Edging Closer Towards Disruption in Radio Access Networks

Cloud-RANIn past articles [1, 2], I stressed that Cloud RAN is a disruptive technology. There are a few reasons for this, but I think that most critical reason is that Cloud RAN breaks open a pricing structure that’s been in use ever since the wireless industry was created. The current pricing model for base stations is based on a tight coupling between hardware and software that is impossible to separate. So, when a network operator buys a base station, the operator selects how many frequency carriers each sector would support and a corresponding number of remote radio heads. This model becomes obsolete in Cloud RAN where the hardware and software are decoupled. There is no longer a 1:1 relationship between baseband modules and RRHs due to pooling and virtualization. New pricing schemes are now possible as there is more room for operators to optimize the subsystems they need in the network. Cloud RAN not only decouples hardware from software, but also changes the coupling among hardware subsystems. This has profound implications on the future cost structure of wireless networks and operators have taken notice. OEMs looking to challenge the position of the primary entrenched incumbents are leading the charge in Cloud RAN development with a vision to increase their market share. Read more of this post

Is LTE-U DOA?

LTE-U vs Wi-FiReading some of the literature about LTE-U (and LAA) leads you to believe that its deployment is a foregone conclusion: operators love it; vendors support it, and products will be available within months. But operators lack the sales channel into the enterprise where LTE-U is envisioned to be deployed and provide most value.

While LTE-U may find its way into the handset fairly rapidly, its path into the Wi-Fi access nodes will be long and arduous as that ecosystem is not particularly friendly to LTE-U (Cisco for example), while the channels of the small cell vendors, such as Huawei and Ericsson, into the enterprise are less established.  Read more of this post

Is LPWA for Mobile Network Operators?

Is LPWA for MNOsYou don’t need to be a wireless carrier to operate an LPWA network and provide IoT connectivity services to hundreds of thousands of devices. LPWA technologies operate in unlicensed spectrum which opens a wide door to anyone to play in the IoT connectivity space, including of course mobile network operators (MNOs). But is LPWA for MNOs? Or more precisely, LPWA opens the door for new applications and business models, but to what extent can MNOs leverage LPWA and can they make a successful business out of it? Or are LPWA networks best run by new entities unencumbered with legacy solutions and processes? Read more of this post
