We are looking at producing a 10W LTE to meat the requirements of release 11. consideration for release 12- 15 should be provided. design with an integrated EnodeB and BBU design objectives - 1) small footprint 25cx X 25cm to fit inside a pole - reasonable vertical height available for design 2) reliability under extreme conditions - high heat, limited air flow, high humidity etc. 3) LTE EnodeB and BBU unit should be of same footprint and possible Plugged together? top to bottom. 4) TDD capability a primary priority (frequency / band coverage should be "Chip" dependant ie base unit supports any frequency chip installed. 5) 40Mhz, in 20Mhz blocks (ideally 60Mhz perhaps as a field implemented optional upgrade?) 6) option for a FDD EnodeB to connect to same BBU - ie support both TDD and FDD from same transmitter location. 7) as low power consumption as possible.(note no room for any equipment at base of Pole ? 8) Transmitter areal plugged external either Omni- areal or Directional, high gain 9) transmitters should be designed for maximum gain at 10w or 15w of power - knowledge of DB output etc required. 10) Drawings and IP will be transferred to purchaser (me). 11) Time to design a issue? estimate should be provided. we are planning to manufacture units and want to "Buy" the working design. We are not available for a per unit Royalty will also consider bidders who bid on certain parts ie EnodeB, BBU or transmitters separately
