The last hundred years has seen vast changes in our use of wireless communications. What previously was just used by military and public safety organizations-hand-held communi- cation devices-are now de rigueur for 21st century tweens. Not only do a large percentage of Americans own a personal wireless device, many have access to multiple wireless devices. The demand for information at fast speeds with lots of data, wherever a person happens to be, is not expected to wane any time soon. The need for high performance from a small device we can hold in our hand, mount in our car, or rely on at the network's edge is paramount. The demands for increased coverage and capacity, as well as enhancements in technology, continue to intro- duce new challenges to our outdoor networks. Infrastructure: Macro Sites Demand for more capacity and better cover- age, as well as changes in wireless technology, drive equipment changes and additions at the foundation of most wireless networks-the macro site. Whether adding or replacing antennas or adding remote radio heads to the tower, equipment modifications can impact weight and wind loads. See the CommScope article on page two for a full discussion of the key areas for consideration when upgrading or retrofitting an existing site. Infrastructure: Micro Sites More and more applications are utilizing wire- less technology, and the applications are using increased bandwidth. The need for improved wireless coverage and capacity is expanding. From cellular and Wi-Fi to private networks, demand is driving the need for additional com- munication sites. Unfortunately, the place your network requires additional coverage may not be conducive to a new tower site. Rooftops, wood poles, metal poles, kiosks and the sides of build- ings start to come into play. These may present the best option for a micro site, especially in densely-populated areas. Developing micro sites involves many consid- erations.

Based on Ceragon's com- pact, multi-core FibeAir IP-20C solution, the live link provides 1.6 Gbps of capacity over a single 40MHz channel. By selecting Ceragon's advanced microwave solutions, Bell Mobility aims to more than double the capacity of its wireless backhaul network. Approximately 30 percent of all Bell Mobility cell sites are connected to the net- work via microwave since fiber is not always available or cost effective, especially in rural parts of the country. As new mobile technolo- gies gain support and popularity, there is a clear need for an increase in backhaul capac- ity over microwave. The use of a single frequency channel to achieve ultra-high capacities is extremely important for mobile operators as there is a finite amount of the spectrum available. While competing solutions claim to achieve gigabit bandwidth through the use of multiple frequencies, it is not always possible for operators to license multiple frequencies where and when the additional bandwidth is required. "Bell Mobility is taking big steps toward preparing their network to haul LTE Advanced and even 5G future services," said Ira Palti, president and CEO of Ceragon. "Our compact FibeAir IP-20C solution is the only system to- day capable of delivering multi gigabit capaci- ties over a single licensed frequency channel. FibeAir IP-20C provides the flexibility that mobile carriers need in order to meet diverse deployment scenarios in both urban and rural settings." About Bell Mobility Bell Mobility is a division of Bell Canada (Bell). Bell offers consumer and business custom- ers across Canada blazing fast speeds, high quality coast-to-coast coverage and global "As new mobile technologies gain support and popularity, there is a clear need for an increase in backhaul capacity over microwave.''
