FOR IMMEDIATE RELEASE



        CERAGON NETWORKS BREAKS WIRELESS CAPACITY BARRIER WITH INDUSTRY'S
                      FIRST 311 MBPS COMMERCIAL DEPLOYMENT

        FIRSTMARK COMUNICACIONES ESPANA INSTALLS NEW FIBEAIR(TM) 3100 IN
                             NATIONWIDE SDH NETWORK


   TEL AVIV, ISRAEL, MARCH 15, 2000 -- Ceragon Networks Ltd. (NASDAQ: CRNT), a
global provider of high-capacity broadband wireless systems for next generation
communications networks, and First Mark Comunicaciones Espana, a leading
broadband operator, announce today that the broadband wireless capacity barrier
has been broken with the industry's first commercial deployment of a 311 Mbps
system, Ceragon's FibeAir 3100.

   The FibeAir 3100 is a scalable, ultra-high capacity wireless networking
solution that enables service providers to progressively increase network
capacity from 155 to 311 Mbps. Based on Ceragon's FibeAir 1500, the FibeAir 3100
operates in the same frequency channel in dual polarization, thus doubling the
capacity over a single channel. The FibeAir 3100 is compliant with ETSI and FCC
standards for operation worldwide.

   FirstMark Communications is building out a pervasive, end-to-end broadband
communications network in Europe. FirstMark Comunicaciones Espana is deploying
both the FibeAir 1500 and 3100 systems, operating in the 38 GHz band, to provide
high-speed connectivity throughout FirstMark's wireless metropolitan network in
Spain.

   "Ceragon was the first company in the world to deliver high-capacity,
high-frequency wireless connections at 155 Mbps in the 38 GHz frequency band,
and now we continue to maintain our leadership position as the first company to
provide 311 Mbps for commercial

deployment," said Shraga Katz, president and CEO, Ceragon Networks. "At 311
Mbps, our FibeAir 3100 not only exceeds all other commercial system speeds, but
it also drives additional revenue for our customers by optimizing resources."

   "As a rapidly expanding competitive service provider, our challenge is to
quickly and cost-effectively deploy flexible and reliable broadband networks,"
said Luis Rodriguez, COO, FirstMark Comunicaciones Espana. "The Ceragon FibeAir
3100 helps accomplish this by allowing us to easily double our network capacity
when we need to, without using more spectrum."

   Ceragon's 311 Mbps systems uses a single channel to transport high-speed
Internet access and integrated data, video and voice services. These higher
capacity systems offer customers deployment flexibility with a variety of
interfaces (OC-3/STM-1, Fast Ethernet and DS3/E3), frequency bands (18, 23, 26,
28, 29, 31 and 38 GHz) and transport protocols (IP, SONET/SDH, ATM) within a
modular system architecture. The scalable FibeAir 3100 is the industry's first
commercially proven high-frequency system with capacity that can be expanded
from 155 to 311 Mbps.
