    101101|| 4.1  || "GENI Operator ID":  Each WiMAX deployment requires an Operator ID (OpID), a parameter used within the base station and each client.  Currently, Routgers WINLAB is using the Sprint/Clearwire ID, but this can only be temporary.  We need to apply for and receive a "GENI Operator ID".  ||  Michel  ||  2/23/10  || -  || -  || Per Seskar, apply at [https://standards.ieee.org/regauth/BOPID/Broadband_OperatorID_Request_Form.html IEEE 802.16 site].  Fee is $1200.||
    102102|| 4.2  ||   Range and capacity:  Need to be able to estimate the expected range and capacity of a completed installation, and how this varies with antenna height, to guide each campus in their planning.  Also, how this varies depending on the number of clients and their data rates. ||  Michel, Seskar  ||  2/23/10  || -  || -  || Seskar:  Have some data from Rutgers WINLAB site, and expect more when Rutgers Bush Campus site is in service. Can configure split between downstream and upstream.  With 10MHz bandwidth, limited to approximately 20Mbps total.  Have seen range approximately x10 of WiFi range.  Have seen downstream of 2+Mbs at 2km combined with 7Mbs at short distances.  NEC will not release their range info.  Need to check open WiMAX literature, and measure.  ||
    103 || 4.3  ||   GPS receiver:  NEC documentation shows a GPS receiver mounted along with the antenna, and connected to the NW INTFC on the IDU.  It provides precise timing signals to the base station.  On 2/23, we agreed to include in the kit, since total cost is likely to be less than $125, and it should be installed at the start.  ||  Michel, Seskar ||  2/23/10  || -  || -  || Need to engineer active antenna and cable for up to 100m, and need a BOM for active antenna, arrestor and cable. ||

    104104|| 4.4  ||   "GENI PKI Certificate":  If we want to do over-the-air provisioning to clients, we will require a PKI certifiacte signed by Verisign, that clients can verify (per Seskar).  ||  Michel ||  2/23/10  || -  || -  || Need to decide how GENI would use this;  if worthwhile, then plan process to obtain one.  ||
