS是双频段，但你必须决定使用哪一个，所以我们在一个房间里与2.4GHz交错，下一个房间，5GHz等等。利用这将有趣的是对比较使用水平的2.4和5GHz进行一些分析。“
As well as restoring UCL’s competitive position on student IT services, flooding the residences with Wi-Fi will have other benefits. One is that technology-savvy students will no longer have a reason for installing their own ‘rogue’ access points, with all the security and management headaches that those can cause.
使用Aruba进行无线，也使UCL以非常有用的方式更新其一些其他系统。“有一个很好的阿鲁巴特征，让我们限制每房间的带宽，”帕林说。“大学的主要问题是版权侵权和文件共享 - 我们已经有一个粗略的方法来限制上传带宽，并且已经大量减少了问题，但现在我们还可以限制下载以提供更公平的可用带宽共享。
“In addition, we had a home-grown authentication system on the wired network but that was getting old. Now we use Eduroam as our main service, switching to a partnership with The Cloud during the summer vacation for conference guests. Aruba makes it easy for us to broadcast multiple SSIDs.” Eduroam is the world-wide wireless roaming service for academia.
The important question: would Turpin recommend the system to others? Absolutely, he says: “The University of London computer centre down the road is doing the same thing with Aruba – I told them it was by far the quickest and easiest way to get wireless out there.”
