Huawei's "Two Cloud" solution for Mobile Broadband

In case you are a regular and noticed my recycled image for this post then let me tell you that the post is about recycled ideas ;)

It is a well known fact that I have mentioned at various places in the blog as well that the higher the frequencies, the smaller the cell radius. Since we know that the common deployment frequencies for LTE would be around 2.6GHz then the signal penetration through walls may not be great.

As a result we will be forced to use Hierarchical cells that would allow load balancing and also higher speeds as the smaller cell sizes translate to fewer users and interference.

The following is from Huawei's website:

Based on our roadmap of early success in mobile and fixed broadband network construction, Huawei now responds to the mobile broadband dilemma facing global operators with the unique "Two Clouds" solution.

Employing optimal topologies for access networks providing DSL-level bandwidth for users across the board, the two clouds work together to deliver the most cost-effective means of enhancing user experiences.

  • A high speed cloud, consisting of Pico and AP BTSs, is typically deployed in densely-populated urban areas to deliver an average bandwidth of 2 Mb/s.
  • A continuous cloud of macro BTSs is applied for wide coverage delivering a bandwidth of 256 to 512 kb/s.

Huawei's "Two Clouds" model allows operators to profitably deploy mobile broadband networks while utilizing an intelligent site management framework to automatically adjust bandwidth and reducing construction, operation, and maintenance costs.

Incorporating this framework, flexible network mapping permits manageable, controllable mobile broadband networks, ensuring continuous network coverage in various scenarios, and provides users with inexpensive, quality broadband services. Very convincingly, Huawei's "Two Clouds" concept can reduce the cost per bit by as much as 70%.

One can guess that Self Organizing Networks would play important part in realising this in practice.

Ajit, not sure if this would go well with the Forox topics. Will try.
