Comparision between Nanostation2 and NS2 Loco
NS2 has
Integrated 10dBi Dual Pol + External SMA antenna and connector
TX Power 26dBm, +/-2dB
RX Sensitivity -97dBm +/-2dB
NS2 Loco has?
Antenna Integrated 10dBi Dual Pol
TX Power 20dBm, +/-1dB
RX Sensitivity -95dBm +/-1dB
Now let's check distances
IN NS2 it is over 15 km
In loco it is Over 5Km.
Conclusion:
Loco is cheap but not good for long distances. You may use it with in 2-3 miles by using 802.11b

#Rebuilding the kernel
#To rebuild the default kernel from stable:
cd /usr/src/sys/arch/i386/conf
/usr/sbin/config GENERIC
cd /usr/src/sys/arch/i386/compile/GENERIC
make clean && make depend && make
#Replace i386 with your architecture, e.g. sparc, alpha, etc.
#Rebooting with the new kernel
#To reboot with the newly compiled kernel:
cd /usr/src/sys/arch/i386/compile/GENERIC
cp /bsd /bsd.old (Save an old copy of your kernel)
cp bsd /bsd (Copy the new kernel into place)
reboot
#As above, substitute your architecture for i386. If your system has trouble booting the new kernel, you can easily go back and reboot from the old kernel, now called bsd.old.
#Rebuilding the binaries
#To rebuild the system binaries:
rm -rf /usr/obj/*
cd /usr/src
make obj
cd /usr/src/etc && env DESTDIR=/ make distrib-dirs
cd /usr/src
make build
#This will take awhile...
