Limited network bandwidth and fixed browsers means we have to optimize the efficiency of how the browser and phone connect to the data center. If we cannot change any aspect of the browser, and we cannot expand the bandwidth, we probably should focus on handling the load better.

You can do any of the following:
1. Improve the algorithm handling bandwidth distribution from wireless cells to support a more dynamic structure permitting users to aquire more of the available bandwidth inversely proportional to the demand.

2. Improve the data center's ability to process incoming requests, possibly increasing its caching size, the number of parallel processors running, improving the connection hardware to raise transfer speed, or even refine the relay setup to optimize the transfers between the deployed wireless cells and the center.

3. On the phone, you can obviously upgrade all the hardware, affording more memory to browser, additionally a upgrade to the wireless component to allow for multithreading of connections or maybe synchronizing with local cells to improve quality.

4. Alter the phones thread scheduler to always prioritize the browser and the connection requests above anything else. (not the smartest move but it would certainly mean less delays on usage of the browser)

5. Prevent the installation of addons and plugins for the browser in the phones os or optimize for the specific browsers

6. add a ethernet port to the phone because no one said the connection has to be wireless all the time.

7. Have several thousand support techs or use a automation program to manage the networks allocation of bandwidth and priority.

This is, of course, all speculation. Rather nebulous question.

Hasnt Amazon did this with the browser inside their fireOS? They optimize all the webpage by handling/caching the webside in their datacenter and sending the website formated/optmized for their phones/tablets?
