Mobile Broadband 

Three major trends are impacting communications networks of today.  Now that broadband is available to the majority of citizens developed nations, the next phase of unthethered access has arrived with the goal of providing truly ubiquitous access, with a major role for 4G wireless technologies.  This ubiquitous access will in turn drive the development of more powerful applications, resulting in a dramatic increase in data use.  Thirdly, wireless broadband will play a crucial role in less developed countries with little of no significantly developed communication infrastructure. By providing solutions that are affordable to deploy and inexpensive to maintain, millions of people will finally be able to enjoy voice communications and experience the benefits of internet access. 

Broadband Ubiquity

With the emergence of ever more powerful handheld devices, business and residential users of broadband services have come to expect the same performance of their portable devices. This requires an overhaul of the communication infrastructure that was build for narrow band voice services.  The arrival of fourth generation wireless all-IP technologies such as WiMAX, combined with robust fixed metro and access networks can deliver wireless broadband services equal to today's wired broadband technologies.

Data Use

Total Internet Data has been growing more than 40% per year in the last few years, but growth in mobile data use is expected to dwarf these rates....

Mobile Data Growth  Cisco expects mobile data traffic to grow with an annual CAGR of 92%, due to increased use, more powerful devices and fixed broadband substitution resulting in 2015 mobile data traffic over twenty six times 2010 traffic  (6250 petabytes per month).  While still only 8% of total IP traffic, mobile data traffic in 2015 will be three times the volume of the entire global internet in 2005.

These developments will have a major impact on the way communication networks will have to be designed.  

5G

The next generation of wireless transmission technology, commonly labeled 5G, promises to match and in many cases outperform the perfomance of fixed connecticons.
5G's improvements over 4G networks will come from a combination of technological innovations and the use of nearly 4GHz of newly auctioned millimeter wave spectrum
Today's 4G networks use less than 1Ghz of spectrum

Next to an increase in capacity of spectrum, 5G networks will also improve the spectral efficiency by reusing spectrum by using much smaller cell sizes.
The technological improvement will come from the miniturazation of basestations, all fiber connected to handle the increased backhaul requirements, and the use of powerful MIMO antennas. BWA Research has long advocated that wireless broadband access could provide an inexpensive and easy to deploy solution.  

BWA Research Group authored a white paper discussing the broadband technology options for rural communities.
