As the carriers grow their 4G networks, however, I believe enterprise adopters won’t be able to count on the availability of 4G speeds in all the places that matter to them, as long as 4G coverage remains in isolated islands rather than concentrated regions.

For 2011, 4G will be an option that people want but won't rush out to their store to get, and users will certainly show up with a handful of devices that support various 4G types, but 4G won’t be an operational must have through the year. So for enterprises and 4G, 2011 will be a testing and check out year.

WiFi, on the other hand, will only continue to grow in importance for almost every enterprise. 802.11n-ready equipment has been available for several years, ratified as a standard for more than a year, and enterprise products are entering their fourth generation of development already.

Speeds are super fast and WiFi companies are delivering better equipment with smarter management, adaptability and reliability in the face of interference, noise and large client pools.

This year I’ll be interested in whether *WiFi Direct (see paragraph immediately below) will bring any operational benefits for enterprise networks and users. It is believed by many to be a big issue this year.
+++++++++++++
*What is WiFi Direct?  Wi-Fi Direct is a new capability of Wi-Fi wireless networking  for consumer products. Wi-Fi Direct is a greatly improved form of  ad hoc mode WiFi that allows devices to also connect to each other directly rather than solely through access points.

The creators of Wi-Fi Direct are quick to point out that it does not replace a broadband router. Instead, the technology is designed primarily to simplify the sharing of resources (including printers) between mobile devices. However, with an enabled Internet modem and home computers, a Wi-Fi Direct home network could also share an Internet connection easily enough without the help of a router.

I also think arguments around enterprise WiFi architecture will continue to get bigger and bigger. Motorola’s announcement of its WiNG5 architecture–moving more network intelligence toward the edge–is a dramatic technological shift from a company that was previously heavily invested in keeping the network intelligence in the core.

I suspect more WiFi companies will see the light, and that Motorola was correct by putting network intelligence back at the AP (access point), and that removing the central controller altogether from the data path removes the biggest performance bottleneck and frees the APs to serve more clients and more traffic effectively. And better performance at the edge will be paramount as users continue to flood enterprise networks with WiFi-enabled iPads, Android phones and BlackBerrys.

Blackberry, RIM’s forthcoming PlayBook tablet is a large company bet too.......for RIM, which is taking a great leap to retain relevance and mindshare for mobile consumers and enterprise adopters alike, as the Playbook is both a new hardware form factor and a new mobile OS (the latter based on RIM’s QNX acquisition).

I’d say the PlayBook will be a moderate success at best, as the requirement to tie to a BlackBerry smartphone for e-mail and enterprise connectivity is shortsighted and limiting.

But I suspect the OS and software will be a major winner, which is ultimately more important to the future of the company. I’ve liked what I’ve seen from RIM in terms of developer outreach over the last year, and I suspect QNX will pay off big to attract more of that core audience. And better apps will equal more consumer appeal for later BlackBerry devices running QNX, whatever the form factor.
