Will 4G make our networks irrelevant?

Already in many emerging markets, cellular phones are far more prevalent than computers, driving many in educational technology to consider non-traditional computing deployments that leverage cellular technology instead of optical, cable, DSL or other data circuits. Even in more mature markets, one has to wonder what role smartphones can play in keeping kids connected to data sources, documents, and communications media.

Now Verizon is testing its 4G networks which, according to PCWorld,

Once 4G speeds are generally available in major markets across the country it will transform expectations of what a mobile device is capable of and continue to blur the line between communications, entertainment, and productivity.

There are plenty of schools in mature markets (albeit in rural or inner-city areas) who are still struggling to put together a solid network infrastructure. Others are upgrading to deliver more bandwidth to more users. Still others are looking at the best ways to keep students connected through 1:1 initiatives. The PCWorld post goes on to describe the potential benefit of 4G:

The evolution to away from cellular technology to an all IP-based mobile connection also opens up whole new realms of functionality for roaming employees who need access to network resources. The improved security of IP networking combined with the increased bandwidth of LTE / 4G will allow users to work more efficiently and increase their productivity even if equipped with nothing more than their mobile phone.

If this sort of mobile bandwidth improvement can really be expected, then one has to wonder if the best connectivity for students might not be through 4G cards on laptops and netbooks or through increasingly capable smartphones. Why invest in infrastructure in and between our buildings when computers equipped with such equipment can roam as needed, between school and home, between buildings, on the bus, and anywhere else the providers manage to deploy 4G?

This vision is obviously a long ways off; 4G is only in early pilots. Clearly we also still need network infrastructure within our schools. 4G is not a panacea by any means. However, we may be approaching a time when we can rethink how we provide connectivity to our students, both on and off campus.
