The 4G road ahead: Some common denominators for WiMAX and LTE

For a long time, it has been held that WiMAX has a definite and powerful time-to-market advantage over LTE and LTE-Advanced networks. This is because of WiMAX’s maturity as a technology, but also due to its higher readiness to be deployed. On the other hand and despite the many commitments, LTE remains at the trial stage largely.Recent market reports, however, indicate thatWiMAX’s advantage may be short-lived and that WiMAX, despite prospects of growth, will be eventually eclipsed by LTE’s growth, which is projected to take an exponential at the time of writing this article.More generally speaking, both...

A Future Internet Concept: In-Network Clouds

One of the key aspect fundamentally missing from the current Internet infrastructure is an advanced service networking platform and facilities, which take advantage of flexible sharing of available connectivity, computation, and storage resources.

The current Internet has been founded on a basicarchitectural premise, that is: a simple network service can be used as a universal means to interconnect both dumb and intelligent end systems. The simplicity of the current Internet has pushed complexity into the endpoints,and has...

Traffic Evolution Characteristics of the Mobile Internet

Mobile Internet has recently started to become a reality for both users and operators thanks to the success of novel, extremely practical smartphones, portable computers with easy-to-use 3G USB modems and attractive business models. Based on the current trends in telecommunications, vendors prognosticate that mobile networks will suffer an immense traffic explosion in the packet switched domain up to year 2020.

One of the most important reasons of the traffic volume increase in mobile telecommunications is demographical....

LTE: Backhaul Considerations

Owing to the high peak and average speedsof LTE, high-speed backhaul links are essential to ensure that the capabilitiesof the LTE air interface can be fully utilized. A three sector eNode-B with a channelbandwidth of 20MHz in each sector can easily achieve peak datarates that arethree times 100 Mbit/s, that is, 300 Mbit/s in total.

As eNode-Bs are usuallycolocated with UMTS and GSM base stations, the required combined backhaulbandwidth could hence be even...

Challenges and Opportunities for 4G Wireless Video

As depicted in the illustration below, the world has become a content producer. People create and upload their own pieces of art onto the network while enjoying other people’s masterpieces. It may be expected that in 4G the communication networks will continue to expand so as to include all kinds of channels with various through puts, quality of services and protocols, and heterogeneous terminals with a wide range of capabilities, accessibilities and user preference.  Thus the gap between the richness of multimedia...

Mobile Broadband Connected Future: From Billions of People to Billions of Things

The purpose of this report is to discuss the opportunity for wirelessly connected devices. We explore two main themes: Why embed devices for mobile connectivity? And why choose to embed the 3rd Generation Partnership Project (3GPP) family of wireless technologies?

The findings of this report impact mobile operators, mobile infrastructure providers, chipset manufacturers, device original equipment manufacturers (OEMs), solution providers, vertical enterprise industries, horizontal consumer and enterprise...

The Onion That Makes Telcos Cry

Mainly due to the success of the Internet with its steady growth and ubiquitous reach, IP has for a long time shown its predominance as the preferred protocol and has more lately become the one protocol on which to base each application. However, network operators have been for many years compelled to deploy several other technologies to implement the services they wanted to sell. This led to the “networking onion” shown in the illustration here where various technologies are deployed in layers to...

How Seamless Mobility will shape the the Digial Swarm: Blurring Boundaries

As devices get smarter and users can access resources and applications from anywhere, the domains of work, home, and personal life will eventually become blurred. Will it really matter when, where, and how you watch your ethics training video, as long as you do it? Will anyone be willing to carry more than one device hat supports the full spectrum of enterprise and entertainment applications?

We are already seeing strong signals today as users are insisting on bringing their consumer-based applications and...
