This issue is typically solved with GPS or a Precise Network Timing protocol over the packet network, using techniques such as Synchronous Ethernet or 1588v2. In many urban environments, GPS is not a reliable or practical solution. To use Precise Network Timing protocols, all the network devices in the backhaul system must sup- port it. 1588v2 is one of the most common Precise Network Timing protocols used, and will likely be deployed in more than half of net- works within the next 24 months. It is popular because it supports both frequency and time-of-day synchro- nization, which is required by many new telecommunications systems, such as LTE and LTE-A. These sys- tems typically require about 1.5 ms of timing accuracy. Since there are multiple devices along the backhaul path, each device in the path typi- cally requires about 50 ns of tim- ing accuracy. Conveying Precision Timing Protocol over microwave systems was often the weak link in the chain, due to traditionally high Packet Delay Variations. To overcome this limitation, microwave radios systems should support Precision Timing Protocols such as 1588v2. Cambium Networks is committed to providing high- performance wireless broadband connectivity that is also secure and affordable. The new PTP 650 now supports optional 1588v2 Transparent Clock as well as Synchronous Ethernet. In tests, the PTP 650 has achieved up to 2.8 ns of timing accuracy. This is at least 10 times better than most systems would require and ensures that the system addresses any future requirements. The Cambium Networks PTP 650 is a revolutionary Sub-6 GHz (4940-6050 MHz) point-to- point microwave radio with up to 450 Mbps of throughput. The PTP 650 1588v2 Transparent Clock is particularly useful for applications requiring synchronization and tim- ing, such as LTE Backhaul, Cell-on- Wheels, Small Cell Backhaul and FirstNet Backhaul.

Those services are delivered across the most extensive wireless networks in the Canadian industry. Bell's 4G High-speed Packet Access (HSPA+) network is as good as any in the world, with a footprint that covers 97 percent of the population. We continue to improve it with HSPA+ Dual Cell technology which doubles the network's data transfer speed up to 42 Mbps. Dual cell is available to 70 percent of the HSPA+ footprint. An established leader of Canadian wireless, Bell continues to innovate, most recently with the launch of an even faster network - 4G LTE (Long-Term Evolution) - which will eventually support speeds approaching 150 Mbps. Bell Mobility Inc. provides wireless communications services across Canada under the Bell Mobility and Solo Mobile brands. Bell also owns 100 percent of Virgin Mobile Canada and offers wireless services under the Virgin brand nationally. About Ceragon Networks Ltd.
