our customers in the mobile operator market using our current technology and service capabilities . the market for mobile backhaul continues to be our primary addressable market segment and the demand for increasing the backhaul capacity in our customers ' networks continues to grow in line with our expectations . in fiscal 2013 we saw sustained demand in north america as we supported the long-term evolution ( “ lte ” ) deployments of our mobile operator customers . internationally , our business continued to rely on a combination of customers increasing their capacity to handle subscriber growth , the ongoing build-out of some large 3g deployments , and the emergence of early stage lte deployments . our objective continues to be to position aviat networks to support our customers for

differentiating factor in serving new business and enabling us to expand our business with existing customers across all markets . during fiscal 2013 , our growth in revenue over fiscal 2012 was predominantly attributable to an increase in service orders in north america and 27 africa . however , as disclosed above and in the “ risk factors ” section in item 1a of this annual report on form 10-k , a number of factors could prevent us from achieving our objectives , including ongoing pricing pressures attributable to competition and macroeconomic conditions in the geographic markets that

the fiscal 2013-2014 plan during fiscal 2014. see “ restructuring charges ” below . revenue we manage our sales activities primarily on a geographic basis in north america and three international geographic regions : ( 1 ) africa and middle east , ( 2 ) europe and russia and ( 3 ) latin america and asia pacific . revenue by region for fiscal 2013 , 2012 and 2011 and the related changes are shown in the table below : replace_table_token_6_th our revenue in north america increased $ 15.6 million , or 9.5 % , in fiscal 2013 compared with fiscal 2012 . in fiscal 2013 , we saw improved sales to north american mobile operators which were attributable to their ongoing buildout of lte networks in the region . at the same time , north america sales to non-mobile customers , such as power utilities and state and local government private networks , were flat in fiscal 2013 compared with fiscal 2012. our revenue in north america increased $ 4.5 million , or 2.8 % , in fiscal 2012 compared with fiscal 2011 . we have seen substantial changes in product mix of our sales in this region from year to year . the bulk of our product revenue in north america came from our eclipse product platform , whereas in the first half of fiscal 2011 , our legacy products made up a significant portion of the region 's sales . the revenue growth and product mix changes reflect continued success in transitioning our customer base to the new product platform as well as an increase in our services business from major customers in fiscal 2012. our revenue in africa and middle east increased $ 34.5 million , or 23.4 % , in fiscal 2013 compared with fiscal 2012. the majority of the increase came in the first half of fiscal 2013 and was attributable to demand from mobile operator customers in africa investing in network transmission capacity in order to accommodate growth in network data traffic and to increase their service competitiveness . revenue from mobile operators in europe and russia declined $ 5.6 million , or 10.4 % , in fiscal 2013 compared with fiscal 2012. we believe the decrease was related to economic difficulties experienced generally throughout europe . revenue in latin america and asia pacific declined $ 17.2 million , or 22.1 % , in fiscal 2013 compared with fiscal 2012. the decrease was primarily due to a decline in customer purchases in asia as some of our larger customers , who are beginning to roll out lte service , continue to deploy large orders that we delivered in the past year . our international revenue declined $ 12.6 million , or 4.3 % , in fiscal 2012 compared with fiscal 2011. our business in asia and latin america showed improvement in fiscal 2012 from increased orders from network operators . however , our sales in europe and russia were down from fiscal 2011 primarily due to the reduction of business with a major customer in russia who took substantial deliveries in fiscal 2011 , partially offset by increased orders and sales to wireless network operators in other european countries . in fiscal 2012 , we experienced substantially increased sales with our long-term customers in africa , offsetting the reduced volume in the middle east . africa continued to be our strongest international sector , where we continued to compete successfully for wireless infrastructure business of large network operators , particularly in west africa . our revenue from product sales increased $ 1.2 million , or 0.4 % , in fiscal 2013 compared with fiscal 2012. the increase came primarily from strong sales in africa , offset in part by reductions in asia pacific , europe and a small year-to-year decrease in north america . story_separator_special_tag ) minimum consolidated ebitda measured for each fiscal quarter .
