6 Takeaways From Mobile World Congress Day 3

Analysts at Citi Research have been attending the Mobile World Congress in Spain this week. Here is a list of analysts' six takeaways from day three of the congress.

1. According to Ericsson ERIC CEO Jan Frykhammar, the company plans to keep opex flaT year-over-year (Y/Y) in 2015.

The company intends to ramp-down spending in the second half of the year to balance out large cloud and IP-related spending in the first half of the year.

2. Frykhammar projects little Y/Y change in business mix of coverage versus capacity in 2015, hinting that gross margins will likely also be flat Y/Y for Ericsson. He expects an eventual rise in margins from the new mix, but that rise may not come into play until 2016-2017.

3. Analysts believe that Ruckus Wireless Inc RKUS will win the Comcast Corp CMCSA wireless deployment as the MSO moves to .11ac.

Analyst do not believe this win is dependent on the timing of Comcast's deal with Time Warner Cable Inc TWC.

4. According to Ruckus CEO Salina Lo, Hewlett-Packard Co HPQ's proposed acquisition of Aruba Networks Inc ARUN would be a net positive for Ruckus in the long-term. HP's switching business competes with many Aruba partners, such as Juniper Networks Inc JNPR, Brocade Communications Systems BRCD and Dimension Data NTT.

Lo believes this conflict of interest could drive partners toward Ruckus.

5. F5 Networks Inc FFIV has seen a strong "create rate" lately for million dollar-plus deals.

6. F5 CEO John McAdam described the company's partnership with Cisco Systems Inc CSCO as "working really well."

F5 is seeing strong pull-through demand resulting from its partnerships with both Cisco and VMWare Inc VMW.
