Mobile UC at Catalyst Conference

Individuals increasingly work from nontraditional office environments and expect to use their mobile phones wherever they work. At the same time that the mobile workforce is growing, enterprises are deploying Internet Protocol (IP) Telephony (IPT) and unified communications (UC) solutions. IPT systems provide new capabilities to virtualize communications across the enterprise, breaking the linkage between [...]

The Mobility Moment show is now live

We live in an increasingly mobile world. More than half the people on earth have a mobile phone so it should come as no surprise that there are more calls made using a mobile phone than a traditional telephone. In fact, many mobile professionals are blending their personal and professional lives by using sophisticated smartphones [...]

Comparison of beamforming technologies

This is the fifth post in a series that delves into the subject of beamforming. In this post, we compare all three beamforming methods (static, transmit, dynamic).

Although all three beamforming technologies provide SNR gain, they are quite different. In addition, all types of beamforming can exacerbate the following problems:

Sticky client problem: The sticky client [...]

Dynamic beamforming

Dynamic beamforming focuses RF energy in a particular direction and with a particular shape in order to increase the Signal to Noise Ratio (SNR). In a sense, it is like static beamforming in that it focuses RF energy, but it is different because the antenna array’s radiation pattern can change from frame to frame (see [...]

Transmit beamforming

In this post, we continue my discussion of beamforming by focusing on transmit beamforming. As previously mentioned, beamforming is a method of concentrating radio frequency (RF) energy in order to improve the signal to noise ratio (SNR) at the receiver, thereby improving network performance and predictability.

Transmit beamforming (TxBF) is a method of transmitting two or [...]

Static beamforming

This post continues my discussion on beamforming which is a method of concentrating radio frequency (RF) energy in order to improve the signal to noise ratio (SNR) at the receiver, thereby improving network performance and predictability. In this post, we discuss static beamforming.

Static beamforming provides a fixed radiation pattern by using a directional antenna. Virtually [...]

Introduction to beamforming

Beamforming is a method of concentrating radio frequency (RF) energy in order to improve the signal to noise ratio (SNR) at the receiver, thereby improving network performance and predictability. Enterprise WLAN vendors are now integrating beamforming technology into their access points (APs) so it is important to understand the types of beamforming and the benefits [...]

What to ask before you buy a femtocell

Introduction

Femtocells are all the rage. These tiny cellular radios promise to improve in-building cellular coverage and are primarily targeted at the home user. However, some vendors are now building enterprise femtocells. Should you consider femtocell deployment in order to improve your cellular coverage? This article identifies the key questions you should ask before you buy [...]

MobileParadigm.com is 1 year old today

Thanks to all of you that have been reading and commenting on my blog. I will continue to focus on providing in-depth enterprise wireless and mobility analysis. Year 2 will feature more frequent postings and I may experiment with video blogging.

As Steve Jobs said in his 2005 Stanford University commencement speech: Stay Hungry, Stay Foolish [...]

Does the iPhone set the pace?

Many users have decided that Apple’s iPhone is the right device for them – but is it the right device for mobile IT? Tomorrow at the Mobile Business Expo I will chair a panel that explores the opportunities – and issues – inherent in the iPhone and its competitors, and help attendees prepare a checklist [...]
