Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Shahid Siddiqui\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0071455051\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780071455053\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e McGraw-Hill Companies\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/01\/2005\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 324\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.26lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.08h x 6.32w x 1.07d","brand":"Shahid Siddiqui","offers":[{"title":"Hardcover","offer_id":47202617950463,"sku":"9780071455053","price":131.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f3846697-dda1-46cb-afb0-1100f803afbb.jpg?v=1756832892","url":"https:\/\/www.whiterainbookhouse.com\/products\/roaming-in-wireless-networks-shahid-siddiqui-9780071455053","provider":"WR Book House","version":"1.0","type":"link"}
