After ten years of integration, how will Cisco respond to first-tier telecommunications equipment manufacturers?
The transition from mobile networks to all-IP networks provides fixed IP vendors like Cisco with business opportunities to target the growing area of ​​mobile networks. At the same time, Ericsson, Alcatel-Lucent, Huawei and Nokia Siemens and other leading telecommunications equipment manufacturers (TEM) are committed to developing internal IP technology and service platforms. Now, in order to compete for market share, direct competition between IP providers and telecommunications equipment manufacturers, which are also major providers of next-generation mobile IP infrastructure, will increase.
Service providers have always relied on telecom equipment manufacturers to design and integrate complete solutions so that they can gain an advantage in competing with certain small providers that provide specialized network elements. Cisco has played the role of a major supplier in the IP field of service providers. After internal product development and the acquisition of Starent, Cariden, Broadhop and Intucell, Cisco has become a major supplier in the mobile network field. Earlier, Cisco stated that Intucell can optimize heterogeneous network management (HetNets) by optimizing operators' existing macro wireless signals and dynamically integrating new small cells (third parties) into macro networks. Cisco's series of actions enable it to support multi-vendor mobile all-IP infrastructure.
Complete the last puzzle, the next challenge is to integrate
Over the past 10 years, Cisco has continued to build and acquire components of mobile network infrastructure. The Radio Access Network (RAN) is a missing segment of the Cisco solution. The transition to the next-generation mobile network architecture has opened a door for Cisco to fully penetrate the end-to-end (E2E) mobile infrastructure.
Cisco's announcement on April 3 that it acquired Ubiquisys means that the company's mobile network product portfolio is close to complete and has entered the mainstream of 4G RAN. Ubiquisys may be the last part of Cisco's mobile infrastructure layout and a key part of supporting the next generation mobile wireless access network architecture.
Whether all Cisco acquisitions can be effectively integrated to support its competition with Alcatel-Lucent, Ericsson, Huawei, and Nokia Siemens in the small cell or end-to-end field, and we need to wait and see. . Some experts believe that the primary purpose of the acquisition of Ubiquisys is to create a "neutral mobile host" to provide integrated broadband access for BYODs in corporate offices, hotels, and public spaces.
Telecom equipment manufacturers should view Cisco as a direct competitor, especially threatened enterprises and Internet services. As mobile infrastructure spending dominates the budget, Cisco ’s original core and edge router business is gradually being challenged by telecommunications equipment manufacturers, and to a certain extent, it has actively responded to the threats faced by its core router business.
