Re: Deployment delays?
Yeah, I definitely see people being a little more confident in steering towards 2015 for larger deployments now. We've been burnt before though.

Re: Deployment delays?
Unfortunately due to the complexity of the environment they need to enter there are more barriers surfacing that need to be surmounted, which has caused significant delay for the early optimists. But IMHO I would say that more than 95% of teh issues have been resolved or are in the process of being resolved, while the remaining issues have a clear roadmap toward being addressed.

Re: Secure Small Cells
Not saying that PTP won't be used. Just haven't got the impression from the industry that it is so purely cut and dried is all...

Re: Deployment delays?
Let's hope, eh? Seems like some vendors are banking on that.

Re: Secure Small Cells
Small cells will mostly be connected via microwave or millimeter wave, and their topology may often prevent line-of-sight. These circumstances, coupled with the aforementioned security risks, will prevent operators from relying solely on GPS in small cell networks. Among PTP's many features are several mechanisms that can correct for the large packet delay variations (PDV) often found in IP switches and routers. Because even foul weather can increase latency over wireless connections, PTP's defined hierarchy of clocks will be the primary means of delivering nanosecond-accurate frequency and time-of-day synchronization in small cell networks.

Re: Deployment delays?
I agree. Small cells have generally been plagued by numerous issues that need to be resolved before they take pride of place in the network, which is what's been holding themup for awhile. But the indusry has been very good at methodically going about and addressing the various issues, such as interference, timing, backhau, physical securityl and regulatory, so there's no reason why security will be any different. 

With every additional hurdle being addressed small cells gain more credibility as an option for more deployment scenarios.

Re: Secure Small Cells
Ha,

Come now, everyone in the industry is dead set on using PTP for sync? Really?

Re: Secure Small Cells
Good point, Dan. Whether intentionally spoofed by a hacker or unintentionally thrown off by a passing jammer, GPS can easily fail small cell backhaul networks. This is undoubtedly one of the biggest differences between macro and small cell networks. GPS will likely remain the primary timing solution for macro networks, because it can deliver the combination of phase/time-of-day and frequency synchronization required by LTE networks. However, the numerous security risks mentioned above will force operators to rely on the IEEE1588-2008 Precision Time Protocol (PTP) for accurate network timing in small cell networks. Obviously, getting PTP-enabled equipment to play nice with network encryption will be the next challenge. Operators will need to demand the latest small cell backhaul technology to ensure their grand 2014 plans come to fruition.

Security is built-in, not bolt-on
Sarah,

Read the article with great interest. The Small Cell system the we, at SpiderCloud, have created is purpose built to incorporate numerous security related features down at hardware level (in addition to robust software practices on top of that). These features are both for hardening and meeting security performance goals. Systems architects have to assume an end-to-end hostile environment due to equipment being installed outside the physical control of the mobile operator's. The operator's we are working with are deeply concerned about security and it's not a secondary concern to be dealt with later. The old adage: "You don't really want an incident to put your company on the front page of the Wall Street Journal" is still valid

Vitesse is right that IPSec should not be done in the core processor. In our case, offloading IPSec to a hardware accelerator is acutely important as we can have 100 Radio Nodes running IPSec to the Services Node and one really big IPSec tunnel originating from the Services Node to the mobile operator's Security Gateway in the core.

Re: Secure Small Cells
Don't forget the ol' GPS jammer trick to screw with the backhaul sync!
