Now we have spent enough time in discussing how we got to 4G and the basics of wireless. It is time to know whats in store or what is the scope for improvement. As we all know there are going to be some huge technical challenges to cope up with the exploding number of connected devices. These challenges are going to be on both the fronts, network and device. From the network side people have come up with solutions like mobile data offloading to WiFi or Femtocell offloading..
It is interesting to read about challenges in LTE predicted a couple of years ago.
I am writing some of the challenges listed in 2009 in wirelessweek article.
1. Spectrum Harmonization
2. 2G/3G Spectrum Re-farming
3. Voice over LTE
4. Backhaul : Adding raw capacity, Realizing full mesh backhaul
5. Self Organizing Networks
6. Traffic Management
Surprisingly, many of these are still challenges and many more new challenges have been seen/tackled in these years as networks have been rolled out.
From the device manufacturers side, performance, cost and re-usability of devices remain the major challenges.
Now as we have discussed challenges speculated when LTE was in an infant stage and now when it is rolled out in a large part of the United States.
1. A looming spectrum shortage!! Every operator "just" gets 500MHz band.
2. Bandwidth issues
3. Unlimited data plans : lead to enormous data usage.
4. 2G and 3G networks are still there..It is not entirely LTE.
Here now on, I am trying to take one problem a month and read/write as much as I can,
