Top 5 Reasons to Choose a Cisco Wireless Network for the Apple iPhone 5 & Other Dual Band Smartphones

September 21, 2012 - 0 Comments

Last week Apple dominated tech headlines when it announced details of the iPhone 5. With its release today, thousands of fans will line up across the globe to be the first to try the new smartphone.

There have been a number of iPhone improvements, but the one I find significant is the fact that the iPhone 5 will have dual band Wi-Fi. This means that in addition to supporting the 2.4GHz band, it will now support the 5GHz band. Why is this significant? Well, the iPhone joins a number of other smartphone vendors who now have products capable of operating in both the 802.11b/g/n (2.4GHz) and 802,11a/n (5GHz) Wi-Fi bands. Other vendors that stack up include Samsung’s Galaxy S III and HTC’s One X.

Why is this 5GHz important? There is certainly nothing wrong with the 2.4GHz band. Both bands are unlicensed in most regions of the world. However, with the proliferation of devices due to the growing BYOD trend, the 2.4GHz band is getting real crowded. Remember: the 2.4GHz band only has 3 non-overlapping channels available. Think about it: all these devices like smartphones, laptops, tablets, and access points are competing for the available bandwidth while interference increases.  In short, the 2.4GHz band just doesn’t have enough capacity for all these competing devices.

We’ve all read the recent articles written about the iPhone 5’s improvements and new features; let’s have a conversation around how the iPhone 5 will affect business users, and how the right network can improve the performance of the device.

With a predicted 27 million iPhone 5’s expected to sell in September, we can expect the BYOD trend to continue. We know that come Monday September 24, there are going to be a lot of iPhone 5’s walking through your office door.

With this in mind, I wanted to share how a Cisco wireless network will help your business get the most out of your new smartphones. Cisco technical marketing manager, Jameson Blandford, shares his top 5 reasons why an optimized Cisco network will allow your smartphone to work to its full potential.

Jameson’s Top 5 Reasons to Choose a Cisco Wireless Network for the Apple iPhone 5 & and other dual-band smartphones:

1. BandSelect for Clean 5GHz Operation

The BandSelect feature keeps previous generation iPhones on the legacy 2.4GHz spectrum while enabling the new dual-band iPhone5 to utilize the cleaner and less crowded 5GHz spectrum, which has less interference, more available channels and higher speeds.

2. ClientLink Beamforming and Cisco CleanAir for High Data Rates

The ClientLink 2.0 feature on the Aironet Series Access Points utilizes per-subcarrier ODFM beam forming for any 802.11n client, which means that the iPhone5’s 40MHz capable chipset can remain closer to its maximum data rate of 150Mbps. ClientLink 2.0 can also help when there is a mixed client network where legacy 802.11a/g devices can also benefit from a more efficient data rate. In addition to ClientLink 2.0, Cisco’s CleanAir feature automatically detects and avoids devices like cordless phones, microwave ovens and video cameras that can cause interference and reduce data rates.
3. Airtime Efficiency for Multiple Clients

Cisco’s custom packet scheduler allows the Access Point to serve multiple clients fairly using a round-robin algorithm. In order to ensure that airtime is used most efficiently, the system will maximize the number of packets that can be aggregated to each client.

4. 5GHz Dynamic Frequency Support for Capacity

Cisco allows the use of all possible 5GHz channels as permitted by the regulatory domain by supporting nine 40MHz-wide channels in the 5GHz spectrum. Without DFS (dynamic frequency selection), alternative WLAN infrastructures only support four 40MHz-wide channels

5. Bonjour Services Directory with Device Discovery*

Specifically for the Apple devices in your network, the Cisco Bonjour Services Directory functionality enables cross-subnet service discovery for devices like an Apple TV or AirPrint-capable printer. The feature also includes packet optimization capabilities that reduce Bonjour network traffic.


So if you are one of the many that will be lining up for the iPhone 5, consider how your network can affect the performance of your newest device. Given the sea of devices thanks to BYOD, it is increasingly important to remember that devices will only reap increased productivity if they are properly connected. Only the right network can optimize those benefits.
