Many countries across the Caribbean are keen to improve the wireless broadband service available and either have offered, or are in the process of offering, the 700 MHz band for use. This post discusses the 700 MHz band, the services being considered, and some other considerations.<\/em><\/p>\n <\/a>In any of our posts where we discuss the penetration of mobile\/cellular services across the Caribbean, it is readily acknowledged that there is widespread proliferation. In our most recent Snapshot: 2012 update on the state of telecoms in the Caribbean<\/em><\/strong><\/a>, the availability of mobile\/cellular service ranged from around 65 subscriptions per 100 of the population in Belize, to approximately 166 subscriptions per 100 of the population in Antigua and Barbuda.<\/p>\n Having made significant inroads in improving access to and the availability of voice services via the mobile\/cellular telephone, many Caribbean countries are now keen to broaden the emphasis to the delivery of broadband services. To varying degrees, mobile broadband services currently exist across the region. However, they tend to be limited in geographic coverage; offer few service plans; and are relatively expensive.<\/p>\n Generally, currently used technologies in the region tend not to have the needed capacity to support a comprehensive rollout of quality mobile broadband, specifically high speed broadband. Hence many countries worldwide are allocating new frequency bands from their national radio frequency spectrum for those services. One of the preferred bands is the 700 MHz band, which countries across the region \u2013 such as Antigua and Barbuda, the five ECTEL Member States, Jamaica and Trinidad and Tobago \u2013 have allocated for Broadband Wireless Access.<\/p>\n <\/a>The International Telecommunications Union (ITU)<\/a> Frequency Allocation Tables, which specifies the approved services that can be used by particular radio frequency bands worldwide, allocated the 700 MHz band primarily for broadcasting, but it could also be used for fixed wireless and mobile services. Historically, this band was used for analogue television (TV) broadcasting on UHF (Ultra High Frequency) channels 52 to 69. The switchover to digital TV means that frequencies initially assigned for analogue broadcasting are being freed up for reuse for other services.<\/p>\n The 700 MHz band is adjacent to the remaining analogue TV channels, and as a result, it possesses excellent propagation characteristics, such as being able to penetrate buildings and walls easily, and covering relatively large geographic areas without unacceptable deterioration of the signal. It therefore means that the 700 MHz band can facilitate more economical deployment of wireless networks, since fewer base stations would typically be required to serve a large area, when compared with that required for the provision of mobile\/cellular service, which tend to use much higher frequencies (e.g. the 900 MHz and 1800 MHz bands).<\/p>\n As the term suggests, Broadband Wireless Access (BWA) speaks to wireless technologies that support data access at broadband speeds, i.e. speeds greater than 2 Mbps (Source: ETSI<\/a>). Across the Caribbean, the major mobile\/cellular operators initially offered Internet connectivity via EGDE, a 2.75G standard, but over the last two years, many have been upgrading their networks to the HSPA+ standard, which is loosely considered a 4G technology. Table 1 compares the most commonly deployed wireless Internet\/broadband technologies, and our earlier post, EDGE, WiMAX, 3G or 4G \u2013 what\u2019s the difference?<\/em><\/strong><\/a>, provides a comprehensive discussion of the various standards.<\/p>\nThe 700 MHz spectrum<\/h3>\n
