Since the release of Apple watch in April 2015, a considerable amount of articles have been published on the features of the watch and how it connects to the iPhone through either Bluetooth or Wi-Fi. Unlike those pieces, this article analyzes the impact of the Apple watch on the wireless network.
The Apple watch is powered with watchOS and features Bluetooth 4.0 Low Energy and 802.11b/g/n to connect to the iPhone 5 or later version. The Apple watch is single band and thus works only in 2.4 GHz. Although there are two modes of communication, the Apple watch’s primary mode of connectivity is Bluetooth to transfer data back and forth between watch and iPhone. If the Bluetooth is off, the watch switches to Wi-Fi to stay connected to iPhone. However, this switching process is not seamless for all wireless networks. Sometimes the watch loses connectivity to iPhone altogether if the Bluetooth is out of range or if it is disabled on the phone. Since the watch is single band, it cannot connect to 5GHz band. However there is a work around to allow it to talk to iPhone that is associated to an AP using 5GHz radio.
Steps to make Apple watch talk to iPhone on 5GHz
- Forget the 2.4 GHz and 5GHz SSID on your phone. Enable the Bluetooth on the iPhone and make sure the watch is connected.
- Connect to 2.4GHz SSID on iPhone and then disable the Bluetooth.
- The Apple watch should now show connected to iPhone via Wi-Fi after a brief disconnect. Test it by pinging the iPhone from the watch by pressing the phone icon shown below in the picture.

Many network engineers recall the iOS7 update on September 18, 2013 as one of the most historic download days of their network’s history. All the more reason for us in the wireless world who anxiously anticipated the September 17 release of iOS8.
We asked a few of our customers to monitor the effect of the software release on their networks and the results for the first two days are in. Those in the education and healthcare space in particular are filled with early adopters of WiFi technology and devices, and eager to get their hands on the latest updates.
Joe Rogers, Associate Network Director at the University of South Florida shared this picture with us from 1pm September 17th, showing 1 Gbps more traffic than he would normally see at this time of day:
Another customer, Greg Sawyer, Manager of Infrastructure Services, shared this picture of the iOS8 effect on his network at the UNSW Australia.
He noted that his experience handling the release this year felt smoother than last year, despite the new peak internet download of 4.65 Gbps and 21Tb downloaded for the day! Not too surprising when considering that there were 27,000 concurrent connections on the wireless network and approximately 60% of those being Apple devices.
How should organizations be considering and handling these network spikes? I sat down with Cisco technical leaders Matt MacPherson and Chris Spain (@Spain_Chris) to get some insight on the effect of big updates like iOS8 on the wireless network. Here are some of the highlights of what we discussed:
The World We Live In

The holiday season which began with Cyber Monday on December 2nd 2013 has just ended and analyzing the impact on mobile commerce sales and location based services unveils some very interesting trends.
Firstly, at the macro level:
- Online shopping increased in the USA in 2013 by over 16% compared to 2012.
- From a mobility perspective, almost a third of all online sales (29%) were made from Smartphones or Tablets.
Clearly there are changes in the online marketplace, but in order to examine this a little further, let’s look at a few key questions to help understand what is happening in this marketplace:
- What are the major trends?
- Is mobile commerce just a US phenomenon?
- What impact does location based services have?
- Where are the main benefits coming from analytics?
- How is privacy fitting in to all this and how is the attitude of mobile consumers evolving?

With the introduction of Cisco mDNS Service Discovery Gateway in IOS, customers that have implemented the solution are observing client behavior they haven’t seen prior to extending services across subnet boundaries. One of the effects is the duplicate name issue seen when devices with enabled services are moved from one L3 subnet to another L3 subnet and these two subnets happen to be connected to the same router/switch running the Service Discovery Gateway (SDG).
When devices (like a Mac OS X computer) offer a service such as Remote Login (SSH) or Screen Sharing (VNC), they will announce these services using mDNS/Bonjour/Zeroconf using their hostname as configured in ‘System Preferences -> Sharing -> Computer Name’ (see Fig. 1).
