is 300 mm^2 which is about 17.33 sq mm

Is the compression non-lossy?

Actually the problem with 3G is not the size of the module at all, but the fact that 3G drains the battery very fast, and the costs from the providers are vastly higher compared to other technologies.

3G doesn't drain the battery any faster than any other technology. If you're comparing with 2G, then yes a 3G module working at full data rate will drain a battery quicker than GPRS at full data rate, but if you have a constant amount of data available, the 3G will finish sending it much quicker, so its overall consumption will be lower. And idle consumption is lower for 3G than 2G. LTE may be better still, but outside major city centres and away from highways there are few places where you will find coverage.

As for cost from providers, that may be a problem you have with your provider, but it is not universal. In most parts of the world, data is charged the same, no matter what technology it is going over.

And pregnancy — and subsequent child-rearing — do cost women professionally. Not because anybody is "sexist", but simply because you can not give a promising assignment to an employee, who just is not there (because she is on maternity leave).

The problem is this all too often extends into not giving women promising assignments because she just got married and might start making babies soon, or because she is about the age that society expects her to want to do that. That is why even in superficially equal societies such as we have in the West, women are still far from equal.
