Over the course of this series, we’ve discussed how enterprises can better enable people to work in their own way, regardless of where they are and what device they are using. We started by making smart plans at an architecture level and then implementing secure policies along the way. The final step enterprises need to take may be the hardest one of all but can yield the greatest results. To increase productivity, business agility, and customer satisfaction, enterprises must actively embrace mobility in the workplace. Here’s a short checklist to help organizations with this last step:

1. Go Beyond Provisioning Mobility for Sales: Think “All-Company” Mobility.

The definition of mobility is expanding to include not just “road warriors” but also “corridor warriors,” as well as guest and home workers.

Make sure your mobility architecture is designed to accommodate them all. Then create a phased implementation plan. Determine which users and business processes you want to prioritize first and move forward at a pace that makes sense for your enterprise.

An all-hands-on-deck approach will also help drive future implementation of mobile solutions. Read More »

Get Your Network Ready For iOS7

In their highly anticipated announcement this week, Apple introduced two new phones, the iPhone 5C and iPhone 5S, and confirmed that iOS 7 would be released on September 18th. Techies like myself took note that iOS 7 will include quite a number of new features. We at Cisco want to help you understand what iOS 7 means for your network, so here’s a quick blog to sum it up:

How does iOS 7 impact your wireless networks?

Soon your employees and guests will be upgrading to IOS 7. Did you know up to 20% of traffic to mobile devices is software upgrades, application updates and synchronizing your devices via the cloud? Cisco’s Application Visibility and Control technology can help you identify and tame these applications and is available on the routers, Wireless LAN and visible via Prime Infrastructure. In addition, Cisco’s ISR can cache these updates to reserve valuable and expensive WAN bandwidth. More details about protecting the WAN is available in another blog.

If you leverage a Captive Portal, you will experience a change in behavior. Apple has enhanced the Captive Network Assistant (CNA) functionality iOS 7 making it more robust. Cisco has proactively developed and tested a new version of wireless LAN controller code to interoperate with Apple’s new implementation while ensuring a seamless experience for all other clients.

Finally iOS 7 also has significant security and manageability enhancements to improve productivity for the enterprise.

What do you need to do in order to optimize for iOS 7? Read More »

IoE: Dead or Alive on Wireless

When we examine the average wireless client on a network today, we see a few options. There is the smartphone, the tablet, or the laptop. Even the Apple TV and Roku are often based off of similar technology and chipsets. All of these devices connect to a wide range of services, often consuming large amounts of bandwidth: we stream music while we browse; we video chat with friends, family, and coworkers across the globe; catch up on our favorite shows or sports teams. Occasionally, we do all of these things at the same time.

Our current wireless networks are built to handle this type of traffic. With 802.11AC, it is clear that we will be ready for anything that our standard client will encounter in the near future.  But what happens when the standard client model is broken?  The increasing shift to an Internet of Everything (IoE) forces us to face this question about the future of wireless clients.

There are lots IoE devices already on the market, and the next couple of years will see developments not that dissimilar from those during the “internet revolution” of the late 90’s. Finally, the average user will have the access and the ability to afford the smart homes we have been dreaming of for the past thirty-plus years. Read More »

The Fifth Step to Enterprise Mobility: Defending Your Data

This is the fifth post in a blog series featuring Vine-format videos focusing on the “Six Essential Steps for Unleashing the Power of Enterprise Mobility”. The first blog post discussing how to build a mobile structure can be found here. The second blog post highlighting the benefits going virtual can be found here. The third blog post focused on preparing enterprises for the division of devices can be found here. The fourth blog post focused on creating an app checkpoint can be found here

In a 2012 survey of IT executives and CEOs, nearly half of the companies that permit mobility and BYOD reported experiencing a data or security breach as a result of an employee-owned device accessing the corporate network. In addition, security concerns continue to remain a key issue for decision makers looking to deploy additional mobile solutions such as enterprise mobile apps, according to a recent article from IT Pro.

Careful planning can help enterprises manage security concerns and harness the power of mobility. Here’s a brief checklist to help organizations secure devices, data and the network:

1. IT Pushing of Capability Down to End Devices

 IT needs to be able to push capabilities down to end devices and access control for both on-premises and off-premises apps, while providing pull capabilities for users, so they can self-provision apps.

IT must have the ability to apply situational control policies (for example, for disabling cameras on mobile devices in order to protect on-premises company assets when employees and guests are on corporate premises or in restricted areas). Another must have? The ability to remotely locate, lock, and wipe devices should there be a theft or if an employee leaves the company. It is also essential to be able to automate geo-specific policies to control roaming costs when workers are out of country. Read More »

Interference Detection and Mitigation with Cisco CleanAir

The previous blog on CleanAir went in depth on how MSE uses CleanAir information to locate interferers and the impact zone for each interferer. This blog takes a step back and gives an overview of the CleanAir technology.

How Interference Affects Your WiFi

802.11 devices operate in the 2.4GHz and 5GHz unlicensed bands. These are unregulated and experimental bands. As such, there are way more non-802.11 devices, including but not limited to cordless phones, video cameras, microwave ovens, Bluetooth headsets, DECT phones and even X-Boxes. Now even more devices are coming out that emit in these bands. These devices interfere with your WiFi network since they don’t work cooperatively with 802.11 devices, causing reduced network capacity and coverage, poor quality of voice and video, and link failures.

When an 802.11 device is ready to transmit and it senses interference, it will hold off transmission until it is finished.  If it is in the middle of a transmission where it has sent a packet and never receives an acknowledgement, then it will try to send the packet again. Issues like these  impact the throughput and capacity of your Wireless Network. An interferer like a microwave oven, which emits interference on a 50% Duty Cycle, will reduce the throughput by 50 percent. In the case of an interferer like a video camera, which emits interference at 100% Duty Cycle, when seen at Access Point above CCA threshold will stop the Access Point from beaconing. Due to this clients will not attempt to associate. Read More »
