Ed serves as Senior Analyst for Mobile Access Infrastructure in the Current Analysis Service Provider Infrastructure Group. He focuses on tracking, analyzing and reporting on developments impacting mobile infrastructure and mobile networking: 2G and 3G RAN and packet core along with, LTE, metro-scale Wi-Fi and WiMAX.
New base station introductions in the run-up to 5G pose challenges depending on both their timing relative to competitors’ moves and their messaging relative to legacy products.
All major RAN vendors have faced challenges unveiling new base stations recently, including Huawei, which was forced to make big changes in response to shifting market demands.
Everywhere you look, people are talking about the coming migration to 5G mobile networks. A much less talked about – but perhaps no less challenging – transition is the one radio access network (RAN) equipment vendors are making from base stations that were optimized for LTE to ones designed to lead operators into the 5G era. Yet, in the waiting period before 5G’s true arrival, marketing new base stations aimed at future networks alongside the current generation of base stations is a balancing act akin to stepping from an unmoored boat to a pier.

The lull between 4G and 5G operator spending motivates RAN vendors to penetrate enterprises before 5G, aided by new RAN technologies relevant to enterprises.
In penetrating enterprises, even RAN vendors with enterprise businesses face challenging organizational changes and market hurdles.
When RAN vendors talk about 5G, much of the discussion tends to involve targeting enterprise verticals and the Internet of Things (IoT). Take Ericsson, for example, demonstrating unmanned construction vehicles and remote surgery concepts. But, like many elements of their 5G discussions, RAN vendors aren’t waiting for 5G to target enterprises. Continue reading “RAN Vendors Targeting Enterprises Aren’t Waiting for 5G”→
AT&T wasn’t very candid in explaining how its latest lab project works, a twist on broadband over powerline.
Multiple forces might have given the operator reason to announce AirGig now, before it could say much.
AT&T’s announcement last week of a new technology dubbed AirGig was striking for a few reasons. One was the novelty of the technology itself, which enigmatically promised to transmit wireless signals around power lines rather than through them, putting a new spin on old broadband-over-powerline tech concepts and posing the possibility of self-backhauling mesh networks deployed along the power grid that could deliver 4G and 5G services to the home.
Another thing that was striking about AT&T’s announcement of AirGig was just how little about it the company was at liberty to discuss. For starters, how does the technology work, exactly? AT&T declined to elaborate much. How far could these networks (which use millimeter waves without necessarily being restricted to them and provide both access and backhaul) extend from a wireline backhaul source? It wouldn’t say. How would they be powered if, as AT&T offered, they wouldn’t need to physically connect to the power grid? Inductive (wireless) power transmission is one approach, the company said, but left it at that.
During my presentation, I listed some of the organizations that are helping to develop 5G technologies and standards. You know, industry groups (5GPPP, METIS, the 5G Forum, NGMN, IMT-2020, etc.), major universities (Harvard, Stanford, Cambridge, Shanghai Jiao Tong University, etc.), announced collaborations between specific equipment vendors and operators (Ericsson and LG U+, Huawei and Telefonica, Nokia and du, etc.).
I also made the point that achieving a certain level of unity on 5G is crucial for its stakeholders because no one wants to emulate the global division of 3G technologies that split the world into CDMA and WCDMA.
